SYMP-01 Changing paradigms in plant breeding by new plant breeding technologies Ju-Kyung Yu Syngenta Seeds, USA Plant breeding is based on understanding genetics and mechanical systems to improve crop production. During the last century, conventional plant breeding, mostly based in the evaluation at the phenotypic level, had been successful in increasing crop yields. Within the last two decades there has been significant crop improvement due to the application of molecular genetics and genomics to improve efficiency and accuracy in plant breeding. One of the key global challenges of the 21st century is the production of enough food for an ever increasing world population. Agricultural productivity needs to be increased while addressing the issues of scarcity of arable land and water, impact of changing climate and preservation of natural resources. Improvement of crop yields on limited agricultural resources requires concerted efforts using scientific and technological advances in multiple disciplines. Multidisciplinary approaches are being conducted to enhance crop improvement and meet resource needs. This session will address new plant breeding paradigms through the integration of multiple perspectives. The paradigm shift has occurred through the integration of five key components for crop improvement: 1) continued improvement of genomic tools, 2) information technology including open source data, 3) advanced analytical methods such as mathematical modeling and simulation, 4) adaption of non-crop information, and 5) increased importance of breeding operation enhancement. -3-
SYMP-02 Current Status of Seed Industry and Crop Breeding Strategies Chee-Hark Harn Nongwoo Bio Co., Korea Crop produce comes from seeds. It is important to have elite seeds for cultivation and harvesting. There are two major types of seeds in the seed market: F1 hybrid seeds and open-pollinated seeds (OP, traditionally pollinated). Farmers in developed countries plant F1 hybrid in most cases, while farmers in developing countries plant mainly OP. In fact, 60-70% of seeds planted in India and China are OP because OP is significantly cheaper. There are several reasons why the seed industry is important. First is for global food security. Based on the fact that the global population continues to increase steadily, additional productivity of 70% will be required to feed the global population by the year 2050. Second, seeds were traditionally used as food, both fresh and feed, but have now become materials for future industries of medicine, pharmaceutics, functional foods, energy, and may other applications. Third, new breeding programs based on biotechnology have changed the seed market dramatically. These programs are highly competitive and indeed play a major role, not only in the reduction of breeding time, the development of various genetic sources, the enhancement of purity and cost-saving, but also for the selection of value-added varieties. In Korea, F1 breeding began 65 years ago and the breeding programs for several vegetables and rice are in the top class worldwide. In addition, for the first time in 1999, a private seed company in Korea employed biotechnology for the purpose of crop breeding to develop platform technologies that could be utilized in the breeding practice. The major achievement so far is the development of DNA markers associated with resistance to disease, tolerance to the environment, and functional aspects. The application of genotyping has made many services possible, such as the purity control of F1 and inbred lines, variety verification, MAS (marker assisted selection), and MAB (marker assisted backcrossing). In addition, cell fusion and DH technologies have helped breeders to solve breeding limitations. There have been many cases of successful crop transformations, however, no GM varieties have been successfully commercialized in Korea. I bet this is inevitable, though. And it should be, because Korea imports lots of GM products, equivalent to $3 billion every year. More seed production and higher crop quality require new R&D strategies for breeding practices in the seed industry. Thanks to genomics information with big data and anti-gmo policies, new technologies are on the horizon, including genomic breeding, genome editing, in silico breeding and NBT (new plant breeding technology). I am going to talk more about the direction and strategy of R&D for crop breeding. -4-
SYMP-03 Global Marketing Strategies for Globalization of Seed Industry Kyoung Ou Ryu Asia Seed Co. Ltd., Korea The size of the global seed market and the volume of seed trading have rapidly increased in the 21st century where the total market size by 2012 was approximately 45 billion USD, of which 79% were field crops, 17% were vegetables and 4% were forage and turf. While the volume of the trade and the market as a whole expanded, the share of the market also changed as the top 9 largest seed companies controlled 62% of the market in 2012 as opposed to just 17% in 1996. As for the regional status of the market size, North America and Asia-Pacific regions had 69% of the total market worth in 2014. The changes in the seed market led to various adjustments in the seed trading regulations where the protective behaviors of major players affected the entire market. Asia Seed Co., Ltd. is a vegetable seed company founded in 1992 and is thriving each year in exporting new hybrid vegetable seeds to clients around the world. As a second mover to the saturated market that is dominated by a few companies with large shares, the company has set up four major strategies to compete in the global market. First and the most important strategy is to increase investment in R&D portion and strengthen it. In most types of businesses, investing in R&D is the key to success. Especially in the vegetable seed industry, the competitiveness of a company is decided by the variety of its seeds that result from the R&D department. The second strategy is the localization and incorporation of the company. Globally, vegetable crops vary while the domestic Korean varieties are not even known in other countries. To overcome this problem, it is important to open branches and subsidiaries to enter the market with local types of varieties that will appeal to customers and farmers. In relationship to R&D investment, Asia Seed Co., Ltd. has already set up a breeding system in India and keep expanding to other nations as well. The third strategy is to develop new materials for both the niche market and new possibilities. The last strategy is to have manpower training system that is required in all other industries. In order to assess the performance of our hybrid seeds, trained managers will need to travel and visit plots to acquire the results of trial and offer instructions when they are not satisfactory. Moreover, it is essential for collecting genetic materials from around the globe in order to develop better hybrids for the future of the company. Seed exporting, while difficult, can be a charming and lucrative business. With enthusiasm in dealing with challenges and opportunities, I will contribute more ideas and know-hows on how the company deals with those choices and possibilities. *Corresponding Author: E-mail: ceo@asiaseed.co.kr -5-
SYMP-04 Geno-Pheno in plant breeding Dani Zamir The Hebrew University of Jerusalem, Faculty of Agriculture, Israel In crop genetics and breeding research, phenotypic data are collected for each plant genotype, often in multiple locations and field conditions, in search of the genomic regions that confer improved traits. Currently, virtually none of the data generated from the hundreds of phenotypic studies conducted each year are being made publically available as raw data; thus there is little we can learn from past experience when making decisions about how to breed better crops for the future. This ongoing loss of phenotypic information, particularly about crop productivity, must be stopped if we are to meet the considerable challenge of increasing food production sufficiently to meet the needs of a growing world population. I will present a number of plant-breeding case studies that demonstrate the value of introgressions from wild tomato species and of sharing information on crop plant genotypes and phenotypes. *Corresponding Author: Tel. +972 8 948 9092, E-mail: dani.zamir@mail.huji.ac.il -6-
SYMP-05 Understanding Oryza Genomes to maximize Genetic Variations for Crop Improvement Yeisoo Yu Phyzen Genomics Institute, Phyzen Inc., Korea Next generation sequencing (NGS) technologies provide a fast and easy way to understand the plant genomes, transcriptomes, regulatory elements and their interactions. About a decade ago, rice was the only crop that whole genome sequence information was publicly available but today many agricultural crops including maize, soybean, tomato, potato, cotton have been sequenced and many more will be available. Moreover newly developed method such as Genotyping-By-Sequencing (GBS) allows efficiently collecting sequence information from hundreds of individuals in population to identify genetic variations, detect quantitative trait loci (QTLs) and develop molecular markers. Coupled with high-throughput phenotyping, the accumulated genomic information will be effectively utilized in crop improvement by genomics-assisted breeding, genome-wide association mapping (GWAS) and genomic selection (GS). Rice is one of the important staple crops providing daily nutrition to more than a half of the world population. The genus Oryza consists of 23 species including two domesticated rice and it has been classified into 10 distinct genome types, represented by six diploids (A, B, C, E, F, and G) and four allotetraploids (BBCC, CCDD, HHJJ, and HHKK). It shows wide ranges of phenotypic variations to biotic and abiotic stress thus is considered a genetic reservoir of unique allelic variation for rice improvement. International collaborative efforts have been focused on generating the Oryza genomics resources including reference genome, transcriptome, smallrnas, methylome and resequencing of many accessions to collect genetic variations and better understand the 15 MY evolution of Oryza. The Oryza genomic resources will be a backbone to layer various omics data to catalogue more genetic variations within and between Oryza species and the untapped genetic diversities existing in wild Oryza species will be finally translated to crop improvement. -7-
SYMP-06 Small RNA studies reveal a role for mirnas and their targets in the regulation of NB-LRR disease resistance genes in pepper June Hyun Park 1, Igojo Kang 1, Chanseok Shin 1,2,3* 1 Department of Agricultural Biotechnology, Seoul National University, Seoul, 151-921, Republic of Korea, 2 Research Institute of Agriculture and Life Sciences, 3 Plant Genomics and Breeding Institute, Seoul National University, Seoul, 151-921, Republic of Korea MicroRNAs (mirnas) are a class of non-coding RNAs approximately 21-nt in length which play important roles in regulating gene expression in plants. Although many mirna studies have focused on a few model plants, mirnas and their target genes remain largely unknown in hot pepper (Capsicum annuum), one of the most important crops cultivated worldwide. We here employed high-throughput sequencing to comprehensively identify small RNAs and their targets in pepper. From these, we identified several novel targets of mirnas, including the major de novo methylation enzyme involved in RNA-directed DNA methylation in plants. Furthermore, we identified several highly abundant 22-nt mirna families that target conserved domains in NB-LRRs. We showed that transient co-expression of the mirna with NB-LRRs, resulted in the attenuation of the hypersenstive responses in Nicotiana benthamiana, suggesting that interaction between mirna family and disease resistance proteins is likely to serve as a conserved trigger for defense mechanism in Solanaceae. This work provides the first reliable draft of the small RNA transcriptome in pepper that offers an expanded picture of mirnas in relation to NB-LRR regulation, providing a basis for understanding the functional roles of mirnas in disease resistance. -8-
SYMP-07 RNA-guided Genome Editing in Animals and Plants Jin-Soo Kim Center for Genome Engineering, Institute for Basic Science, Seoul, South Korea Department of Chemistry, Seoul National University, Seoul, South Korea Genome editing that allows targeted mutagenesis in higher eukaryotic cells and organisms is broadly useful in biology, biotechnology, and medicine. We have developed zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and Cas9 RNA-guided engineered nucleases (RGENs), derived from the type II CRISPR/Cas prokaryotic adaptive immune system, to cleave chromosomal DNA in a targeted manner, producing DNA double-strand breaks in cells, the repair of which via endogenous systems gives rise to targeted genome modifications. The Cas9 protein, when complexed with small guide RNAs (sgrnas), recognizes and cleaves target DNA sequences complementary to the guide RNAs in vivo, inducing targeted genome modifications at high frequencies in cultured cells and whole organisms. Despite broad interest in RNA-guided genome editing, RGENs are limited by off-target mutations. Here, we show that off-target effects of RGENs can be reduced below the detection limits of deep sequencing by choosing unique target sequences in the genome and modifying both guide RNA and Cas9. Furthermore, we deliver purified recombinant Cas9 protein complexed with sgrnas (RGEN ribonucleoproteins (RNPs)) to animal embryos and cultured human cells including hard-to-transfect pluripotent stem cells to achieve highly efficient RNA-guided genome editing in cells and whole organisms. RGEN RNPs cleave chromosomal DNA almost immediately after delivery and are degraded rapidly in cells, reducing off-target effects and mosaicism. -9-
SYMP-08 High-throughput phenotype analysis of transgenic plants for product development Dan Sung Yield trait program, Monsanto, 110 TW Alexander Dr, RTP NC 27709 The world population is projected to reach to 9.6 billion people by 2050. With increasing population and improving living standards, the demand for food is accelerating. In order to meet increasing demand for food while the arable land and other resources are decreasing, agriculture needs all the tools available to sustainably increase crop yields. Development of effective GM traits to protect crops from abiotic and biotic stressors is a critical aspect of sustainable yield improvement. Efficient identification of traits and rapid integration of the traits into commercial elite germplasm requires robust and rapid traits testing. Monsanto have developed numerous high-throughput phenotyping platforms to support rapid trait identification and integration. Selected phenotyping platforms will be reviewed to gain understanding on how they are utilized for trait phenotyping. -10-
SYMP-09 Spectral Imaging Technologies for Assessment of Plant Characteristics Moon S. Kim Environmental Microbial and Food Safety Laboratory Agricultural Research Service, USDA, 10300 Baltimore Ave. Beltsville MD 20705 USA Moon.Kim@ARS.USDA.GOV Many spectral imaging technologies are available to nondestructive means to assess plant status including abiotic and biotic stress conditions. In recent years, ARS has developed various sensing and instrumentation technologies for agricultural applications. These include hyperspectral imaging for visible/near-infrared (NIR) reflectance and fluorescence imaging, and multispectral laser-induced fluorescence imaging. Hyperspectral imagery is a fusion of imaging and traditional spectroscopy. We recently expanded the hyperspectral capabilities to include rapid macro-scale Raman chemical imaging. The current state of the art of imaging technologies and their potential applications for characterization of the plant status are presented. -11-

OA-01 QTL mapping of Fusarium wilt resistance in radish (Raphanus sativus L.) Xiaona Yu, Su Ryun Choi, Yong Pyo Lim * Molecular Genetics and Genomics Laboratory, Department of Horticulture, Chungnam National University, Daejeon 305-764, Korea Fusarium wilt (FW), caused by the soil-borne fungal pathogen Fusarium oxysporum is a serious disease in cruciferous plants, including the radish (Raphanus sativus). To identify quantitative trait loci (QTL) or gene(s) conferring resistance to FW, we constructed a genetic map of R. sativus using an F 2 mapping population derived by crossing the inbred lines 835 (susceptible) and B2 (resistant). A total of 220 markers distributed in 9 linkage groups (LGs) were mapped in the Raphanus genome, covering a distance of 1041.5 cm with an average distance between adjacent markers of 4.7 cm. Comparative analysis of the R. sativus genome with that of Arabidopsis thaliana and Brassica rapa revealed 21 and 22 conserved syntenic regions, respectively. QTL mapping detected a total of 8 loci conferring FW resistance that were distributed on 4 LGs, namely, 2, 3, 6, and 7 of the Raphanus genome. Of the detected QTL, 3 QTLs (2 on LG 3 and 1 on LG 7) were constitutively detected throughout the 2-years experiment. QTL analysis of LG 3, flanked by ACMP0609 and cnu_mbrpgm0085, showed a comparatively higher logarithm of the odds (LOD) value and percentage of phenotypic variation. Synteny analysis using the linked markers to this QTL showed homology to A. thaliana chromosome 3, which contains disease-resistance gene clusters, suggesting conservation of resistance genes between them.

OA-02 Existence of qualitative resistance against blackleg disease in Brassica oleracea L. and detection of gene-specific single nucleotide polymorphism Arif Hasan Khan Robin, Jong-In Park, Nasar Uddin Ahmed, Rawnak Laila, Ill-Sup Nou * Department of Horticulture, Sunchon National University Blackleg disease caused by Leptosphaeria maculans, is the most devastating disease of Brassica germplam worldwide that causes million tonnes of crop losses per year throughout the world. To date, a total of 12 race-specific resistance genes of Brassica napus to L. maculans have been reported but linkage mapping analysis reveals that all of those loci are located in A genome i.e., in B. rapa chromosomes. B. oleracea has high ancestral synteny with B. rapa through their evolution. We believe that presence of qualitative resistance is possible in B. oleracea germplasm. The present study was therefore planned to find out any race-specific qualitative resistance gene present in C genome of B. oleracea. A total of 16 microsatellite markers were used which are linked to seven different Rlm and Lep genes of B. napus to screen 32 inbred lines of cabbage. Primers were designed based on homology assessment in corresponding nucleotide sequence available in Bolbase (a B. oleracea genome database, http://www.ocri-genomics.org/bolbase/index.html), located in B. oleracea scaffolds/chromosomes. Out of 16 SSR markers, 13 were found polymorphic which indicates possible existence of resistant genes in cabbage lines. The inbred lines are then assessed against two L. maculans stains with known avirulent genes. Some inbred lines were hypersensitive against gene-specific virulent strains of L. maculans that confirmed existence of Rlm1, Rlm2, Rlm4, LepR3 and LepR4 in the cabbage lines. In this way we were able to select out resistant and susceptible lines against each resistant gene. The gene-specific polymorphic SSR marker regions were cloned and sequenced and candidate SNPs were identified for confirmation of their functionality. *Corresponding Author: E-mail: nis@sunchon.ac.kr -16-
OA-03 Expression profiling of two contrasting bulb onion lines (Allium cepa L.) under Photoperiod and Drought Conditions Ranjith Kumar Manoharan, Jeong Suk Hyeon Han, Senthil Kumar Thamilarasan, Jong-In Park, Ill-Sup Nou * Department of Horticulture, Sunchon National University, Suncheon, Jeonnam 540-950, Republic of Korea Onion and other Allium vegetables have been valued since antiquity for their pungent flavor and aroma. Modern science has confirmed traditional benefits that the organosulfur compounds that impart flavor also confer significant human health benefits such as reduced blood clotting and antimicrobial properties. Glucose, fructose and sucrose comprises majority of onion bulb dry matter content. The sugars, pyruvic acid accumulation and transcript level of some transcription factors involved in the biosynthesis of high sugars and pyruvic acid. These profiles were compared with two different lines 36101 (early) and 36122(Late) of bulb onion (Allium cepa L.) growing under drought and photoperiod condition using High Performance Liquid Chromatography (HPLC) and Quantitative real time PCR using FT genes. We identified the gene AcFT4 was responsible for early and late bulb intiation in the onion lines. The cultivar lines 36101and 36122 were used to identify potential genes controlling pungency and sugar. The comparative analysis of two lines showed significant positive phenotypic and genetic correlations. Sugar and pungency profile showed significant difference between two lines. FT gene expression and pungency level was high in onion lines during drought stress. In this study, we proposed the biochemical characterization of two line and genes involved in the bulb formation were also studied. There is a correlation between sugars and pungency level during the drought stress. These results could be presumably used as useful information to obtain onion varieties rich in sugars and pungency.

OA-04 TIFY family genes in Chinese cabbage (Brassica rapa ssp. pekinensis): A Genome-wide analysis reveals their stress and hormone responsive patterns Gopal Saha, Jong-In Park, Nasar Uddin Ahmed, Md. Abdul Kayum, Ill-Sup Nou * Department of Horticulture, Sunchon National University, Sunchon 540-950, Korea The TIFY family is composed of a plant-specific group of genes with diversity of functions. This family represents four subfamily of proteins viz. ZML, TIFY, PPD and JASMONATE ZIM-domain (JAZ) proteins. TIFY proteins especially, JAZ proteins have been reported to perform different biological processes, such as developmental and stresses and hormone responses in Arabidopsis and rice. However, there is no information about this family genes in Brassicaceae. This study identifies 36 TIFY genes in Brassica rapa, an economically important crop species from this family. An extensive in silico analysis through phylogenetic grouping, protein motif organization and intron-exon distribution also confirmed 4 subfamilies of BrTIFY proteins. Out of 35 BrTIFY genes, we identified 21 under JAZ subfamily besides 7 TIFY, 6 ZML and 2 PPD. An extensive expression profiling of 21 BrTIFY JAZs both in tissues and organs of B. rapa revealed differential expression patterns. Almost all the BrTIFY JAZs predominantly expressed in leaves and flower buds. Besides, in a flower stage specific expression analysis we observed 14 BrTIFY JAZs with constitutive expression patterns. This indicates BrTIFY proteins have a strong involvement in the development of B. rapa flowers. Our protein interaction study also reveals the strong association of these proteins with the fertility and defense processes of B. rapa. To elucidate the stress responsiveness of BrTIFY genes, we analyzed the low temperature-treated whole-genome microarray data set and found almost all the BrTIFY JAZs were having variable transcript abundance in two contrasting inbred lines of B. rapa. Subsequently, all 21 BrTIFY JAZs were validated in response to cold stress in the same two lines via qpcr, where 9 genes were found to show up- regulation. And, a high and differential qpcr expression pattern of all the BrTIFY JAZs was also recorded against JA. Additionally, BrTIFY JAZs were tested against salt, drought, Fusarium, ABA and SA treatments and a considerable number of genes were found to be induced. The extensive annotation and transcriptome profiling reported in this study will be useful for understanding the involvement of TIFY genes in stress resistance and different developmental functions, which ultimately provides the basis for functional characterization and exploitation of the candidate genes for genetic engineering of B. rapa. *Corresponding Author: Tel. +82-61-750-3249, E-mail: nis@sunchon.ac.kr -18-
OA-05 De novo assembly and transcriptome analysis of bulb onion (Allium cepa) during cold acclimation using contrasting genotypes Senthil Kumar Thamilarasan, Jeong Suk Hyeon Han, Jong-In Park, Ill-sup Nou * Department of Horticulture, Sunchon National University, 413 Jungangno, Suncheon, Jeonnam 540-950, Republic of Korea Bulb onion (Allium cepa) is one of the second most widely cultivated and consumed vegetable crops in the world. During winter where the temperature can be as low, plant could get cold injury and limit the production of bulb onion. However, the genomic resources available for bulb onion are still very limited. To date, no studies about heritably durable cold and freezing tolerance were carried out in bulb onion genotypes using high-throughput sequencing technology was applied. We sequenced cold (2 C) freezing (-5 and -15 C) treated and control (25 C) samples of contrasting genotypes of A. cepa lines and obtained 4,52,194,370 total high quality reads. After de novo assembly reads were assembled into 54,047 genes finally generated with an average length of 1,331 bp. Based on the similarity search aligning all genes with known public non-redundant (NR) database, including Swiss-prot, KEGG and COG. Differentially expressed genes (DEGs) were investigated using FPKM method. Overall, 92,862 genes were differentially regulated in all libraries were identified. Additionally, increase our understanding of the DEGs, we performed GO and KEGG pathway enrichment analyses. Based on FDR<=0.01 value in cold freezing tolerant line candidate genes were selected and discussed. Finally 25 candidate genes were examined using qrt-pcr were differentially regulated and known to be associated with cold and freezing stresses. Moreover, in silico prediction of putative molecular marker 4,437 SSRs and 6,076 SNPs. Our study is the first to provide the transcriptome sequence resource of Allium spp., for cold and freezing stress. We identified large set of genes to determine its DEGs profile under cold and freezing condition using two different genotypes. These data provides a valuable resource of genetic and genomic studies of Allium spp. Keywords: Bulb onion, cold, freezing stresses, Transcriptome, de novo, DEGs *Corresponding Author: Tel. +82-61-750-3249, E-mail: nis@sunchon.ac.kr -19-
OA-06 Characterization of regulatory genes for anthocyanin biosynthesis pathway and cold/freezing tolerance in Brassica rapa Nasar Uddin Ahmed, Jong-In Park, Ill-Sup Nou * Department of Horticulture, Sunchon National University, 255 Jungang-ro, Suncheon, Jeonnam 540-950, Republic of Korea Anthocyanins are responsible for vivid colors of flowers, fruits and vegetative tissues and biosynthesis of it is primarily controlled by several structural and regulatory genes. The regulatory mechanism of this pathway is still unknown. This study identified 19 transcription factors of Brassica rapa and investigated their regulatory function in anthocyanin biosynthesis pathway genes and cold and/or freezing tolerance in B. rapa. Expression analysis of these genes in the pigmented and non-pigmented portion of leaves of different lines of B. rapa revealed that BrMYB2-2 and BrTT8 showed responses contrasting with anthocyanin accumulation and cold stress. Sequences of these genes were analyzed and compared with similar gene sequences from other species and a high degree of homology with their respective functions was found. Co-regulated cis -elements were found in promoters of BrPAL1, BrCHS, BrF3H1, BrF3 H1, BrFLS, BrBAN, BrDFR8, BrANS1, and BrMYB2-2 and BrTT8 had binding sites of the promoters of those structural genes. Thus, the above results suggest the association of BrMYB2-2 and BrTT8 with regulation of anthocyanin biosynthesis pathway genes and cold and freezing stress tolerance and might be useful resources for development of cold resistant Brassica crops with desirable colors as well. *Corresponding Author: Tel. +82-61-750-3249, E-mail: nis@sunchon.ac.kr -20-
OB-01 Fine mapping the UV-B resistance gene in soybean using 180K Axiom SoyaSNP assay Sungmin Kim 1, Ju Seok Lee 1, Sumin Park 1, Kyungryun Kim 1, Mijung Cho 1, Eunsil Kim 1, Bo-Keun Ha 2, Sungtaeg Kang 1* 1 Department of Crop Science & Biotechnology, Dankook University, Cheonan, 330-714, Korea 2 Department of Plant Biotechnology, Chonnam National University, Gwangju, 500-757, Korea The depletion of stratospheric ozone has resulted in increased amount of ultraviolet-b radiation (UV-B: 280-320 nm) reaching the Earth s surface and could cause significant biological effect in plants. In this study, putative quantitative trait loci (QTL), which is responsible to UV-B resistance in soybean, was identified using recently developed high-density 180K Axiom SoyaSNP genotyping array. A population of 115 recombinant inbred lines (RILs) derived from a cross between susceptible Keunolkong and resistant Iksan 10 was analyzed. A total 8,970 polymorphic SNP markers were used to construct linkage map. The both parents and RILs were grown with supplemental UV-B radiation in a greenhouse condition. Three categories of UV-B induced morphological damage, degree of leaf chlorosis, leaf shape change, and total plant damage were evaluated. Using composite interval mapping analysis, one major QTL associated with all of the phenotypic traits was detected on 7.7cM of soybean chromosome 7 with 22 of LOD score accounting for about 60% of phenotypic variance. Also, the allele from Iksan 10 were responsible for the UV-B resistance. Thus, the UV-B resistance QTL on chromosome 7 from Iksan 10 was designated to quvbr1, corresponding to 30kb on the Williams 82 genome assembly (Glyma2.0) including 7 candidate genes. This result could be useful in breeding for new foxglove aphid resistant soybean cultivars. In addition, these results provided useful information not only for marker-assisted selection for UV-B resistance soybean, but also for the future identification of putative candidate genes, responsible for UV-B resistance in soybean. *Corresponding Author: Tel. 041-550-3621, E-mail: kangst@dankook.ac.kr -21-
OB-02 Nucleotide polymorphisms in genes controlling panicle development are associated with the number of spikelets per panicle in rice Su Jang, Gileung Lee, Chang Soo Yoo, Hee-Jong Koh * Department of Plant Science, Research Institute of Agriculture and Life Science, and Plant Genomics and Breeding Institute, Seoul National University, Seoul, 151-921, Korea. The number of spikelets per panicle in rice is determined by characters of the panicle such as the number of primary branches (PB) and secondary branches (SB) and panicle length (PL). It is a quantitative traits controlled by several genes. In this study, the nucleotide polymorphism and haplotype diversity of coding region of genes related to number of spikelets per panicle (SPP), including APO1, APO2, FON1, DEP1, GN1a, GHD8, HD1, and SP1, were analyzed using 45 varieties which showed significant phenotypic variations for PL, PB, SB and SPP. Significant correlations were observed among all the panicle traits. A total of 151 polymorphisms, including 114 SNPs and 26 indels were detected in coding region of 8 genes which constructed 52 haplotypes. Neutrality tests revealed that population subdivision event or balancing selection occurred in locus of APO2, FON1, and HD1 whereas no significant deviation from neutrality was detected in the other genes, suggesting a neutral evolution. Based on the results of GLM association analysis, 34 polymorphic sites in 6 genes were significantly related with the 4 panicle related-traits. This work was supported by a grant from the Next-Generation BioGreen 21 Program (Plant Molecular Breeding Center No. PJ011024012015), Rural Development Administration, Republic of Korea. *Corresponding Author: Tel. 02-880-4551, E-mail: heejkoh@snu.ac.kr -22-
OB-03 Genetic mapping of quantitative trait loci controlling seed weight in an interspecific soybean recombinant inbred line population Krishnanand P Kulkarni, Minsu Kim, Jeong Hwa Kim, Sovetgul Asekova, Jong Tae Song, Jeong-Dong Lee * School of Applied Biosciences, Kyungpook National University, Daegu 702-701, Republic of Korea Seed weight (SW), often expressed as 100-seed weight (HSW), is an important yield component in soybean and has been found to show positive correlation with seed yield. It is shown to behave as a quantitative trait controlled by many loci that are largely unclear. In this study, we represent the identification of chromosomal regions controlling the seed weight in soybean. We used a Recombinant Inbred Line (RIL) population, consisting of 188 lines derived from a cross of a wild soybean PI483463 (HSW: 0.85g) and a cultivated soybean cultivar Hutcheson (HSW: 14.05g) to identify the chromosomal regions controlling the SW trait. The population, along with parental samples and check, William82 (HSW: 21.2g) was grown for four years and phenotype data was recorded postharvest. A total of 535 SNP and 16 SSR markers, polymorphic between the parents were employed to genotype the RILs using Golden gate assay to develop the linkage map. Whole genome QTL scanning identified a total of 17 QTLs, spanning 10 chromosomes for the 100-seed weight. All these QTLs explained phenotypic variation (PV) in the range of 3.77 to 12.33%. Of the 17 QTLs, 2 QTLs qswa1-1 and qswd2-1, found to be the consistent QTLs, expressing in all the four environments. The QTL qswd2-1 explained highest contribution to the total PV with 10.04-12.23 %. The remaining 15 QTLs were identified in at least one environment with PV ranging up to 10.39%. The findings from this study will provide useful information to understand the genetic and molecular basis of SW and facilitate further genomic research leading to the yield improvements in soybean. -23-
OB-04 Rice PCR1 affects grain weight and zinc accumulation Hyun-Sook Lee 1, Won-Yong Song 2, Sang-Nag Ahn 1 1 College of Agriculture and Life Sciences, Chungnam National University, Daejeon, Korea 2 POSTECH-UZH Cooperative Laboratory, Department of Integrative Bioscience and Biotechnology, Pohang University of Science and Technology, Pohang, Korea Plants strictly regulate the uptake and distribution of Zinc (Zn), which is essential for growth and development. Arabidopsis thaliana plant cadmium resistance 2 (AtPCR2), a protein containing a placenta-specific 8 domain (PLAC8), is specifically expressed in the vascular tissue and epidermis of roots and is thought to act as a Zn efflux transporter (Song et al. 2010). Proteins containing PLAC8 domain function as major organ size regulators in Solanum lycopersicum and Zea may, and putative metal ion transporters in Arabidopsis thaliana, Oryza sativa and Brassica juncea. But, there are no reports which showed that the protein containing PALC8 have the function both of seed size regulation and metal homeostasis. In our study, we found that plant cadmium resistance 1 (PCR1) influences on both Zn accumulation and grain weight in rice. The expression of OsPCR1 is elevated in developing seeds of introgression line for GW2, which encodes a protein known to regulate grain weight. Grain weight of OsPCR1 knockout and knockdown lines decreased than the wild type, while OsPCR1 overexpression lines produced heavier grains. Furthermore, the grains of OsPCR1 knockdown lines exhibited substantially higher Zn and lower Cd concentrations than the control. We identified some variation in the OsPCR1 amino acid sequence between the japonica and indica rice types using 15 different rice varieties. Japonica-type PCR1 had a shorter N-terminus than did PCR1 in the other rice types. Furthermore, japonica-type grains accumulated less Zn than did indica-type grains. Our study suggests that rice PCR1 maintains metal ion homeostasis and grain weight and might have been selected for during domestication. *Corresponding Author: Tel. 042-821-7038, E-mail: ahnsn@cnu.ac.kr -24-

Exposure to ionizing radiation is regarded as a kind of abiotic stresses that can change the expression of genes in living organisms. This study aimed on investigating the variations in gene expressions induced by two different types of irradiations with different doses, which were low linear energy transfer (LET) gamma rays (100, 200, and 400 Gy) and high LET ion-beams (20, 40, and 80 Gy) on rice. RNA sequencing was carried out using the Illumina HiSeq-2500 platform. The average amount of reads were 4.8 Gb per individual, and 5 to 8% of the reads were removed after quality control. More than 90% of the RNA-seq reads were mapped to the rice reference genome sequence (IRGSP-1.0). A total of 247 differentially expressed genes (DEGs) were identified by comparison of the gene expression levels between the wildtype and the irradiated individuals. The 247 DEGs were divided into five modules and 27 intra-modular hub genes were found using the weighted correlation network analysis (WGCNA) method. The MEturquiose module had the most number of genes with 75 related to carbohydrate and small molecule metabolic processes. The co-expression network reconstructed using ARACNE (algorithm for reconstruction of accurate cellular networks) showed specific up- or down-regulation of the genes in each module according to the types and doses of radiation. This study will contribute to understanding the gene expression responses to ionizing irradiation. *Corresponding Author: Tel. 063-570-3311, E-mail: bioplant@kaeri.re.kr -27-

Therefore, it is important to identify resistance gene for CR disease and apply it to breeding of Brassica crops. In this study, we applied genotyping-by-sequencing (GBS) technique to construct high resolution genetic map and mapping of clubroot resistance (CR) genes. A total of 18,187 GBS markers were identified between two parent lines resistant and susceptible to the disease, of which 4,103 markers were genotyped in all 78 F 2 plants generated from crossing of both parent lines. The markers were clustered into nine linkage groups spanning 879.9 cm, generating high resolution genetic map enough to refine reported reference genome of cabbage. In addition, through QTL analysis using 78 F 2:3 progenies and mapping based on the genetic map, two and single major QTLs were identified for resistance of race 2 and race 9 of P. brassicae, respectively. These QTLs did not show collinearity with CR loci found in Chinese cabbage (Brassica rapa) but roughly overlapped with CR loci identified in cabbage for resistance to race 4. Taken together, genetic map and QTLs obtained in this study will provide valuable information to improve reference genome and clubroot resistance in cabbage. *Corresponding Author: Tel. 02-880-4547, E-mail: tjyang@snu.ac.kr -28-

The foxglove aphid resistance gene, Raso2 was previously mapped from PI 366121 (Glycine soja Sieb. and Zucc.) to a 26cM marker interval on soybean chromosome 7. The development of additional genetic markers, which are mapped closer to Raso2 were required to accurately position the gene to improve the effectiveness of marker assisted selection. The objective of this study was to narrow down the putative QTL region, which is responsible to foxglove aphid resistance in PI366121 using recently developed high-density 180K Axiom SoyaSNP genotyping array. One hundred and forty one F 8 -derived F 12 recombinant inbred lines developed from a cross of susceptible Williams 82 and resistant PI 366121, were used to generate a fine map of Raso2 interval. The phenotyping of antibiosis and antixenosis was done through choice and no-choice assays with total plant damage (TPD) and primary infestation leaf damage (PLD). The composite interval mapping analysis showed that the physical interval between two flanking makers, which was corresponding to Raso2, was narrowed down to 500kb on the Williams 82 genome assembly (Glyma2.0), instead of 4Mb in the previous report using Goldengate assay. In the Raso2 interval, there are about 60 candidate genes, including 4 of NBS-containing putative R genes. This result could be useful in breeding for new foxglove aphid resistant soybean cultivars. *Corresponding Author: Tel. 041-550-3621, E-mail: kangst@dankook.ac.kr -29-
OC-03 Characterization and genetic mapping of a abaxially rolled leaf mutant in rice. Hyerim Lee, Yoye Yu, Hee-Jong Koh * Department of Plant Science, Research Institute of Agriculture and Life Science, and Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-921, Korea. Leaves are the organ for photosynthesis, respiration and transpiration, and have a major effect on crop yield. Therefore, leaf shape and structure are important agronomic traits in breeding for ideal type plant. We obtained a new abaxially rolled leaf mutant from Ilpum(Oryza sativa ssp. japonica) by the treatment of ethyl methane sulfonate(ems). The abaxially rolled leaf mutant showed reduced plant height and panicle length, increased tiller number and panicle number than Ilpum. LRI(Leaf rolling index) analysis showed that the mutant have high value compared to the wild-type. In cross section analysis, the mutant was observed to have increased of bulliform cell number and size, and led to the outcurved leaf rolling. The phenotypes of the F1 plants derived from the cross between the mutant and Ilpum were normal. In F2 population, segregation ratio between the wild type and the mutant was 3:1. This genetic analysis indicated that leaf rolling is controlled by single recessive gene. Bulked segregant analysis(bsa) and genetic mapping were conducted using F2 population derived from the cross between mutant and Milyang23(Oryza sativa ssp. indica). According to the results, the gene was located on the long arm of chromosome2. Fine mapping is in progress.

Here, we investigated whether sound treatment could delay tomato fruit ripening. We treated harvested tomato fruits with low-frequency sound waves (1 khz) for 6 h, and then monitored various characteristics of the fruits over 14-day period at 23±1 C. Seven days after the treatment, 85% of the treated fruits were green, versus fewer than 50% of the non-treated fruits. Most of the tomato fruits had switched to the red ripening stage by 14 days after treatment. Ethylene production and respiration rate were lower in the treated than non-treated tomatoes. Furthermore, changes in surface color and flesh firmness were delayed in the treated fruits. To investigate how sound wave treatment affects fruit ripening, we analyzed the expression of ethylene-related genes by quantitative real-time RT-PCR analysis. We found that the expression level of several ethylene biosynthetic and ethylene signaling pathway-related genes was influenced by sound wave treatment. These results demonstrate that sound wave treatment delays tomato fruit ripening by altering the expression of important genes in the ethylene biosynthesis and ethylene signaling pathways. *Corresponding Author: Tel. 063-238-4617, E-mail: center1097@korea.kr -31-

OC-06 Expression analysis of two rice pollen-specific promoters using homologous and heterologous systems Tien Dung Nguyen 1, Moe Moe Oo 1, Sunok Moon 3, Hyun-Kyung Bae 1, Sung Aeong Oh 1, Moon-Soo Soh 2, Jong Tae Song 1, Jeong Hoe Kim 4, Ki Hong Jung 3, Soon Ki Park 1* 1 School of Applied Biosciences, Kyungpook National University, Korea. 2 Department of Molecular Biology, Sejong University, Korea. 3 Graduate School of Biotechnology & Crop Biotech Institute, Kyung Hee University, Korea. 4 Department of Biology, Kyungpook National University, Korea. Tissue-specific promoters are a very useful tool for manipulating gene expression in a target tissue or organ; however, their range of applications in other plant species has not been determined, to date. In this study, we identified two late pollen-specific rice promoters (ProOsLPS10 and ProOsLPS11) via meta-anatomical expression analysis. We then investigated the expression of both promoters in transgenic rice (a homologous system) and Arabidopsis (a heterologous system) using ProOsLPS10 or ProOsLPS11::GFP-GUS constructs. As predicted by microarray data, both promoters triggered strong GUS expression during the late stages of pollen development in rice, with no GUS signals detected in the examined microspores and sporophytic tissues. Interestingly, these promoters exhibited different GUS expression patterns in Arabidopsis. While in Arabidopsis, the OsLPS10 promoter conferred GUS expression at the uni- and bi-cellular macrospore stages, as well as at the shoot apical region during the seedling stage, the OsLPS11 promoter was not active in the pollen at any stage, or in the examined sporophytic tissues. Furthermore, by performing a complementation analysis using a sidecar pollen (scp) mutant that displays developmental defects at the microspore stage, we found evidence that OsLPS10, which can be an applied promoter expressed in Arabidopsis, is useful for directing gene expression in the early stages of pollen development. Our results indicate that the OsLPS10 and OsLPS11 promoters can drive the expression of target genes during the late stages of pollen development in rice, but not in Arabidopsis. Our results also emphasize the necessity of confirming the applicability of an established promoter to heterologous systems. *Corresponding Author: Tel. 053-950-7751, E-mail: psk@knu.ac.kr -33-

Since maintaining and screening such massive resources remain as a great challenge, it is important to establish piratical ways to manage them. A core collection, by definition, refers to a subset of entire population but preserves most of the possible genetic diversity, enhancing the efficiency for germplasm utilizations. Here we reports the whole genome resequencing of the 137 Korean rice core set (KRICE_CORE) that represents 25,604 rice germplasms deposited in Korean genebank of Rural Development Administration (RDA). We implemented the Illumna HiSeq 2000 and 2500 platform to produce short reads and then assembled those with 9.8x depth using Nipponbare as a reference. Comparisons of the sequences with the reference genome yield more than 15 million(m) single nucleotide polymorphisms (SNPs) and 1.3M insertion/deletion (INDELs). Phylogenetic and population analyses using 2,046,529 high quality SNPs successfully assigned each rice accessions to the relevant subgroups, suggesting those SNPs comprehensively capture evolutionary signatures accumulated in rice subpopulations. Furthermore, genome-wide association studies (GWAS) for 4 exemplary agronomic traits from the KRIC_CORE manifest the utility of KRICE_CORE, identifying previously defined gene or novel genetic polymorphisms that potentially regulate the important phenotypes. This study provides strong evidences that the size of KRICE_CORE is small but contains such a high genetic and functional diversity across the genome. Thus those resequencing results will be useful for future breeding, functional and evolutionary studies in the post-genomic era. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr -34-

PA-03 QTL analysis for drought tolerance using introgression lines from a cross between Milyang 23 and O. glaberrima Ju-Won Kang 1, Dong-Min Kim 2, Hyun-Sook Lee 1, Yeo-Tae Yoon 3, Sang-Nag Ahn 1* 1 Department of Agronomy, Chungnam National University, Daejeon 305-333, Korea 2 Department of Variety Testing, Korea Seed & Variety Service, Gimcheon 740-220, Korea 3 Chungnam Agricultural Research and Extension Services, Yesan 340-861, Korea Drought stress is one of the major stresses affecting growth and productivity in rice. Drought tolerance is a complex trait governed by quantitative trait loci(qtls) making it difficult to understand mechanisms underlying it. We generated a set of 55 introgression lines via backcrosses using Milyang23, the Korean Tongil-type rice variety as the recurrent parent and Oryza glaberrima (IRGC Acc. No. 103544) as a donor parent. 139 SSR markers were used to genotype 55 introgression lines. The 55 introgression lines with Milyang23 were evaluated for physiological traits such as fresh shoot weight (FSW), fresh root weight (FRW) and dry shoot weight (DSW) under the control and 30% PEG-treated condition. Three lines (IL9, IL12, and IL55) showing significant difference with Milyang23 were selected for further analysis. Genotyping revealed that three lines had four, four and two O. glaberrima homozygous segments, respectively. IL9 performed better than Milyang23 in all traits measured in the 30% PEG-treated condition. IL9 possessed four O. glaberrima introgressions on chromosomes 1, 2, 6 and 7. IL12 performed better than Milyang23 in FSW and FRW and contains four O. glaberrima introgressions on chromosomes 3 and 6. IL55 contains two O. glaberrima introgressions on chromosomes 2 and 6. Three lines shared the O. glaberrima segment delimited by markers RM133-RM225 at chromosomes 6. This region corresponds to the QTL region for drought tolerance reported by other previous studies. Although IL9 and IL12 showed improved drought tolerance at the seedling and vegetative stage, they performed poor under the drought stress at the reproductive stage implying that the level of drought tolerance differs according to the growth stage in rice. IL55 was not significantly different from Milyang 23 in SPP and FER and had significantly higher no. of the total grain than Milyang 23. This result seems to indicate that IL55 will be a good resource for drought tolerance breeding. The population would be useful not only in developing drought tolerant lines in the breeding program but also in fine-mapping the genes/qtls for drought tolerance. *Corresponding Author: Tel. 042-821-7038, E-mail: ahnsn@cnu.ac.kr -39-

PA-12 Distinct reactions of two Tunisian durum wheat to salinity stress Sang Heon Kim 1, Inès Yacoubi 2, Yong Weon Seo 1* 1 Department of Biosystems and Biotechnology, Korea University, Seoul 136-713. Republic of Korea 2 Centre de biotechnologie de Sfax (CBS), Sfax, Tunisia Durum wheat (Triticum turgidum L. ssp. durum) is a global staple food crops. However, saline soil reduces the production of durum wheat in a lot of countries including Tunisia. This problem would be more severe as soil salinization ascribed by the global climate changes and worldwide water deficiencies. To overcome this circumstance, we performed two experiments related to salinity stress tolerance of durum wheat. Two Tunisian durum wheat cultivars ( Om Rabia, Mahmoudi ) were applied to examine the reaction to salt stress. At the third leaf stage, salt stress was treated by submerging the pots into 500 mm NaCl for 5 mins everyday instead of irrigation in greenhouse. The treatment was applied for 1 week and their tolerances to salt stress were determined by comparing their growth parameters to the control plants. Total RNA was extracted and Quantitative reverse transcript PCR (qrt-pcr) using the genes linked with the salt tolerance was performed. The plant height and leaf chlorophyll content were reduced during salt stress treatment in both cultivars. The growth parameters of Om Rabia was reduced less than that of Mahmoudi. The transcription level of the genes linked with the salt tolerance was greater in Om Rabia than in Mahmoudi. These results will be fruitful to future breeding program for salt tolerant tetraploid durum wheat.

PA-25 Influence of haplotype combinations of genes involved in regulation of rice grain size and development of a regression equation model Jonghwa Park, Chan-mi Lee, Backki Kim, Hee-Jong Koh * Department of Plant Science, Plant Genomics and Breeding Institute, Research Institute for Agriculture and Life Sciences, Seoul National University, Seoul, Korea The world population has been continuously increasing and has led to the growing demand for rice. It is therefore important to pay as much attention to the enhancement of grain yield as well as grain quality. Grain size is one of the major factors determining grain yield and quality. A large number of genes are known to be involved in regulation of grain size. However, the influence of their haplotype combination is still largely unknown. Of the previously characterized genes, we especially focused on the six genes (GS3, GS5, GS6, GW2, qsw5/gw5, and GW8/OsSPL16) to expand our understanding of regulation of grain size and to develop a regression equation model that can be used for molecular rice breeding. A total of 215 rice germplasms, which originated or developed from 28 rice-consuming countries, were used in this study. The genotyping analysis revealed that different alleles of the six genes were widely distributed in our germplasm collection and also showed significant associations with the differences in grain size. Interestingly, we found that the relatively small number of haplotype combinations preserved in diverse rice germplasms and showed significant associations with the differences in grain size. In addition, we also found that a single gene-specific allelic variation plays an important role in regulation of grain size in the presence of a certain type of haplotype combination. Based on these results, we developed a regression equation model for prediction of rice grain size. We expect that our model can be used for rice molecular breeding to develop new rice varieties having a grain size in a particular range.

Francis 2 1 Sejong University, Dept. of Bioresources Engineering, Seoul, 143-747, Korea 2 The Ohio State University, Ohio Agricultural Research and Development Center, Dept. of Horticulture and Crop Science, Wooster, OH 44691, USA Bacterial spot of tomato is a disease complex caused by at least four species of Xanthomonas and leads to severe yield and quality losses in humid growing conditions in the world. Five physiological species (T1-T5) have been defined by their virulence on tomato varieties. These races are associated with three species: X. euvesicatoria (T1), X. vesicatoria (T2), and X. perforans (T3-T5). Recent epidemics of X. gardneri has occurred in the Midwest United States. In this study, we developed germplasm with resistance to multiple species of bacterial spot. Six advanced breeding lines with at least three different source of resistance were crossed and their F1 hybrids were inter-mated to produce a complex breeding population consisting over 1,100 progeny. Three lines (OH7663, OH7667 and 2k7-6117-S2) were selected by field evaluations of the population against T1, T2, T3, and X. gardneri. Graphical genotypes demonstrated that these breeding lines contain a QTL and Rx-4/Xv3 in coupling phase on chromosome 11 as well as Rx-3 on chromosome 5. In order to test the combining ability of the lines, we developed hybrids from multiple crosses and conducted replicated field trials to evaluate bacterial spot resistance and yield. As a male parent, OH7663 showed acceptable combining ability for yield and for resistance against multiple species of Xanthomonas. Several hybrids produced yields that were not significantly different from yields of commercial varieties. -57-

Root is the primary tissues exposed to water limitation in soil. Although a number of transcriptome data under water limitation have been produced in rice, but most of them have analyzed the effect of leaf or shoot. Thus, understanding of relating molecular mechanism is still limited. To get global view of the effect on water deficiency in rice root, we carried out RNA-Seq experiment. To do this, we compared the RNA-Seq transcriptome data of 3 day samples under water deficiency with those of unstressed rice roots with unstressed control. As a result, we identified 1,098 genes upregulated in water stress condition for 3 days. Gene ontology (GO) enrichment analysis revealed that 18 GO terms are overrepresented. Of them, valyl-trna aminoacylation, transcription from RNA polymerase II promoter, glycine catabolic process, and L-phenylalanine catabolic process are more significant, indicating that transcription of new transcripts, control of translation fidelity, and reuse of primary and secondary metabolites can be activated during water stress. *Corresponding Author: E-mail: khjung2010@khu.ac.kr -60-

Results indicated that one major QTL (qdth6) on chromosome 6 was associated with significant variation for days to heading. 83 lines without the O. rufipogon segment at qdth6 were selected and analyzed for grain quality traits. QTL analysis was conducted for two groups, 96 and 83 introgression lines, and a total of 25 QTLs were detected for rice quality traits. 16 QTLs were detected in a group of 93 lines, 11 QTLs detected in a group of 83 lines, and 2 QTLs were commonly identified in both groups. Most of the QTLs detected in this study were located on the same or adjacent regions as those reported by the previous studies, and the wild alleles negatively affected quality traits. In contrast, the wild allele at qgcr9 for the glossiness of cooked rice on chromosome 9 contributed to an increase in glossiness which is positively correlated with rice eating quality. Three ILs with the wild allele at qgcr9 displayed better eating quality than the recurrent parent, Hwaseong. To confirm the effect of qgcr9, high density mapping of the qgcr9 with a series of NILs will be conducted. *Corresponding Author: Tel. 042-821-5728, E-mail: ahnsn@cnu.ac.kr PA-40 The development of physiological phenotyping parameter to characterize early stress responses in rice plants Hye-Jin Yoon 1*, Kyung Hwan Kim 1, Yeon-Hee Lee 1, Eun-Jung Suh 1, Taek-Ryun Kwon 2 1 Molecular Breeding Division, Department of Agricultural Biotechnology, National Academy of Agricultural Science, RDA, 560-500, KOREA 2 Biosafety Division, Department of Agricultural Biotechnology, National Academy of Agricultural Science, RDA, 560-500, KOREA Research on salinity stress has strongly increased over the last decade, as salinity stress is a main key factor limiting the global crop production in many regions of the world. In recent years, it is possible to obtain a large amount of genotypic data in a short time due to a reduction in genotyping costs. This wave of genomic information has effected the development of new strategies for the integration of molecular information in breeding programs. However, phenotyping is still a manual activity, and different from each species, environment, and trait. It often generates high labor costs, and can be sensitive to environmental changes, and sometimes includes the individual biased assessments from different people. There is a strong demand for phenotypic data of high quality. The current objective of phenomics is phenotyping a large number of individuals for many traits in a nondestructive manner and with good accuracy. Here we described the image-based technology as applied to alleviate the bottleneck for the development of high-throughput phenotyping platforms. Several trials to measure stress responses of rice plantlets based on image data under the salinity condition are underway to develop automation for the next-level of phenotyping. *Corresponding Author: Tel: 063-238-4659, E-mail: hyejinyoon@korea.kr -61-

Gynoecy plays an important role in cucumber hybrid breeding and use of gynoecious lines as maternal parent ensures high productivity. The purpose of this study is to identify a co-dominant molecular marker linked to F locus to distinguish homozygous and heterozygous gynoecious plants for cucumber breeding programme. Firstly, we analyzed the sequence polymorphism of 5 gynoecious and 5 monoecious inbred lines to detect polymorphism to develop the marker linked to F locus. A pair of specific primer based on insertion/deletion polymorphism on branched-chain amino acid transaminase (BCAT) gene was designed and examined the polymorphism in the parents, F 1 and F 2 segregating population derived from gynoecious (WJEF11) and monoecious (WNEF8) inbred lines. The result showed that the specific fragment amplified with Cs-Female-F/Cs-Female-R, was identified as a co-dominant marker and co-segregated with sex phenotype in F 2 population. Furthermore, we present a new linkage map for F locus using Indel markers. This is the first report for the development of F locus specific co-dominant marker which can distinguish homozygous and heterozygous gynoecious and it could be used in marker-assisted selection in cucumber breeding. *Corresponding Author: Tel. 02-3408-4376, E-mail: sanglee@sejong.ac.kr -62-

Shannon: Division of Plant Sciences, University of Missouri- Delta Center, Portageville, MO 63873, USA Shoot-fresh-weight (SFW) is one of the parameters, used to estimate the total plant biomass yield in soybean. Understanding the genetic and molecular basis of SFW could help increase the total biomass production. In this particular study, we identified QTLs associated with SFW in a Recombinant Inbred Line (RIL) population derived from interspecific cross of PI483463 and Hutcheson. A total of 551 (535 SNP and 16 SSR) markers, were found to be polymorphic between the parental lines and were used to screen the RILs to develop the genetic map. Linkage analysis and QTL mapping were performed using with the software QTL IciMapping version 4.0, with the minimum LOD score of 3.0 and estimating the likelihood of a QTL and its corresponding effects at every 1cM. QTLs with LOD value > threshold LOD, as determined by 1000 permutation tests at p > 0.05 were considered as significant QTLs. The analysis identified a total of 5 QTLs associated with shoot fresh weight over two environments, with the phenotypic variation (PV) ranging from 6.34 to 21.32%, and the additive effect from -0.54 to 0.33. Among these QTLs, qfw1314_19_1 had the largest LOD scores, with PV of 21.32%. Interestingly, three QTLs, qfw2013_19_1, qfw2014_19_1, and qfw1314_19_1 identified on chromosome 19(L), showed negative additive effects, indicating the contribution from the wild parent PI483463. The QTLs identified in this study can be the targets to identify the candidate genes for the SFW and can help in developing cultivars with increased biomass potential. *Corresponding Author: Tel. 053-950-5709, E-mail: jdlee@knu.ac.kr PA-46 옥수수유망자식계통들에대한잡종강세및수량관련형질의유전분석 박종열 1, 박기진 1, 사규진 2, 이주경 2* 1 강원도농업기술원옥수수연구소 2 강원대학교농업생명과학대학식물자원응용공학과 본연구는종실수량과 SSR 마커사이의상관분석을위하여종실용옥수수 9 개의자식계통을이용하여반이면교잡 (Half-Diallel Cross) 을통해얻어진 36 개의 F 1 교잡종들에대하여수량과농업형질그리고유전적거리와의상관을분석하였다. 그결과, 농업형질에의한유연관계분석에서가장가까운계통은 Wf9 와 ND203 으로 0.809 를보였고, BSSS (Iowa Stiff Stalk Synthetic) 그룹인 B73 과 B14A 가 0.810 으로가까운것으로나타났다. 그러나같은 LSC (Lancaster Sure Crop) 그룹인 Va85 와 C103 은가장거리가먼것으로나타나서농업형질로유전적거리를측정하는것은한계가있는것으로보였다. 따라서본연구에서는 92 개의 SSR primer 들을가지고 step-by-step 방식으로옥수수종실수량에영향을미치는분자마커를선발하고자하였다. 선발된 9 개의 SSR primer 들을이용하여옥수수종실중과의상관분석을수행한결과, 고도의정의상관 (R2=0.703**) 을보였다. 선발된 SSR 마커를이용한유전적거리와교잡종의주요농업형질의상관분석에서종실중, 이삭장, 이삭경등수량관련형질뿐만아니라간장, 착수고도유의성을보였다. * 주저자 : Tel. 033-250-6415, E-mail: jukyonglee@kangwon.ac.kr -64-

The objective of this study was to identify the putative QTL for foxglove aphid resistance in wild soybean, PI 366121, (Glycine soja Sieb. and Zucc.). One hundred and forty one F 2 -derived F 8 recombinant inbred lines developed from a cross of susceptible Williams 82 and resistant PI 366121, were used. The phenotyping of antibiosis and antixenosis was done through choice and no-choice assays with total plant damage (TPD) and primary infestation leaf damage (PLD); a genome-wide molecular linkage map was constructed with 504 single nucleotide polymorphism markers utilizing a GoldenGate assay. Using inclusive composite interval mapping analysis for foxglove aphid resistance, one major candidate QTL on chromosome 7 and 3 minor QTL regions on chromosome 3, 6 and 18 were identified. The major QTL on chromosome 7 showed both antixenosis and antibiosis resistance responses. However, the minor QTLs showed only antixenosis resistance response. The major QTL mapped to a different chromosome than the previously identified foxglove aphid resistance QTL, Raso1, from the cultivar Adams. Also, the responses to the Korea biotype foxglove aphid were different for Raso1, and the gene from PI 366121 against the Korea biotype foxglove aphid were different. Thus the foxglove aphid resistance gene from PI 366121 was determined to be an independent gene to Raso1 and designated to Raso2. This result could be useful in breeding for new foxglove aphid resistant soybean cultivars. *Corresponding Author: Tel. 041-550-3621, E-mail: kangst@dankook.ac.kr PA-48 Identification of quantitative trait loci related to grain filling under low temperature condition Jong-Min Jeong *, Ung-Jo Hyun, Ji-Ung Jeung, Kyung-Ho Kang, Young-Chan Cho, Bo-Kyeong Kim Crop breeding division, National institute of crop science(nics), Wan-ju 565-851, Republic of Korea Low temperature is a major abiotic stress that adversely affects rice production in rice cultivation regions of the world. Low temperature during the rice growing season, can inhibit growth and development at any development stage, from germination to grain filling. Among the rice growth stage, reproductive stage was known as the most sensitive to low temperature, causing sterile grain and lead yield loss. However, low temperature during the grain filling stage also, may cause delay and incomplete grain maturation. In this study QTL analysis were performed to identify the QTLs associated with percent of grain filling under low temperature condition during the grain filling stage. A 139 RIL derived from a cross between Milyang23 (Tong-il, cold susceptible) and Gihobyeo (Japonica, cold tolerance) were exposed to air and water of 17 at the same time for 14 days during the grain filling stage. One significant QTL associated to percent of grain filling was detected on chromosome 7. This QTL could explain 14.7% of the phenotypic variance for percent of grain filling. We have the plan to confirm the detected QTL through further study. *Corresponding Author: Tel. 063-238-5217, E-mail: jjm0820@korea.kr -65-

PA-51 Development of QTL-NIL to Blast Resistance Origined from Korean Weedy Rice Young-Chan Cho *, Man-Ki Baek, Jung-Pil Suh, Yong-Jae Won, Jong-Min Jeong, Hyun-Su Park, Jeong-Ju Kim, Jeong-Kwon Nam, Ki-Young Kim National Institute of Crop Science, Suwon 441-857, Korea Rice blast caused by the fungal pathogen, Magnaporthe oryzae, is a serious disease affecting yield loss and decreasing its quality in rice production. Rice breeders in Korea have developed many japonica varieties showing resistance to blast. However, the blast resistance in most japonica varieties has broken down within a few years after they were released to farmers because of the spread of new virulent races of M. oryzae. There is the most effectiveness to look for novel resistant gene(s) that can express the resistance to broad-spectrum races in diverse environmental conditions. We identified a major QTL, qlb4.1 linked tightly to RM6352 and RM3643 in 52.6 cm region on chromosome 4 related to the resistance for isolate inoculation and nursery test, and neck blast from a Korean weedy rice, Geumleungaengmi33. This QTL explained 26.1 28.6% and 45.3 53.1% of total phenotypic variation by the allele of GL33 for isolate inoculation and nursery test, respectively. A line SR30058(52)-1-1 (Suweon545) that containing the QTL qlb4.1 was developed from Ilpum*4/GL33 by marker-assisted backcross method. This line showed resistant reactions to blast nursery test across regions and years, and resistance to neck blast at the hot-spot field in Jecheon. Suweon545 showed also durable resistance of lower 10% of diseased leaf areas (DLAs) in sequential planting method. This line screened by graphical mapping using 136 SSR markers that evenly distributed on 12 chomosomes. Suweon545 contained GL33 alleles of donor parent in a total of 12 loci (8.8%) including QTL region on chromosome 4. In future, Suweon545 would be useful to develop the broad-spectrum resistance variety in japonica rice breeding program. *Corresponding Author: Tel. +82-63-238-5211, E-mail: yccho@korea.kr, -67-

CBL-interacting serine/threonine protein kinases (CIPKs) have been implicated to play important role in regulating various abiotic stresses such as cold, salinity and drought. In this study, to understand the function of this gene under pre-harvest sprouting in rice, a cdna clone encoding CBL-interacting protein kinase 15 was isolated from rice flowers. We constructed a recombinant vector carrying the CIPK15 under the control of the CaMV 35S promoter and Tnos terminator and transformed into rice using Agrobacterium tumefaciens. Insertion of the gene was verified in transformants using HPT resistance test and genomic PCR. Transcriptional profiling using tissues of wild type, Gopum, revealed expression of the gene in whole plant tissues with level of expression highest in the seeds suggesting possible role in dormancy. Comparative expression analysis of the gene in transgenic and wild type through semi-quantitative RT-PCR and real-time PCR showed higher expression in transgenic rice lines. Moreover, screening in the mist chamber showed overexpression lines that were resistant to the PHS. This result suggests the involvement of CIPK15 in the regulation of pre-harvest sprouting.

This class of protease has been implicated in various physiological aspects of developmental stages in plants including seed germination, senescence, and disease immunity. A handful of studies assigned plants cysteine protease in different molecular battlefield under a few selected pathosystems, and initially extricated complex molecular mechanism of resistance. However, its potential use as an agent of resistance to diseases in rice has never been explored. This study demonstrates the function of CP specifically in rice - Xanthomonas oryzae pv. oryzae (Xoo) pathosystem. The CP -encoding full-length cdna was cloned from Brassica rapa and transformed into japonica rice cv. Gopumbyeo. The gene was overexpressed under the control of CaMV35S promoter in pflc vector. Blast analysis of the conserved domain of the gene confirmed its affinity to Peptidase_CIA family. RT-PCR analysis showed that the gene was constitutively expressed in all tissues tested. Regulation of rice resistance through cysteine protease activity is evident in overexpression lines which exhibited an enhanced resistance to four Korean Xoo isolates. Further analyses will be carried out to uncover the specific role of CP in rice-xoo interaction.

PA-60 Association of haplotype variations in GmCHX1 with salt tolerance in wild and cultivated soybeans. Jeong Hwa Kim, Jong-Tae Song, Jeong-Dong Lee * School of Applied Bioscience, Kyungpook National University, Daegu 702-701, Republic of Korea Soybean [Glycine max (L.) Merr.] is a major agricultural crop widely used for providing human and animal food owing to its high protein and oil content. For this reason, they have been consumed in Asia and world greatly and demand is ever increasing. Soybean is classified as a moderately salt-sensitive crop and its production is greatly affected due to increasing salinity stress. About 8 % of the world s total land is salt-affected. In Korea, around 9 % of total agricultural land (approximately 130,000ha) was reclaimed since 1960's. In order to meet the demand for soybean and to solve arable land shortage problem, it is unavoidable to cultivate soybean in salt-affected soils. Fortunately, soybean germplasm has been shown to have salt-tolerant phenotypes, which have been used to identify the salt-tolerant genes. GmCHX1, a novel ion transporter, is one of the genes known to confer salt tolerance in soybeans. Present study was conducted to understand the effects of sequence variations of GmCHX1, on salt tolerance in wild and cultivated soybeans. A total of 1026 (301 lines of G. max and 725 lines of G. soja) lines were phenotyped for salt tolerance in greenhouse conditions. At the V1-V2 growth stage, the plants were treated with 100mM NaCl solution for two weeks and thereafter the response was measured depending on leaf scorch score (1-health, 3-mid, 5-dead). About 20 lines found to show tolerance to saline conditions and were selected for sequence analysis of GmCHX1. Most of the haplotypes detected in this study corresponded with the haplotype patterns in previous studies. However, several lines showed different patterns of polymorphism in the coding region, suggesting that sequencing of more lines and analysis for the polymorphism in GmCHX1 is needed in order to identify new haplotypes that could confer greater salt tolerance. *Corresponding Author: Tel. 053-950-5709, E-mail: jdlee@knu.ac.kr -73-

To define whole genome-level of structural variation by ionization energies and radiation doses in plant, the seeds of Ilpum rice cultivar were acutely irradiated with gamma rays (100Gy, 200Gy, and 400Gy) and ion-beams (20Gy, 40Gy, and 80Gy), respectively. Six M 1 rice plants were re-sequenced by Hi-Seq2500 with Ilpum cultivar as control. The average sequencing coverage of the individuals was 10.6X, and the average mapping rate to the rice reference genome (IRGSP-1.0) sequence was 96.95%. The individual plants were irradiated with gamma-400gy and ion-50gy had highest variation of SNP with 471,837 and 469,147, respectively. The number of insertion/deletion was 77,500 and 77,106, the synonymous and frame-shift were 7,859 and 7,763 in above two individuals. Although high genome variation shown between Ilpum cultivar and irradiated individuals, there were non-correlation between number of variation and radiation doses. However, five individuals, except ion-20gy, showed 33 common variant blocks (CVBs) spanning 6 Mb in whole rice genome (1.6%). The CVBs were distributed on 12 rice chromosomes, Chromosome 6 had biggest CVB (5 blocks, 1.3Mb), whereas chromosome 9 had smallest CVB (0.01Mb). Total five hundred fifty one genes were in CVBs which can regard radiation sensitive genes or may be regarded as radiation hot spots in rice genome.

PB-08 Genetic Diversity of Rice Landraces Collected in Cordillera Region, Philippines Backki Kim, Sheryl N. Sierra, Hong-Yeol Kim, Hee-Jong Koh * Department of Plant Science, Research Institute for Agriculture and Life Sciences, and Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-921, Republic of Korea Banaue Rice Terraces in the Philippines has been a rich source of genetic diversity of untapped rice landraces in the mountainous region of Cordillera. Although some may have been included into modern breeding programs, significant indica-japonica differentiation among landraces cultivated in the region is not well known. Thus, Cordillera landraces differentiation across different altitude gradient (458 m to 1830 m) will provide great opportunities for improvement on rice genetics. We analyzed the genetic variation among 166 accessions collected in 17 towns in 6 provinces across different altitudes using Subspecies Specific Sequence Tagged Site (SS-STS) and Insertion-Deletion (InDel) markers. Subspecies Prototype Index (SPI) degree of each landrace was used to calculate the genomic inclination of each variety towards subspecies. The 50 molecular markers (24 SS-STS and 26 InDel) that assayed variation in 166 accessions revealed 116 alleles. Gene diversity ranged from 0.04 (R3M23) to 0.50 (S04058) with an average of 0.40. Polymorphism information content (PIC) ranged from 0.04 (R3M23) to 0.37 (S12030, S07047, R10M40, S10001, S04058 and S09040B) with an average of 0.31. Using the control varieties to assign groups, the larger group of 114 Cordillera landraces corresponds to 71% japonica type while the smaller group of 42 corresponds to 26% indica and 3% intermediates. A total of 7 (4%) indica and 9 (6%) japonica type accessions were found above 1500 m. Results of this study suggested that majority of japonica type rice landraces were grown in high altitudes of Banaue Rice Terraces and nearby provinces, and interestingly, indica type rice landraces were cultivated in areas at much higher altitudes (>1500 m) than those categorized by the traditional methods.

PB-09 Differentially expressed proteins between two Korean inbred lines under drought stress at vegetative stage Sang Gon Kim *, Seonghyu Shin, Hwan Hee Bae, Jin-Seok Lee, Jung-Tae Kim, Min Jung Seo, Beom-Young Son, Jeom Ho Lee, Seong-Bum Baek Department of Central Area Crop Science, National Institute of Crop Science, Rural Development Administration, Suwon 441-707, South Korea Understanding the response of a crop to water deficiency is the first step towards breeding drought-tolerant varieties. In this study, inbred maize (Zea mays L.) lines KS140 and KS141 were subjected to drought stress by withholding water for 10 days at the V5 or V6 leaf stage. Water-deficient plants experienced a decrease in relative leaf water content, stomatal conductance, net CO 2 assimilation rate, and water use efficiency compared to well-watered plants. This was accompanied by a decrease in the relative leaf water content that resulted in severe growth retardation in KS140 and KS141. However, leaf chlorophyll content in KS140 was unchanged. To understand the proteome dynamics during the 10-day drought stress in maize leaves, comparative proteome analysis was carried out between the well-watered and water-withheld leaves. Differential expression was observed for 29 protein spots from KS140 and 14 protein spots from KS141, and these were identified using MALDI-TOF mass spectrometry. Among identified proteins, metabolism and stress related proteins were highly were increased by drought stress. This study provides a protein profile of a Korean maize inbred line during drought stress, which will be valuable for future studies of the molecular mechanisms underlying drought resistance and for development of selective breeding markers for drought tolerance in maize. *Corresponding Author: Tel. 031-695-4045, E-mail: sen600@korea.kr PB-10 주성분분석및군집분석을이용한자생국화의휘발성향기성분분류 김수정 1*, 하태정 2, 김종윤 3, 유동림 1, 서종택 1, 김율호 1, 홍수영 1, 남정환 1, 손황배 1, 장동칠 1, 김기선 4 1 국립식량과학원고령지농업연구소 2 농촌진흥청연구정책과 3 배재대학교원예조경학부 4 서울대학교원예생명공학과 본연구는자생국화 15 분류군의휘발성향기성분을다변량분석을통해분류학적유연관계를구명하여그분류기준을제시하고조경용및약용소재로이용하기위한기초자료로활용하고자본연구를수행하였다. 국화속 15 분류군의잎을대상으로 GC/MS 분석결과, 총 45 종의휘발성향기성분이함유된것으로나타났으며, camphor, borneol, phytol, α-pinene, camphene, 1,8-cineole 및 germacrene-d 는모든분류군에공통적으로함유된것으로나타났다. 국화속 15 분류군은 hydrocarbon 류 (sabinene, cymene, β-selinene), alcohol 류 (1-octen-3-ol, cischrysanthenol,hinesol), ketone 류 (chrysanthenone, camphor), 및 ester 류 (cis-sabiene hydrate, trans-chrysanthenyl acetate) 의휘발성향기성분을바탕으로주성분분석과군집분석결과총 3 그룹으로분류할수있었다.

Salt and drought tolerance and adaptation in rice has been improved by engineering various genes related to transcription, signaling, accumulation of antioxidants and compatible solutes etc. Previously, we have produced 2,000 non-gm mutants induced by Tos17 in rice. We analyzed >2,000 flanking sequences of newly transposed Tos17 copies by the adaptor-ligation PCR method. We also identified significantly up- or down-regulated genes under drought, salt, or ABA stress in rice based on expression microarray data, which previously were performed from leaf at different developmental stages and conditions.

A rice retrotransposon, Tos17, is active during tissue culture and its ability was wildly used in insertional mutagenesis. In this study we have produced 2,000 non-gm mutants induced by Tos17 in rice. We analyzed >2,000 flanking sequences of newly transposed Tos17 copies by the adaptor-ligation PCR method. The frequencies of Tos17 insertions in the genic and intergenic regions were 60.3% and 36.6%, respectively. We also selected four Tos17 insertion mutant lines for three TF genes which can be considered to be considered to be involved in rice seed development based on expression microarray data: osrem3, osta1, osbhlh1-1, and osbhlh1-2 mutant lines. According to Quadruple 9-mer-based protein binding microarray (Q9-UPBM) experiment, we found that the OsREM3, OsTA1, and OsbHLH1 bound to the ACACCAC, CACGTG, and GTAACA motifs, respectively. In combination of Q9-UPBM, RiceArrayNet analysis, and expression microarray data, we identified 8, 20, and 9 putative target genes of OsREM3, OsTA1, and OsbHLH1, respectively. We have been screening and characterizing the mutations by extensive phenotypic analysis as well as the functional analysis of genes. *Corresponding Author: Tel. 031-330-6193, E-mail: bhnahm@gmail.com PB-14 Phenotypic screening and breeding with colored wheat by mutation breeding technique Jin-Baek Kim 1*, Min Jeong Hong 1, Young Ha Yoon 1, Dong Sub Kim 1, Soon-Jae Kwon 1, Hong Il Choi 1, Si-Yong Kang 1, Yong Weon Seo 2 1 Advanced Radiation Technology Institute, Korea Atomic Energy Research Institute, 29 Geumgu, Jeongeup, Jeonbuk 580-185, Korea 2 Korea University, Anam-dong Seongbuk-Gu, Seoul, 136-701 Korea Anthocyanin, a group of purple or reddish flavonoids, have been recognized as health-promoting functional food ingredients due to antioxidant activity.

Kenaf (Hibiscus cannabinus L.) native to Africa can be used as fiber, food, feedstock and bio plastic. This study was carried out to evaluate the mineral, amino acid and vitamin contents of six selected kenaf cultivars which are enable to produce seed under Korean circumstance. The leaves of three mutant cultivars (Jangdae, Jeokbong and Baekma), two original cultivars (Jinju, C14) and one Chinese cultivar (Auxu) were harvested at flowering time. Mineral components of kenaf leaves, such as calcium, potassium, and mineral, did not showed significant differences among the cultivars. As major amino acids including proline and phenylalanine, significant differences were found in these kenaf cultivars. The Auxu cultivar contained the highest amount of essential amino acid (Phenylalanine, Leucine, Isoleucine, Valine, Methionine and Lysine). The amount of vitamin displayed significant differences such as vitamin E and vitamin K among these cultivars. Especially, Jangdae cultivar contained the highest amount of vitamin E and vitamin K. Thus, these data suggested that Jangdae and Auxu is the most desirable cultivar containing high amount of vitamin and amino acid. *Corresponding Author: Tel. 063-570-3310, E-mail: sykang@kaeri.re.kr PB-18 Negative roles of MAPK signaling cascades for itrogen-fixing nodule formation in Medicago truncatula Wonsil Bae, Jinsoo Lee, Hojin Ryu * Department of Biology, Chungbuk National University, Cheongju, 361-763, Korea Mitogen-activated protein kinase (MAPK) signaling cascades play critical roles in various cellular events including abiotic/biotic stress responses, innate immunity, hormone signaling and cell specificity in plants. The MAPK-mediated stress and ethylene signaling are recently known to be involved in nitogen-fixing symbiotic interactions; however, the biological role of MAPK for nodule development in legume plants is largely unknown. We here elucidated that MtMKK5-MtMPK3/6 cascade negatively regulate the nitrogen fixing nodule formation in Medicago truncatula. MtMKK5, an ortholog of SIMKK, overexpression significantly reduces the nodule formation in M. truncatula roots. MtMKK5 directly activates MtMPK3/6 by phosphorylation on the TEY motif within the activation loop in the cytoplasm, which might link to EFD as a negative regulator for nodule formation. EFD has a putative MAPK phosphorylation Thr residue and could be a target of the activated MtMPK3/6 in the nucleus. Consistently, a MAPK specific inhibitor U0126 enhances nodule formation and confers similar nodule phenotypes to the efd-1 mutant such as lower proliferation and differentiation to symbiotic tissues. Our works thus reveal a key negative signaling module mediated by MtMKK5-MtMPK3/6-EFD for symbiotic nitrogen fixing nodule organogenesis. *Corresponding Author: Tel. 043-261-2293, E-mail: hjryu96@chungbuk.ac.kr -85-

The Consortium for the Barcode of Life (CBOL) plant-working group recommended the 2-locus combination as the standard plant barcode. The evolutions of the chloroplast regions combine with nuclear gens are sufficiently rapid to allow discrimination between closely related species. We evaluated the efficacy of the proposed plant barcoding loci matk along with ITS2 for barcoding Vigna species. To assess the discrimination ability of barcoding loci to resolve Vigna species, we sampled 52 of the taxonomically best known groups in the genus. Topologies of the phylogenetic trees based on ITS2 and matk analyses were similar but a few accessions were placed into distant phylogenetic groups. Neither ITS2 nor matk analyses were able to discriminate some closely related Vigna species alone. Thus, we used concatenated data to increase the resolving power of ITS2 and used matk as an additional tool for phylogenetic analysis in Vigna because characterization of the nucleotide sequences of matk region was easier to recover and more cost-effective than those of the ITS region. *Corresponding Author: Tel. +82-63-238-4872, E-mail: jwchung73@korea.kr PB-22 A New Peanut Variety Daan with High Yield and Disease Resistance Suk-Bok Pae *, Myung-Hee Lee, Sung-Up Kim, Chung-Dong Hwang, Ki-Won Oh, Chan-Sik Jung, Deuk-Young Song, In-Youl Baek, Young-Hee Lee Department of Southern Area Crop Science, NICS, RDA, Miryang 627-803, Korea Peanut is grown worldwide in the tropics and temperate zones primarily as an oilseed crop (38-54%) and protein source(25-30%).

The somatic metaphase chromosomes examined in this study were all diploids (2n = 18). Chromosomes were classified into five types based on the number and distribution of CMA positive bands; A: two telomeric and one proximal bands, B: one telomeric and one proximal bands, C: two telomeric bands, D: one telomeric band, E: no band. Four to five types of chromosomes and unique chromosome compositions were observed from each accession. The CMA banding patterns of Jeju citrus landraces were 1A+1B+1C+9D+6E in jinkyul, 1A+1B+1C+8D+7E in cheongkyul, 1B+1C+10D+6E in hongkyul, 2A+1B+3C+6D+6E in sadoogam, 1A+2B+1C+8D+6E in dangyooza, 1A+1B+3C+7D+6E in dong-geongkyul, 2B+2C+7D+7E in pyunkyul, 2A+2B+2C+6D+6E in gamza, 1A+2B+1C+7D+7E in byungkyul, 1A+1B+1C+9D+6E in jigak, 1A+1C+10D+6E in binkyul. Type D and E chromosomes were predominant in all Jeju citrus landraces. The chromosome composition with an even number distribution in gamza was observed, hence it could be recognized as a non-hybrid species. The results indicated all Jeju citrus landraces except gamza seemed to be hybrids, but might be diverged from species originated or cultivated in Jeju, Korea and other countries. *Corresponding Author: Tel. 064-754-3328, E-mail: kwansong@jejunu.ac.kr PB-34 Antioxidant activity and total phenolic and flavonoid contents of 10 Vicia species Kyung Jun Lee *, Gi-An Lee, Young-Ah Jeon, Jung-Ro Lee, Sok-Young Lee, Kyung-Ho Ma, Jong-Wook Chung National Agrobiodiversity Center, NAAS, RDA, Jeonju 560-500, Republic of Korea Flavonoids and total polyphenols are important secondary plant metabolites, as they play a role in reducing the oxidative stress caused by ROS In this study, we investigated for flavonoid contents, total polyphenol contents, and antioxidant activities in 27 accessions from 10 Vicia species.

PB-35 Genetic diversity base on agrinomical traits and SSR markers in Korean rice landraces Kyung Jun Lee *, Jong-Ro Lee, Gi-An Lee, Sebastin Raveendar, Kyung-Ho Ma, Sok-Young Lee, Jong-Wook Chung National Agrobiodiversity Center, NAAS, RDA, Jeonju 560-500, Republic of Korea In order to assess the genetic diversity, phylogenetic relationships and population structure of Korean rice landraces, 76 accessions were estimated using agronomical traits and SSR markers. Among 11 agronomical traits, amylose content (AC) was the trait with the largest variance with values ranged from 4.9 to 28.39 %, while grain length (GL) was the lowest variance ranged from 4.4 to 5.9 cm. In the result of PCA, the first PC with Eigen value of 217.5 explained 60.3% of the total variance. Culm length (CL) was the variable with the largest positive loadings. Growth period (GP) was the positive variances, while AC was the negative variance. The second PC with Eigen value of 80.6 explained an additional 22.4% of the total variance. Growth period (GP) was variable with highest positive loading. Amylose content (AC) was variable with high positive, while CL was the negative variance. The 49 SSR markers produced a total of 473 alleles with an average of 9.6 alleles. The polymorphism information content (PIC) was in the range 0.11 to 0.93. The observed heterozygosity ranged from 0.12 to 0.39, with an average of 0.61. 76 rice accessions showed two subpoplations and three groups based on SSR markers. Group I and Gropu II appertained Pop-2 and Pop-1 subpopulation, respectively. They showed similar agronomical traits. Group III consisted 7 rice accessions predominantly appertained to Pop-1.

Seed dormancy, one of domesticated traits, prevents pre-harvest sprouting (PHS) which causes degradation of grain quality in cereal crop. In previous study, we surveyed the variation of seed germinability of diverse 200 rice germplasm and detected the three distinguished groups besides admixed types; the first group (G-1) revealed high germinability at harvesting time, and the second group (G-2) and third group (G-3) acquired high germnability subsequent to after-ripening and dormancy breaking process, respectively. To reduce environmental effects on detected variation of germinability, we selected representative 14 accessions which have similar heading date of each group and measured the degree of PHS using freshly harvested panicles. Variation of PHS showed similar tendency of germinability group; generally, high PHS for G-1, low PHS for G-2 and no PHS for G-3. To resolve genetic and physiological factors concerning on PHS and seed dormancy, we checked the change and variation of ABA known for critical regulator for seed dormancy, and high PHS accessions interestingly revealed high ABA content in 10 DAF. Based on these study, we plan to analyze genetic factors affecting the degree of seed germinability and PHS. *Corresponding Author: Tel. 063-238-4883, E-mail: gkntl1@korea.kr -95-
PB-37 Brachypodium distachyon mutants induced by gamma radiation contain reduced lignin content Man Bo Lee, Yong Weon Seo * Dept. of Biotechnology, Korea University, Seoul 136-713, Republic of Korea It is necessary to alleviate environmental and economic disadvantages of fossil fuels for global warming. Among the conceivable options, the use of plant biomass for the production of bioethanol is considered as a potential alternative for fossil fuels. Plant biomass that contains lignocellulose for bioethanol production has recently emerged as biofuel feedstock because of its sustainable and environment-friendly properties. However, lignin inhibits the hydrolysis process and the lignin recalcitrance in ethanol conversion remains in a problem. The attempt for down-regulating enzymes involved in lignin biosynthesis is one of attractive strategy to reduce the lignin contents. Recently, Brachypodium distachyon has been proposed as an alternative monocotyledon model species. The close phylogenetic relationship of Brachypodium with other grasses suggests that the Brachypodium may be useful for structural and functional genomic studies in these species. Brachypodium, standard line Bd21, was subjected to irradiation at doses of 50, 100, 150, 200, and 250 Gy. Phenotypes were investigated using M 0:2 population. Through histochemical analysis using phloroglucinol, 25 M 2 putative lignin deficient mutants were selected. Depend on the phenotypic and histochemical data, mutants were selected and used for measuring lignin content. Total lignin content was measured using the acetyl bromide (AcBr). Mutant #142-3-1 contains 16.9 (mg/g dry cell wall) of total lignin and the lignin level was significantly reduced (87.9%) compared to wild-type (19.23 mg/g dry cell wall). Additionally, Mutant line #2259-1-2 reduced lignin level at 94.4% (18.15 mg/g dry cell wall) in comparison to wild-type. The enzymatic hydrolyses in lignin deficient lines have been performing with the time courses. Lignin composition, cell wall carbohydrates, and genetic analysis in mutant lines will be discussed.

PB-38 Development and characterization of endophyte free tall fescue variety Greenmaster3ho Sang-Hoon Lee *, Ki-Won Lee, Ki-Yong Kim, Hee Jung Ji, Tae Young Hwang, Hyung Soo Park, Hyun Seok Chae Grassland and Forages Division, National Institute of Animal Science, Rural Development Administration, Cheonan, 330-801, Republic of Korea In order to improve high persistence and forage quality, through selection of various superior parental varieties for breeding and synthesis of them with new lines, there are ongoing worldwide studies aiming to enhance the quality of tall fescue through a traditional breeding method by selection and hybridization. A new tall fescue variety (Festuca arundinacea Schreb.), named Greenmaster3ho, was developed by the National Institute of Animal Science, Rural Development Administration in Korea from 2010 to 2014. For synthetic seed production of this new variety, five superior clones, 09XFa02, 09XFa03, 09XFa11, 09XFa13, and 09XFa14 were selected and polycrossed. The agronomic growth characteristics and forage production capability of the seeds were studied at Cheonan from 2010, and regional trials were conducted in Cheonan, Hoengseong, Jeju, and Jinju from 2012 to 2014. Greenmaster3ho showed enhanced disease resistance, persistence, and regrowth ability as compared to Fawn. The dry matter yield of Greenmaster 2 was 29% higher (15,119 kg/ha) than that of Fawn.

PB-40 Evaluation of genetic diversity of Asian landrace wheat based on HMW glutenin subunit and maturity Sukyeung Lee, Yu-mi Choi, Do yoon Hyun, Myung-chul Lee, Sejong Oh, On sook Hur, Hocheol Ko, Na-Young Ro National Agrobiodiversity Center, NAAS, RDA, 560-500, Korea. Glutenin is the major factor responsible for the unique viscoelastic dough characterisitcs of wheat flour, which determine mixing and bread baking performance(x.shan et al, 2007). And early maturity is one of the most important cultural characteristic in Korea because of its winter cropping system. This study is to reveal the genetic properties of Asian wheat landrace collection originated from 6 separate regions such as Korea, China, Japan, Afganistan, Iran, Pakistan, Caucasus, and Middle East. Using germplasms maintained in National Agrobiodiversity Center, RDA, Korea, the variations in morphological character and HMW glutenin subunit composition were investigated. In this study, Glu-A1c(null), Glu-B1b(7+8) and Glu-D1a(2+12) alleles are the most frequent in Asian landrace wheats. When it comes to unique composition, Glu-B1aj(8) and Glu-D1q(2+11) subunits are only in Afghanistan wheat. And Glu-B1k(22), Glu-D1l(12), Glu-D1m(10) subunits are only in accessions from Pakistan, Korea, and China, respectively. The accessions from Iran and Caucasus have the highest PIC value(0.57), which shows wheat origin region has high genetic diversity. Grouping by UPGMA anlysis of combination of Glu-1 allele, most accessions from Afghanistan, Korea, and Japan were in the same group despite of geological distance. Contrasively, many germplasms originated from China, Caucasus, and Middle East were in the other same group. The evaluation of bread baking quality by Glu-1 scoring system, 34 accessions are perfect 10. 16 samples from China and 1 Afghanistan among them were also matured before early June, suitable to Korean cropping system. Especially, 3 accessions(k151847, K151865, K151962) had extremely early maturity, ripened before late May. These genetic resources having good gluten quality and early maturity are expected to be used for Korea wheat breeding system.

In this study, we assessed the genetic and phenotypic variation of 174 normal maize (Zea mays) inbred lines and made association analyses with respect to nine agronomical traits, using 150 simple sequence repeats (SSR). From population structure analysis, the lines were divided into three groups. Association analysis was done with a mixed linear model and a general linear model. Twenty one marker-trait associations involving 19 SSR markers were observed using the mixed model, with a significance level of P<0.01. All of these associations, as well as 120 additional marker-trait associations involving 77 SSR markers, were observed with the general model. Two significant marker-trait associations (SMTAs) were detected at P 0.0001. In the mixed linear model, one locus was associated with water content, two loci were associated with 100-kernel weight, setted ear length, ear thickness and stem thickness; three loci were associated with ear height, four loci were associated with total kernel weight and five loci were associated with plant height. These results should prove useful to breeders in the selection of parental lines and markers. *Corresponding Author: Tel. 033-250-6415, E-mail: jukyonglee@kangwon.ac.kr PB-47 고품질복합내병성벼신품종 새신 이지윤 1*, 이종희 2, 조준현 1, 오성환 1, 손영보 1, 황운하 3, 박수권 3, 신동진 1, 송유천 1, 박동수 1, 김상열 4, 박인희 1, 여운상 1, 최대식 1, 남민희 1, 이영희 1 1 경남밀양시점필재로 20 국립식량과학원남부작물부 2 전라북도전주시완산구농생명로 300, 농촌진흥청연구정책국 3 전라북도완주군이서면갈산리혁신로 181 국립식량과학원 4 경상북도영덕군병곡면원황길 44 국립식량과학원영덕출장소 새신 은밥맛이양호하면서복합내병성특히, 흰잎마름병 K 3a 에강한벼를육성하고자 2007/2008 년동계에중만생종이고쌀알이맑은고품질새누리를모본으로, 흰잎마름병 K 3a 에강하고수량성이높은품종인신백을부본으로교배하였다. 2008 년하계에양성한 F 1 개체로약배양을실시하여 96 개의재분화개체를얻었으며, 이중에서줄무늬잎마름병과 K 3a 에저항성이며, 농업적특성이우수한 YR27906Acp84 를선발하여 2 년간의생산력검정시험실시후밀양 273 호의계통명이부여하였다. 3 년간의지역적응시험결과복합내병성, 내도복성및수량성등의우수성이인정되어농작물직무육성신품종선정위원회에서 새신 으로명명되었다. * 주저자 : Tel. 055-350-1164, E-mail: minitia@korea.kr - 101 -

It was produced by vegetable crops and a lettuce is one of the crops. The general pathway of anthocyanin expression is well defined but it is not clear how environments effects on anthocyanin accumulation in a lettuce. Therefore we initiated to study interaction between anthocyanin expression and environment factors. Frist, we applied RGB leaf images in a lettuce to calculate anthocyanin areas in a leaflet with two different cultivars, different developmental stages, and different environments. Later, we attempted to capture RNA expression level with next generation sequence (NGS) RNA sequencing method called RNA-seq. As a result, combined two technologies showed that quantitate phenotypic data help to understand the gene expression of anthocyanin in lettuce cultivars. *Corresponding Author: Tel. 033-650-3660, E-mail: hkim58@kist.re.kr PB-51 Identification of Hybrids using SSR markers from Polyembryonic Citrus Breeding Lines.

So, it has become imperative for developing efficient methods to distinguish zygotic seedling generated from polyembryonic seed depending on citrus variety. Simple sequence repeat(ssr) marker is one of useful systems for such purpose. However, SSR markers to separate zygotic seedlings derived from the crossbreeding between Marita unshiu (Citrus unshiu) Seongjeon and Shiranuhi mandarin [(C. unshiu x C. sinensis) x C. reticulata] Hallabong have not been developed yet. In this study we tried to identify an effective SSR marker to screen zygotic seedling after crossbreeding between Seongjeon and Hallabong. For this investigation, 387 seedlings were generated from 114 seeds produced from crossing those two varieties. A total of 116 SSR markers were tested to identify a special marker for distinguishing origin, zygotic or nucellar seedling. As a result, two markers, SSR012 and SSR093, were found to be more effective than other markers. These two SSR markers might be useful to select zygotic individuals in crossbreeing between Seongjeon and Hallabong.

Three mutant cultivars (Jangdae, Jeokbong and Baekma), two original cultivars (Jinju, C14), and one Chinese cultivar (Auxu) were planted on May 14, 2013. Four harvesting times were made at intervals of 20 days from 15 July to 16 September, 2013. The overall growth characters of mutant cultivar Jeokbong such as plant height, stem diameter, flowering time, and dry mass were similar with those of the original variety. The mutant cultivar Baekma occurred 10-day late flowering in comparison with the original variety and also displayed higher dry mass than the original variety. Jinju, Auxu and Jangdae, mid-late maturing kenaf cultivars, had high dry weight compared to early maturing cultivars such as Jeokbong, Baekma and C14. In all cultivars, the lignin contents were increased by a late harvest. The Mid-late maturing kenaf cultivars showed high lignin content in comparison with those of the early maturity cultivars. There were no significant differences of cellulose, and hemicellulose content between the cultivars, however cellulose content in stems of these kenaf cultivars were significantly decreased by a late harvest. These results may provide valuable information to assist the parental selection of kenaf breeding. *Corresponding Author: Tel. 063-570-3310, E-mail: sykang@kaeri.re.kr PB-53 Complete chloroplast genome sequence of Capsicum baccatum var. baccatum Tae-Sung Kim 1, Jung-Ro Lee 2, Sebastin Raveendar 2, Gi-An Lee 2, Young-Ah Jeon 2, Ho-Sun Lee 2, Eun Seong Park 1, Kyung-Ho Ma 2, Sok-Young Lee 2, Jong-Wook Chung 2* 1 Department of Plant Resources, College of Industrial Sciences, Kongju National University, Yesan, 340-702, Korea 2 National Agrobiodiversity Centre, National Academy of Agricultural Science, Rural Development Administration, Jeonju 560-500, Korea The chloroplast (cp) is an organelle with its own genome that encodes a number of cp-specific components.

PB-55 The Complete Chloroplast Genome Sequence of Korean Landrace Subicho (Capsicum annuum var. annuum) Sebastin Raveendar, Young-Ah Jeon, Jung-Ro Lee, Gi-An Lee, Kyung Jun Lee, Yang-Hee Cho, Kyung-Ho Ma, Sok-Young Lee, Jong-Wook Chung * National Agrobiodiversity Centre, National Academy of Agricultural Science, Rural Development Administration, Jeonju 560-500, Republic of Korea Chloroplast DNA sequences are a versatile tool for species identification and phylogenetic reconstruction of land plants. Different chloroplast loci have been utilized for phylogenetic classification of plant species. However, there is no evidence for a short sequence that can distinguish all plant species from each other. Molecular markers derived from the complete chloroplast genome can provide effective tools for species identification and phylogenetic resolution. Thus, the complete chloroplast genome sequence of Korean landrace Subicho pepper (Capsicum annuum var. annuum) has been determined here. The total length of the chloroplast genome is 156,878 bp, with 37.7% overall GC content. A pair of IRs (inverted repeats) of 25,801 bp was separated by a small single copy (SSC) region of 17,929 bp and a large single copy (LSC) region of 87,347 bp. The chloroplast genome harbors 132 known genes, including 87 protein-coding genes, 8 ribosomal RNA genes, and 37 trna genes. A total of seven of these genes are duplicated in the inverted repeat regions, nine genes and six trna genes contain one intron, while two genes and a ycf have two introns. Analysis revealed 144 simple sequence repeat (SSR) loci and 96 variants, mostly located in the non-coding regions. The types and abundances of repeat units in Capsicum species were relatively conserved and these loci will be useful for developing molecular markers. *Corresponding Author: Tel. +82-63-238-4872, E-mail: jwchung73@korea.kr PB-56 The complete chloroplast genome of Capsicum annuum var. glabriusculum using Illumina sequencing Sebastin Raveendar 1, Jung-Ro Lee 1, Donghwan Shim 2, Kyung Jun Lee 1, Kyung-Ho Ma 1, Sok-Young Lee 1, Jong-Wook Chung 1* 1 National Agrobiodiversity Centre, National Academy of Agricultural Science, Rural Development Administration, Jeonju 560-500, Republic of Korea 2 The Agriculture Genome Center, National Academy Agriculture Science, RDA, Jeonju, Jeonbuk, Republic of Korea Chloroplast (cp) genome sequences provide a valuable source for DNA barcoding. Molecular phylogenetic studies have concentrated on DNA sequencing of conserved gene loci. However, this approach is time consuming and more difficult to implement when gene organization differs among species. Here we report the complete re-sequencing of the cp genome of Capsicum pepper (Capsicum annuum var. glabriusculum) using the Illumina platform. The total length of the cp genome is 156,817 bp with a 37.7% overall GC content. A pair of inverted repeats (IRs) of 50,284 bp were separated by a small single copy (SSC; 18,948 bp) and a large single copy (LSC; 87,446 bp). The number of cp genes in C. annuum var. glabriusculum is the same as that in other Capsicum species. Variations in the lengths of LSC, SSC and IR regions were the main contributors to the size variation in the cp genome of this species. A total of 125 simple sequence repeat (SSR) and 48 insertions or deletions variants were found by sequence alignment of Capsicum cp genome. These findings provide a foundation for further investigation of cp genome evolution in Capsicum and other higher plants. *Corresponding Author: Tel. +82-63-238-4872, E-mail: jwchung73@korea.kr - 106 -

Fortification with vitamins in rice is a feasible solution to directly reach consumers who suffer nutritional problems. In this study, we are working on tryptophan, a limiting amino acid in almost all protein sources which are of importance for human nutrition. The present high tryptophan rice lines are much higher tryptophan level in mature seeds than wild type, however, the grain quality is very low. We try to improve the eating quality of the current high tryptophan rice lines by crossing them to popular Korean varieties, Hopumbyeo and Samgwangbyeo. Insensitive lines for tryptophan feedback inhibition are screened by growing in medium containing amino acid analogues, 5-methyl tryptophan. In vitro screening of each progenies enables us to select in each generation the rice lines with tolerance to 5-methyl tryptophan.

This study was conducted to investigate the effects of growth temperature for sprouting soybean. Soybean sprouts showed different growth characteristics, nutrient composition and secondary metabolite depending on temperature. Sprout qualities such as whole length, hypocotyl length and yield increased at high temperature condition (25 ) than at low temperature condition (20 ). Total protein also increased at 25, while total fatty acid decreased at 20. Total phenolic content of pungwongkong sprout was higher at 25, while total phenolic content of pungsankong sprout was lower at 25. The antioxidant activity increased temperature dependently. Both DPPH activity and ABTS activity were higher at 25. To understand proteomic profiles from soybean sprouts germinated at different temperature, proteomic analysis was conducted and protein compositions were compared. 33 spots were differentially expressed and were identified using MALDI-TOF mass spectrometer. They were mainly involved in storage proteins, stress related proteins and metabolism related proteins. The results suggest that growth temperature could affect on protein profile change related to secondary metabolite in sprouts and consequently could alter sprout characteristics.

Amylose content is a leading factor affecting eating quality of rice. Amylose composition is determined by the relative activity of soluble starch synthase (SSS) and granule-bound starch synthase (GBSS). This study focused on modifying the expression of SSSI gene which is responsible for amylopectin and amylose synthesis in rice by using RNA interference (RNAi) technology. The transgenic rice plants showed various amylose content in rice grains. Favorable rice lines were selected according to genomic PCR, transgene expression and amylose contents analysis. A semi-quantitative RT-PCR was carried out to determine the expression level of SSSI gene after flowering of transgenic rice and wild type. Down-regulation of SSSI gene in transgenic plants was evident in the decreasing expression in rice grains. Accordingly, scanning electron microscopy (SEM) analysis revealed uniform size with smooth curves starch granules in down-regulation rice lines, in contrast with the non-uniform granules in wild type. Results indicated that RNAi-SSSI transgenic lines produced low amylose contents that fell between glutinous and non-glutinous rice. This study showed that down-regulation of endogenous SSSI may improve the eating quality in rice.

PB-67 Growth and Yield characteristics of Orchardgrass Onnuri 2 ho Variety Hee Chung. Ji 1*, Ki Yong. Kim 1, Tae Young Hwang 1, Hyun Seok Chae 1, Seong Tae Lee 2 1 Grassland & Forages Research Center, National Institute of Animal Science, RDA, Cheonan 331-808, Republic of Korea 2 Agricultural Research & Extension Services, Gyeongsangnam-Do, 660-985, Republic of Korea. Orchardgrass (Dactylis glomerata L.) is a Gramineae perennial grass species and commonly used as a forage crop and developed to be used for pasture. In Korea, in order to improve high persistence and forage quality, through selection of various superior parental varieties for breeding and synthesis of them with new lines, there are ongoing worldwide studies aiming to enhance the quality and environmental adaptability of Orchardgrass. Between 2010 and 2014, a Orchardgrass variety named Onnuri 2ho was developed by the Grassland & Forages Division, National Institute of Animal Science, Rural Development Administration (RDA), Republic of Korea. For the production of synthetic seeds for Onnuri 2ho 4 superior clones, Dg7506, Dg9508, Edg215 and Edg218 were selected and polycrossed. Between 2010 and 2011, the agronomic growth characteristics and forage production capability of the seeds were studied at Cheonan, and between 2012 and 2014, regional trials were conducted in Cheonan, Hoengseong, Jinju, and in Jeju. The main growth characteristic of Onnuri 2ho is a tetraploid variety, a medium-late maturity variety, the heading stage of which is around May 17, which is four days later than that of Amba. This study tested the regional adaptability of Orchardgrass in Cheonan, Hoengseong, Jeju, and in Jinju. The average dry matter yield of Onnuri 2ho in the four regions was 15,814 kg/ha, which is greater than that of Amba by 34%. These differences show that Onnuri 2ho is more resistant to environmental stresses than Amba and that this growth characteristic directly led to dry matter yield. Thus, Onnuri 2ho is a suitable variety for the establishment of grasslands as it has enhanced disease resistance and persistence, compared to Amba. The forage quality of Onnuri 2ho was similar to that of Amba in crude protein (11.5%), total digestible nutrients (59.2%), neutral detergent fiber (62.7%), and acid detergent fiber (37.6%), whereas the forage quality of Ongreen was higher than that of Amba in (71.0%). The new variety was selected and named Onnuri 2ho from Composite 34 by the RDA in November 2014, and the application for the protection of the new variety by the Korea Seed and Variety Service is currently pending.

PB-76 Gibberellin Application at Pre-bloom in Grapevines Alters GABA-shunt Resulting in Accumulation of GABA (γ-aminobutyric acid) at Full Bloom Chan Jin Jung, Youn Young Hur *, Sung-Min Jung, Sang-Uk Koh, Jong-Chul Nam Fruit Research Division, National Institute of Horticultural and Herbal Science, RDA, Wanju 565-850, Korea The GA application on grapevines induces parthenocarpy, fruit set without fertilization, and the inhibition of pollen tube growth. But the molecular mechanism underlying this inhibition is not understood. Similar defective pollen tube growth within the transmitting tract has been reported in the mutant of GABA transaminase (GABA-T), referred to as pollen-pistil-interaction2 (pop2) in Arabidopsis. In spite of the similarity of pollen tube growth inhibition observed in GA-applied grapevines with that of pop2, only the effects of GABA on stress responses in grapevines have been reported. In present study, transcriptional changes of Vitis GABA metabolic genes, together with changes in GABA levels with or without GA application were analyzed to define how GA application restrained the pollen tube growth in grapevines. A GA solution (Dongbu, Seoul, Korea) at 100 ppm was onto inflorescence clusters 14 days before full bloom (DBF) and clusters were harvested at 0, 1, 2, 4, 7, 9, 12, 14, 16, and 19 days after GA application. Harvested inflorescence samples were immediately frozen in LN 2 and extracted RNA and amino acid. The GABA contents were analyzed using high-performance liquid chromatography (Agilent 1100 HPLC, Agilent Technologies, Inc., Santa Clara, USA) equipped with a C18 column (4.6 mm 150 mm, 3.5 µm/vds optilab, Berlin, Germany), according to the manufacturer s instructions. Without GA application, the simultaneous high expressions of VvGAD1, VvGAD4 and VvGABA-T2 during 10 to 5 days before full bloom (DBF) showing the activation of GABA metabolism. But the contents of GABA were low before 2 DBF, and it peaked only at near full bloom when expression levels of VvGABA-T2 remained low. After GA application, the contents of GABA were constant during 10 to 5 DBF, although transcription levels of both VvGAD1 and VvGABA-T2 rapidly declined less than 30% of the levels observed without GA application. However, the GABA levels increased more than 2-fold only at near full bloom, compared to those without GA application, and at that time, expression levels of VvGAD1 up-regulated more than 3-fold and those of VvGABA-T2 kept low. But other amino acid contents did not show significant changes. In case of VvSSAHDs, their transcriptional changes with or without GA application were not correlated with GABA levels. These results indicates that GABA levels before pollination is tightly regulated, but GA application alters the GABA-shunt to accumulate excess GABA more than needed for proper pollen tube growth at full bloom. Gibberellin application alters the GABA-shunt to accumulate excess GABA resulting in inhibition pollen tube growth in grapevines. *Corresponding Author: Tel. 063-238-6743, E-mail: yyhur76@korea.kr - 121 -

Sch. Agr. Life Sci., Univ. Tokyo 2 Center for Sustainable Resource Science, RIKEN 3 Fruit Research Division, National Institute of Horticultural and Herbal Science, RDA, Wanju 565-850, Korea As one of the most severe stress conditions, drought strongly affects the plant growth and productivity. OsPIL1, a gene encoding a rice Phytochrome Interacting Factor (PIF)-Like transcription factor, was found to be down-regulated under drought stress condition. OsPIL1 shows a diurnal expression pattern and known to be involved in regulation of plant height. However, the mechanisms of down-regulation of OsPIL1 expression under stress conditions are remained unclear. In this study, the expression of PIF4 and PIF5, the most homologous genes of OsPIL1 in Arabidopsis, was analyzed and the expression of these genes were found to be oscillated in circadian manner and down-regulated in response to drought and low temperature similar to that of OsPIL1. To identify the regions involved in the responses to drought, low temperature and diurnal cycle, the promoter analysis of PIF4 was performed using transgenic Arabidopsis. Further promoter analysis is ongoing to specify regulatory regions in more detail. *Corresponding Author: Tel. 063-238-6743, E-mail: gsmoon@chol.com PB-80 Characterization of the Koji (Aspergillus oryzae) in four wheat varieties Jong-Nae Hyun 1*, Hyung-ho Park 1, Kyung-Hun Kim 1, Kyung-Min Kim 1, Jee-Yeon Ko 1, Young-Up Kweon 1, Chon-Sik Kang 2, Sang-Jong Lim 2, Jae-Hyun Kim 3 1 Department of Southern Area, NICS, Miryang, 627-803, Republic of Korea 2 National Institute of Crop Science, Jeonju, 560-500, Republic of Korea 3 National Academy of Agricultural Science, Jeonju, 560-500, Republic of Korea Koji (Aspergillus oryzae) is used to ferment crude cereals of wheat to make a traditional alcoholic drink called Makkolli and industrial materials.

The local adaptability test of MRXII-1001-1 was carried out from 2012 to 2014 and it was named as Tocomi-1 in 2014. This variety is medium matured with heading date of August 12 in honam plain area of Korea. This variety is about 80 cm tall culm length and 106 spikelets per panicle. Its 1,000 grain-weight of rice seeds is 25.4 g. The yield potential of this variety is about 5.15 MT/ha in local adaptability test for three years. This variety exhibited greater seed longevity than the Donganbyeo, indicating a crucial role for tocopherols in maintaining viability during quiescence, and displayed faster seedling growth during the early growth stage. Tocopherol contents was 50% higher than the Donganbyeo. To study the molecular mechanism underlying vitamin E biosynthesis, we examined the expression patterns of seven rice genes encoding vitamin E biosynthetic enzymes. Accumulation levels of the OsVTE2 transcript and OsVTE2 protein in the Tocomi-1 were significantly higher than in the Donganbyeo. Sequence analysis revealed that the Tocomi-1 harbored a point mutation in the OsVTE2 promoter region, which resulted in the generation of MYB transcription factor binding cis-element. These results help identify the promoter regions that regulate OsVTE2 transcription, and offer insights into the regulation of tocopherol content in Tocomi-1. *Corresponding Author: Tel. 063-570-3311, E-mail: bioplant@kaeri.re.kr - 125 -

PC-01 Genetic Analysis and Fine Mapping of Panicle Tip Mutant pnt in rice (Oryza sativa L.) Abebe Megersa Diriba, Dongryung Lee, Jeonghwan Seo, Backki Kim, Zhuo Jin, Hee-Jong Koh * Department of Plant Science, Research Institute of Agriculture and Life Science, and Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-921, Korea. In the rice inflorescence development, timing of inflorescent meristem abortion, conversion of the rachis branch meristem to the terminal spikelet meristem and shift to lateral meristem identity determine the overall architecture of the rice panicle (keda-kawakatsu et al. 2009). Cheng et al. (2011) reported that quantitative trait loci (QTLs) have major effects on panicle apical abortion in rice. However, there have been very few reports about panicle tip mutants. Therefore, this research is conducted to fine map mutant gene and perform functional analysis of mutant gen. Hwacheongbyeo (japonica rice) seed was treated with ethyl methane sulfonate (EMS) for inducing mutation. Two F2 population (Japanica mutant crossed with wild type and Japanica mutant crossed with Milyang 23, Indica type) were established for Phenotyping and genomic analysis. STS markers in crop molecular Breeding laboratory. Additional STS markers for fine mapping were developed based on the Nipponbare genome sequence (http://rgp.dna.affrc.go.jp/blast/runblast.html). All F2 generations showed the segregation of normal plants and mutant following a ratio of 3:1 suggesting the mutant phenotype is caused by a single recessive gene. Initial BSA test made using STS markers confirmed the mutant gene is found in the long arm of chromosome 8. Panicle tip mutant gene, pnt has pleotropic effect which has been manifested in significant reduction of tiller development starting from late stage of vegetative growth and pronounced effect on possession of stay green nature of the rice during the vegetative stage of development. The only significant difference observed within panicle traits is the number of spikelet on primary branch and spikelet fertility. The first primary branch which contain aborted spikelet and elongated distance between spikelet is the most affected structure in the panicle.

Based on OGRO database information, function of only 1022 genes were characterized previously where estimated expressed genes is approximately 50000. TFs protein class consist of 80 families and function of only 211 were reported. To address this issue, we developed web resource using MySQL, PHP and related frame work. Database integrates expression pattern and diverse data in phylogenomic contest. Since TFs plays diverse role in plants, meta-expression analysis would provide putative function of remaining genes. Using this approach and in-house database, we have identified featured expression groups: 228 belongs to anatomy, 224 to abiotic stress, 202 to biotic stress and hormone responsive group includes 267 genes. Out of 315 known genes through loss of functional studies, 294 genes have no closely related family members. Among 12 pairs with probes in database, 6 genes have PCC value with more than 0.5 among closely related genes. These data suggest that TFs showing more than 0.5 PCC value among closely relating family members more likely have functional dominancy. This study will provide useful functional information for whole rice TFs and suggest promising functional genomic studies. *Corresponding Author: E-mail: khjung2010@khu.ac.kr - 127 -

Here, we demonstrated gametophytic mutant line, named as AP-28-23, in which mutant gene was mapped on chromosome 2. Based on phenotypic analysis of mature pollen, mutant phenotype of AP-28-23 was classified into three classes, wild-type showing 2-4%, moderate 35-53% and severe type 97-100% on aberrant pollen frequencies, respectively. The severe type is completely sterilized with 100% unfertilized ovules. We also revealed that the transmission was reduced through male gametophyte in the AP-28-23 line. The transmission efficiency (TE) through the male gametophyte is only 0.67%, whereas in the female gametophyte is 89.87%. *Corresponding Author: Tel. 053-950-7751, E-mail: psk@knu.ac.kr PC-04 Molecular characterization and functional analysis of the UDP-glucose 4-epimerase (BrUGE) gene family in response to biotic and abiotic stress in Chinese cabbage (Brassica rapa) Yu Jin Jung 1,2, Boo Min Yun 1, Hyun Ji Kim 1, Yong Gu Cho 3, Ill Sup Noh 4, Kwon Kyoo Kang 1,2* 1 Department of Horticulture, Hankyong National University, Ansung, 456-749, Korea 2 Institute of Genetic Engineering, Hankyong National University, Ansung 456-749, Korea 3 Department of Crop Science, Chungbuk National University,Cheongju, 361-763, Korea 4 Department of Horticulture, Sunchon National University, Sunchon, 540-742, Korea UDP-glucose 4-epimerase (UGE; EC 5.1.3.2) is an enzyme that plays an essential role in the interconverts UDP-D-glucose (UDP-Glc) and UDP-Dgalactose (UDP-Gal). Five members of the Chinese cabbage (Brassica rapa) UDP-glucose 4-epimerase gene family, designated BrUGE1 to BrUGE5, have been cloned and characterized. Quantitative PCR shows that the BrUGE1and BrUGE4 mrna are most abundant among other BrUGE genes, accounting for more than 55% of total BrUGE transcripts in most of the tissues examined. All genes showed organ specific expression pattern, two of which (BrUGE1 and 4) actively responded after Pectobacterium carotovorum subsp. carotovorum infection, while four genes (BrUGE-1, -3, -4 and -5)were shown to respond considerably against salt, drought and abscisic acid (ABA) treatments. To better understand the function of the UGE gene, we constructed a recombinant part vector carrying the BrUGE1 gene under the control of the CaMV 35S promoter and nos terminator and transformed using Agrobacterium tumefaciens. We then investigated BrUGE1 overexpressing rice lines at the physiological and molecular levels under biotic and abiotic stress conditions. Bioassay of T 3 progeny lines of the transgenic plants in Yoshida solution containing 120 mm Nacl for 2 weeks, confirmed that the BrUGE1 enhances salt tolerance to transgenic rice plants. Also T 3 progeny lines of the transgenic plants, when exposed to infection caused by Xanthomonas oryzae pv oryzae, showed tolerance to bacterial blight. These results showed that BrUGE1 can be used as potential genetic resource for engineering Brassica with multiple stress resistance. - 128 -

Previously we showed that sy-2 leaves were irregularly shaped and defective in chlorophyll development at temperatures below 24. A segregation test revealed that the sy-2 gene is controlled by a single recessive gene. To identify the sy-2 gene, we performed a map-based cloning approach using a total 600 individual F 2 plants derived from crossing sy-2 and the wild type C. chinense No.3341. Fine-mapping of the locus allowed us to position sy-2 to an approximately 170-kb region flanked by markers IN2-1-1 and SNP-3-7 on chromosome 1. Among the approximately 36 hypothetical genes in this region several candidate genes including: HSP90-like ATPase family proteins, lipid-transfer proteins, calmodulin-domain protein kinases, and zinc finger proteins (ZFPs) were identified.

Control measures are proved ineffective, so breeding resistant cultivars are the most promising strategy against the pathogen. Resistance against P. capsici is governed by quantitative trait loci (QTL). According to previous studies on QTL detection, the QTL on pepper chromosome 5 is a major contributor to resistance. In this study, to exploit the involvement of this QTL and identify its contributing genes, the F 2 population derived from a cross between ECW30R and CM334 was inoculated with a medium virulence P. capsici strain JHAI1-7 zoospores at the 6-8 leaf stage. Composite interval mapping revealed two major QTLs; QTL5-1 from 7 days post inoculation (dpi) and QTL5-2 from 16 dpi on chromosome 5. To characterize and detect interactions of the two QTLs, near isogenic lines (NIL) were constructed by crossing Tean and recombinant inbred line (RIL) derived from a cross between YCM334 and Tean. RILs were screened with P. capsici strain MY-1 and resistant lines were selected. Among the resistance RILs most closely related to Tean were selected using AFLP and SSR genotyping data. These RILs were named as YT39-2 and YT143-2. To develop more advanced NILs, two rounds of marker-assisted backcrossing were done using a high-throughput SNP genotyping system (EPI Fluidigm, USA). Among the NILs derived from YT39-2, YT39-2-64 contains only QTL5-1 whereas YT39-2-61 and YT39-2-69 were identified to have both QTLs. On the other hand, YT143-2-55-7 with the highest Tean genetic background contains QTL5-1 only. In the next step, the 3 different NILs having QTL5-1, QTL5-2 individually and both QTLs will be identified.

In addition, this study was to establish pear DNA fingerprinting data for Korean native pears using 12 microsatellite markers, and to accurately classify a database for management of the Korean pear collection. Forty two pear accessions (7 primary pears, 5 Asian pears, 29 Korean pears, and 2 reference pears) were analyzed with twelve primers covering whole pear genome. In the present study, all pear accessions were successfully classified along with their pedigrees, and the distribution of primary pears was parallel to those of the previous taxonomic results. Korean pears were divided into 3 groups. Group I was characterized by Pyrus calleryana, and included Korean pea pears. Group II was characterized by P. pyrifolia, and was classified into 2 small groups. The first small group comprised of Najucheongbae, Sunchanggulimdolbae, Andongmookbae, Andongdangsilri, and Najucheongbae and was presumed to be cultivars of P. pyrifolia. The second small group consisted of Cheongdangrori and Pyeongchangsuhyangri. These two accessions were assumed to be a hybrid of P. pyrifolia and the other cultivar. Group III was characterized by P. ussuriensis. Goesanhwangbae, Andongcheongsilri, Gongjucheongsilri, and Yecheoncheongbae were assumed to be cultivars of P. ussuriensis. Contrary to Ulreungdocheongbae A, Ulreungdocheongbae B was classified as belonging to the P. ussuriensis group. It is possible that this is a consequence of, P. ussuriensis genes being transferred into Ulreungdocheongbae B. The result of this research reaffirmed the efficiency of a standard set of microsatellite markers and provides data, which will be useful for developing a core collection of pears. *Corresponding Author: Tel. 043-261-2527, E-mail: dkpomo@cbnu.ac.kr - 138 -
PC-17 Distinct roles of E3-paralogue genes promote early flowering in late flowering soybean cultivars Kil Hyun Kim 1, Min-Jung Seo 1, Jin-Seok Lee 1, Hwan Hee Bae 1, Jung-Tae Kim 1, Beom-Young Son 1, Seong-Bum Baek 1, Jeom-Ho Lee 1, Jung-Kyung Moon 2, Chang-Hwan Park 1* 1 National Institute of Crop Science, RDA, Suwon, 441-857, Republic of Korea 2 National Institute of Crop Science, RDA, Wangju, 565-238, Republic of Korea Soybean (Glycine max (L.) Merr) is a short day plant and has been adapted to various climates and environments during cultivation. However, the cultivation area is restricted to a very narrow range of latitudes. To date, nine major genes (E1 to E8 and J) have been reported to control the flowering time and maturity. Here, we evaluated the role of E2, E3, E4, and their paralogue genes in late flowering soybean cultivars under long day (LD) conditions using Soybean yellow common mosaic virus (SYCMV)-based virus-induced gene silencing (VIGS) system. A total of nine VIGS constructs were infiltrated into two fully expanded cotyledons and primary leaves. After inoculation with these VIGS constructs on Jangyeobkong, which is a late-flowering cultivar, phenotypic traits were evaluated for the first flowering dates (FFDs) and pod maturities under LD conditions. The FFDs of the silenced plants occurred 50-56 days after sowing (das), while the non-silenced plants bloomed on 60-61 days. We found that the E3 paralogue-silenced plants flowered the fastest and responsive genes were identified to be associated with the promotion of flowering time. As the knock-down of E3 paralogue, expression of E1 was up-regulated, E2 was no difference, E3 and E4 genes were down-regulated in the silenced plants. Expression of GmFT2a and GmFT5a is known to be controlled by E3 and E4. Interestingly, GmFT5a were highly expressed in SYCMV:E3 paralogue-silenced plants, whereas the expression of GmFT2a was not significant. These results support that GmFT5a is able to independently promote flowering under LD conditions. *Corresponding Author: Tel. 031-695-4046, E-mail: park6725@korea.kr - 139 -

Even though medicinal component and its effect of Panax ginseng was well studied, the genomic study has been recently started. The ginseng genome has been known to undergo two rounds of whole genome duplication (WGD), therefore we investigated an evidence of WGD in ginseng draft sequence for understanding current ginseng genome structure. Four paralogous gene-rich genome blocks were found, consisted by eight scaffolds, using about 3.0 Gb whole genome draft sequence and 48,821 unigenes of P. ginseng generated by whole genome shotgun sequencing. The eight scaffold sequences were ordered and connected into four genomic blocks, using zig-zag extension within scaffold sequences recently duplicated. The paralogous scaffold pairs that were recently duplicated showed high sequence conservation in genic and non-genic regions. However, paleo duplicated paralogue scaffold sequences showed little conservation only in genic regions. Finally, a total of 110 paralogous gene pairs and its expression were identified from recently and paleo duplicated scaffold pairs, which were co-linear among four genomic blocks. This study provides the first insight into duplicated genome structure of ginseng and will be a valuable information for further ginseng genomics including improvement of draft sequence quality, chromosome anchoring of scaffolds, and genetic mapping.

PC-19 Identification and characterization of novel phosphate starvation signaling mutant in Arabidopsis Hyun Jin Chun, Mi Suk Park, Byung-Jun Jin, Min Chul Kim * Division of Applied Life Science (BK21 Plus), Plant Molecular Biology and Biotechnology Research Center, Gyeongsang National University, Jinju 660-701, Korea. To identify novel signaling components involved in regulation of plant responses to phosphate (Pi) starvation, we screened an Arabidopsis T-DNA activation tagging library for mutants with altered Pi-starvation responses. Here, we report the identification and characterization of novel activation-tagged mutant involved in Pi starvation signaling in Arabidopsis. The hpd (hypersensitive to Pi deficiency) mutant exhibits enhanced phosphate uptake and altered root architectural change under Pi starvation compared to wild type. Expression analysis of auxin-responsive DR5::GUS reporter gene in hpd mutant indicated that both auxin biosynthesis and auxin translocation under Pi starvation are suppressed in hpd mutant plants. Impaired auxin translocation in roots of hpd mutant was attributable to abnormal root architecture changes in Pi starvation conditions. Mis-regulation of auxin translocation in hpd mutant was further confirmed by analysis of expression patterns of auxin efflux carrier proteins, PIN-FORMED (PIN) 1, 2, and 3 fused with GFP. Not only expression levels but also expression domains of PIN proteins were altered in hpd mutant in response to Pi starvation. Molecular genetic analysis of hpd mutant revealed that the mutant phenotype is caused by the lesion in ENHANCED SILENCING PHENOTYPE4 (ESP4) gene whose function is proposed in mrna 3 -end processing. The results propose that mrna processing plays crucial roles in Pi homeostasis as well as developmental reprograming in response to Pi deprivation in Arabidopsis. *Corresponding Author: Tel. 055-772-1874, E-mail: mckim@gnu.ac.kr - 141 -

Adapted cells to high salt exhibited enhanced tolerance compared to control cells. Moreover, the salt tolerance of adapted cells was stably maintained even after the stress is relieved, indicating that the salt tolerance of adapted cells was memorized. Salt-adapted and stress memorized cells were densely aggregated and formed multi-layered cell lump. Cell morphology analysis using transmission electron microscopy indicated that cell wall thickness of salt-adapted cells was significantly induced compared to control cells. In order to characterize metabolic responses of plant cells during adaptation to high salt stress as well as stress memory, we compared metabolic profiles of salt-adapted and stress-memorized cells with control cells by using NMR spectroscopy. A principle component analysis showed clear metabolic discrimination among control, salt-adapted and stress-memorized cells. Compared with control cells, metabolites related to shikimate metabolism such as tyrosine, and flavonol glycosides, which are related to protective mechanism of plant against stresses were largely up-regulated in adapted cell lines. Moreover, coniferin, a precursor of lignin, was more abundant in salt-adapted cells than control cells. The results provide new insight into metabolic level mechanisms of plant adaptation to saline stress as well as stress memory. *Corresponding Author: Tel. 055-772-1874, E-mail: mckim@gnu.ac.kr - 142 -
PC-21 Integrating Omics Analysis of Salt Stress-Responsive Genes in Rice Seo-Woo Kim, Hee-Jeong Jeong, Ki-Hong Jung Graduate School of Biotechnology & Crop Biotech Institute, Kyung Hee University, Yongin 446-701, Korea The detrimental effect of high salinity on crop production is a serious problem. However, the number of genes with known functions relating to salinity tolerance is very limited in rice. To effectively address this limitation, selection of useful candidate genes and identification of major regulatory factors through global approaches are necessary. To this end, we used three data series of affymetrix array data produced with salt-treated samples from NCBI Gene Expression Omnibus (http://www.ncbi.nlm.nih.gov/geo/) and identified 653 rice genes commonly differentially expressed under three salt-stress conditions. While evaluating the quality of selected candidate genes for salt-stress responses, Gene ontology enrichment analysis revealed that responses to salt and water stresses of biological process category are highly overrepresented in salt-stress conditions. In addition, the major salt stress-responsive metabolism process and regulatory gene modules are classified through MapMan analysis, and detailed elements for further studies are suggested. Based on this, we proposed a salt stress-responsive signaling pathway in rice. The functional analysis of the main signal transduction and transcription regulation factors identified in this pathway will shed light on a novel regulatory metabolism process that can be manipulated to develop crops with enhanced salinity tolerance.

Seongjun Kim, Sunggil Kim * Department of Plant Biotechnology, Chonnam National University, Gwangju 500-757, Republic of Korea For efficient introgression of the downy mildew resistance gene from a resistant cultivar into domestic breeding lines, molecular markers used for marker-assisted backcrossing (MAB) were developed in onion (Allium cepa L.). The resistance gene (Pd) was originally introgressed from a wild species, A. roylei, by interspecific hybridization, and the resistant gene was known to be positioned at the end of chromosome 3. Therefore, cdna sequences of loci located at the ends of chromosome 3 of two linkage maps were obtained from a transcriptome database. Primer pairs were designed on exon sequences of eight loci. Among them, the PCR products of the i25255 locus showed length polymorphism between A. roylei and onions, and both large and small-sized PCR products were observed in the resistant cultivar. Sequence analysis showed that a 67-bp indel existed in the intron sequences. Based on this indel polymorphism, a simple PCR marker, designated DMR1, was developed. Analysis of diverse onion accessions showed that no accessions contained the A. roylei-specific marker genotype except for the resistant cultivar. These results indicated that the DMR1 marker was successfully tagging the A. roylei fragment harboring the downy mildew resistance gene, and the resistant cultivar was heterozygous for the resistance gene. After further analysis of multiple loci positioned at chromosome 3, a range of the A. roylei fragment introgressed in the resistant cultivar was determined in two linkage maps. On the basis of the range of the A. roylei fragment, three molecular markers used for recombinant selection in MAB were also developed. *Corresponding Author: Tel. 062-530-2061, E-mail: dronion@jnu.ac.kr - 143 -

Two inbred lines (NH-JS1 and NH-JS2) showing opposite phenotypes of flowering time were selected to generate F2 population for the analysis. NH-JS1 showed late flowering time whereas NH-JS2 early flowering time. Genomic DNA from the two lines were extracted and sequenced. In addition F2 population from F1 between NH-JS1 and NH-JS2 was generated and flowering time phenotypes of 180 F2 plants were analyzed. We selected 11 plants with late flowering time and 12 plants showing early flowering time. We extracted DNA from each individuals from the two groups and bulked them to generate two bulked DNA samples that are subject to whole genome resequencing. Preliminary analysis of SNP data from the resequencing showed that there may be several QTLs involved in flowering time control in radish. *Corresponding Author: Tel. 031-652-5526, E-mail: yskim0907@hanmail.net PC-26 다양한농도의사과, 감자및바나나추출물처리가형질전환팔레놉시스원괴체유사체생장및증식에미치는영향 노희선 *, 박선경, 김종보 충청북도충주시단월동건국대학교의료생명대학생명공학과 팔레놉시스는최근심비디움과더불어주요수출화훼작물로자리잡고있으며, 국내화훼시장에서중요성이증대되고소비자들로부터많은인기를받고있는실정이다. 이에반해국내팔레놉시스우량묘생산체계는대만, 네덜란드및일본등난생산선진국들과비교해서변이발생및우량형질유지측면에서부족한점이많으며최근화훼류신품종육성에많이도입되고있는식물형질전환기술을이용한사례도국내에는거의없는실정이다. 본연구는노화지연유전자가삽입된팔레놉시스형질전환식물체의원괴체유사체 (PLB: protocorm-like bodies) 의증식및신초재분화에있어서다양한천연산물처리가어떠한효과를나타내는지구명하고자실시하였다. 팔레놉시스조직배양및형질전환유래식물체들은 banana powder, apple powder 및 potato powder 이 3 가지천연산물들을 VW 배지에 1, 5, 10, 20, 30, 40 그리고 50 g/l 농도로각각첨가하여생체중측정및신초분화효율을측정하여최적의형질전환팔레놉시스 PLB 대량증식체계를확립하고자하였다. 그결과 apple powder 30 g/l 및 banana powder 40 g/l 을혼용한처리구에서 PLB 생체중이대조구대비 2.2 배이상증가하여처리구중가장좋은결과를보였으며, 또한 PLB 로부터신초발생율도 80-85% 의고효율을나타내었다. 그리고 PLB 조직의갈변율도 3% 미만으로양호한결과를보여주었다. 또한이두천연산물의조합은형질전환팔레놉시스 PLB 뿐만아니라조직배양유래팔레놉시스 PLB 생장과증식에도유사한효과를나타내었다. 이러한천연산물의적절한첨가는향후형질전환팔레놉시스식물체대량증식체계확립에기여할수있을것이다. * 주저자 : Tel. 043-840-3549, E-mail: jbhee1011@kku.ac.kr - 145 -
PC-27 A highly sensitive real-time PCR systems for detecting rice grain-derived food ingredients in commercial mixed-flour Products Ju-Hee Kim, Sun-Goo Hwang, Cheol Seong Jang * Plant Genomics Lab., Department of Applied Plant Sciences, Kangwon National University, Chuncheon 200-713, Republic of Korea Recently, the increased consumption of mixed-grain flour products have led to improved human health in busy modern life. For this reason, the verification of commercial food authenticity is one of important subjects. The development of DNA techniques such as real-time PCR has led to the increasing efficiency of illegal food product detection. Here, we have developed a comprehensive method for detecting the grain flour of various rice cultivars in commercial food products derived from different plant species. In the genetic variation analysis of different protein coding genes on various chloroplast genomes, we found the high numbers of segregating sites in rpob and rpoc2 more than in other genes. Thus, we have attempted to develop chloroplast DNA (cpdna) markers, which were Os_m_rpoB in rpob, and Os_m1_rpoC2 and Os_m2_rpoC2 in rpoc2. To assess the applicability of three cpdna markers, we have identified the appropriate statistical measurements of each marker in various mixed-grain flour samples derived from rice cultivars and different plant species by real-time PCR, In addition, the three cpdna markers successfully applied for detecting of nonexistent rice flour in different commercial food products. *Corresponding Author: Tel. 033-250-6416, E-mail: csjang@kangwon.ac.kr PC-28 Profilings of differentially expressed genes with space environments exposed Brachypodium seeds Jin-Baek Kim *, Min Jeong Hong, Young Ha Yoon, Dong Sub Kim, Sang Hoon Kim, Joon-Woo Ahn, Yeong Deuk Jo, Si-Yong Kang Advanced Radiation Technology Institute, Korea Atomic Energy Research Institute, 29 Geumgu, Jeongeup, Jeonbuk 580-185, Korea Space has many distinguishable characteristics from earth such as strong cosmic radiation, microgravity, supervaccum and weak magnetic field. For this reason, space environments can be used an efficient mutagen for plant breeding nowadays. To identify the affected genes by condition in space with outer space, Brachypodium seeds were placed in the Russia Segment (RS) Biorisk module of International Space Station (ISS). Brachypodium distachyon is a model system for temperature grass, because they represent the characteristics for annual winter grass. Seeds and organs of plants carried by satellite or spacecraft to space can be genetically mutated by exposing space environment. We performed a duplicated RNA sequencing to profile the differentially expressed genes. As a results, about 700 genes were upregulated and 250 genes were downregulated by cosmic environments, respectively. In the molecular function category, protein kinase and transcription activity related genes were upregulated. Among the many transcription factors (TFs), stress related TFs such as ERF, NAC and WRKY were differentially expressed in space exposed samples. In the future, their expression will be identified by using qrt_pcr. *Corresponding Author: Tel. 063-570-3313, E-mail: jbkim74@kaeri.re.kr - 146 -
PC-29 Complete chloroplast genome of Codonopsis lanceolata and Platycodon grandiflorus: insight into evolution of the Asterales and development of molecular marker. Jin-hyuk Kim, Sun-Goo Hwang, Cheol-Seong Jang * Plant Genomics Lab, Department of Applied Plant Sciences, Kangwon National University, Chuncheon 200-713, Republic of Korea Asterales are dicotyledonous flowering plants and are one of the Asterid clade, incuding many species as well as Codonopsis and Platycodon. Here, we have determined the complete chloroplast genome sequences of C. lanceolata and P. grandiflorus by using the targeted denovo assembly method of short reads derived from whole genome resequencing. The total lengths of each chloroplast genome sequence are 156,180 bp for C. lanceolata and 155,453 bp for P. grandiflorus. In their chloroplast genomes, 106 genes (75 protein-coding genes, 4 rrna genes, 23 trna genes, and 4 hypothetical chloroplast open reading frames [ycfs]) exhibited the relatively similar positions. Also, 7 protein-coding genes commonly showed to contain introns in both C. lanceolata and P. grandiflorus chloroplast genome, while psaa gene contain intragenic regions only in P. grandiflorus chloroplast genome. In further analysis, we identified the codon usage bias to A or T and found the different simple sequence repeat (SSR) loci of each chloroplast genome (18 SSR loci of C. lanceolata and 16 SSR loci of P. grandiflorus). In the phylogenetic trees based on 72 protein-coding genes, C. lanceolata is more closely related to P. grandiflorus than the other plant species order Asterales. Also, we found the highest sequence diversities of 12 protein-coding genes in small single copy (SSC) region than in the inverted repeat (IRs) and large single copy (LSC) region, and 3 genes such as rpoc2 (LSC region), ndhb (IRs region), and ndhf (SSC region) showed the highest number of segregating sites in each region. Additionally, we developed the molecular markers for phylogenetic applications of C. lanceolata and P. grandiflorus chloroplast genome. *Corresponding Author: Tel. 033-250-6416, E-mail: csjang@kangwon.ac.kr PC-30 MAB SNP marker development to accelerate the breeding of Chinese cabbage Jinhee Kim *, Do-Sun Kim, Hye-Eun Lee, Yul-Kyun Ahn, Jeong Ho Kim Vegetable Research Division, National Institute of Horticultural and Herbal Science, RDA, 100, Nongsaengmyeong-ro, Iseo-myeon, Wanju-gun, Jeollabuk-do, Korea The goal of marker-assisted backcrossing is to reduce the number of generations significantly by using genome-based molecular markers. Among other types of molecular markers, SNP (single nucleotide polymorphism) is mostly used in genetic diversity analysis due to its abundance. To develop high-throughput SNP marker for MAB system, we selected 20 Chinese cabbage lines each represent traits as inner leaf color, disease resistance, head type and maturity etc. Then, we sequenced the transcriptomes of 20 lines by using Illumina Hiseq2000. The average transcriptome size was 1.37 Gbase, and the average of short reads mapping rate was about 62.15% (30xcoverage). We identified 13,976 SSR markers and 380,198 SNPs by aligning contigs of 20 Chinese cabbage lines. To develop SNP marker set, we chose 409 SNPs that covers the whole Brassica rapa transcriptome. The filtering criteria were depth, polymorphism, segregation ratio, lack of adjacent SNP and copy number. We positioned the selected SNP markers to the Chinese cabbage linkage map. Clustering dendrogram was produced using SNP marker and three different clusters were generated. The result showed that the genotyping data is partially linked to the phenotyping data. We assume that the developed SNP marker set can be applied in the Chinese cabbage MAB system soon. - 147 -
PC-31 CSGM Designer: a convenient platform for designing cross-species intron-spanning genic markers Jin-Hyun Kim 1, Chaeyoung Lee 1, Joo-Seok Park 2, Douglas R.

An important class of genetic markers is those based on orthologous genes, because they can guide hypotheses about conserved gene function. For under-studied species a key bottleneck in gene-based marker development is the need to develop molecular tools that reliably access genes with orthology to the genomes of well-characterized reference species. Here we report an efficient platform for designing cross-species gene-derived markers in legumes. The automated platform, named CSGM Designer (URL: http://tgil.donga.ac.kr/csgmdesigner), facilitates rapid and systematic design of cross-species genic markers. The underlying database is composed of genome data from five legume species whose genomes are substantially characterized. Use of CSGM designer is enhanced by graphical displays of query results, which we describe as circular viewer and search-within-results functions. CSGM platform provides a virtual PCR representation, called eht-pcr, that predicts the specificity of each primer pair simultaneously in multiple genomes. CSGM Designer output was experimentally validated for the amplification of orthologous genes using 16 genotypes representing 12 crop and model legume species, distributed among the galegoid and phaseoloid clades. Successful cross-species amplification was obtained for 85.3% of PCR primer combinations. CSGM Designer spans the divide between well-characterized crop and model legume species and their less well-characterized relatives. The outcome is PCR primers that target highly conserved genes for polymorphism discovery, enabling functional inferences and ultimately facilitating trait-associated molecular breeding. *Corresponding Author: Tel. 051-200-7508, E-mail: hkchoi@dau.ac.kr - 148 -

Severe losses of rice production was caused by various environmental conditions such as cold, heat and flooding annually. Rice is a highly sensitive to low temperature below 15-20 because of originating from tropical or subtropical climates. Especially, seedling of rice is easily damaged to low temperature and result in seedling yellowing, growth retardation, reduced tillering and yield losses at last. We used a recombinant inbreeding lines (RIL) population of 384 individuals derived from a cross between Hanareum 2, a highly cold sensitive variety and Unkwang, a cold tolerant variety for molecular mapping of QTLs related to cold tolerance. Seedling discoloration of each lines and parents caused by cold response were investigated in field condition after transplanting. And leaf samples of RIL population were collected for evaluation of chlorophyll content using 80% acetone extraction. The seedling of each lines and parents was subjected to low temperate by 5~13 during 14 days. The cold recovery score (CRS) of RILs was recorded after 4 days recovery period according to standard evaluation system (SES, IRRI). Total of eight QTLs were detected on chromosome 1, 7, 8, 10, 11 and 12 using cold tolerance traits, chlorophyll content, seedling discoloration and cold recovery score in 384 RILs. The qcrs12, which detected on chromosome 12 between two flanking markers id12002113, id12002563 (1.1 Mbp) showed 25 LOD score with 26% of phenotypic variation of cold recovery score in RILs population. The positive allele contributing to cold tolerance came from the cold tolerant parent Unkwang. The result may provide useful information for a marker-assisted breeding program to improve cold tolerant in rice. *Corresponding Author: Tel. 055-350-1185, E-mail: jacob1223@korea.kr - 149 -

In previous study, we obtained 60x coverage of sequence from Milyang23 and Gihobyeo on average comparing with Nipponbare reference genome. Also, we developed new derived cleaved amplified polymorphic sequence(dcaps) markers based on the single nucleotide polymorphisms(snps) in coding region sequence(cds) between these varieties. Totally, 1,726,798 SNPs between Milyang23 and Gihobyeo were detected. Among them, 146 SNP were selected for making dcaps markers and located on genetic map with previously reported 219 PCR-based DNA markers. The map was applied to the detection of quantitative trait loci(qtls) for stem internode diameters, culm length and panicle length within MGRIL population, and six QTLs with relatively high LOD score were found at three chromosomes; culm length and stem diameter including the first internode diameter, third and fourth internode diameter. This study showed that the NGS allowed the rapid discovery of a large number of SNPs for dcaps marker. So, we tried to find out more single nucleotide polymorphisms(snps) which were located on the whole genome sequence, such as un-translated region(utr), intron, Inter-region and coding region sequence(cds) between Milyang23 and Gihobyeo varieties. And we collected phenotypic information about culm length, panicle length, four stem internode diameters and panicle number in rice MGRIL population for QTLs. Furthermore, results of QTL analysis described above will shows relevance of molecular markers in mapping genes for useful breeding. - 150 -

Ramie leaves also have been traditionally used as a major ingredient of a type of rice cake called Song-pyun in the Southwest area of Korea, especially Yeong-Gwang province. Despite its economic importance, the molecular genetics of ramie have not been studied in detail yet. Genetic resources of ramie were widely collected from domestic local sites by Bioenergy Crop Research Center (RDA) and Yeong-Gwang Agricultural Technology Center. For the systematic and efficient management of the genetic resources, we developed SSR (simple sequence repeat) markers of ramie. To do this, we generated microsatellite-enriched genomic DNA libraries using magnetic bead hybridization selection method. 247 non-redundant contigs containing SSR motif were generated using nucleotide sequences of 376 clones from the libraries. Primer sets were designed from the flanking sequences of the repeat motif. Finally, we selected 10 SSR markers, possibly showing polymorphism among the genetic resources. Results on the genotype analysis of the ramie genetic resources using the SSR markers will be presented.

PC-35 Functional analysis of a stress-related gene BrTSR53 conferred salt tolerance in Yeast A-Ram Kim, Hyemin Lim, Hyun-Ju Hwang, Sung Han Park, Chang-Kug Kim, Hyeonso Ji, Jung-Il Cho, Soo-Chul Park, Gang-Seob Lee * National Academy of Agricultural Science, Rural Development Administration, Jeonju, Jeonlado, Korea Crops are exposed to various environmental stresses. These have been affecting the growth of crops, resulting in the severe loss of agronomic production in many countries. Therefore, development of new varieties of resistant crops is required to assure the desired productivity of crops in stress conditions. In this study, a putatively stress-related gene BrTSR53 was isolated from Brassica rapa. The BrTSR53 is 481 bp long and contains ORF region of 234 bp. The expression of BrTSR53 was determined by quantitative real-time PCR analysis. After 3 hr, the highest quantities of mrna were revealed in cold and salt stress treatments. In drought stress treatments, there was the highest expression after 36 hr. Therefore, it was confirmed that the ORF in BrTSR53 should be a gene that confer increased resistance to B. rapa growing in different stress conditions. The ORF region of BrTSR53 gene was cloned into an expression vector, pyes-dest52, and a new protein with molecular weight of 13 kda was detected by western blot analysis. Also, stress tolerance tests showed that BrTSR53-ORF transgenic yeast exhibited increased resistance to the salt stresses compared with the control. In conclusion, the present data predicts that novel ORF in BrTSR53 can serve as an important genetic resource for abiotic stress resistance. *Corresponding Author: Tel. 031-299-1656, E-mail: kangslee@korea.kr - 152 -
PC-36 A conserved oligomeric Golgi complex component-related protein is essential for pollen development in Arabidopsis Tien Dung Nguyen, Binbin Li, Sung Aeong Oh, Soon Ki Park * School of Applied Biosciences, Kyungpook National University, Korea To identify genes that play critical roles during male gametogenesis in Arabidopsis, we have isolated several pollen morphological mutants from a mutagenized seed pool generated with a T-DNA activation vector. In this study, we have focused on a mutant plant producing ~50% abnormal pollen grains including high levels of collapsed pollen at maturity. The pollen developmental analysis showed that the mutant pollen phenotype was first observed at tricellular stage. Interestingly, the mutation was only maintained as a heterozygote due to the severely reduced genetic transmission through both sexes. TAIL PCR analysis led to the identification of the responsible gene which encodes a conserved oligomeric golgi complex component-related protein (COGCC). RT-PCR analysis showed predominant expression of the gene in reproductive organs including developing spores. The gene identity was confirmed by the result that mutant plants harboring a T-DNA containing corresponding wild type gene produced less level of mutant pollen grains. Furthermore, confocal laser scanning microscopy using mature pollen expressing COGCC-RFP driven under the native promoter showed small punctate signals, which are likely to be from the Golgi complex. Further experiments for co-localization of the COGCC-RFP with the Golgi markers are underway. *Corresponding Author: Tel. 053-950-7751, E-mail: psk@knu.ac.kr - 153 -
PC-37 Identification of microspore-active promoters using transgenic rice and Arabidopsis Tien Dung Nguyen 1, Moe Moe Oo 1, Sung Aeong Oh 1, Thi Hoai Thuong Nguyen 1, Hyo-Jin Park 1, Jong Tae Song 1, Moon-Soo Soh 2, Ki-Hong Jung 3, Soon Ki Park 1* 1 School of Applied Biosciences, Kyungpook National University, Korea. 2 Department of Molecular Biology, Sejong University, Korea. 3 Department of Plant Molecular Systems Biotechnology & Crop Biotech Institute, Kyung Hee University, Korea. We recently reported rice promoters that are active in late stages of pollen development. However, rice promoters that allow manipulation of gene expression at earlier stages of pollen development are still very limited to date. In this study, we have chosen 10 putative microspore promoters, OsMSP1 through OsMSP10, based on publicly available transcriptomic datasets in rice (Oryza sativa L.). Sequence analysis of these promoter regions revealed some cis regulatory elements involved in pollen-specific expression. We also examined promoter activities using the promoter-gus reporter constructs in both transgenic rice and Arabidopsis. In rice, all of the 10 promoters directed GUS signals from the microspore stage throughout the all stages of pollen development. In addition, while GUS signals from 4 promoters, OsMSP2, OsMSP7, OsMSP9 and OsMSP10, seem to be expressed preferentially during pollen development, those from other six promoters were observed in vegetative tissues such as leaves, stems, and roots of seedlings. Similarly, in Arabidopsis, all of the 10 promoters directed GUS signals during pollen development. In detail, 8 promoters, OsMSP1 ~ OsMSP8 directed GUS signals from the microspore stage, whereas 2 promoters, OsMSP9 and OsMSP10, exhibited GUS signals from tricellular stage. Furthermore, seven promoters, except for OsMSP1, OsMSP2 and OsMSP10, showed GUS signals in shoot apical region or root tissues of seedlings. Furthermore, we verified microspore activity of four promoters, OsMSP1, OsMSP2, OsMSP3 and OsMSP6, by complementation analysis of the sidecar pollen (scp) mutant which displays microspore-specific defects. Currently, further analyses are underway for GUS expression of T 2 generation in transgenic rice and scp complementation with remaining promoters. *Corresponding Author: Tel. 053-950-7751, E-mail: psk@knu.ac.kr - 154 -
PC-38 Development of Multiplex PCR for Species-Specific Identification of the Poaceae family Based on chloroplast rpoc2 genes Jun-Cheol Moon 1,2, Ju-Hee Kim 1, Cheol Seong Jang 1* 1 Plant Genomics Lab., Department of Applied Plant Sciences, Kangwon National University, Chuncheon 200-713, Republic of Korea 2 Agriculture and Life Sciences Research Institute, Kangwon National University, Chuncheon 200-713, Republic of Korea In this study, we report that the development of a multiplex PCR method using species-specific primers for the simultaneous detection of Poaceae family members, including adlay, barley, maize, rice and wheat, based on the sequence polymorphism of the DNA-directed RNA polymerase beta'' chain (rpoc2) genes Species-specific primers were constructed with common forward primer and each reverse primers which have differences on the basis of sequences. Each primer pairs could amplify PCR products of 443 bp for rice, 346 bp for barley, 278 bp for adlay, 221 bp for wheat and 96 for maize, respectively, from the five chloroplast DNAs. The series of template DNA concentrations were identified by the sensitivity of multiplex PCR. The band of products were clearly amplified from the DNA concentration range of 0.01 to 10 ng/μl. In addition, the species-specific primers were examined for the detection of seven commercial flour mixed products. The combination of the sensitivity of a multiplex PCR with the specificity of the primers for the detection of species would allow to be applied in analyses of processed foods. *Corresponding Author: Tel. 033-250-6416, E-mail: csjang@kangwon.ac.kr - 155 -
PC-39 Development of marker-free transgenic rice expressing wheat storage protein, TaGlu-Ax1, for increasing quality processing of bread and noodle Soo-Kwon Park, So-Hyeon Baek, Dool-Yi Kim, Myoung-Ryoul Park, Na-Ra Lee, Kyoung Soon Shin, Su-Kyoung Jeon, Eun-Jae Kim, Sun-Lim Kim, Jung-Kyoung Moon * National Institute of Crop Science (NICS), Wanju-gun, Jeollabuk-do, 565-851, Korea Rice flour is used in many food products. However, dough made from rice lacks extensibility and elasticity, whereas that of wheat is suitable for many food products including breads. We have produced marker-free transgenic rice plants containing a wheat TaGlu-Ax1 gene encoding the HMG-GS from the Korean wheat cultivar Jokyeong using the Agrobacteriummediated co-transformation method. The TaGlu-Bx7-own promoter was inserted into a binary vector for seed-specific expression of the TaGlu-Ax1 gene. Two expression cassettes comprised of separate DNA fragments containing only TaGlu-Ax1 and hygromycin phosphotransferase II (HPTII) resistance genes were introduced separately to the Agrobacterium tumefaciens EHA105 strain for co-infection. Each EHA105 strain harboring TaGlu-Ax1 or HPTII was infected to rice calli at a 3:1 ratio of TaGlu-Ax1 and HPTII, respectively. Then, among 210 hygromycin-resistant T 0 plants, we obtained 20 transgenic lines with both TaGlu-Ax1 and HPTII genes inserted into the rice genome. We reconfirmed integration of the TaGlu-Ax1 gene into the rice genome by Southern blot analysis. Transcripts and proteins of the wheat TaGlu-Ax1 were stably expressed in the rice T 1 seeds. Finally, the marker-free plants harboring only the TaGlu-Ax1 gene were successfully screened at the T 1 generation. *Corresponding Author: Tel. +82-63-238-53214, E-mail: moonjk@rda.go.kr - 156 -
PC-40 Delimitation of Genomic Location for Frl locus Conferring Resistance to Fusarium Crown Root Rot in Tomato Bichsaem Kim 1, Jihyun Hwang 1, Joon Young Kim 2, Byung Sup Kim 2, Sung Ran Min 3, Huijung Jung 4, Ill-Sup Nou 4, Younghoon Park 1 1 Department of Horticultural Bioscience, Pusan National University, Miryang, Korea 2 Department of Plant Science, Gangneung-Wonju National University, Gangneung, Korea 3 Plant Systems Engineering Research Center, Korea Research Institute of Bioscience and Biotechnology (KRIBB), Daejeon, Korea 4 Department of Horticulture, Sunchon National University, Sunchon, Korea Fusarium crown root rot (FCRR) is a severe fungal disease caused by Fusarium oxysporum f. sp. radicis-lycopersici (FORL) in tomato. Resistance to FORL is conferred by single dominant locus Frl on chromosome 9, but its precise genomic location is not clearly determined. In this study, detailed location of Frl was assessed by using a set of molecular markers physically anchored on Chr.9 and F 2 and RIL population derived from FORL-resistant inbred AV107-4 (S.lycopersicum) x susceptible L3708 (S. pimpinellifolium). Bioassay of the two populations with a FORL strain isolated from Korea resulted in single dominant heritance of the resistance. Two SCAR and 11 CAPS markers encompassing 3.6Mb~72Mb of Chr.9 were developed from the Tomato-EXPEN 2000 map and SolCAP SNP-array analysis. These markers were genotyped on 345 F 2 plants. A high level of cosegregation with the resistance were observed for 5 markers which were mapped at a large physical interval of 5.1Mb (T1212) to 46.4Mb (SSR237), indicating that genetic recombination was highly suppressed in this region. Cosegregation of these markers with Frl was confirmed by using 126 RILs. The results implied that, in contrast with the previously reported long arm, Frl is present on a pericentromeric region of short arm of Chr. 9, in which crossing-over is severely suppressed. The marker set was further tested on 12 FORL-resistance or susceptibility commercial cultivars. Unlike the biparental populations, frequent linkage break was observed for T1212 and D4 in commercial cultivars. T1212 and D4 showed 50% and 100% match with the phenotype, respectively. D4, a CAPS, was converted to a high resolution melting (HRM) marker and tested on 55 breeding lines from private seed companies (Fig.3). All breeding lines showed the HRM genotype for resistance allele, indicating that D4 can be useful for selecting FORL-resistance tomato plants.

However, one to one orthologous genes allows only for the analysis due to methodological limitation. A number of genes have in-paralogs as a result of gene expansion in crops. Here, we report a new approach for detecting accelerated evolution, which includes in-paralogs as well as one to one orthologs. This new approach can detect many novel accelerated genes among rice in-paralogs, which have not been investigated yet. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 157 -

Zinc is one of the most important essential micronutrient for human About thirty percentage world s population doesn t still get enough zinc through their diets. As a staple food of over half world s population, rice should take the responsibility to provide much more zinc in the future. We analyzed the transcriptome profiles for rice grain from high zinc content and low zinc content lines at the early milky stage using the Illumina Sequencing method. The analysis results for the sequencing data indicated that many transcripts showed different expressions between high zinc content and low zinc content in early milky stage of rice and RT-qPCR analyses confirmed the expression patterns of selected transcripts. Functional analysis of the differentially expressed transcripts indicated that genes have functional annotation and their functions are mainly involved in oxidation-reduction, metabolic, transport, transcript regulation, defense response and photosynthetic processes. Based on the functional annotation of the differentially expressed genes, the possible process that regulates these differentially expressed transcripts in rice grain responding to Zinc at the early milky stage was further analyzed. The functional classification of those genes indicated their connection with various metabolic pathways, Zinc transport, signal transduction, transcriptional regulation, and other processes related to growth and development in early milky stage of rice. Using Illumina sequencing technology, the differences between the transcriptomes of high zinc content and low zinc content lines the early milky stage was described here for the first time. The candidate transcripts may provide genetic resources that may be useful in the improvement of Zinc concentration of rice. The model proposed here is based on differences in expression and transcription between two rice lines. In addition, the model may support future studies on the molecular mechanisms underlying plant responses to Zinc. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 158 -

In the present study, we scanned BADHs sequences of 295 rice cultivars, and 10 wild rice accessions to determine the polymorphisms, gene functions and domestication of these two genes. A total of 16 alleles for BADH1 and 10 alleles for BADH2 were detected in transcription region of cultivars and wild species. Association study showed that BADH1 has significant correlation with salt tolerance in rice during germination stage, the SNP P1 1483 (T/A)ishighlycorrelatedwithsalttoleranceindex(STI)(P<10-4 ). While, BADH2 was only responsible for rice fragrance, of which two BADH2 alleles (P2 3036, P2 5390 ) explain 97% of aroma variation in our germplasm. It indicated that there are no overlapping functions between the two homology genes. In addition, a large LD block was detected in BADH2 region, however, no large LD blocks in a 4-Mb region of BADH1. Only BADH2 region shown significant bias Tajima s D value from the balance. Extended haplotype homozygosity study revealed fragrant accessions had a large LD block that extended around the mutation site (P2 3036 ) of BADH2, while both of the BADH1 alleles (SNP P1 1483 (T/A)) did not show large extended LDblock. All these results suggested that BADH2 was identified as a domesticated gene during rice evolution, while BADH1 was not selected by human beings. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 159 -
PC-44 Discovery of a novel fragrant allele and development of functional markers for fragrance in rice Qiang He 1, Yong-Jin Park 1,2* 1 Department of Plant Resources, College of Industrial Sciences, Kongju National University, Yesan 340-702, Republic of Korea 2 Legume Bio-Resource Center of Green Manure (LBRCGM), Kongju National University, Yesan 340-702, Republic of Korea Aroma in rice (Oryza sativa L.) results from the loss of function of the betaine aldehyde dehydrogenase (Badh2) gene on chromosome 8. An 8-bp deletion in exon 7 of Badh2 was reported to be the main allele functionally associated with fragrance. The discovery of new functional alleles will provide additional genetic resources to improve fragrant rice. In this study, we sequenced the Badh2 gene in 30 rice accessions and filtered the Badh2 polymorphisms from whole genome re-sequence data of 295 rice accessions. Seven alleles were detected from the sequence data. Six of the seven were known alleles and one was a novel allele (badh2-e12). The novel allele was a 3-bp deletion in exon 12. Five functional markers, targeting six of the seven alleles, were identified. Fourteen accessions were selected to test the utility of these markers. The five molecular markers reliably distinguishing this fragrant rice from other fragrant or non-fragrant rice accessions. Analysis of two F2 rice population validated the genetic markers FME12-3 and FME14I as functional markers. These two markers co-segregated with the fragrance phenotype. These markers will be used in a Badh2 diversity study and to breed improved fragrant rice accessions via marker-assisted selection. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 160 -
PC-45 Orthologous based study to detect the fast evolutionary genes related to rice pre-harvest sprouting Wei Tong 1, Tae-Sung Kim 1,2, Kyu-Won Kim 1,2, Yong-Jin Park 1,2* 1 Department of Plant Resources, College of Industrial Sciences, Kongju National University, Yesan 340-702, Republic of Korea 2 Legume Bio-Resource Center of Green Manure (LBRCGM), Kongju National University, Yesan 340-702, Republic of Korea Pre-harvest sprouting (PHS) results in lower yields for rice and other crops, especially in rainy season before harvest. By using gene based functional studies to reveal the mechanism of PHS related pathways can be a good way in breeding for more PHS resistant accessions. Orthologous genes, which are homologous genes that diverged after a speciation event, generally maintain a similar function in different species to that of the ancestral gene in which they evolved from. Applied with a McDonald-Kreitman Test (MKT), we examined more than 10,000 orthologous genes between rice (Oryza sativa) and Brachypodium (outgroup) based on different phenotypic groups in order to find some fast evolutionary genes in rice PHS. Three groups which represented the PHS susceptible (group 1), PHS medium (group 2) and PHS resistant (group 3) were separated based on the phenotype and each group was examined with the outgroup for MKT. Total 60 fast evolutionary genes that have a positive selection with FDR 0.05 were found in the three groups, and 19, 5 and 8 genes were specific existed in group 1, 2 and 3, respectively. Annotation of these genes were conducted and the predicted functions were investigated, leading that one Ethylene receptor-like gene that may related to PHS based on the previous studies, which need to be validated later, however. In addition, network analysis of these characterized genes were also investigated, which could reveal the connection of genes between each other. Moreover, the association study between the candidate gene ethylene receptor and the PHS phenotype was performed and indicated that this gene is significantly correlated with PHS in rice. All these above indicated that with this orthologous based method, we can find some important candidate genes that may play an important role in some traits. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 161 -

Here, we constructed a chloroplast variation map of 30 landrace rice strains of Korean origin, using the Oryza rufipogon chloroplast genome (Genbank: NC_017835) as a reference. Differential distribution of single nucleotide polymorphisms (SNPs) and indels across the rice chloroplast genome is suggestive of a region-specific variation. Population structure clustering revealed the existence of two clear subgroups (indica and japonica) and an admixture group (aus). Phylogenetic analysis of the 30 landrace rice strains and six rice chloroplast references suggested and supported independent evolution of O. sativa indica and japonica. Interestingly, two aus type accessions, which were thought to be indica type, shared a closer relationship with the japonica type. One hypothesis is that Korean aus was intentionally introduced and may have obtained japonica chloroplasts during cultivation. We also calculated the nucleotide diversity of 30 accessions and compared to six rice chloroplast references, which shown a higher diversity in the indica and aus groups than in the japonica group in lower level substitution diversity. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 162 -

More than 2 billion people face Fe deficiency. Rice can be a potentially valuable source to supplement that mineral since it is staple food for two-thirds of the world s population. To bring the nutritional level of the milled product up to that of the whole grain (brown), rice should be enriched with thiamin, niacin and iron. Also iron has important role that absorption from the photosynthetic cells proceeds, chlorophyll synthesis and the growth process of the plant.

Development of genetic basis of high salt-tolerant rice is necessary to satisfy urgent needs in rice breeding. In this study, 295 rice accessions from a Korean authentic core set were used to identify the evolution associated genes regarding salt tolerance. By using McDonald-Kreitman Test (MKT), we detected orthologous genes in rice (Oryza sativa) using Brachypodium as an outgroup to investigate fast evolved genes that express differentially based on distinct phenotypic groups. Three groups which represented the salt sensitive (group 1), salt medium tolerant (group 2) and salt tolerant (group 3) were separated and each group was examined with the outgroup in neutral and non-neutral polymorphism together with the divergence levels. Total 53 fast evolutionary genes that have a positive selection with FDR 0.05 were found in the three groups. Among them, 15, 31 and 7 genes were included exclusively in group 1, 2 and 3, respectively. Annotation of these genes showing the predicted functions were checked. Two genes were found to be related to high salt tolerance based on the previous studies. Besides, association study of the candidate gene alleles and salt tolerance phenotype was carried out, indicating that these genes were correlated with salt tolerance. All these result support that using this type of evolution study, we may find some important candidate genes which are related to important traits in rice, such as the salt tolerance, providing important information for future gene based molecular breeding and functional analysis in rice. *Corresponding Author: Tel. 041-330-1201, E-mail: yjpark@kongju.ac.kr - 165 -

TaqMan copy number assay was determined inserted T-DNA copy number. Also flanking sequence tags (FSTs) analysis was isolated from 203 single copy T-DNA lines of transgenic plants and sequence mapped to the rice chromosomes. In analyzing single copy lines, we identified 157 flanking sequence tags (FSTs), among which 58 (36%) were integrated into genic regions and 97 (62%) into intergenic regions. About 27 putative homozygous lines were obtained through multi-generations of planting, resistance screening and TaqMan copy number assay. To investigate the transgene expression patterns, quantitative real-time PCR analysis was performed using total RNAs from leaf tissue of single copy, intergenic region of T-DNA insertion and homozygous T2 plants. The mrna expression levels of the examined transgenic rice were significantly increased in all of the transgenic plants. In addition, myc-tagged 35S:BrTSR15 and 35S:BrTSR53 transgenic plants were displayed higher levels of transgene protein.

PC-54 Molecular dissection of a rice RING finger protein induced by salt and drought treatments Yong Chan Park, Cheol Seong Jang * Plant Genomics Lab. Department of Applied Plant Sciences, Kangwon National University, Chuncheon 200-713, Korea As sessile organisms, plants have evolved mechanisms that allow them to adapt and survive periods of various environmental stresses including high salinity and drought. The ubiquitin-proteasome system (UPS) is an integral player in plant response and adaptation to various abiotic stresses. Understanding UPS function has centered mainly on defining the role of E3 ubiquitin ligases, which are the substrate-recruiting component of the ubiquitination pathway. Here, we report on Ring finger E3 ligase, Oryza sativa salt- and drought-induced RING finger protein1 gene (OsSDRFP1) in defense responses to osmotic stresses. Results of qrt-pcr and In vitro ubiquitination assay demonstrated that OsSDRFP1 act as an E3 ligase in response to salt and drought stresses. in this study, Subcellular localizations showed that the OsSDRFP1 was observed in cytosol (66%) and nucleus (34%) under non-treated conditions. However, the florescence signals of rice protoplasts after salt treatments detected in nucleus (60%) higher than in cytosol (30%). The Arabidopsis plants overexpressing OsSDRFP1 clearly exhibited hypersensitive responses to salt stress. whereas, OsSDRFP1-overexpressing plants were more tolerant to both drought- and ABA-stresses than the wild-type plants. These results might suggest that OsSDRFP1 has a dual function as a regulator of high salt- and drought-stresses.

To provide a genomic resource as a reference genome for the Cucurbitaceae crop improvement, we performed whole genome sequencing of Korean landrace, Gotgam chamoe. We used Illumina HiSeq2000 sequencing platform to generate 89 Gb (205X) of paired and mate pair sequence reads. The pre-processed reads were de novo assembled resulting in 4,764 scaffolds with a N50 scaffold length of 249kb. This assembly represented 379.8Mb which was 84.7% of the 448Mb of the whole genome. The assembled draft was predicted 26,634 genes of which 80% were predicted by known protein or C. melo unigene homology. Approximately 20% of predicted genes were hypothetical. A total of 1,885 non-coding RNA was detected including rrna. The transposable elements were accounted for 21% (71.6Mb) of the total assembly. All the marker candidates including SSR, INDEL, SNP were mined and presented. The draft genome will provide a useful platform for genomic research and improvement for Cucurbitacea crops. *Corresponding Author: Tel. 042-860-4345, E-mail: kimhr@kribb.re.kr - 168 -
PC-56 Profile of econdary metabolites and related gene expressions of Panax ginseng adventitious roots induced from 5 korean ginseng cultivars cultured in bioreactors Hyun-Seung Park 1, Dong-Kyu Lee 2, Yun Sun Lee 1, Sang-Choon Lee 1, Murukarthick Jayakodi 1, Sung Won Kwon 2, Tae-Jin Yang 1* 1 Department of Plant Science, Plant Genomics and Breeding Institute, and Research Institute for Agriculture and Life Sciences, College of Agriculture and Life Sciences, Seoul National University, Seoul, 151-921, Republic of Korea 2 College of Pharmacy, Seoul national university, Seoul Korea Panax Ginseng is a perennial medicinal plant originated from North-east asia. Because of its well-known tonic effects mainly from ginsenosides, various types of processed ginseng products have been distributed around the world. Here, we analyzed secondary metabolite profiling of adventitious roots of 5 korean ginseng cultivars, Chunpoong (CP), Sunhyang (SH), Gopoong (GO), Sunun (SU), and Cheongsun (CS). At the same time, the profiles of relative gene expressions related to ginsenoside biosynthesis pathway were compared among ginseng cultivars. Secondary metabolite profiles were revealed by UPLC/Q-TOF-MS from extracts of bioreactor derived adventitious roots of five ginseng cultivars. Using principal component analysis, secondary metabolite profiles of ginseng cultivars were categorized into three groups. Metabolites with high VIP values were annotated using known database and standards compounds. Relative gene expression of ginsenoside related gene were analyzed using realtime PCR. The three groups had distinct metabolite contents. Furthermore, gene expression profiles related to ginsenoside were also different, which might contribute diverse secondary metabolite composition of ginseng cultivars. Further integrated analysis would provide a relationship between genetic background of ginseng cultivars and secondary metabolite profiles.

PC-58 Mapping QTLs of resistance to head splitting in cabbage (Brassica oleracea L. var. capitata L.) Wenxing Pang, Xiaonan Li, Seong Ho Lee, Dasom Kim, Sang Heon Oh, Su Ryun Choi, Yong Pyo Lim * Molecular Genetics and Genomics Lab, Department of Horticulture, Chungnam National University, Daejeon 305-764, Republic of Korea. Cabbage head splitting can greatly affect both the quality and commercial value of cabbage (Brassica oleracea). To detect the genetic basis of head-splitting resistance, a genetic map was constructed using an F2 population derived by crossing 748 (head-splitting-resistant inbred line) and 747 (head-splitting-susceptible inbred line). The map spans 830.9cM and comprises 270 markers distributed in nine linkage groups, which correspond to the nine chromosomes of B. oleracea. The average distance between adjacent markers was 3.6cM. A total of six quantitative trait loci (QTLs) conferring resistance to head splittingwere detected in chromosome 2, 4, and 6. Two QTLs, SPL-2-1 and SPL-4-1, on chromosomes 2 and 4, respectively, were detected in the experiments over 2 years, suggesting that these two potential loci were important for governing the head-splitting resistance trait. Markers BRPGM0676 and BRMS137, which were tightly linked with head-splitting resistance, were detected in the conserved QTL SPL-2-1 region using bulked segregant analysis. Synteny analysis showed that SPL-2-1 was anchored to a 3.18Mb genomic region of the B. oleracea genome, homologous to crucifer ancestral karyotype E block in chromosome 1 of Arabidopsis thaliana. Moreover, using a field emission scanning electron microscope, significant differences were observed between the two parental lines in terms of cell structures. Line 747 had thinner cell wall, lower cell density, larger cell size, and anomalous cell wall structure compared with the resistant line 748. The different cell structures can provide a cytological base for assessing cabbage head splitting. *Corresponding Author: Tel. 042-821-5739, E-mail: yplim@cnu.ac.kr - 170 -
PC-59 Characterization and analysis of OsUPS, a U-box containing E3 ligase that respond to phosphate starvation in rice. Ki-Deuk Bae, Doh-Hoon Kim * Department of Genetic engineering, College of Natural Resources and Life Science, Dong-a University, Busan 604-714, Republic of Korea The ubiquitin-26s proteasome system is important in the quality control of intracellular proteins. The ubiquitin-26s proteasome system includes the E1 (ubiquitin activating), E2 (ubiquitin conjugating) and E3 (ubiquitin ligase) enzymes. U-box proteins are a derived version of RING-finger domains, which have E3 enzyme activity. Here, we present the isolation of a novel U-box protein, OsUPS, from rice (Oryza sativa).the cdna encoding the O.sativa U-box protein(osups) comprises 1338bp, with an open reading frame of 445 amino acids. The open reading frame of the OsUPS protein is comprised of notable domains: a single ~70-amino acid domain and a GKL domain that contains conserved glycine, lysine/ arginine residues and leucine-rich feature. We found that full-length expression of OsUPS was up-regulated in both rice plants and cell culture in the absence of inorganic phosphate (Pi). A self-ubiquitination assay indicated that the bacterially expressed OsUPS protein had E3 ligase activity, and subcellular localization results showed that OsUPS was located in the chloroplast. Suppression of OsUPS resulted in servre signs of toxicity caused by the over-accumulation of Pi. These results support the notion that OsUPS plays an important role in the Pi signaling pathway through the ubiquitin-26s proteasome system. *Corresponding Author: Tel. 051-200-7507, E-mail: dhkim@dau.ac.kr PC-60 Cloning and identification of the partial major ampullate silk protein gene from the spider Araneus ventricosus in rice. Ki-Deuk Bae, Doh-Hoon Kim * Department of Genetic engineering, College of Natural Resources and Life Science, Dong-a University, Busan 604-714, Republic of Korea Fibroin silk proteins from spider or silkworm are attractive biomaterials that are of particular biotechnological interest for industrial and medical purposes because of their unique physical and mechanical properties. In this study, we generated and characterized the transgenic rice plant expressing a spider silk protein. Spider silks have great potential as biomaterials with extraordinary properties. Here, we report the cloning and characterization of the major ampullate silk protein gene from the spider Araneus ventricosus. A cdna encoding the partial major ampullate silk protein (AvMaSp) was cloned from A. ventricosus. An analysis of the cdna sequence shows that AvMaSp consists of a 240 amino acid repetitive region and a 99 amino acid C-terminal non-repetitive domain. The peptide motifs that were found in the spider major ampullate silk proteins, (A)n, (GA)n, and (GGX)n, were conserved in the repetitive region of AvMaSp. Phylogenetic analysis further confirmed that AvMaSp belongs to the spider major ampullate spidroin family of proteins. Recombinant AvMaSp-R was degraded abruptly by trypsin. However, AvMaSp-R was stable at 100 C for at least 30 min. Additionally, the AvMaSp-R was stable at ph values from 2 to 12 for at least 1 h. Taken together, our findings describe the molecular structure and biochemical properties of the A. ventricosus major ampullate silk protein and demonstrate its potential as a biomaterial. *Corresponding Author: Tel. 051-200-7507, E-mail: dhkim@dau.ac.kr - 171 -
PC-61 Identification and analysis of osgasd gene. Ki-Deuk Bae, Doh-Hoon Kim * Department of Genetic engineering, College of Natural Resources and Life Science, Dong-a University, Busan 604-714, Republic of Korea We used an efficient system to create rice mutant by Ac/Ds transposon insertion mutagenesis, such as selected homozygous mutant in dwarf phenotypes. We reported here the identification of function of dwarf OsGASD gene(oryza sativa Gibberellin Acid Sensitive Dwarf). OsGASD gene encodes a 344 amino acid polypeptide and no homology proteins in Gene Bank. The osgasd mutnat was sensitive to exogenous gibberellic acid(ga) level. We performed experiment to controlled expression the OsGASD gene, its role in plant development, a quantitative analysis of endogenous GA content and sensitivity to GA. The osgasd mutant includes smaller amount of active GAs than wild-type. osgasd mutant plant of GA biosynthesis pathway causes GA deficiency and dwarf plants, and endogenous GA suppliance can restore the wild type phenotype in this mutant. There result indicated that OsGASD gene regulated the elongation of shoot, stem and plant height. The increased expression of OsGASD gene dramatically induces expression of the factors associated with GA biosynthesis, whereas osgasd mutant suppression of the factors associated with GA biosynthesis, loading to dwarf phenotypes. That applied GA3 at the plant development stage to survey the response of OsGASD gene to GA3. We suggest that OsGASD gene is related to factors of GA biosynthesis pathway regulating rice internodes development. *Corresponding Author: Tel. 051-200-7507, E-mail: dhkim@dau.ac.kr PC-62 OsMYB4p, an R2R3-type MYB transcription factor, improves phosphate uptake in rice Ki-Deuk Bae, Doh-Hoon Kim * Department of Genetic engineering, College of Natural Resources and Life Science, Dong-a University, Busan 604-714, Republic of Korea R2R3 MYB transcription factors play regulatory roles in plant responses to various environmental stresses and nutrient deficiency. In this study, we isolated MYB-like gene respond to phosphorus deprivation in rice and designated OsMYB4P, an R2R3 MYB transcription factor, from rice under low-phosphate conditions. OsMYB4P is 993bp long and encodes a 330 amino acid polypeptide. OsMYB4P was localized in the nucleus and acted as a transcriptional activator. Transcriptional levels of OsMYB4P in cell suspension, shoots, and roots of rice increased under low phosphate conditions. Shoots and roots of OsMYB4P overexpressing plants grew well in high and low phosphate conditions. In addition, root system architecture was altered considerably as a result of OsMYB4P overexpression. Under both phosphate sufficient and deficient conditions, more Pi accumulated in shoots and roots of OsMYB4P overexpressing plants than in the wild type. Overexpression of OsMYB4P led to greater expression of Pi transporter-family proteins OsPT1, OsPT2, OsPT4, OsPT7, and OsPT8 in shoots, and to decreased or unchanged expression of these proteins in roots, with the exception of OsPT8. These results demonstrate that OsMYB4P may be associated with efficient utilization of Pi in rice. *Corresponding Author: Tel. 051-200-7507, E-mail: dhkim@dau.ac.kr - 172 -
PC-63 Characterizataion and histological analysis of leaf development related gene in rice. Ki-Deuk Bae, Doh-Hoon Kim * Department of Genetic engineering, College of Natural Resources and Life Science, Dong-a University, Busan 604-714, Republic of Korea Establisment of rice library is an essential approach for rice functional genomics study. Utilizaing maize transposable element Ac/Ds is a promising method to construct insertional mutagenesis library of rice. Ac/Ds tagging system has received extensive application in rice during the past several years. The maize Ds element is one of the main tagging vehicles used in rice. Narrow leaf mutant have short height, narrow leaf width and large angle. To compare with wild type and narrow leaf mutant in detail, we observed the leaves under microscope. In specific portion(large and small vein), no significantly reduce cell size and number of cell. Knock-out of the OsNLR(narrow leaf ribokinase) gene inhibits internodes, panicles, angle(between leaf and stem), leaf, seed. OsNLR was shown to specifically expressed on leaf. In real time PCR analysis with mature leaf of wild type and mutant, there might be a functional association between OsAGO7, NRL1, NAL1 and NAL7 in regulating leaf development. We tested on the experimental field using wild type and mutant plants. In agricutural traits that contain leaf and seed related traits(except angle) significantly reduce in mutant plants. These results demonstrate that OsNLR gene may be associated with leaf development. *Corresponding Author: Tel. 051-200-7507, E-mail: dhkim@dau.ac.kr PC-64 Study of transgenic rice plants in rich expressed sheep serotonin N-Acetyltransferase Yeong Byeon, Hyoung Yool Lee, Kyoungwhan Back * Department of Biotechnology, Bioenergy Research Center, Chonnam National University, Gwangju, Republic of Korea Serotonin N-acetyltransferase (SNAT), the penultimate enzyme in melatonin biosynthesis, catalyzes the conversion of serotonin into N-acetylserotonin. Plant SNAT is localized in chloroplasts. To test SNAT localization effects on melatonin synthesis, we generated transgenic rice plants overexpressing a sheep (Ovis aries) SNAT (OaSNAT) in their chloroplasts and compared melatonin biosynthesis with that of transgenic rice plants overexpressing OaSNAT in their cytoplasm. To localize the OaSNAT in chloroplasts, we used a chloroplast targeting sequence (CTS) from tobacco protoporphyrinogen IX oxidase (PPO), which expresses in chloroplasts. The purified recombinant CTS:OaSNAT fusion protein was enzymatically functional and localized in chloroplasts as confirmed by confocal microscopic analysis. The chloroplast-targeted CTS:OaSNAT lines and cytoplasmexpressed OaSNAT lines had similarly high SNAT enzyme activities. However, after cadmium and butafenacil treatments, melatonin production in rice leaves was severalfold lower in the CTS:OaSNAT lines than in the OaSNAT lines. Notably, enhanced SNAT enzyme activity was not directly proportional to the production of N-acetylserotonin, melatonin, or 2-hydroxymelatonin, suggesting that plant SNAT has a role in the homeostatic regulation of melatonin rather than in accelerating melatonin synthesis. *Corresponding Author: Tel. 062-530-0441, E-mail: kback@chonnam.ac.kr - 173 -
PC-65 Presence of melatonin 2-hydroxylase in rice (Oryza sativa) plants Yeong Byeon, Kyoungwhan Back * Department of Biotechnology, Bioenergy Research Center, Chonnam National University, Gwangju, Republic of Korea Although melatonin biosynthetic genes from plants have been cloned, the melatonin catabolism mechanisms remain unclear. To clone the genes responsible for melatonin metabolism, we ectopically expressed 35 fulllength cdnas of rice 2-oxoglutarate-dependent dioxygenase (2-ODD) in Escherichia coli and purified the corresponding recombinant proteins. In vitro 2-ODD assays showed four independent 2-ODD proteins that were able to catalyze melatonin into 2-hydroxymelatonin, exhibiting melatonin 2-hydroxylase (M2H). These M2H proteins had peak activities at ph 8.0 and 30 C. The K m ranged from 121 µm to 371 µm with the V max ranging from 1.7 to 18.5 pkat/mg protein, respectively. The M2H enzyme activities were dependent on cofactors such as α-ketoglutarate, ascorbate, and Fe 2+, similar to the 2-ODD enzymes. M2H activity was inhibited by prohexadione-ca, an inhibitor of 2-ODD, in a dose-dependent manner. M2H activity was high in the roots of rice seedlings, concurrent with high transcription levels of 2-ODD 21, suggesting that 2-ODD 21 was a major gene for M2H activity. Analogous to the high M2H activity in the roots, 2-hydroxymelatonin was found in large quantities in roots treated with melatonin. These results suggest that melatonin was metabolized into 2-hydroxymelatonin by the M2H genes in plants, but the physiological significance of 2-hydroxymelatonin remains to be examined in the future. *Corresponding Author: Tel. 062-530-0441, E-mail: kback@chonnam.ac.kr PC-66 Production of doubled haploids through micropspore culture in F 1 hybrids of yellow sarson and turnip rape of Brassica rapa Mi-Suk Seo, Mi-Sun Moon, Kyung-gin Lee, So Youn Won, Sangho Kang, Seong-Han Sohn, Jung Sun Kim * Department of Agricultural Biotechnology, National Academy of Agricultural Science, RDA, JeonJu, 560-500, Korea Brassica rapa subspecies show morphological variability, containing vegetable types and oilseed types.

As microscope study for the different size of immature bud sections and we have known the floral meristem with already four locules in immature buds less size than 1mm of LP8. To identify of determining of tetralocular ovary formation, RNA-seq was carried out on the isolated RNA from less than 1mm and from 1mm of bud size respectively. By contrast tetralocular ovay and bilocular ovary, Chiifu is used. A total of 994 differentially expressed genes(degs) are detected in only LP8.

Plants have evolved elaborate innate immune systems against invading pathogens, such as bacteria, fungi, oomycetes, viruses and insects. Among them, intracellular immune receptors known as nucleotide-binding site and leucine-rich repeat (NB-LRR) play critical roles in effector-triggered immunity (ETI) regarding to plant defense. Here, we identified potential NB-LRR coding sequences from pepper genome using bioinformatics analysis and performed comparative analysis with Solanaceae plants. As a result, we identified 267, 443, and 755 NBS-encoding genes in the genome of tomato, potato, and pepper, respectively. These may indicate that the Solanaceae NB-LRRs were evolved through species-specific unequal-duplication event. Further phylogenetic and clustering analyses revealed that Solanaceae NB-LRRs were classified into the 14 subgroups with 1 TNL and 13 CNL types. We found that the genes in CNL-G1 and CNL-G2 subgroup were highly expanded compared to other subgroup showing a large portion of NB-LRR in pepper genome. Among 755 NB-LRRs in pepper genome, 623 were physically mapped on all 12 pepper chromosome pseudomolecules. Furthermore, a number of NB-LRRs in the same group were physically clustered by tandem array in the specific chromosome. Genome-wide identification of pepper NB-LRR family and their evolutionary analysis could provide an important resource for identification and characterization of genes for breeding of disease resistance crops. - 175 -

Ginsenosides are glycosylated triterpenes, referred to saponins, have been especially noted as active compounds contributing to the various efficacy of ginseng. In this study, we are trying to select high saponin content of ginseng lines from the gamma irradiated adventitious roots. Recently, we have generated several mutant ginseng lines improving ginseniside content by gamma radiation. The mutant lines were selected by phenotypes and ginsenoside content (HPLC analysis) of the irradiated adventitious root lines. However, the ginsenoside content of the mutant lines was not sufficient for commercial use and the selection method was not suitable for large scale of mutant line selection. In this study, we are testing Fourier transfer infrared spectroscopy (FT-IR) as a new selection method of mutant lines in Panax ginseng. About 5,000 pieces of Panax ginseng adventitious roots were exposed to gamma radiation ( 60 Co). Irradiation dosages were 0, 25, 50 and 70Gy. Survival rate of the irradiated samples was evaluated by counting the number of survival main roots after 5 weeks culture in the solid MS medium with NAA, IAA and 5% sucrose. In present, we are collecting the survived adventitious root lines (about 900 lines) from the gamma irradiated ginseng roots for FT-IR and HPLC analysis. After analysis of FT-IR and HPLC, we will assess the suitability of the FT-IR as a screening method for the preparation of mutant lines in ginseng.

Gene flow from transgenic plants to wild closely related species has raised concern recently. Since transgenic crops were released in 1996, the global area of transgenic crops has been increasing rapidly. The transgene introgression from transgenic crops to their wild relatives is unavoidable in some species. Transgene introgression is of concern because the crop wild plant hybrids might be conferred with a selection advantage to increase their performance, which could result in negative ecological consequences to natural ecosystems. The genus Brassica has 159 species, including a number of wild species that are of great importance to the economy. Most transgenic Brassica gene flow research has focused on the most successful cross between transgenic oilseed rape Brassica napus and its wild relatives Brassica rapa, a widely distributed weed in the farming system in Europe and America, since the hybridization can spontaneously happen and the generations can backcross to B. rapa easily in the wild conditions. In this study, we aimed to characterize transgene introgression, segregation, and expression in backcrossed generations between tramsgenic B. napus and B. rapa. These results will contribute to the environmental risk assessment and assist in biosafety management. *Corresponding Author: Tel. 063-238-4712, E-mail: sisohn@korea.kr PC-71 Molecular marker evaluated for heat tolerance in wheat Jae-Han Son 1*, Kyeung-Hoon Kim 2, Chon-Sik Kang 1, Young-Keun Cheong 1, Jong-Chul Park 1, Kyong-Ho Kim 1, Yang-Kil Kim 1, Young-Jin Oh 1, Jong-Ho Park 1, Tae-Hwa Song 1, Jae-Seong Choi 1, Bo-Kyeong Kim 1 1 Crop Breeding Division, National Institute of Crop Science, RDA, 565-851, Korea 2 Department of Southern Area, National Institute of Crop Science, RDA, 627-803, Korea High temperature is one of major environmental stress. Some of molecular markers related heat stress or tolerance have been reported by many researchers. Heat tolerance managing is difficult through the phenotypic selection, so marker assistant selection (MAS) using molecular markers like as RAPD, SSR ect. was tried to selection of useful traits for heat tolerance. Fourteen SSR markers reported by previous research were selected for this research. These markers were linked to important traits including grain filling duration, HIS (Heat susceptibility index) grain filling duration. In this study, we tried to evaluate 14 SSR markers for MAS using 31 useful wheat resources including 24 crossing line from Turkey and six Korean wheat cultivars using 14 SSR markers. The average of the number of alleles and PIC values in this study were 6.14 and 0.63, respectively. Two major clades and six sub clades were grouped by phylogenetic tree using UPGMA program. Six Korean wheat cultivars were distinct from other Turkey resources in the phylogenetic dendrogram.

Because of tremendous diversity and variants, maize is considered as a forefront crop development and estimation of molecular markers for agricultural trait in genetics and breeding. Using quantitative trait loci (QTL) and marker assisted breeding (MAS), molecular breeders are able to development of drought tolerance and grain yield in maize genotype. To study QTL congruency, a meta QTL analysis including results from eight-teen QTL publications for grain yield and drought tolerance were considered. Among them, we assembled 420 QTLs for abscisic acid (ABA) concentration, anthesis silking interval (ASI), days to flower, days to silk, ear number, kernel number, grain number and grain yields, involved in drought tolerance and grain yield. The meta QTL analysis revealed significant evidence for linkage of these traits to 39 different segments as candidates regions on maize genome. A total of 571 marker was selected as QTL or integrated QTL markers for narrowing down the QTL region into specific functionally relevant candidates.

Among these varieties, Samgang, Gumei4 and Apo showed the lowest of leaf water loss rate and strong drought tolerant phenotype. To identify drought QTLs with Samgang variety, we developed the doubled-haploid (DH) population consist of 101 lines derived from a cross the drought tolerant cultivar Samgang and the drought sensitive cultivar Nagdong. To score the drought phenotype degrees of this population, we withheld water for 6 weeks and treated the watering for 7 days. After watering, visual phenotype was observed 1 to 9 degree according to the standard evaluation system for rice, IRRI. Drought sensitive parent Nagdong was almost died and was scored as 9 degree, while tolerant parent Samgang showed slightly leaf tip drying phenotype and was scored as 3 degree in our experimental conditions. Three main QTLs were detected on chromosome 2, 6, and 11 with this visual phenotype. We also measured relative water contend of these population under drought stress conditions, and got one main QTL on chromosome 11. The QTL loci on chromosome 11 with flanking markers RM26755-RM287 has a function for visual phenotype and relative water content under drought conditions. *Corresponding Author: Tel. +82-55-350-1185, E-mail: jacob1223@korea.kr PC-74 DNA Profiling and Variety Identification using Insertion-Deletion (InDel) Polymorphisms in Cultivated Tomato Minkyung Kim, Sung-Chur Sim Sejong University, Dept. of Bioresources Engineering, Seoul, 143-747, Korea Cultivated tomato (Solanum lycopersicum L.) is an economically important vegetable and has a narrow genetic base due to intensive human selection through domestication and breeding. The low level of genetic variation between cultivated tomatoes has made it difficult to develop molecular markers for elite breeding lines. Recently, genome-wide 145,695 InDels were identified from in silico analysis of two tomato genome sequences, Heinz 1706 (S. lycoperiscum) and LA1589 (S. pimpnellifolium). Of these, 2,272 InDels were validated and 717 InDels showed polymorphism in cultivated tomatoes. In the present study, we selected 48 out of 717 InDels based on PIC value (> 0.3) and size (> 10 bp) to develop a DNA database for commercial tomato cultivars. We also used an additional set of 28 InDels that have been previously reported. These markers were distributed across 11 chromosomes with an average of 6.6 markers. A total of 48 F1 hybrid cultivars were collected from 20 seed companies and a subset of eight cultivars were used to test polymorphism of the InDel markers. The 37 InDel markers were polymorphic in these cultivars and were used to genotype additional 40 cultivars. Genetic distances and relationships between cultivars were assessed using the InDel genotypes of 48 cultivars. This analysis revealed that the InDel markers detected genetic variations to identify 46 cultivars. Our results demonstrate that the InDel markers will be a useful resource to construct a DNA database for tomato cultivars and to protect tomato breeder s rights via variety identification. - 179 -
PC-75 Proline accumulation and related gene expression in response to higher temperatures during deacclimation in peach shoot tissues Hyunsuk Shin 1,2, Sewon Oh 1,2, Keumsun Kim 1,2, Youngjae Oh 1,2, Jungyeon Won 1,2, Hyeondae Han 1,2, Daeil Kim 1,2* 1 Department of Horticulture, Chungbuk National University, Cheongju 361-763, Korea, 2 Brain Korea 21 Center for Bio-Resource Chungbuk National University, Cheongju 361-763, Korea Proline (Pro) accumulation is a common physiological reaction in response to abiotic stresses in many plants. Accumulation of Pro is believed to play the important role in protecting cellular components from dehydrating effects due to such stresses. The study was performed to investigate the relationship between cold hardiness and Pro content or expression of related genes in peach cultivars during a constant experimental deacclimation. Changes in cold hardiness were determined using electrolyte leakage method in the shoots of 10 peach cultivars (Prunus persica Aikawanakajima, Chiyomaru, Daewol, Janghowon Hwangdo, Kiraranokiwami, Mihong, Misshong, Soomee, Suhong, and Sun Gold ). Pro content was analyzed using the ninhydrin method and related gene expressions were examined using quantitative real-time RT-PCR. While cold hardiness of 10 peach cultivars decreased, Pro contents of those increased during the deacclimation. Notably, at the same time, expression of P5CS (Δ 1 -pyrroline-5-carboxylatesynthase) decreased in 10 peach cultivars, whereas expressions of P5CR (Δ 1 -pyrroline-5-carboxylatereductase) and OAT (ornithine-δ-aminotransferase) increased. Our results demonstrate that Pro responds positively to higher temperature in the shoots of 10 peach cultivars and expression of both P5CS and P5CR genes could show contrasting patterns during the deacclimation. Furthermore, our results suggest that ornithine pathway, which has been suggested to be important during seedling development, could serve as an alternative pathway in Pro synthesis process during the deacclimation in peach. *Corresponding Author: Tel. 043-261-2527, E-mail: dkpomo@cbnu.ac.kr - 180 -

The M. incognita resistance gene Me7 derived from Capsicum annuum CM334, is located on chromosome 9. In the present study, an F 2 population derived from a cross between ECW03R and CM334 was used to locate the Me7 gene. An F 2 population was inoculated using approximately 1,000 second-stage juveniles per individual plant. Phenotype screening was done 45 days after inoculation by using gall index system. The phenotype study of 503 F 2 individual showed 391 resistant and 112 susceptible plants. The 3:1 phenotypic ratio confirmed that resistance phenotype is controlled by a single dominant gene. Previously reported two markers were tested to reveal the linkage of markers to phenotype. Two markers, CAPS_F4R4 and SCAR_PM6a were located at 4.3 and 2.7 cm from the resistance gene, respectively. Additional SNP markers were developed using CM334 reference genome information to narrow down the position of the gene, but no closer markers could be developed due to errors of DNA sequence assembly. The closest marker was positioned on telomere of the chromosome 9 long arm, where tens of other NB-LRR genes are clustered. NB-LRR genes are being used as candidates to identify the Me7 gene. *Corresponding Author: Tel. 82-2-880-4563, E-mail: bk54@snu.ac.kr - 181 -

The pink-colored tomatoes with high soluble solids content are considerably preferred especially in Asia compared to the other colors. Generally the pink fruit trait of tomatoes is easily determined by visual examination of intact fruit, however, it is technically determined by the characteristic of the fruit peel. The pink trait is regulated by variations of the SlMYB12(y) gene located on chromosome 1, which controls the accumulation of the naringenin chalcone, which comprises a large proportion of flavonoids. In this study, we developed a derived Cleaved Amplified Polymorphic Sequences (dcaps) marker and a sequence characterized amplified regions (SCAR) marker in order to discriminate of pink/non-pinktomatoes in the domestic breeding lines. Quantitative RT-PCR analysis indicated that the SlMYB gene is highly expressed in non-pink fruit peel, whereas the expression is significantly lowered in the pink fruit peel. These gene based markers are expected to enhance the efficiency and accuracy of selection pink-tomatoes in tomato breeding programs. - 182 -
PC-79 Biosafety assessment and molecular biological characteristics for β-carotene biofortified transgenic rice Sung-Dug Oh, Soo-Yun Park, Doh-Won Yun, Soo-In Sohn, Hyun Suk Cho, Si Myung Lee * National Academy of Agricultural Science, Jeonju, 560-500 The β-carotene biofortified transgenic rice was developed by transforming rice cv. Nakdongbyeo with phytoene synthase (Psy) and carotene desaturase (Crt I) genes isolated from Capsicum and Pantoea. The aim of this study was to perform molecular characterization of rice transformants of T5-T7 generation harboring Psy and Ctr I genes driven by endosperm specific globulin promoter for biosafety evaluation of β-carotene biofortified transgenic rice. The structure and sequence of T-DNA in the transformation vector and the insertion sites, flanking sequences and generational stability of inserted T-DNA in transgenic rice lines were analyzed. The transformation vector consisted of right border, MAR gene, carotenogenic genes unit, herbicide resistance selectable marker unit, MAR gene and left border in sequential order. T-DNA was introduced at the position of 30,363,938-30,363,973 bp of chromosome No. 2 by adaptor-ligation PCR. Stable integration of T-DNA and stable expression of bar gene was confirmed in T5 to T7 generations. It was also confirmed that the backbone DNA of transformation vector containing antibacterial gene was not present in the genome of β-carotene biofortified transgenic rice. HPLC analysis confirmed that carotenoids were consistently detected through T5-T7 generations. *Corresponding Author: Tel. 063-238-4711, E-mail: tataby@korea.kr PC-80 Assessment of gene flow from disease resistant (OsCK1) genetically modified rice to its non-gm rice and weedy rice Sung-Dug Oh, Si Myung Lee, Soo-In Sohn, Hyun Suk Cho, Doh-Won Yun * National Academy of Agricultural Science, Jeonju, 560-500 Genetically modified (GM) crops have never been cultivated commercially in Korea, it is necessary for a thorough assessment of the risks associated with their environmental release. We determined the frequency of pollen mediated gene flow from disease resistant GM rice (OsCK1) to non-gm rice (Nagdongbyeo) and weedy rice (R55). A total of 449,711 or 164,604 seeds were collected from non-gm and weedy rice, respectively which were planted around OsCK1. Resistance of the hybrids was determined by repeated spraying of herbicide and DNA analysis using specific primer to confirm hybrids. Though non-gm rice and weedy rice have similar flowering time, the hybrids were found only in non-gm rice and out-crossing ranged from 0.018% at 0.3 m to 0.013% at 0.6 m. All of hybrids were located within 0.6 m distance from the GM rice plot in southerly direction. The meteorological factors including temperature and relative humidity during flowering time were found to be the most important factors for determining rice out-crossing. It should be considered many factors like the local weather condition and flowering time to set up the safety management policy to prevent pollen mediated gene flow between GM and conventional crop. *Corresponding Author: Tel. 063-238-4713, E-mail: dwyun@korea.kr - 183 -

In our previous study, changes in cold hardiness and proline content showed contrasting patterns during a constant deacclimation. This study was performed to investigate the proline accumulation and related gene expression in response to repeated deacclimation and reacclimation in peach cultivar Daewol. Proline content was analyzed using the ninhydrin method and related gene expressions were examined using quantitative real-time RT-PCR. Proline contents of Daewol increased during the repeated deacclimation treatments. Interestingly, during the twice deacclimation, expressions of P5CS (Δ 1 -pyrroline-5-carboxylatesynthase) constantly decreased, whereas expressions of P5CR (Δ 1 -pyrroline-5-carboxylatereductase) increased. Expressions of OAT (ornithine-δ -aminotransferase) indicated up- and down- pattern in response to repeated deacclimation and reacclimation. Our results indicated that proline responds positively to higher temperature in the shoots of peach cultivar Daewol and expressions of both P5CS and P5CR genes could show contrasting patterns during the deacclimation. Moreover, our results suggest that ornithine pathway could serve as an alternative pathway in proline synthesis process during deacclimation in peach. *Corresponding Author: Tel. 043-261-2527, E-mail: dkpomo@cbnu.ac.kr PC-82 Identification of single-nucleotide polymorphisms in Sw-5b resistance gene and development of a SNP marker to Tomato spotted wilt virus in tomato Hyung Jin Lee, Bo-Young Kim, Chang-Sik Oh * Department of Horticultural Biotechnology and Institute of Life Science & Resources, College of Life Sciences, Kyung Hee University, Yongin 446-701, Korea Tomato spotted wilt virus (TSWV) causes one of the most destructive viral diseases that threaten tomato (Solanum lycopersicum) worldwide. So far, eight TSWV resistance genes, Sw1a, Sw1b, sw2, sw3, sw4, Sw-5b, Sw-6, and Sw-7 have been identified and Sw-5b has been incorporated into tomato for prevention of TSWV. The objectives of this research are first to discover single nucleotide polymorphisms (SNPs) in Sw-5 alleles and then to develop SNP markers to distinguish resistant genotypes against TSWV for marker-assisted breeding in tomato. First, DNA sequences of Sw-5b alleles from both resistant and susceptible cultivars amplified using known Sw-5 gene-based marker was analyzed. The single functional SNP (G A) was detected as non-synonymous substitution because this SNP causes change of arginine (Arg 599 ) to glutamine (Gln 599 ). Next, the primer pair for high resolution melting analysis (HRM) was designed around this SNP. To determine accuracy of this SNP marker to distinguish resistant Sw-5b genotypes against TSWV, genotypes of 32 commercial tomato cultivars were checked. The newly developed SNP marker could select six cultivars carrying resistant Sw-5b genotype, which was 100% correlated with genotypes based on the gene-based marker. These results indicate that the SNP maker developed in this study could be useful for better tracking resistance to TSWV in tomato breeding. *Corresponding Author: Tel. 031-201-2678, E-mail: co35@khu.ac.kr - 184 -
PC-83 Development of the single-nucleotide polymorphism marker in Cf-9 gene conferring resistance to a leaf mold pathogen Cladosporium fulvum in tomato Bo-Young Kim, Hyung Jin Lee, Chang-Sik Oh * Department of Horticultural Biotechnology, College of Life Sciences, Kyung Hee University, Yongin 446-701, Korea. Leaf mold disease in tomato (Solanum lycopersicum) is caused by Cladosporium fulvum, a fungal leaf pathogen. One of effective ways to control leaf mold is to breed disease-resistant tomato cultivars. Cf-4 and Cf-9 resistance (R) genes encode proteins that carry a leucine rich repeat domain and are located in plasma membrane. They trigger hypersensitive response following recognition of corresponding Avr4 and Avr9 proteins of C. fulvum, respectively. Cf-4 and Cf-9 genes are originated from wild tomato species S. habrochaites and S. pimpinellifolium and have been introgressed into commercial tomato cultivars. These two highly homologous orthologs exist as a cluster with four highly homologous paralogs. Due to this reason, development of genetic markers to distinguish these two functional R genes from their orthologs and paralogs is difficult. In this study, we tried to develop single-nucleotide polymorphism (SNP) markers to select tomato cultivars carrying resistant Cf-9 genotype. The genomic sequences of resistant Cf-4 and Cf-9 alleles, susceptible cf-9 alleles, and their paralogs were obtained from the GenBank database, and two functional SNPs causing non-synonymous substitution were found among them. Based on two SNPs, the Cf-9_2-SNP-F/R primer set for high resolution melting (HRM) analysis was developed. HRM analysis with this primer set could successfully distinguish tomato cultivars carrying resistant Cf-9 allele among 30 commercial tomato cultivars, which were characterized with the gene-based marker. These indicate that the SNP marker developed in this study is useful to trace Cf-9 genotype efficiently in marker-assisted selection in tomato. *Corresponding Author: Tel. 031-201-2156, E-mail: co35@khu.ac,kr PC-84 Molecular characterization of transgenic plants using Next Generation Sequencing and Junction Sequence Analysis Ji Hye Ohn 1*, Andre Silvanovich 2, Carl Garnaat 2, Colton Kessenich 2, Qing Tian 2 1 Monsanto Korea, Ltd, Seoul, Korea 2 Monsanto Company, St. Louis, Missouri, U.S.A. Molecular characterization of crops improved through biotechnology has traditionally been conducted using Southern blot analysis which has been used to determine T-DNA copy number, the presence or absence of backbone (sequence outside of the T-DNA) and to demonstrate generational stability of the T-DNA insert. The advancement of high-throughput DNA sequencing (HTS) technology allows efficient characterization of the transgene incorportated into the genome of the plant by rapidly sequencing the entire plant genome. By combining NGS (Next Generation Sequencing) technologies with bioinformatic methods that identify the T-DNA insert derived from the plasmid vector and genome-t-dna junction sequences, it has been shown that conclusions equivalent to those of a Southern blot are readily obtained. NGS is done at sufficient coverage depth (>75x) across the entire genome. By mapping the sequence reads to the plasmid vector, and identifying the number of unique junctions, we can confirm insert number, copy number, absence of backbone, across multiple generations. With the widespread availability of NGS and steadily decreasing costs it is likely that academia and industry will fully transition to NGS-based molecular characterizations in the near future. *Corresponding Author: Tel. 02-3393-3765, E-mail: ji.hye.ohn@monsanto.com - 185 -
PC-85 QTL analysis for Agronomic Traits of Rice Recombinant Inbred Lines under Different Environments Mi-Ok Woo, Xing Huang, Eunbyeol Koh, Hee-Jong Koh * Department of Plant Science, Research Institute of Agriculture and Life Sciences, and Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-921, Republic of Korea Understanding how crops interact with their environments is increasingly important in breeding program, especially in light of highly anticipated climate changes. A total of 150 recombinant inbred lines (RILs) of F 12 generation derived from Dasanbyeo (Indica) x TR22183 (Japonica) were evaluated at Suwon 2010, Shanghai 2010, IRRI 2010 wet season, Suwon 2011, Shanghai 2011, IRRI 2011 dry season, and IRRI 2011 wet season as a total of seven diverse environments. Traits evaluation included eight important agronomical traits such as days to heading (DTH), culm length (CL), panicle length (PL), panicle number per plant (PN), spikelet number per panicle (SN), spikelet fertility (SF), 100-grain weight (GW), and grain yield (GY). As a result of genotyping using 384-plex GoldenGate oligo pool assay (OPA) set (RiceOPA3.1), the linkage map for 235 SNP markers covering a total of 926.53 cm with an average interval of 4.01 cm was constructed and a total of 44 main-effect quantitative trait loci (QTL)s and 35 QTLs by environment interaction (QEI) were detected for all eight traits using single environment and multi-environments analysis, respectively. Of these, fourteen putative QTLs for DTH, CL, PN, SN, GW and GY found in single environment analysis had the similar position to QEI for those traits, suggesting that these same QTLs from both single-and multi-environments are major and stable for certain traits. To the best of our knowledge, 12 QTLs consisted of four QTLs for CL (qcl2, qcl8.1, qcl8.2, and qcl8.3), six QTLs for GW (qgw3.1, qgw3.2, qgw7, qgw8, qgw10.1, and qgw10.2), one QTL for GY (qgy3) and one for SF (qsf4) out of 44 QTLs obtained from single environment analysis were considered to be novel since no overlapping QTL was reported from previous studies. In addition, 12 out of 35 QTLs obtained from multi-environments analysis were also novel.

But, at a high concentration in soil, copper acts as a major toxic element to plant cells due to its potential inhibitory effects against many physiological and biochemical processes. In this study, the morphological and physiological changes were observed in the leaf of sorghum plants treated with different concentrations (0, 100, and 150 µm) of Copper (Cu). The results linked to morphological changes that plants treated with Cu suffered reduction in growth and morphological changes. In the ion concentration investigation, the concentrations of Cu 2+ increased, the concentration of others interacting ions (Zn 2+, Ca 2+, Mn 2+, Fe 2+ ) were changed dramatically. For proteome analysis, 2-D combined with MALDI-TOF-TOF mass spectrometry was performed. Two dimensional gels stained with silver staining, a total of 422 differential expressed proteins ( 2-fold) were identified using Progenesis SameSpot software. A total of 24 spots from Cu-induced sorghum leaf and 21 spots from Cu-induced sorghum root were analyzed by mass spectrometry. Out of 24 protein spots from Cu-stressed leaf, of which 16 protein spots were up-regulated and 8 protein spots were down-regulated whereas out of 21 protein spots, a total of 9 protein spots were up-regulated and 12 spots were down-regulated from Cu-stressed root. Taken together, these studies revealed the effects of heavy metal, Cu on the growth and physiological characteristics in sorghum seedlings and proteome investigation, hoping to provide references on the mechanism of heavy metal damaging plants.

However, the molecular responses induced by Cd have so far been grossly overlooked. This study examines the morpho-physiological alterations combined with proteome changes in leaves of Sorghum bicolor when exposed to Cd. Ten days old sorghum seedlings were exposed to different concentrations (0, 100, and 150 µm) of CdCl 2 and a significant accumulation of Cd in the leaves was recorded by ICP analysis. Furthermore, the effects of Cd exposure on protein expression patterns in S. Bicolor was investigated by two-dimensional gel electrophoresis (2-DE) and the 2-DE profile of leaf proteins from both control and Cd-treated seedlings were compared quantitatively using Progenesis SameSpot software. Results lined to morphological changes that plants treated with Cd suffered reduction of growth. The concentration of Cd was markedly reversed by the Cd treatments, whereas the absorption degree of Cd was increased by the higher concentration of Cd by confocal microscopy. Using 2-DE method, a total of 33 differentially expressed protein spots were identified by MALDI-TOF-TOF mass spectrometry. Of those, 13 protein spots were significantly enhanced/reduced while 20 reduced under Cd treatment. The most of the up-regulated proteins are involved in oxidative response, glutathione and sulfur metabolism as well as the secondary metabolite biosynthesis. Collectively, our study provides insights into the integrated molecular mechanisms of early responses to Cd and growth and physiological characteristics of sorghum seedlings hoping to provide references on the mechanism of heavy metal damaging plants.

This study was conducted in order to profile proteins from the hormone induced diploid and tetraploid roots using high throughput proteome approach. Two dimensional gels stained with CBB, a total of 64 differential expressed proteins were identified from the diploid root using image analysis by Progenesis SameSpot software. Out of total differential expressed spots, 20 differential expressed protein spots ( 2-fold) were analyzed using MALDI-TOF-TOF mass spectrometry whereas a total of 13 protein spots were up regulated and 7 protein spots were down-regulated. However, in the case of tetraploid root, a total of 78 differential expressed proteins were identified from tetraploid root of which a total of 28 differential expressed protein spots ( 2-fold) were analyzed by mass spectrometry whereas a total of 16 protein spots were up regulated and a total of 12 protein spots were down-regulated. However, proteins identified using iproclass databases revealed that the identified proteins from the explants were mainly associated with the nucleic acid binding, oxidoreductase activity, transporter activity and isomers activity. The exclusive protein profile may provide insight clues for better understanding the characteristics of proteins and metabolic activity in various explants of the economically important medicinal plant Platycodon grandiflorum.

Ltd., BI Center, GIST, Gwangju 500-712, Korea 4 Dept. of Industrial Plant Science & Technology, Chungbuk National University, Cheong-ju 361-763, Korea The roots of Platycodon grandiflorum are massively used in traditional herbal medicine as a remedy for pulmonary disease and respiratory disorders. However, in spite of its potential medicinal significance, the molecular mechanism of its roots is still unknown. In the present study, high throughput proteome approach was conducted to profile proteins from 3, 4 and 5 months aged diploid and tetraploid roots of Platycodon grandiflorum. Two dimensional gels stained with CBB, a total of 68 differential expressed proteins were identified from diploid root out of 767 protein spots using image analysis by Progenesis SameSpot software. Out of total differential expressed spots, 29 differential expressed protein spots ( 2-fold) were analyzed using LTQ-FTICR MS whereas a total of 24 protein spots were up regulated and 5 protein spots were down-regulated. On the contrary, in the case of tetraploid root, a total of 86 differential expressed proteins were identified from tetraploid root out of 1033 protein spots of which a total of 39 differential expressed protein spots ( 2-fold) were analyzed using LTQ-FTICR MS whereas a total of 21 protein spots were up regulated and a total of 18 protein spots were down-regulated. It was revealed that the identified proteins from the explants were mainly associated with the nucleotide binding, oxidoreductase activity, transferase activity. In that way, the exclusive protein profile may provide insight clues for better understanding the characteristics of proteins and metabolic activity in various explants of the economically important medicinal plant Platycodon grandiflorum.

In these crops, the resveratrol-enriched transgenic rice plant has moved ahead to generate the dossier for regulatory review process required for commercialization of GM crop. The resveratrol-enriched transgenic rice plant could be released to farmers for cultivation after national regulators have determined that it is safe for the environment and human health. Here we developed a PCR-based DNA marker based on flanking sequences of transgene for the discrimination of zygosity in resveratrol-enriched transgenic rice plant. This DNA marker will be useful for identifying of resveratrol-enriched transgenic rice plant, and can also be use to estimate transgene movement occurred by pollen transfer or seed distribution. *Corresponding Author: Tel. 063-238-4706, E-mail: woo001@korea.kr PC-91 Selection of β-carotene enhanced transgenic soybean containing single-copy transgene and analysis of integration sites Yang Qin 1, Soon-Jong Kweon 2, Young-Soo Chung 3, Sun-Hwa Ha 4, Kong-Sik Shin 1, Myung-Ho Lim 1, Taek-Ryoun Kwon 1, Soon Ki Park 5, Hyun-Suk Cho 1, Hee-Jong Woo 1* 1 National Academy of Agricultural Science, Rural Development Administration, Jeonju, 560-500, Korea 2 National Institute of Crop Science, Rural Development Administration, Suwon, 441-707, Korea 3 Department of Genetic Engineering, Dong-A University, Busan, 604-714, Korea 4 Department of Genetic Engineering, KyungHee University, Yongin, 446-701, Korea 5 School of Applied Biosciences, Kyungpook National University, Daegu, 702-701, Korea The β-carotene biofortified transgenic soybean was developed recently through Agrobacterium -mediated transformation using the recombinant PAC (Phytoene synthase-2a-carotene desaturase) gene in Korean soybean (Glycine max L. cv. Kwangan). GM crops prior to use as food or release into the environment required risk assessments to environment and human health in Korea. Generally, transgenic plants containing a copy of T-DNA were used for stable expression of desirable trait gene in risk assessments. Also, information about integration site of T-DNA can be used to test the hypothesis that the inserted DNA does not trigger production of unintended transgenic proteins, or disrupt plant genes, which may cause the transgenic crop to be harmful. As these reasons, we selected four transgenic soybean lines expressing carotenoid biosynthesis genes with a copy of T-DNA by using Southern blot analysis, and analyzed the integration sites of their T-DNA by using flanking sequence analysis. The results showed that, T-DNA of three transgenic soybean lines (7-1-1-1, 9-1-2, 10-10-1) was inserted within intergenic region of the soybean chromosome, while T-DNA of a transgenic soybean line (10-19-1) located exon region of chromosome 13. This data of integration site and flanking sequences is useful for the biosafety assessment and for the identification of the β-carotene biofortified transgenic soybean. *Corresponding Author: Tel. 063-238-4706, E-mail: woo001@korea.kr - 191 -

The nutritional composition of two lines of transgenic rice plants (RTB5 and RTB11) was compared with that of its non-transgenic counterpart. The results showed that, except for small differences in dietary fiber and some minerals, there was no significant difference between transgenic rice and conventional counterpart variety with respect to their nutrient composition. Most of measured levels of nutrients were within the range of values reported for other commercial cultivars, showing substantial equivalency. Therefore, the insertion of transgenes did not affect the nutritional composition of transgenic RTB5 and RTB11 rice grains. *Corresponding Author: Tel. 063-238-4706, E-mail: woo001@korea.kr PC-93 Characterization of chrysanthemum genome by NGS So Youn Won 1*, Seulki Lee 1, Jae-A Jung 2, Jung Sun Kim 1, Sangho Kang 1, Seong-Han Sohn 1 1 National Academy of Agricultural Science, RDA, Jeonju, 560-500, South Korea 2 National Institute of Horticultural and Herbal Science, RDA, Wanju, 565-852, South Korea The Asteraceae/Compositae family is one of the biggest families in flowering plants and has more than 23000 species including the economically important lettuce, sunflower, and chicory as well as the agronomic weeds. With its significance and the progress in sequencing technology, its species have been subjected to the genome sequencing project worldwide. Although chrysanthemum is an important plant in the floricultural industry, however, it has been less studied at the level of genomics, compared with other species in the Asteraceae. There were only several reports on comparative analysis of transcriptome for chrysanthemum. Actually, the genome of Chrysanthemum species is known to be gigantic and complex with diverse status ranging from diploid to decaploid. Since the cultivated and commercial chrysanthemum exhibits hexaploid genome, we decided to select the diploid species with smaller genome as a material for reference genome sequencing. Thus, we launched a genome sequencing project with C. boreale which was previously reported to be diploid by cytogenetic analysis. We constructed sequencing libraries with insert size 300bp and 500bp and sequenced them from the paired end in 100bp read length with Illumina s HiSeq platform. After quality checking, we preprocessed raw reads by removing duplicated reads and trimming reads with low quality value. Kmer frequency analysis with the cleaned reads showed that the genome is heterozygous, highly repetitive and gigantic, ranging from 2.9Gb to 5.8Gb. The cleaned reads were further subjected to error correction and primary assembly with SOAPdenovo2. Here, we ll report the result of Kmer frequency analysis and genome assembly. *Corresponding Author: Tel. +82-63-238-4561, E-mail: soyounwon@korea.kr - 192 -

PC-95 Rice FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 (OsFKF1) promotes flowering independent of photoperiod. Su-Hyun Han 1*, Soo-Cheul Yoo 2*, Nam-Chon Paek 1 1 Department of Plant Science, Plant Genomics and Breeding Institute, Research Institute of Agriculture and Life Sciences, Seoul National University, Seoul 151-921, Korea 2 Department of Plant Life and Environmental Science, Hankyong National University, Ansung 456-749, Korea, In the facultative long-day (LD) plant Arabidopsis thaliana, FLAVIN-BINDING, KELCH REPEAT, F-BOX1 (FKF1) is activated by blue light and promotes flowering through the transcriptional and post-transcriptional regulation of CONSTANS under inductive LD conditions. By contrast, the facultative short day (SD) plant rice (Oryza sativa) flowers early under inductive SD and late under non-inductive LD conditions; the regulatory function of OsFKF1 remains elusive. Here we show that osfkf1 mutants flower late under SD, LD, and natural LD conditions. Transcriptional analysis revealed that OsFKF1 up-regulates expression of the floral activator Ehd2 and down-regulates expression of the floral repressor Ghd7; these regulators up- and down-regulate Ehd1 expression, respectively. Moreover, OsFKF1 can upregulate Ehd1 expression under blue light treatment, without affecting the expression of Ehd2 and Ghd7. In contrast to the LD-specific floral activator Arabidopsis FKF1, OsFKF1 likely acts as an autonomous floral activator because it promotes flowering independent of photoperiod, probably via its distinct roles in controlling expression of rice-specific genes including Ehd2, Ghd7, and Ehd1. Like Arabidopsis FKF1, which interacts with GI and CDF1, OsFKF1 also interacts with OsGI and OsCDF1 (also termed OsDOF12). Thus, we have identified similar and distinct roles of FKF1 in Arabidopsis and rice. *Equal contributors to this work.

The saponins derived from P. grandiflorum were termed platycosides and platycodin D, which is the most abundant saponin in the plant and pharmacologically active component, was intensively studied. Platycodin D is synthesized from triterpenoids by several enzymes including cytochrome P450. Cytochrome P450 is known to exist in superfamily in plant kingdom and essential roles in saponin biosynthetic pathway by hydroxylation or oxidation of triterpene skeletons. However, the key genes of P450 involved in biosynthesis of saponin was not identified because of its low conservation rate in amino acid sequence level among plant species and gene superfamilies. Recently, next generation sequencing (NGS) technology is rapidly developed as a method to discover target genes. In this study, we tried to identify P450 genes involved in saponin biosynthetic pathway from the various tissues of P. grandiflorum using RNA-seq analysis. The sequencing was performed using Illumina Hi-Seq platform after cdna library preparation. The produced reads were assembled using CLC Genomics Workbench software (CLC Bio, Inc.).

We isolated two full-length cdna gene, CuCRTISO and CuCRTISO-like, from Citrus unshiu. To confirm whether these two genes have the function of the carotenoid isomerase, The full-length cdna of CuCRTISO and CuCRTISO-like gene, respectively, were fused with 35S promoter and NOS terminal region and then transformed into tomato CRTISO mutant, Tangerine, which shows orange fruit due to lack of carotenoid isomerase activity. The mature fruit color of the transgenic line expressing CuCRTISO gene changed from orange to red, which was similar to the fruit color of the tomato Money Maker. We also carried out HPLC analysis to detect all-trans lycopene, which is produced from prolycopene by carotenoid isomerase. In the transgenic line expressing CuCRTISO the all trans lycopene was detected from mature fruit but in the tangerine mutant several prolycopenes were detected from it. On the other hand, the transgenic line expression of CuCRTISO gene retained the orange-color fruit at the mature stage as Tangerine mutant. These studies indicate that the CuCRTISO gene has a function of carotenoid isomerase and also plays a role of it in other plant species, and that the CuCRTISO-like gene might be not enough to produce the all trans lycopene or has a another unknown function(s). *Corresponding Author: Tel. 064-754-3357, E-mail: mong6908@gmail.com - 196 -
PC-101 Phylogenomic analysis and a systematic view of MLO family in rice Van Ngoc Tuyet Nguyen, Ki-Hong Jung Department of Plant Molecular Systems Biotechnology & Graduate School of Biotechnology, Kyung Hee University, Yongin 446-701, Republic of Korea MLO is a unique gene family which is identified in plant and carries out abiotic and biotic stress responses in various plants. The understanding on the roles and functional diversity of this family is quite limited in rice, a model crop plant. Rice genome has 12 potential MLO family members. To do systematic functional assignment of MLO family in rice, we performed phylogenomic analysis of integrating meta-expression data based on public sources of microarray data or RT-PCR data into the phylogenic tree. As a result, we identified 12 MLO genes carrying various tissue-preferred expression patterns such as leaf, root, pollen, and ubiquitous expression, suggesting functional diversity in terms of anatomy or development. RT-PCR analysis confirmed, integrated transcriptome data were used to estimate the functional redundancy or specificity among MLO family: MLO12 showed mature pollen preferred expression; MLO4, root tip; MLO10, overall root except root tip; MLO8, leaf; MLO2 and MLO9 showed redundant expression in overall tissues except root. Also, abiotic stress meta-expression data and RT-PCR performance suggested the functional association of 5 MLO and 6 MLO genes with heat and cold stress, respectively. Our analysis will provide basic information to study diverse developmental or physiological phenomena mediated by MLO family in rice, a major model crop plant. PC-102 Functional characterization of soybean FT homologs in photoperiod-dependent flowering time control Kyung-Hee Lee, Cheol Woo Choi, Wook-Hun Jung, Min-Chul Kim * Division of Applied Life Science (BK21 Plus), Plant Molecular Biology and Biotechnology Research Center, Gyeongsang National University, Jinju 660-701, Korea. FT is one of the major floral activator in photoperiod-dependent flowering pathway. To understand the role of FT homologs in flowering time control of short-day plant soybean, we identified ten soybean FT genes and named GmFTs. Phylogenetic analysis revealed that ten GmFT genes were further categorized into three subclades. Gene expression analysis showed that the most GmFT genes are mainly expressed in leaves. The expression of GmFT2a, GmFT2b, GmFT5a, and GmFT6 was strongly induced under the floral inductive short-day condition, but GmFT4 exhibited opposite expression pattern compared to those of GmFT2a, GmFT2b, GmFT5a, and GmFT6. To understand roles of GmFT genes in flowering, we generated Arabidopsis transgenic plant overexpressing GmFT genes. Both 35S:GmFT2a and 35S:GmFT5a transgenic plants showed extremely early flowering. In contrast, overexpression of GmFT4 delayed flowering of transgenic plants compared to wild type Arabidopsis. The results indicated that GmFT2a and GmFT5a might function as floral activators, while GmFT4 has an opposite function in soybean flowering. Moreover, domain swapping approaches between GmFT2a and GmFT4 revealed that the substitution of the segment B region alone, which is located in 4 th exon, was sufficient to change the function of GmFT2a to floral repressor and GmFT4 to floral activator. The results suggested that soybean FT homologs have been functionally diversified during evolution and might play different roles in photoperiod-dependent flowering of soybean. *Corresponding Author: Tel. 055-772-5428, E-mail: mckim@gnu.ac.kr - 197 -
PC-103 Transgenic Forage Plants Overexpressing a alfalfa Hsp23 Gene Exhibit Enhanced Tolerance to Abiotic Stresses Ki-Won Lee, Ki-Yong Kim, Hee Chung Ji, Tae Young Hwang, Sang-Hoon Lee * Grassland and Forages Division, National Institute of Animal Science, Rural Development Administration, Cheonan, 330-801, Korea To develop transgenic forage crops with enhanced tolerance to abiotic stress, we introduced an alfalfa Hsp23 gene expression vector construct through Agrobacterium-mediated transformation. Integration and expression of the transgene were confirmed by PCR, northern blot, and western blot analyses. Under normal growth conditions, there was no significant difference in the growth of the transgenic plants and the non-transgenic controls. However, when exposed to various stresses such as salt or arsenic, transgenic plants showed a significantly lower accumulation of hydrogen peroxide and thiobarbituric acid reactive substances than control plants. The reduced accumulation of thiobarbituric acid reactive substances indicates that the transgenic plants possessed a more efficient reactive oxygen species-scavenging system. We speculate that the high levels of MsHsp23 proteins in the transgenic plants protect leaves from oxidative damage through chaperon and antioxidant activities.

PC-106 Characterization of Siberian wild rye grass EsHsp16.9 Gene and Their Expression under Various Environmental Conditions Sang-Hoon Lee, Ki-Yong Kim, Hee Chung Ji, Tae Young Hwang, Ki-Won Lee * Grassland and Forages Division, National Institute of Animal Science, Rural Development Administration, Cheonan, 330-801, Korea Small heat shock proteins (Hsps) are one of most conserved molecular chaperones that protect stress-inducible denaturation of substrates in living organisms. Small Hsps consist of a large subfamily categorized by subcellular localization ranging in size from 12 to 40 kda. Here, we identified and characterized a small Hsp 16.9 gene (EsHsp16.9) from Siberian wild rye (Elymus sibiricus L.). EsHsp16.9 is a 456-bp cdna with an open reading frame predicted to encode a 151-amino acid protein. It possesses a conserved ɑ-crystallin domain, which is a unique domain for small Hsps; shares high sequence similarity with cytosolic class I small Hsps among the small Hsp subfamily in Arabidopsis; and is close (96% similarity) to small Hsp in wheat. Northern blot analysis showed that EsHsp16.9 transcripts were enhanced by heat, drought, arsenate, methyl viologen, and H 2 O 2 treatments. Moreover, we expressed and purified recombinant EsHsp16.9 proteins in Escherichia coli to confirm its activity as a molecular chaperone. We found that recombinant EsHsp16.9 exhibits effective molecular chaperone activity, as determined by inhibition of thermal aggregation of malate dehydrogenase (MDH), which is broadly used as a model substrate.

To understand the molecular mechanism of leaf morphogenesis in rice, ethylmethane sulfonate (EMS) treated Ilpoom mutant line with semi-narrow and adaxially rolled leaf phenotype was identified. The leaf rolling character is said to be more advantageous under high temperature and heat stress, and play as one of the defensive mechanisms. The F1 plants, generated from a cross of Ilpoom and mutant, showed normal phenotype. Genetic analysis of its F2 population suggested that the mutation was controlled by a single recessive gene with segregation ratio of 3:1. Using F2 mapping population derived from a cross of Ilpoom mutant and Milyang23, each chromosomes were screened with STS markers by the bulked segregant analysis (BSA) method. The candidate region was detected to a long arm of chromosome 1 near the centromeric region. Fine mapping of the locus is currently conducted. Moreover, other morphological characterizations of the mutant plants were identified. Cytological analysis of the leaf suggested that deformation of the bulliform cells led to the smaller size and less number of the bulliform cells, and caused leaf rolling trait.

Thanks to many new genes brought from genomic research, It is possible to introduce various candidate genes through genetic transformation to see the performance of the genes in field. In our lab, soybean transformations have been tried for last 10 years to probe the possibility of traits improvement by transformation of new gene into soybean. For this purpose, three different genes were transformed into Korean soybean variety, Kwangan. First, the gene that controls early flowering of plant was transformed into Kwangan. Second, a candidate gene for soybean mosaic virus (SMV) resistance was transformed to produce transgenic plants. Third, another candidate gene for drought tolerance was transformed. All the transgenic plants from three genes transformation were produced for their gene insertion and their expression using PCR, qrt-pcr.

In this study, to investigate distinctive glutenin proteins and expression level for characteristic processing properties, we carried out qualitative and quantitative analysis of gluetenin protein in noodle and bread wheat cultivars by two-dimensional electrophoresis. Unexpectedly, five LMW-GS spots were found to be expressed at a common position in all cultivars and these spots may play something in glutenin biosynthesis. Also we found LMS-GS spots to distinguish Korean wheat cultivars mostly used as noodle and western bread wheat cultivars. These spots may contribute to characteristic processing properties. The 2DE results for each cultivar will be used as reference map or protein marker discriminating wheat cultivars, wheat and rice, imported and Korean flour. For quantitative analysis of gluetenin, we calculated relative expression level of the HMW-GS, LMW-GS and HMW-GS/ LMW-GS ratio in each cultivar by 2DE. The results presented in this study provide new insight into relation of specific glutenin proteins and end-use quality and will be useful to choose elite breeding line for improvement of wheat flour quality. *Corresponding Author: E-mail: jy0820@korea.kr - 202 -
PC-111 Comprehensive Identification of Low-Molecular-Weight Glutein Subunit Genes and Their Protein Products in a Korean Common Wheat Variety Keumkang Hye-Rang Beom *, Sun-Hyung Lim, Young-Mi Kim, Jong-Yeol Lee National Academy of Agricultural Science, RDA, Suwon, 441-707, Korea Although it is well known that low-molecular-weight glutenin subunits (LMW-GS) affects bread and noodle processing quality, the function of specific LMW-GS proteins mostly remain unclear. It is important to find a corresponding gene for a specific LMW-GS protein in order to understand the function of the specific LMW-GS protein. The objective of this study was to identify LMW-GS genes and haplotypes using well known Glu-A3, Glu-B3 and Glu-D3 gene specific primers and to interlink their protein products by proteomic approaches in a wheat variety. A total of 36 LMW-GS genes and pseudo-genes were amplified including 11 Glu-3 gene haplotypes, designated as GluA3-13K and GluA3-22K (pseudogene) at Glu-A3 loci, GluB3-33K and GluB3-43K at Glu-B3 loci and GluD3-11K, GluD3-21K, GluD3-31K, GluD3-42K, GluD3-5K, GluD3-6K and GluD3-393K (pseudogene) at Glu-D3 loci. To determine the relationship between gene haplotypes and their protein products (to identify the corresponding LMW-GS proteins), we conducted N-terminal amino acid sequencing and tandem mass spectrometry (MS/MS) analysis of the 17 LMW-GS spots separated by 2-DGE. Successfully, LMW-GS proteins of the Glu-3 gene haplotypes except pseudo-genes mentioned above were identified. This is the first report on comprehensive characterization of LMW-GS genes and their corresponding proteins and establishment of specific correspondence between each other in a single wheat cultivar. Our approach will be useful to understand the molecular basis of the LMW-GS and to study their contribution to the end-use quality of flour. *Corresponding Author: E-mail: gpfkd0629@jbnu.ac.kr - 203 -
PC-112 Activation of Anthocyanin Biosynthesis by Expression of the Radish R2R3 MYB Transcription Factor gene RsMYB1 Sun-Hyung Lim 1*, Sun-Hwa Ha 2, MinJi Choi 1, Da-Hye Kim 1, SangKyu Park 1, Jong-Yeol Lee 1, Young-Mi Kim 1 1 National Academy of Agricultural Science, Rural Development Administration, JeonJu, 560-500, Korea 2 Graduate School of Biotechnology, Kyung Hee University, Yongin, 446-701, Korea Anthocyanins, providing the bright red-orange to blue-violet colors, flavonoid-derived pigments with strong antioxidant activity that have benefits for human health. We isolated RsMYB1, which encodes an R2R3 MYB transcription factor (TF), from red radish plants (Raphanus sativus L.) that accumulate high levels of anthocyanins. RsMYB1 shows higher expression in red radish than in common white radish, in both leaves and roots, at different growth stages. regulatory genes. Transient expression of RsMYB1 in tobacco showed that RsMYB1 is a positive regulator of anthocyanin production. Also, the synergistic effect of RsMYB1 with B-Peru was larger than the effect of Arabidopsis plants stably expressing RsMYB1 produced red pigmentation throughout the plant, accompanied by up-regulation of the six structural and two regulatory genes for anthocyanin production. This broad transcriptional activation of anthocyanin biosynthetic machinery in Arabidopsis included up-regulation of TRANSPARENT TESTA 8, which encodes a bhlh-type TF. These results suggest that overexpression of RsMYB1 promotes anthocyanin production by triggering the expression of endogenous bhlh genes as potential binding partners for RsMYB1. In addition, RsMYB1-overexpressing Arabidopsis plants had a higher antioxidant capacity than did non-transgenic control plants. Taken together, RsMYB1 is an actively positive regulator for anthocyanins biosynthesis in radish plants and it might be one of the best targets for anthocyanin production by single gene manipulation being applicable in diverse plant species. *Corresponding Author: Tel. 063-238-4615, E-mail: limsh2@korea.kr - 204 -

Some variations induced in the process of plant transformation have often been observed in regenerated plants. In this study, we investigated the insertion number of transgene and the flanking sequences of T-DNA in tall-induced line BP23, which was unexpectedly gained in the process of transformation of insect-resistant rice with crybp1 gene, and also analyzed the whole-genome sequencing by using the NGS technologies to gain a better understanding of the sequence and structural changes between tall line or natural cultivar and rice reference. than others, was confirmed with two copies of foreign gene insertion, which was inserted in one genomic site facing each other between the position 2,430,152~2,430,151 of rice chromosome 12 without any deletion of genomic sequences. Sequencing analysis also revealed that 18bp-unknown sequences were added in the 5 insertion site of T-DNA. This position in rice genome was confirmed with none of expressed gene sites. By the NGS analysis, we detected 86560 SNPs and 1091/1472 large insertion/deletion (indel) sites (100bp) between BP23 and rice reference, and 84743 SNPs and 1094/1451 large indels between natural cultivar Nagdong and rice reference.

Of 196 gene-targeted PCR primer pairs, we successfully amplified 118 intron-containing genes (60.2%) and obtained a total of 1,870 introns with an average size of 143 nucleotides. Species-based compilation of 5 - and 3 -splicing motifs showed lineage-specific conservation in each splicing motif. Compilation of the entire intron set permitted prediction of the consensus sequences of splicing signal motifs in legumes, A Y G W GTA B A B G H and T V NC/TAGG H T V for the 5 - and 3 -splicing motifs, respectively. Interestingly, these consensus motifs are very similar to the corresponding splicing signals of two model systems, Arabidopsis and rice. This result is suggestive of conservation of pre-mrna splicing mechanisms in higher plants. Multiple alignments of CALTL introns demonstrated that the region from the branch point to 3 splice site was relatively more conserved than the region from5 splice site to the branch point. Phylogenetic analysis demonstrated that each of three splicing motifs, 5 -splice sites, 3 -splice sits, and branch site, was relevant to evolutionary divergence of species and phylogenetically informative, suggesting that splice signal sequences would be useful as a potential tool for the molecular phylogenetic analysis. *Corresponding Author: Tel. 051-200-7508, E-mail: hkchoi@dau.ac.kr - 205 -

There has been increasing demands for various types of chrysanthemums, such as cut flowers, potted plants and bedding plants. However, the genomic studies of this species have been not extensively conducted relative to other ornamental species due to high levels of polyploidy (2n = 4x =36 or 2n = 6x = 54) and heterozygosity as well as large genome size. In this work, we developed a molecular tool for cultivar identification using simple sequence repeats (SSRs) and investigated genetic diversity in 127 chrysanthemum cultivars. Of the 150 SSR primer pairs tested in this study, 62 primers were obtained from previous studies, while 88 primers were designed using the unigene sequences of C. nankingense and the Expressed Sequence Tag (EST) sequences of C. morifolium in the NCBI database. Thirty SSR primers were selected based on polymorphism and banding patterns in a subset of 8 cultivars and used to amplify the DNA of 127 chrysanthemum cultivars. The UPGMA dendrogram based on these 30 SSR markers showed that most of chrysanthemum cultivars were divided into five clusters. These results will benefit chrysanthemum research community to develop elite cultivars. *Corresponding Author: Tel. +82234084374, E-mail: jinheelim@sejong.ac.kr - 206 -

Citrus export to USA is also prohibited by the disease. Therefore, development of citrus canker resistant variety is essential and exploitation of markers for molecular breeding is urgent. To develop DNA molecular markers, we performed whole genome resequencing for 8 varieties: 4 citrus canker resistant varieties including C. hybrid Kioymi and 4 citrus canker susceptible varieties including C. iyo Miyauchiiyokan. In total, 642 polymorphic SNPs were detected between resistant and susceptible varieties. Of the 642 SNPs, 50 SNPs were preferably selected based on integrative genomics viewer. To apply the markers in a broad range of citrus variety, we performed genotyping with 6 other varieties very well known as citrus canker resistant and susceptible varieties in addition to previous mentioned 8 varieties. Three of the 50 SNPs were identified as a marker to distinguish citrus canker resistant varieties from susceptible varieties. Secondly, we developed molecular markers to apply for F1 lines crossed by Kiyomi and Miyauchiiyokan. Of the 50 SNPs, we identified 2 SNP markers to distinguish between F1 resistant and susceptible lines. One of them is a resistance gene that plays a role in plant defense mechanism. In this study, we developed 5 molecular marker candidates possible to apply for molecular breeding to develop citrus canker resistant variety. We are working on development of candidate markers related to citrus canker.

Target region amplification polymorphism (TRAP) is a rapid and efficient PCR-based marker technique, which uses bioinformatics tools and expressed sequence tag (EST) database information to generate polymorphic markers around targeted candidate gene sequences. TE-TRAP is a new marker system which used terminal inverted repeat (TIR) instead of targeted candidate gene sequences. Sorghum holds a good potential plant organism for transposon tagging due to its small genome size, low amount of repetitive DNA and co-linearity with other cereal genomes, which allows the use of information derived from sorghum in other cereal grasses. IS2868 of sorghum accession was treated Gamma irradiation on seed. To define availability and utilization of TE-TRAP, twenty-one accessions were used to evaluate the genetic diversity and underlying relationships. One-thousand thirty-three TE-TRAP markers were amplified by thirty-one primer combination. Altogether, 712 (62.8%) markers were observed polymorphic segregation, whereas 421 (37.2%) showed monomorphic patterns. To estimate genetic differentiation of population by various gamma radiation doses, the analysis of molecular variance (AMOVA) was performed using 4 to 5 different radiation doses population of M1 sorghum individuals. This study and marker system will provide valuable information to assist radiation mutation breeding. PC-118 Functional Characterization of PaLEAFY, a FLORICAULA/LEAFY orthologue in Phalaenopsis aphrodite Seonghoe Jang 1,2 1 Biotechnology Center in Southern Taiwan/Agricultural Biotechnology Research Center, Academia Sinica, Taiwan 2 Institute of Tropical Plant Science, National Cheng Kung University, Tainan, Taiwan The plant-specific transcription factor, LEAFY (LFY) is considered to be a master regulator of flower development in the model plant, Arabidopsis. This protein plays a dual role in plant growth, integrating signals from the floral inductive pathways and acting as a floral meristem identity gene by activating genes for floral organ development. Although LFY occupies an important position in flower development, the functional divergence of LFY homologues has been demonstrated in several plants including monocots and gymnosperms. In particular, the functional roles of LFY genes from orchid species such as Phalaenopsis that contain unique floral morphologies with distinct expression patterns of floral organ identity genes remain elusive. Here, PaLFY, a orthologue of Arabidopsis LFY from Phalaenopsis aphrodite subsp. formosana, a Taiwanese native monopodial orchid was isolated and characterized through analyses of expression and protein activity. PaLFY transcripts accumulated in the floral primordia of developing inflorescences and the PaLFY protein had transcriptional autoactivation activity forming as a homodimer. Furthermore, PaLFY rescues the aberrant floral phenotypes of Arabidopsis lfy mutants. Over-expression of PaLFY alone or together with PaFT1, a P. aphrodite subsp. formosana homologue of Arabidopsis FLOWERING LOCUS T (FT) in rice caused precocious heading. Consistently, higher chlorophyll content in the sepals and morphological changes in epidermal cells were observed in the floral organs of PaLFY knock-down orchids generated by virus-induced gene silencing. Taken together, these results suggest that PaLFY is functionally distinct from RICE FLORICAULA/LEAFY (RFL) but similar to Arabidopsis LFY based on phenotypes of our transgenic Arabidopsis and rice plants. - 208 -

In a previous study, a high-resolution physical map targeting a cluster of yield-related QTLs for grain weight, spikelets per panicle has been constructed using series of BC 3 F 4 nearly isogenic lines (NILs) derived from a cross between the Korean japonica cultivar Hwaseong and O. rufipogon. The QTLs including grain weight trait have been mapped in a 25.5kb region containing three genes. Based on GenBank database, these genes include male sterility 5 (OsMs5, LOC_Os09g36740), similar ascorbate peroxidase (OsApx, LOC_Os09g36750) and glutelin family protein (OsGlu, LOC_Os09g36760). Their endogenous expression patterns were analyzed in various rice tissues (2-week seedling, flag leaf, root and panicle) from the parental lines, Hwaseong and NIL-gw9. Semi-quantitative RT-PCR and qrt-pcr were performed using gene specific primer sets. The cdnas of the similar OsApx gene of Hwaweong and NIL-gw9 were cloned. Over-expression and RNAi knock-down transgenic plants using three genes are under construction for the functional characterization of the genes. The results will be discussed. *Corresponding Author: Tel. 042-821-7038, E-mail: ahnsn@cnu.ac.kr PC-120 Delaying the tomato fruit ripening by sound wave treatment Mi-Jeong Jeong 1*, Joo-Yeol Kim 1, Jin Su Lee 2, Soo In Lee 1, Jin-A Kim 1 1 Department of Agricultural Biotechnology, National Academy of Agricultural Science (NAAS), 370 Nongsaengmyoeng-ro, Wansan-gu, Jeonju, Jeollabuk-do,560-500, Korea 2 Postharvest Research Team, National Institute of Horticultural and Herbal Science (NIHHS), 100, Nongsaengmyeong-ro, Iseo-myeon, Wanju-gun, Jeollabuk-do, 565-852, Korea Regulation of fruit ripening may help extend fruit shelf life and prevent losses due to spoilage. Here, we investigated whether sound treatment could delay tomato fruit ripening. We treated harvested tomato fruits with low-frequency sound waves (1 khz) for 6 h, and then monitored various characteristics of the fruits over 14-day period at 23±1 C. Seven days after the treatment, 85% of the treated fruits were green, versus fewer than 50% of the non-treated fruits. Most of the tomato fruits had switched to the red ripening stage by 14 days after treatment. Ethylene production and respiration rate were lower in the treated than non-treated tomatoes. Furthermore, changes in surface color and flesh firmness were delayed in the treated fruits. To investigate how sound wave treatment affects fruit ripening, we analyzed the expression of ethylene-related genes by quantitative real-time RT-PCR analysis. We found that the expression level of several ethylene biosynthetic and ethylene signaling pathway-related genes was influenced by sound wave treatment. These results demonstrate that sound wave treatment delays tomato fruit ripening by altering the expression of important genes in the ethylene biosynthesis and ethylene signaling pathways. *Corresponding Author: Tel. 063-238-4617, E-mail: center1097@korea.kr - 209 -
PC-121 Enhanced post-germinative growth of encapsulated somatic embryos of Siberian ginseng (Eleutherococcus senticosus) by carbohydrate addition to the encapsulation matrix. Su-Jin Jung 1*, Ui-Soo Yoon 2, Yong-Eui Choi 3 1 Div. of Biotechnology, Korea Forest Research Institute, Suwon, Republic of Korea 2 Dept. of Biology, Kongju Nat l Univ., Kongju, Republic of Korea 3 Dept. of Forestry, Kangwon Nat l Univ., Chuncheon, Republic of Korea This experiment was carried out to enhance plantlet conversion and ex vitro survival of encapsulated somatic embryos of Siberian ginseng. Cotyledonary somatic embryos were encapsulated with 3.0% sodium alginate and 96% of conversion rate in terms of plantlet with well-developed epicotyl marked when the encapsulated embryos were placed on perlite soils wetted with sucrose solution as for carbon source. However, post-germinative growth of encapsulated embryos was suppressed in case of sucrose did not added. Instead of sucrose alone, the addition of both sucrose and starch to the sodium alginate enhanced the post-germinative growth of the embryos. In sodium alginate matrix with 2% sucrose, the survival rate of the encapsulated embryos was more than twice (23.5%) that of ones without sucrose (10.0%). Embryos encapsulated with both 2% sucrose and 1% starch showed the highest percentage (42.1%) of survival rate was shown. In analysis of Iodine staining and starch content in the sodium alginate matrix, the starch component was decomposed when the embryos started to germinte. This result indicated that the carbohydrate treatments (starch and sucrose) in the encapsulation matrix enhanced the survival rate of post-germinative growth of encapsulated embryos in Siberian ginseng. *Corresponding Author: Tel. 010-4412-2038, E-mail: windy7942@hanmail.net PC-122 Characterization of roles of soybean GIGANTEA genes in day-length dependent flowering Wook-Hun Jung, Cheol Woo Choi, Kyung Hee Lee, Hyun Min Cho, Min Chul Kim * Division of Applied Life Science (BK21 Plus program), The Research Institute of Natural Science, Gyeongsang National University, Jinju 660-701, Korea Major loci controlling flowering time and maturity of short-day plant soybean, E1, E2, E3, E4, E5, E6, E7 and E8, have been identified in soybean. The gene corresponding to E2 locus is a homolog of Arabidopsis GIGANTEA (AtGI). We identified three GI homologs in soybean and are verifying their roles in day-length dependent flowering. Expression anlysis indicated that GmGIs are ubiquitously expressed at all developmental stages of soybean plants. Diurnal expression of GmGIs fluctuates within light/dark cycles of long-day (LD) and short-day (SD). GmGI2 and GmGI3 have identical expression patterns under both day length conditions with the highest peak at zeitgeber time 8 h (ZT8) under LD and at ZT4 under SD. GmGI1 shows the peak at ZT12 under LD and at ZT8 under SD. All of GmGIs exhibit the earlier peak and the shorter phase under SD than LD. The results indicated that day length affects expressions of GmGIs. Subcellular localization analysis showed that GmGIs are mainly targeted to nucleus, similar to the localization of AtGI. Overexpression of GmGIs in Arabidopsis transgenic plants showed no significant effect on flowering time nor rescue of gi-2 mutant phenotype. The results suggested that GmGIs have different molecular functions in flowering time regulation of short-day plant soybean compared to long-day plant Arabidopsis. To investigate the molecular mechanisms of GmGIs functions in soybean flowering time control, we intend to identify target gene of GmGIs and interacting proteins by using yeast two-hybrid assay. *Corresponding Author: Tel. 055-772-1874, E-mail: mckim@gnu.ac.kr - 210 -
PC-123 Characterization of OsJAC1 which is responding to different types of ionizing radiation In jung Jung *, Jung Eun Hwang, Sung Min Han, Hong-Il Choi, Soon-Jae Kwon, Jin-Baek Kim, Si-Yong Kang, Dong Sub Kim Advanced Radiation Technology Institute, Korea Atomic Energy Research Institute, Jeongeup 580-185, Republic Korea Ionizing radiation affects gene expression from plant genomes. To monitor the genome-wide transcriptional changes induced by three types of ionizing radiation, we used the rice RNA sequencing to identify genes that are up- or down-regulated by gamma rays (GAs), proton (PRs) and ion beams (IBs). The Oryza sativa jacalin-like lectin domain containing proteins (OsJAC1) gene was highly induced by GAs, PRs and IBs. OsJAC1 was selected based on the expression patterns of a genome-wide dataset of RNA sequencing. Many jacalin-related lectin genes have been shown to be associated with disease resistance, biotic and abiotic stress signaling. Therefore, we studied its expression pattern in response to different abiotic stress and phytohormone treatments. The expression patterns of OsJAC1 under two different abiotic stress conditions (salt and heat stress) and phytohormones (salicylic acid and methyl jasmonate) were examined. The transcripts of OsJAC1 were significantly induced in response to abiotic stress conditions, including salt and heat treatments. In addition, it was induced in response to the salicylic acid and methyl jasmonate treatments, respectively. To investigate the sub-cellular localization of OsJAC1, the gene was expressed as a fusion protein tagged with GFP, in tobacco leaf epidermis and examined under confocal microscope. The OsJAC1 was clearly localized at the nucleus. These results provide critical insights into the molecular functions of the rice jacalin-like lectin domain containing proteins as receptors of external signals. *Corresponding Author: Tel. 063-570-3311, E-mail: bioplant@kaeri.re.kr PC-124 De novo transcriptome assembly of Perilla citriodora and expression profile study Junkyoung Choe 1, Woo Kyung Lee 1, Ji-Eun Kim 1, Myoung Hee Lee 2, Tae-ho Kim 3, Sung- Hwan Jo 1, Jeong-Hee Lee 1* 1 SEEDERS Inc., 11-3, 1 Techno-ro, Yuseong-gu, Daejeon 305-509, Korea 2 National Institute of Crop Science, RDA, Miryang 627-803, Korea 3 Genomics Division, National Academy of Agricultural Science, RDA, Jeonju 560-500, Korea The high quality of gene set is necessary to study the functional research of genes. Although perilla is cultivated as an oil crop and as a vegetable crop in Asian countries such as Korea, Japan, northeast China and Nepal, the reference genome is absent. To assembly perilla gene set, we sequenced the various tissues of perilla (Perilla citriodora) RNA-seq with Illumina HiSeq platform, generating 548,549,314 short reads. When de novo transcriptome assembly was performed with five samples, 86,396 and 38,413 transcripts were assembled as total and representative transcripts, respectively. Using 1,917,424 proteins at Phytozome ver. 9.1, we annotated the perilla assembled transcripts, and 66,139(76.55%) and 24,030(62.55%) transcripts showed the similarity with known plant proteins (E-value < 1e-10) as total and representative transcripts, respectively. Among the diverse molecular functions, we were interested in the regulatory components, such as transcription factor and transcription regulator. Using this data, we identified 499 transcripts annotated the putative transcription factor differentially expressed transcripts. 165 putative transcription factors were significantly expressed in perilla flower and 121 putative transcription factors in both leaf and flower. This study provides the perilla reference gene set and the understanding of the molecular regulation of transcription factor dependent on the tissue. *Corresponding Author: Tel. 042-710-4035, E-mail: jhlee@seeders.co.kr - 211 -
PC-125 Investigation of morphological characteristics and pollen germination in Senna tora Jin-Tae Jeong 1*, Seon-Woo Cha 1, Bo-Keun Ha 2 1 Department of Herbal Crop Research, National Institute of Horticultural and Herbal Science, RDA, Eumseong 369-871, Republic of Korea 2 Chonnam National University, Gwangju 500-757, Republic of Korea Senna tora (L.) Roxb. belongs to Leguminosae and its seeds are usually roasted and boiled in water to produce tea in Korea. Also the plants are well known for the treatment of Hypertension, Hepatitis, Constipation and Conjunctivitis. This study was conducted to investigate the morphological characteristics and pollen germination rates of Senna tora with the aim of genetic mapping of this species. First, we investigated morphological characteristics of domestic and international genotypes containing 51 lines in Korea and 2 lines in China. No significant differences in growth characteristics were observed among 53 genotypes. However, ST-9 line which was collected in Pyung-chang showed high growth rate at the early stage. The flower of Senna tora consists of 5 petals, 10 surgeries (7 main surgeries, 3 small surgeries), 1 pistil, and 5 sepals. After bud emergence, each petal was white in 1-2 days, turn into ivory in a week, then yellow in 8-9 days and finally bloomed in 9-10 days. Although the average flowering times of the plants were July 24, ST9 flowered in July 12. In addition, the flowers of ST9 differed from the flowers of the other genotypes. Flower of ST9 joined together with one another. Therefore, ST9 showing high growth rate at the early stage and unique flowering characteristics was selected to as the paternal line for genetic mapping study. Second, we investigated pollen germination rates for each stage of flower development. Pollen started to germinate at the yellow bud stage and pollen germination rate was highest in the bloomed flower stage. This results show that self-fertilization hardly occurs when the flower is ivory bud stage, and there is no need to use young bud flowers for artificial crossing. This work is intended to serve as the basis for the breeding of new varieties in Senna tora. * 주저자 : Tel. 043-871-5576, E-mail: powjjt@korea.kr - 212 -
PC-126 Molecular Breeding of Pepper Varieties (Capsicum annuum) Containing High Levels of Capsinoids Hyeon-Seok Jeong, Hee-Bum Yang, Siyoung Jang, Yeong Deuk Jo, Byoung-Cheorl Kang * Department of Plant Science, Seoul National University, Seoul 151-921, The Republic of Korea Capsinoids, low-pungent compounds, have the same biological effects as capsaicinoids such as anticancer and anti-obesity. A precursor of capsinoids, vanillyl alcohol, is known to be produced by mutations in the putative-aminotransferase (pamt) gene. In the previous study, SNU11-001 (Capsicum chinense) containing high levels of capsinoids was identified in germplasm collections of Capsicum. This collection has a unique mutation in the pamt gene that can cause dysfunction of this gene. In order to develop pepper varieties containing high capsinoids contents, marker-assisted foreground and background selections were performed during backcross breeding. Compared to the conventional backcrossing, marker-assisted backcrossing (MABC) is extremely useful for recovery of a recurrent parent s genetic background. For foreground selection, plants carrying the pamt/pamt genotype were selected from a BC 1 F 1 and BC 2 F 1 populations using SCAR markers derived from the unique pamt mutation of SNU11-001. To obtain background selection markers, a total of 412 single nucleotide polymorphism (SNP) markers was screened on Shinghong parental lines and SNU11-001 to obtain polymorphic SNP markers. Of the 412 SNP markers, 144 and 204 polymorphic SNP markers evenly distributed in pepper genome were finally selected. BC 1 F 1 and BC 2 F 1 plants carrying the pamt/pamt genotype were subjected to background selection using the selected marker sets. Multiple genotype analysis was done using a high-throughput genotyping system (EP1 TM, Fluidigm, USA). As a result, one BC 1 F 1 plant 84% similar to the recurrent parent and several BC 2 F 1 plants more than 96% recovery rate of the recurrent parent were selected. Genetic backgrounds of the selected BC 2 F 1 plants were evaluated by the genotype-by-sequencing (GBS) method in order to confirm the background selection results using the SNP marker set. GBS results showed that recovery rate and positions of introgressed segments were well matched between two methods demonstrating MABC can be successfully done with a couple hundred SNP markers. *Corresponding Author: Tel. 02-880-4563, E-mail: bk54@snu.ac.kr - 213 -

In contrast to most epiphytic powdery mildew species, L. taurica is an endophytic fungus which colonizes in the mesophyll tissues of the leaf. In the genus Capsicum, several studies have been conducted to identify resistance sources to L. taurica. In previous studies, five quantitative trait loci (QTLs) for powdery mildew resistance have been identified. An F 2 population derived from self-pollination of the commercial cultivar Capsicum annuum PM Singang was used for genetic analysis of powdery mildew resistance. Resistance of the F 2 plants was tested under the natural environmental conditions. Sporulation intensity on infected leaves was used as a disease scale to assign resistance levels to plants, where 0-5% is Resistant, 6-15% Moderate resistant and 16-100% Susceptible. A total of 83 F 2 plants were evaluated for resistance. The results showed that 59 plants were resistant, 10 susceptible and 14 moderately resistant. If we consider MR as S, segregation ratio fitted to a single dominant resistance gene model. In the future study, closely linked molecular marker will be developed and tested to locate this gene. The developed marker will be used to identify the powdery mildew resistance gene.

PC-130 Development of novel strategy for antifungal crop using trans-kingdom small RNA movement Byung-Jun Jin, Hyun Jin Chun, Min Chul Kim * Division of Applied Life Science (BK21 Plus Program), The Research Institute of Natural Science, Gyeongsang National University, Jinju 660-701, Republic of Korea. Small RNAs, such as micrornas (mirnas) and small interfering RNAs (sirnas), play crucial roles in post-transcriptional gene silencing (PTGS) in eukaryotes. Small RNAs function cell-autonomously as well as non-cell-autonomously. It has been well characterized that pathogenic fungi secrete some effector molecules facilitating their infection into plants. However, it is unclear whether molecules produced in plant cells are able to move into fungal cells during infection. To test if small RNAs generated from plant cells can move to fungal cells during infection, we generated transgenic Arabidopsis and rice plants expressing sirnas targeting GFP gene generated from double-stranded RNA interference (dsrnai) constructs for GFP gene. And then these transgenic plants were inoculated with transgenic rice blast fungus, Magnaporthe oryzae, expressing GFP transgene. Here, we showed that ectopic expression of sirnas targeting GFP gene in transgenic plants significantly suppressed GFP expression in rice blast fungi inoculated, indicating that small RNA molecules generated in plant cells can move into infected fungal cells and efficiently degrade fungal GFP transcripts. Our results would provide a new small RNA-based strategy for the development of resistant crops against fungal pathogens. *Corresponding Author: Tel. 055-772-5428, E-mail: mckim@gnu.ac.kr PC-131 Caffeic acid O-metyltransferase (COMT) is involved in the melatonin synthesis in rice (Oriza sativa) plants Geun-hee Choi, Yeong Byeon, Hyoung Yool Lee, Kyoungwhan Back * Department of Biotechnology, Bioenergy Research Center, Chonnam National University, Gwangju, Republic of Korea Caffeic acid O-methyltransferase (COMT) methylates N-acetylserotonin into melatonin; that is, it has N-acetylserotonin O-methyltransferase (ASMT) activity. The ASMT activity of COMT was first detected in Arabidopsis thaliana COMT (AtCOMT). To confirm the ASMT activity of COMT in other plant species, we evaluated the ASMT activity of a COMT from rice (Oryza sativa) (OsCOMT). Purified recombinant OsCOMT protein from Escherichia coli was used to validate the high ASMT activity of OsCOMT, similar to that of AtCOMT. The K m and V max values for the ASMT activity of OsCOMT were 243 µm and 2,400 pmol/min/mg protein, which were similar to those of AtCOMT. Similar to AtCOMT, OsCOMT was localized in the cytoplasm. In vitro ASMT activity was significantly inhibited by either caffeic acid or quercetin in a dose-dependent manner. Analogously, in vivo production of melatonin was significantly inhibited by quercetin in 4-week-old detached rice leaves, suggestive of a positive role of COMT in melatonin biosynthesis in plants. *Corresponding Author: Tel. 062-530-0441, E-mail: kback@chonnam.ac.kr - 216 -

Here, we investigated changes in the seasonal concentrations of metabolites of current-year stem tissues in 6-year-old Pinus densiflora at June, August, and October. 76, 75, and 78 metabolites were assigned at June, August, and October by GC/MS. Among these compounds, 55 metabolites were commonly found in all three times, and they were divided into six groups according to the variation of concentrations in each times. Among 56 metabolites, the concentrations of three inositol-methylated derivatives, myo-inositol, ononitol, and pinitol in current-year stem tissues at August were significantly correlated with the heights of nursery-grown trees. Furthermore, we found that such metabolites were significantly correlated with stem diameter at 27 years for two consecutive years. Therefore we suggest that seasonal differences in the contents of inositol derivatives may explain much of the natural variation seen for tree stem size in even-aged pine forests. And these have the potential as metabolic markers of inherently rapidly growing trees in the early selection of those conifer families. *Corresponding Author: Tel. 031-290-1164, E-mail: mnchoi1022@korea.kr PC-134 Systemic analyses of expression patterns and structural variation of soybean flowering genes in natural accessions Cheol-Woo Choi, Wook-Hun Jung, Kyung-Hee Lee, Min-Chul Kim * Division of Applied Life Science (BK21 Plus), Plant Molecular Biology and Biotechnology Research Center, Gyeongsang National University, Jinju 660-701, Korea. Soybean is a short-day plant, which means short day length promotes flowering. So far nine major loci, E1 to E8 and J, affecting the timing of flowering and maturity have been genetically identified in soybean. To understand the roles of soybean flowering genes in photoperiod-dependent flowering time control in soybean, we analyzed not only expression patterns of E1, E2, E3 and E4 genes as well as soybean FT homologs, including GmFT2a, GmFT5a and GmFT4, but also structural variation of E1, E2, E3, and E4 genes in various soybean accessions exhibiting a broad range of flowering time. The mrna level of GmFT2a and GmFT5a was low in late flowering accessions, but high in late flowering accessions. In contrast, GmFT4 exhibited opposite expression pattern to those of GmFT2a and GmFT5a. Structural variation of E1, E2, E3 and E4 gene in these accessions revealed that early and moderate flowering accessions contained non-functional alleles of E1, E2, E3 and E4 genes in their genome. These results suggested that expression patterns of GmFT2a GmFT5a and GmFT4 would be important factor determining flowering time in soybean and allelic variation and genetic combination of upstream E1, E2, E3, and E4 genes would be more important in soybean flowering time control than their gene expression patterns. *Corresponding Author: Tel. 055-772-5428, E-mail: mckim@gnu.ac.kr - 218 -
PC-135 Characterization of the aquaporin family genes and stress responsive expression profiling in Brassica rapa Md. Abdul Kayum, Jong-In Park, Nasar Uddin Ahmed, Gopal Saha, Ill-Sup Nou * Department of Horticulture, Sunchon National University, Sunchon 540-742, Korea Efficient infiltration of water through cell membranes is arbitrated by a family of transmembrane water channels called aquaporins (AQPs). Aquaporin belongs to a highly conserved group of membrane proteins called major intrinsic proteins that facilitate the transport of water and a variety of low molecular weight solutes across biological membranes,which is essential for plants to survive in stress conditions. This study identified 59 BrAQP genes from B. rapa database and Br135K microarray dataset, which was formed by applying low-temperature stresses to contrasting Chinese cabbage two inbreed lines, Chiifu and Kenshin. Based on phylogenetic analyses of BrAQPs revealed four distinct subfamilies, such as plasma membrane intrinsic proteins (PIP), tonoplast intrinsic proteins (TIP), NOD26-like intrinsic proteins (NIP), small basic intrinsic proteins (SIP) with aquaporin of Tomato and Arabidopsis thaliana. All BrAQP genes were firstly examined through homology study with existing biotic and abiotic stress resistance-related aquaporin genes of other plant species and found a high degree of homology. We selected PIP subfamily genes for expression analysis based on microarray data with high and differential transcript abundance levels and homology study with stress related aquaporin genes of other plant species. In our study, we characterized all B. rapa aquaporin genes and understanding the BrPIP subfamily gene function in plants under various environmental stimuli, the expressions of BrPIP genes under various abiotic stress conditions including cold, drought, salinity, water logging, ABA treatment and Fusarium oxysporum f. sp. Conglutinans infection were investigated by a quantitative real-time reverse transcription-pcr analysis. In our expression analysis, 4 BrPIP genes showed responsive expression against F. oxysporum f. sp. Conglutinans infection. The selected genes showed an organ-specific expression, and 12 out of 22 BrPIP genes were differentially expressed in Chiifu compared to Kenshin under cold stresses. Only 7 genes showed up regulation under drought stress and incase of salt stress 17 BrPIP genes were more responsiveness. Additionally, 18 BrPIP genes were up regulated by ABA treatment and all BrPIP genes showed down regulation under water logging stress. Together with expression and bioinformatic analyses, our results provides novel basis to allocate the stress-related biological function to each PIP gene. *Corresponding Author: Tel. +82-61-750-3249, E-mail: nis@sunchon.ac.kr - 219 -
PC-136 Carotenoids Synthesis Gene Analysis in pepper Ayoung Jung 1, Hyeon-Seok Jeong 1, Dong Kyu Lim 2, Yeaseong Ha 1, Arti Rai 1, Jin-Kyung Kwon 1, Sung Won Kwon 2, Byoung-Cheorl Kang 1* 1 Department of Plant Science, Plant Genomics and Breeding Institute, and Vegetable Breeding Research Center, College of Agriculture and Life Sciences, Seoul National University, Seoul, 151-921, Republic of Korea 2 College of Pharmacy, Seoul National University, Seoul, 151-921, Republic of Korea Carotenoids are vital pigments responsible for yellow, orange and red color in plants. In Capsicum, capsanthin-capsorubin synthase (CCS), phytoene synthase (PSY), β-carotene hydroxylase (CRTZ-2) and lycopene β-cyclase (LCYB) were identified to be involved in the carotenoids synthesis pathway. Previously molecular markers based on the CCS and PSY genes have been developed to distinguish fruit colors in pepper. However these markers can distinguish fruit colors of limited pepper genotypes. Therefore, there is need of developing additional markers for accurate prediction of fruit colors using molecular markers. In this study carotenoids contents of 16 pepper accessions were analyzed and the CCS, PSY, CRTZ-2, LCYB genes were sequenced to identify the genes affecting the fruit color. Among all the analyzed carotenoids, capsanthin was accumulated in much higher amount in red and orange fruits (1100-2500 mau min and 30-500 mau min respectively) while violaxanthin (20-1200 mau min) was accumulated more in yellow fruits. Sequence analysis revealed that deletions and two frame shift mutations in CCS gene for yellow accessions. Frame shift mutations of the PSY gene were detected in two orange accessions. These results show that mutations in CCS and PSY genes affect the fruit colors of pepper, and markers can be developed using mutations of these genes.

To identify host factors involved in CMV-P1 infection, a yeast two-hybrid system derived from C. annuum Bukang cdna library was used. A total of 156 potential clones interacting with the CMV-P1 RNA helicase domain were isolated. These clones were confirmed by β -galactosidase filter lift assay, PCR screening and sequence analysis. Then, we narrowed the ten candidate host genes which are related to virus infection, replication or virus movement. To elucidate functions of these candidate genes, each gene was silenced by virus induced gene silencing in Nicotiana benthamiana. The silenced plants were then inoculated with green fluorescent protein (GFP) tagged CMV-P1. Virus accumulations in silenced plants were assessed by monitoring GFP fluorescence and enzyme-linked immunosorbent assay (ELISA). Among ten genes, silencing of formate dehydrogenase (FDH) or calreticulin-3 (CRT3) resulted in weak GFP signals of CMV-P1 in the inoculated or upper leaves. These results suggested that FDH and CRT3 are essential for CMV infection in plants. The importance of FDH and CRT3 in CMV-P1 accumulation was also validated by the accumulation level of CMV coat protein confirmed by ELISA. Altogether, these results demonstrate that FDH and CRT3 are required for CMV-P1 infection in plants. - 220 -
PC-138 Genotyping-by-sequencing (GBS) for assessment of genetic diversity in pepper germplasm Koeun Han, Heayoung Lee, Jin-Kyung Kwon, Byoung-Cheorl Kang * Department of Plant Science, Plant Genomics and Breeding Institute, and Vegetable Breeding Research Center, College of Agriculture and Life Sciences, Seoul National University, Seoul 151-921, Republic of Korea Pepper (Capsicum spp.) germplasm shows diverse phenotypic variations including fruit size, color, pungency, and many other horticultural traits. Traditional markers including SSR, AFLP, and RFLP have been used to construct genetic maps using biparental populations. However to assess the genetic diversity of large number of germplasm, a robust and rapid marker development and genotyping approach is needed. We used six pepper accessions including C. annuum, C. chinense, C. baccatum and C. frutescens and performed genotyping-by-sequencing (GBS). To select the most appropriate condition, eight different 2 bp selective nucleotides were used to make GBS libraries. Selective nucleotide OO showed the largest number of reads in all samples, and 11,026 to 47,957 high-quality SNPs were called in six accessions. When C. annuum CM334 genome sequence was used as a reference, C. annuum showed the smallest number of SNPs, while C. baccatum which was known to be a different Capsicum clade showed the largest number of SNPs. Pepper core collection chosen to represent the genetic diversity of whole germplasm will be genotyped by high-density SNPs developed from GBS. We will perform genome-wide association study (GWAS) using genetic and phenotypic variation to identify the functional genetic loci controlling horticultural traits. *Corresponding Author: Tel. 82-2-880-4563, E-mail: bk54@snu.ac.kr PC-139 Effects of ionizing irradiation on mutation induction and nuclear DNA content in Oryza Sativa L.

To access the physiological response of rice to different types of ionizing radiation, rice seeds were exposed to gamma-ray and ion beam radiation. Exposure to ionizing radiation dramatically decreased the shoot length compared with non-irradiated plants. Fluorescence-activated-cell-sorting (FACs) was used to measure DNA contents. There were significant correlations of dose-dependent between irradiated plant and non-irradiated plant. The radicals induced by the ionizing radiation in the plant could be observed by electron spin resonance (ESR). It was confirmed that the number of free radicals in cell was greatly increased all irradiated plants than non-irradiated plant. A significant positive correlation was shown between ionizing radiation dose and signal intensity. In order to determine the Genetic diversity, AFLP analysis was conducted with the irradiated plant and non-irradiated plant. Based on band patterns, the cluster analysis was conducted to evaluate the genetic variation by using the UPGMA (Unweighted Pair Grouping Method of Averages). Genetic diversity of irradiated plants by low dose ion beam was the closest non-irradiated plant and irradiated by high dose gamma-ray was the furthest from non-irradiated. We describe the detailed methods of ionizing irradiation and discuss its applications in genetic research as well as plant breeding. *Corresponding Author: Tel. 063-570-3310, E-mail: bioplant@kaeri.re.kr - 221 -

The number of alleles of 12 microsatellites detected ranged from eight at CH03d12 to 18 at CH01f07. Gene diversity ranged from 0.7053 at CH01d08 to 0.9224 at CH01f07. The lowest value of PIC was 0.6600 at CH01d08 and the highest was 0.9171 at CH01f07. A group consisting of Ooharabeni, Bartlett, and P. calleryana was out-grouped and served as a reference to determine the relationship among Asian pear accessions. Except for the out-group, 50 Asian pears were segregated into two groups. Group I was divided in two small groups. Each small group was characterized by P. bretschneideri and P. ussuriensis, respectively. Group II was characterized as P. pyrifolia, and the group was divided in four small groups. The eigenvalue, difference, proportion, and cumulative of six principal components based on PCA to 12 microsatellite. The eigenvalue of the first principal components was 5.5850. The proportion of the first principal component was 0.9308. The cumulative value of the first two principal components was 0.9801. Consequently, nearly all of the results were elucidated by the two principal components. The results from analysis of the standard set of microsatellites in this study may be used as basic materials for the management of Asian pear germplasm collections, and the data might be useful in the development of a core collection. *Corresponding Author: Tel. 043-261-2527, E-mail: dkpomo@cbnu.ac.kr - 222 -

Sch. Agr. Life Sci., Univ. Tokyo 2 Center for Sustainable Resource Science, RIKEN 3 Fruit Research Division, National Institute of Horticultural and Herbal Science, RDA, Wanju 565-850, Korea As one of the most severe stress conditions, drought strongly affects the plant growth and productivity. OsPIL1, a gene encoding a rice Phytochrome Interacting Factor (PIF)-Like transcription factor, was found to be down-regulated under drought stress condition. OsPIL1 shows a diurnal expression pattern and known to be involved in regulation of plant height. However, the mechanisms of down-regulation of OsPIL1 expression under stress conditions are remained unclear. In this study, the expression of PIF4 and PIF5, the most homologous genes of OsPIL1 in Arabidopsis, was analyzed and the expression of these genes were found to be oscillated in circadian manner and down-regulated in response to drought and low temperature similar to that of OsPIL1. To identify the regions involved in the responses to drought, low temperature and diurnal cycle, the promoter analysis of PIF4 was performed using transgenic Arabidopsis. Further promoter analysis is ongoing to specify regulatory regions in more detail. *Corresponding Author: Tel. 063-238-6743, E-mail: gsmoon@chol.com PC-142 Development of molecular markers for evaluation of low temperature germinability in rice germplasm Do Yoon Hyun 1*, Sukyeung Lee 1, Yu-Mi Choi 1, Myung-Chul Lee 1, Se Jong Oh 1, Thomas H.

Although rice (Oryza sativa L.) is generally sensitive to low temperatures, genetic variation for LTG exists and several quantitative trait loci (QTLs) have been reported. The objective of this study was to develop and employ high-efficiency molecular markers for evaluation of LTG in rice germplasm. A panel of japonica rice accessions (n=180) from temperate regions in Asia was evaluated for LTG and genotyped with markers from regions previously reported to harbor other LTG QTLs. ANOVA revealed that four markers on chromosome 2, 4, and 11 from previously reported QTLs showed highly significant value (p < 1.0e-04) and their R 2 ranged 0.083 (qltg11-1) to 0.190 (qltg4b-1). An association analysis was conducted using SNP data generated by sequencing of the panel. Eight SNP markers were found to be significantly associated with LTG using general and mixed linear models. Three SNP-based CAPS and dcaps markers from these results were developed and showed higher accuracy in predicting sensitive LTG germplasm. These new LTG markers will be useful for molecular evaluation of germplasm, particularly to identify sensitive or weak LTG accessions. *Corresponding Author: Tel. 063-238-4912, E-mail: dyhyun@korea.kr - 223 -

One of the plant pigments, anthocyanins are a group of flavonoid compounds well known as pigments responsible for blue, purple, red, or yellow coloration of plant tissues. In this study, we investigated the pigmentation of purple and yellow color seed according to wheat grain developmental stages. The contents of anthocyanin and chlorophyll in the purple and yellow seeds were measured. Chlorophyll contents were changed similarly in both purple and yellow color seed, and no significant difference was observed between them. In purple color seed, the content of anthocyanin was significantly induced compared with yellow color seed. The individual anthocyanin components were investigated by ultra performance liquid chromatography (UPLC). Cyanidine-3-glucoside (C3G) and peonidine-3-glucoside (P3G) were detected as predominant anthocyanin in purple color wheat. To investigate whether structural genes in anthocyanin biosynthesis were involved in the trait differences between purple and yellow color seed, we examined the expression of anthocyanin biosynthesis-related genes (CHS, CHI, F3H, DFR, ANS, UFGT) and MYB transcription factor in developing wheat grains by using qrt-pcr. This study indicates that the expression of anthocyanin biosynthesis-related genes and MYB transcription factors correlate with anthocyanin levels of grain. *Corresponding Author: Tel. 063-570-3313, E-mail: jbkim74@kaeri.re.kr PC-144 DNA 바코드분석을통한국내자생난지형잔디의분류 양대화 2+, 홍민지 1+, 정옥철 2+, 진일두 2, 박미영 2, 김양지 1, 이효연 1,2* 1 제주대학교생명공학부 2 제주대학교아열대원예산업연구소 + 공동 1 저자 잔디는공원과정원, 학교운동장, 묘지, 골프장, 스포츠경기장, 도로변과같이다양한장소에식재되고있는주요작물이다. 이러한잔디는생육적온에따라크게난지형잔디와한지형잔디로구분된다. 그중한국잔디 (Zoysiagrass) 는대표적인난지형잔디로, 들잔디 (Zoysia japonica) 와금잔디 (Zoysia matrella), 갯잔디 (Zoysia sinica), 왕잔디 (Zoysia macrostachya) 등이있지만, 국내자생잔디의품종구분이명확하지않아체계적인보존과관리가어려운실정이다. 최근특정염기서열구간을이용해종을식별하는 DNA 바코드분석법이개발되어, 다양한생물종을빠르고정확하게구별하는것이가능해졌다. 따라서, 본연구에서는자생잔디의분류를위한 DNA 바코드시스템구축하고이것을바탕으로체계적인잔디관리를수행하고자국내의자생한국잔디 ( 들잔디, 금잔디, 갯잔디 ) 약 500 점이상수집하고, 지역별로들잔디와금잔디, 갯잔디의 DNA 바코드분석을수행중에있다. 사사 : 본연구는산림청국립품종관리센터산림유전자원개발사업와 2009 년도정부 ( 교육부 ) 의재원으로한국연구재단의지원을받아수행된기초연구사업임 (No.2009-0094059) * 주저자 : Tel. 064-754-3347, E-mail: hyoyeon@jejunu.ac.kr - 224 -

To explore the matter, the present study applied fluorescent in situ hybridization (FISH) to the mitotic metaphase chromosome of Chrysanthemum boreale with C 0 t DNA as probes. Based on DNA re-assotiation kinetics, three kinds of C 0 t DNA exhibiting different degrees of repetitive nature were fractionated and used as FISH probes to map the repetitive sequences. Signals from all C 0 t DNAs were successfully observed but their coverage on the chromosomes was different among C 0 t-1, C 0 t-10, and C 0 t-100. C 0 t-1 FISH signals resulted to have its intensity on the telomeric region and were also dispersed on both chromosome arms except for some distal regions. In C 0 t-10, signals were observed in all parts of the chromosome with greater intensity around pericentromeric regions. FISH with C 0 t-100 DNA was observed in bright signals all over the chromosome. Signals of C 0 t FISH found in this study covered the regions where ribosomal DNAs and telomeric repeats of C. boreale have been distributed (previous report), thus signifying their repetitive attributes. The present results could enhance the efficiency of studying genomes, chromosomes and repetitive sequences of C. boreale and subsequently hasten the realization of the genetic scheme of Chrysanthemum.

Floral transition is significant for reproductive products in all flowering plants. However, little is known about the functions of Medicago autonomous pathway gene. We had cloned the FPA gene on Medicago based on the sequence similarity of Arabidopsis FPA sequence. The RT-qPCR analysis of MtFPA expression patterns showed that the MtFPA transcripts accumulated ubiquitously in roots, leaves, stems, flowers, and pods. When fused to the green fluorescence protein, MtPFA-GFP was localized in the nucleus as speckle pattern of protoplast from Arabidopsis. To examine the function of MtFPA, 35S::MtFPA transgenic plants were generated in Arabidopsis late flowering mutant background, fpa-2. Overexpression of MtFPA specifically caused early flowering under long day conditions compared with non-transgenic plants. In MtFPA transgenic lines, AtFLC expression were down-regulated whereas the floral integrators, AtFT and AtSOC1 were up-regulated as compare with control plant. As these results, MtFPA suggest that is a functional ortholog of the Arabidopsis and may play an important role in the regulation of flowering transition in Medicago. *Corresponding Author: Tel. 041-950-0761, E-mail: hjhwang@mabik.re.kr - 229 -
PC-150 Seed color effect on germination rate and antioxidant activity under salt stress in wheat Paulina Calderón Flores, Dae Yeon Kim, Yong Weon Seo * Division of Biotechnology, Korea University, Seongbuk-Gu, Seoul 136-713, KOREA Grain color distinguishes between the pigmentation of the outer layer of the kernel. It is known that environmental factors affects the production of anthocyanins and abiotic stresses like high light intensity, low temperature, high salinity and/or drought stress, and others increase their amounts. After 7 days the germination rate between yellow and dark-purple seeds were almost the same with and without stress (100% yellow seeds under stress and without stress germinated, 93.3% under stress and 96.6% without stress of purple seeds germinated), even though at the final stage the germination was almost the same, we can conclude base on our observations that the germination takes place at a different rate. We think that this might be related to the seed color, since the germination of purple seeds under salt stress started earlier than the yellow ones, until both reached the same point. The antioxidant activity was higher in seedlings from dark-purple seeds than the yellow ones, and they were higher under salt stress than without it, supporting our hypothesis that the purple color in wheat seeds works as a protection under salt stress.

So the control of flowering time is a critical step. In Arabidopsis, expression of certain key flowering gene such as FLOWERING LOCUS C (FLC) is known to be epigenetically regulated by chromatin modification through Enhancer of Zeste[E(z)], a histone methyltransferase, that core component of repressive complex, polycomb repressive complex2(prc2). However, the chromatin mechanism involved in the regulation of rice flowering genes is presently not well known. Here we show that predict coding region of a intronic LncRNA[termed rice COLDAIR(OsCOLDAIR)], which is expected to associate with a component of PRC2, is predicted at rice FLC gene. And additionally we suggest interaction of histone methyltransferase and E3 SUMO ligase that indicate possibility of interaction with rice E(z) gene and rice E3 SUMO ligase. Our study contribute to control of rice flowering time by observing two factor that can regulate expression of related of rice FLC gene. *Corresponding Author: Hak Soo Seo, E-mail: seohs@snu.ac.kr, Ye Jin Kwon, E-mail: yejin0719@snu.ac.kr - 230 -
PC-152 Flowering time is repressed by sumoylation of FLC Jun Soo Kwak 1, Sung-Il Kim 1, Do Youn Kim 1, Ye Jin Gyeon 1, Hak Soo Seo 1,2* 1 Department of Plant Science, Research Institute for Agriculture and Life Sciences, and Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-921, Korea 2 Bio-MAX Institute, Seoul National University, Seoul 151-818, Korea The transition from vegetative growth to flowering is a major developmental switch in the plant cycle and the timing of flowering is very critical for reproduction of plant species. In transition to flowering in plants, Flowering locus C (FLC) is one of the crucial factors. Here, we showed How the stability and activity of FLC are regulated by sumoylation mechanism. By pull-down assay, we showed that FLC interact with E3 SUMO ligase in vitro and vivo. And we showed that FLC is sumoylated in vitro condition with AtSUMO1 protein. In transgenic plants with overexpression of FLC and inducible expression of AtSIZ1, sumo E3 ligase led to increase of FLC protein level and delayed the post-translation degradation of FLC indicating that Arabidopsis E3 sumo ligase AtSIZ1 stabilizes FLC. Also, the plants with overexpression of mutant FLC (K154R, a mutation of the sumoylation site on FLC) flowered considerably earlier than plants with overexpression of FLC but comparable with wild type indicating that sumoylation is a important part for function of FLC. Our data indicate that the sumoylation of FLC is critical for its role in the control of flowering time.

PC-155 Genome-wide transcription profiling of inflorescence development in wheat Dae Yeon Kim 1, Min Jeong Hong 2, Yong Weon Seo 1* 1 Department of Biotechnology, Korea University, Seoul 136-713, Republic of Korea 2 Advanced Radiation Technology Institute, Korea Atomic Energy Research Institute, 29 Geumgu, Jeongeup 580-185, Republic of Korea The control of flowering, transition from vegetative to reproductive stage, is crucial for significant success during plant development. Multiple environmental and developmental signals are transmitted to the shoot apical meristem and converted to local cue to process developmental phage. These crucial process are delicately controlled and regulated by expression of tissue specifically expressed genes involved in inflorescence development. Therefore, it is necessary that molecular mechanism associated with inflorescence development is revealed to understand control of flowering by genome-wide expression pattern of inflorescence specific genes. In this study we used Affymetrix GeneChip Wheat Genome Array for genome-wide analysis of the expressed genes of inflorescence development including apical meristem and developing spikelet to understand the mechanism of floral development in early stage of wheat inflorescence. Moreover, meta-analysis of 1479 microarray dataset of GPL 3802 provided by Gene Expression Omnibus (GEO) was conducted to determine expression pattern of each probe throughout whole life cycle. Based on meta-analysis, we demonstrate inflorescence specific expressed genes in wheat inflorescence including apical meristem, spikelet meristem to understand the mechanism of floral development of wheat inflorescence.

In animal system, DNA methyltransferase with CG methylation activity is modified by SUMO conjugation and then its activity was increased, which means that the activity of DNA methyltransferase is modulated by posttranslational modification. so Chromatin remodeling is a new concept for expression of controlling of gene function. We thus analyzed the effect of E3 SUMO ligase AtSIZ1 in CMT3 (chromometnylase 3)-mediated genome methylation by next-generation sequencing (NGS), methyl binding domain MeDIP-sequencing and gene analysis using siz1-2 and cmt3 mutants. we carried out CG-enrich analysis by MeDIP sequencing revealed that the methylation level of the genome including transposons was significantly low in siz1-2 mutants compared to wild-type. Result showed the genes regulated by methylation, that genes related of embryo and root development, cellulose metabolism, and post-translational modifications. All of our data indicate that the methyltransfearse activity of CMT3 may be able to be regulated by AtSIZ1 and thereby CMT3-mediated gene expression and plant development also can be controlled by E3 SUMO ligase activity. Besides, our data also suggest that ammonium (NH 4 + ) can stimulate AtSIZ1- and CMT3- mediated DNA methylation. *Corresponding Author: Hak Soo Seo, Tel. 010-7378-5036, E-mail: seohs@snu.ac.kr Do Youn Kim, Tel. 010-4786-1991, E-mail: kimdy0202@snu.ac.kr - 234 -

PC-158 The Effects of ehanolic superjami bran extract on glucose and lipid metabolism in ovariectomized rats Su-Jin Nam *, Mi-Young Kang Department of Food Science and Nutrition, Kyungpook National University, Daegu 702-701, Republic of Korea The ovariectomized Sprague-Dawley female rats were randomly assigned to Sham-Control, OVX-Control, OVX-Superjami (extract) groups. The results showed that the activity of glucokinase to keep the blood sugar constant is increased by increasing insulin secretion from pancreatic β- cells and the homeostatic regulation of glucose. Meanwhile the glyconeogenesis which is involved in the actions of the enzymes glucose-6-phosphatase and phosphoenolpyruvate carboxykinase showed that the glucose level is decreased. It was confirmed that these enzymes regulate the carbohydrate metabolism. On the other hand, results of the measurement of the lipid metabolism in the fat tissue and liver tissue, effect of β-oxidation enzymes and carnitine palmitoyl transferase which is involved in fatty acid oxidation for energy generation is increased. Moreover, the activity of fatty acid synthase, glucose-6-phosphate dehydrogenase and malic enzyme have been reduced, therefore, it was confirmed that these enzymes regulate the lipid metabolism. *Corresponding Author: Tel. 053-950-6235, E-mail: say1004625@naver.com PC-159 Repression of DFR1 expression by w3 mutation in Soybean Gyu Tae Park 1, Jagadeesh Sundaramoorthy 1, Jeong-Dong Lee 1, Hak Soo Seo 2,3, Jong Tae Song 1* 1 School of Applied Biosciences, Kyungpook National University, Daegu 702-701, Korea 2 Department of Plant Bioscience, Seoul National University, Seoul 151-742, Korea 3 Bio-MAX Institute, Seoul National University, Seoul 151-818, Korea Soybean [Glycine max (L.) Merr.] have a variety of flower colors which are controlled by six different genes (W1,W2,W3,W4,Wm, and Wp). Among these genes, mutation in W3 gene causes near white flowers in the background of w4 genotype whereas the genotype W3w4 does purple throat flowers. Earlier studies showed that dihydroflavonol 4-reductase1 (DFR1) gene was closely linked to the flower color variants for W3 locus. In order to find out the W3 gene responsible for w3 phenotype, we first, studied the candidate gene Glyma14g07940 (DFR1) which is having 100% similarity with DFR probe sequence. Sequence analysis of DFR1 between W3 and w3 soybeans showed one base substitution in exon 6 of w3 mutant soybean resulting in one amino acid change in the amino acid sequence. However, comparison of amino acid sequences of DFR proteins from various crop plants showed that there is no functional change in the protein. Besides, the promoter analysis showed that, 311 bp of indel was traced in 5 -upstream promoter region of DFR1 gene in the w3 mutant. Here, we show that the near white or purple throat phenotypes in G. max is associated with existence or nonexistence of indel at 5 - upstream promoter region and low or high expression of DFR1, respectively. These results suggest that w3 phenotype may be caused by certain regulator of DFR1 gene located near or distant from DFR1 in G. max. In further study, we need to check the correlation between promoter indel with W3 expression level through GUS analysis.

Adenophora root is mainly used for medicinal purpose. It is effective for lung cleaning, sputum remove, viscera strengthening, cough stopping and cancer treatments. Adenophora has about 70 species in the world and 17 of the species are distributed in Korea. Genetic resources of A. triphylla var. japonica HARA are valuable as the habitat is concentrated in East Asia. The intraspecies variation is very high according to the environmental conditions. A new A. triphylla var. japonica HARA variety, Harang, was developed through polyploid breeding in 2011. But, low domestic production and passive studies caused our country to rely on imports for almost all amount of the A. triphylla var. japonica HARA demands.

However, they also facilitate the ingress of potentially harmful bacterial pathogens. The phytohormone abscisic acid (ABA) plays a pivotal role in protecting plants against biotic stress, by regulating stomatal closure. In the present study, we investigated the mechanism whereby ABA influences plant defense responses to Pseudomonas syringae pv. tomato (Pst) DC3000, which is a virulent bacterial pathogen of Arabidopsis, at the pre-invasive stage. We found that overexpression of two ABA receptors, namely, RCAR4/PYL10-OX and RCAR5/PYL11-OX (hereafter referred to as RCARs), resulted in ABA-hypersensitive phenotypes being exhibited during the seed germination and seedling growth stages. Sensitivity to ABA enhanced the resistance of RCAR4-OX and RCAR5-OX plants to Pst DC3000, through promoting stomatal closure leading to the development of resistance to this bacterial pathogen. Protein phosphatase HAB1 is an important component that is responsible for ABA signaling and which interacts with ABA receptors. We found that hab1 mutants exhibited enhanced resistance to Pst DC3000; moreover, similar to RCAR4-OX and RCAR5-OX plants, this enhanced resistance was correlated with stomatal closure. Taken together, our findings demonstrate that alteration of RCAR4- or RCAR5-HAB1 mediated ABA signaling influences resistance to bacterial pathogens via stomatal regulation. *Corresponding Author: Tel. 02-820-5207, E-mail: sclee1972@cau.ac.kr - 237 -

This plant has been used herbal medicine ingredient in East Asia. Because of the high saponin content, it is an economically important medicinal plant in Korea. It has been reported that saponins of P. grandiflorum were mainly synthesized in root tissues. The studies about root growth of the plant were few. Expansin is an important protein playing a role in root growth of plants, and is known as a nonenzymatic protein. Expansins are novel plant cell wall loosening proteins leading to turgor-driven cell extension. Expansin encoding genes exist in multigene family, and there are more than 30 genes in Arabidopsis thaliana. and more than 50 genes in Oryaza sativa. Therefore, identification of the genes was difficult in P. grandiflorum because of the lack of genome sequence. Recently, the development of next generation sequencing (NGS) technologies make it possible to obtain the target genes sequences rapidly and precisely.

PC-163 Functional roles of the pepper lipoxygenase, CaLOX1, in osmotic, drought, and high salinity tolerance Woonhee Baek, Chanmi Park, Hyunhee Joo, Sung Chul Lee * Department of Life Science, Chung-Ang University, Seoul 156-756, Republic of Korea In plants, lipoxygenases (LOXs) are involved in various physiological processes, including defense responses to biotic and abiotic stresses. Our previous study has shown that pepper 9-LOX gene, CaLOX1, plays a crucial role in cell death due to pathogen infection. Here, the function of CaLOX1 in response to osmotic, drought, and high salinity was examined using CaLOX1-overexpressing (CaLOX1-OX) Arabidopsis plants. Changes in the temporal expression pattern of the CaLOX1 gene were observed when pepper leaves were treated with drought and high salinity, but not with abscisic acid (ABA), the primary hormone in response to drought stress. During seed germination and seedling development, CaLOX1-OX plants were more tolerant to ABA, mannitol, and high salinity than wild-type plants. In contrast, expression of the ABA-responsive marker genes RAB18 and RD29B was higher in CaLOX1-OX Arabidopsis plants than in wild-type plants. In response to high salinity, CaLOX1-OX plants exhibited enhanced tolerance, compared with wild-type, which is accompanied by decreased accumulation of H 2 O 2 and high levels of RD20, RD29A, RD29B, and P5CS gene expressions. Similarly, CaLOX1-OX plants were also more tolerant than wild-type plants to severe drought stress. H 2 O 2 production and relative increase of lipid peroxidation were lower, and the expression of COR15A, DREB2A, RD20, RD29A, and RD29B was higher in CaLOX1-OX plants, relative to those of wild-type plants. Taken together, our results indicate that CaLOX1 plays a crucial role in plant stress responses by modulating the expression of ABA- and stress-responsive marker genes, lipid peroxidation, and H 2 O 2 production. *Corresponding Author: Tel. 02-820-5207, E-mail: sclee1972@cau.ac.kr - 239 -

PC-166 Classification of Celiac disease epitopes of ω-gliadin through data mining and compared with Chinese spring genome sequence Cheol Won Lee, Yong Weon Seo * Department of Biosystems and Biotechnology, Korea University, Seoul 136-713, Republic of Korea Celiac disease (CD) is classified as an autoimmune disease of small intestine and occurred with people with the human leucocyte antigen (HLA) DQ2(8) cells. The gluten commonly called for the gliadins and glutenins from wheat and related proteins from barley and rye is significant cause of celiac disease. There are many sequences that recognized by T-cell according to species and different types of gliadins. In ω-gliadin, two sort of epitopes were figured out that consisting of some proline(p) and glutamine(q) scattered in gliadin sequence. All registered ω-gliadin sequences deposited in NCBI database were downloaded and collected. In order to classify groups depending on sequence difference, sequence similarity and their closeness were analyzed by phylogenetic trees using by MEGA (ver.6.06). Chinese spring genome sequence database offered by URGI (Unité de Recherche Génomique Info) is used for sequence assembly. Primers to validate presence of epitopes were designed by two different type from conserved and specific region. Primer pair from consensus region were designed in conserved domain of ω-gliadin sequences from public database by sequence alignment. And, sequence-specific primers of ω-gliadin were designed from the unique region of each ω-gliadin sequence comparing ω-gliadin sequences from NCBI database with draft sequence of Chinese spring in URGI. The two known epitopes of ω-gliadin were located on same site, approximately from the 315 th nucleotide to the 348 th nucleotide in CDS. Candidate epitopes present in ω-gliadin were divided into three categories based on analysis of sequence similarity. This categorization shows similar pattern with groups that were previously reported by sequence motifs such as SRLL, AREL, ARQL and KELQ.

Plants are capable of integrating photoperiod and ambient temperature signaling into their developmental program. Despite extensive investigations on individual genetic pathways, little is known about the molecular components that integrate both pathways. Here, we demonstrate that the RING finger containing E3 ubiquitin ligase CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) acts as an integrator of photoperiod and ambient temperature signaling. In addition to the role in photoperiodic destabilization of CONSTANS (CO), COP1 also regulates temperature sensitivity by controlling the degradation of GIGANTEA (GI). COP1-impaired mutants showed reduced sensitivity to low ambient temperature. Notably, COP1 is more stabilized at low temperature and accelerates GI turnover in a 26S proteasome-dependent manner. The direct association of GI with the promoter of FLOWERING LOCUS T (FT) depends on ambient temperature, and thus COP1-triggered GI turnover delays flowering at low temperatures via a CO-independent pathway. Taken together, our findings indicate that environmental conditions regulate the stability of COP1, and conditional specificity of its target selection stimulates proper developmental responses and ensures reproductive success. *Corresponding Author: Tel. +82-63-270-3407, E-mail: pjseo1@jbnu.ac.kr - 243 -
PC-168 The pepper RING finger protein CaRING1 plays a role in abscisic acid signaling and drought tolerance Hyunhee Joo, Woonhee Baek, Chanmi Park, Sung Chul Lee * Department of Life Science, Chung-Ang University, Seoul 156-756, Republic of Korea Plants are constantly exposed to a variety of biotic and abiotic stresses, which include pathogens and conditions of high salinity, low temperature, and drought. Abscisic acid (ABA) is a major plant hormone involved in signal transduction pathways that mediate the defense response of plants to abiotic stress. Previously, we isolated Ring finger protein gene (CaRING1)frompepper(Capsicum annuum), which is associated with resistance to bacterial pathogens, accompanied by hypersensitive cell death. Here, we report a new function of the CaRING1 gene product in the ABA-mediated defense responses of plants to drought stress. The expression of the CaRING1 gene was induced in pepper leaves treated with ABA or exposed to drought or NaCl. CaRING1-overexpressing (OX) transgenic plants showed enhanced sensitivity to ABA during the seedling growth and establishment. Furthermore, these plants were more tolerant to drought stress than the wild-type plants because of enhanced stomatal closure and increased expression of stress-responsive genes. Together, these results suggest that the CaRING1 acts as positive factor for drought tolerance in Arabidopsis by modulating ABA-mediated stomatal closing and gene expression. *Corresponding Author: Tel. 02-820-5207, E-mail: sclee1972@cau.ac.kr PC-169 The CabZIP2 pepper pathogen-induced bzip transcription factor positive regulator of disease resistance by promoting PR protein induction Hyunhee Joo, Woonhee Baek, Chanmi Park, Sung Chul Lee * Department of Life Science, Chung-Ang University, Seoul 156-756, Republic of Korea A pepper bzip transcription factor gene, CabZIP2, was isolated from pepper leaves infected with an a virulent strain of Xanthomonas campestris pv. vesicatoria (Xcv). Transient expression analysis of the CabZIP2-GFP fusion protein in Nicotiana benthamiana revealed that the CabZIP2 protein is localized in the cytoplasm as well as the nucleus. The acidic domain in the N-terminal region of CabZIP2 that is fused to the GAL4 DNA-binding domain is required to activate the transcription of reporter genes in yeast. Transcription of CabZIP2 is induced in pepper plants inoculated with virulent or avirulent strains of Xcv. The CabZIP2 gene is also induced by defense-related hormones such as salicylic acid, methyl jasmonate, and ethylene. To elucidate the in vivo function of the CabZIP2 gene in plant defense, virus-induced gene silencing (VIGS) in pepper and overexpression in Arabidopsis were used. CabZIP2-silenced pepper plants were susceptible to infection by the virulent strain of Xcv, which was accompanied by reduced expression of defense-related genes such as CaBPR1 and CaAMP1. CabZIP2 overexpression (OX) in transgenic Arabidopsis plants conferred enhanced resistance to Pseudomonas syringae pv. tomato DC3000. Together, these results suggest that CabZIP2 is involved in bacterial disease resistance. *Corresponding Author: Tel. 02-820-5207, E-mail: sclee1972@cau.ac.kr - 244 -

These rice germplasm, adapted from diverse eco-systems, are undiscovered treasures for rice breeders/ researchers, potentially providing a broad array of useful alleles that enrich gene pools of current cultivated rice varieties. Although growing ex-situ conservation efforts are an important for preserving diverse rice genetic resources, the activity on finding the novel and favorable genetic variants from the vast genebank collection is greatly challenging, requiring extensive screening processes. Therefore, rice core collection is a powerful solution to accelerate utilizations of the exotic germplasm of the entire population. In addition, The application of whole genome re-sequencing technology would establish a potent platform for fast forward genetic study, such as genome wide association study (GWAS). The GWAS has been implemented to efficiently identify candidate genes related to various useful agricultural traits in many crop species including rice. Given the significant associations between genetic variations and phenotypic diversity does not require prior knowledge, GWAS using high genome coverage of SNP markers provides a genomics platform to dissect previously unknown adaptive or other useful genetic variation accumulated in plant germplasm resources over the times. Once pinpointing candidate genes, GWAS allows informed choice of parents for QTL analysis based on the haplotype information, along with suggesting targets for following mutagenesis and transgenics. Here, we are to report our current achievements and perspectives from GWAS and post-gwas undertaken to dissect and exploit useful alleles underlying many agricultural traits from Rice core set, including PHS (Pre-Harvest Sprouting), salt tolerance and disease resistance and so forth. Also, we will introduce the integrated Omics based GWAS case study using transcriptomes, proteomes, metabolomes and ionomes of our rice core set.

It has emerged as a powerful approach for identifying genes underlying complex diseases or morphological traits at an unprecedented rate. Despite benefits, there are only a few examples applied in crop plants due to lack of effective genotyping techniques and well prepared resources for developing high density haplotype maps. In this study, 350 core accessions selected from almost 5,000 Capsicum accessions were used for GWAS. We are planning to construct a high-density haplotype map using GBS platform and perform GWAS for various agronomic traits including fruit traits and metabolites related to pungency to identify genes controlling the traits.

Major cucurbit crops including cucumber (Cucumis sativa), melon (Cucumis melo), watermelon (Citrullus lanatus), and squash/pumpkin (Cucumis pepo) are important in the human diet and the rural economy. In recent years, large amount of genome information has been analyzed and reported in major cucurbit crops, such as cucumber, melon, and watermelon. To construct high quality reference genome sequence of Korean melon (Chamoe), genomic and transcriptomic sequence data were generated from Korean native (Gotgam) and elite (SW3) Chamoe inbred line using Illumina HiSeq2000 platform. In case of genome analysis, 4,773 scaffolds covering 98% of Gotgam Chamoe were assembled through de novo genome assembly and reference-based assembly. Large number of simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs) were detected between two inbred lines and these markers were used for construction of genetic maps and discrimination of cultivars or species. In addition, genome sequence of other Chamoe and melon including Chang Bougi, Sakata s Sweet, Prescott Fond Blanc and Banana melon will be constructed by de novo genome analysis. Genetic markers of these will also be detected and used for marker-assisted breeding and further analysis to investigate major traits of Chamoe, fruit color and flesh color. In conclusion, the newly constructed reference genome will provide genome information for comparative genomics and breeding of other cucurbit crops. - 255 -

Here, we investigated whether sound treatment could delay tomato fruit ripening. We treated harvested tomato fruits with low-frequency sound waves (1 khz) for 6 h, and then monitored various characteristics of the fruits over 14-day period at 23±1 C. Seven days after the treatment, 85% of the treated fruits were green, versus fewer than 50% of the non-treated fruits. Most of the tomato fruits had switched to the red ripening stage by 14 days after treatment. Ethylene production and respiration rate were lower in the treated than non-treated tomatoes. Furthermore, changes in surface color and flesh firmness were delayed in the treated fruits. To investigate how sound wave treatment affects fruit ripening, we analyzed the expression of ethylene-related genes by quantitative real-time RT-PCR analysis. We found that the expression level of several ethylene biosynthetic and ethylene signaling pathway-related genes was influenced by sound wave treatment. These results demonstrate that sound wave treatment delays tomato fruit ripening by altering the expression of important genes in the ethylene biosynthesis and ethylene signaling pathways. *Corresponding Author: Tel. 063-238-4617, E-mail: center1097@korea.kr - 261 -

Conventional genome editing of plant cells using CRISPR/Cas9 technology largely depends on Agrobacterium-mediated transformation of the plant cells and subsequent regeneration of whole plants from the edited cells. During this process, unwanted foreign DNAs including the antibiotics gene and fragments of the T-DNA can be introduced into plant genome. Insertion of these unwanted DNA causes lots of regulatory restrictions when commercializing the LMO products. To step aside these issues, we designed DNA-free ribonucleoprotein-based method and regenerated whole plants from the successfully engineered cells.

PD-01 Soybean germplasm, a rich genetic resource to be explored for the identification of salt tolerance genes and their mechanism of action Sajeesh Kappachery 1, Jagadeesh Sundaramoorthy 1, Gyu Tae Park 1, Jeong-Dong Lee 1, Hak Soo Seo 2,3, Jong Tae Song 1* 1 School of Applied Biosciences, Kyungpook National University, Daegu 702-701, Korea 2 Department of Plant Bioscience, Seoul National University, Seoul 151-742, Korea 3 Bio-MAX Institute, Seoul National University, Seoul 151-818, Korea Soybean germplasm have diverse accessions with great variation in their ability to survive and reproduce under salt stress conditions. In general, cultivated soybeans are more sensitive to salt stress than their wild relatives, however exceptions are found in both the groups. These variations in response to salt stress makes soybean germplasm an interesting collection of genetic resources to be explored for the identification of salt-tolerance genes, and their mechanism of action. Here, in this report we presented a data showing differential response of selected accessions of both cultivated and wild soybeans to salt stress. Two modes of salt treatment; gradual salt stress (GS) as well as salt shock (SS) were used in this study. The GS was found more effective in finding the difference in response of soybean accessions to salt stress. Various genetic marker based methods are in use to identify and isolate the potential genes contributing to the salt tolerance in soybean. Even then there is a paucity of knowledge on the key genes contributing to the salt tolerance in soybean. We expect that a recently developed functional screen based method, like yeast based functional screen, using cdna library generated from different salt tolerant accessions of soybean could lead to identification of novel genes responsible for salt tolerance in soybean. Also, we propose for the use of RNA isolated from different stages of GS and SS for making cdna library to be used for functional screening.

Brassinosteroids (BRs) were found as growth-promoting steroid hormones. Rice, as a monocotyledonous model plants and the major staple crop, has been used to study BR action mechanisms. However, many components of BR pathways and the mechanisms of their molecular interactions have yet to be fully understood. Because the use of the BR biosynthetic inhibitor, Brassinazole (Brz), allowed us to identify important components of BR signaling such as the transcription factor BZR1, we decided to employ a similar strategy to identify novel signaling factors using propiconazole (Pcz), a new potent BR inhibitor. We screened a rice T-DNA mutant population which belongs to Dongjin variety and were developed by the Gene An s group using pga2715 T-DNA vector. Using Pcz treatments we searched for resistant plants, which were reflected on their lengths of roots and/or leaves. We isolated a total of 17 mutant lines, which are being analyzed phenotypically and at molecular level. So far, we have been able to found various lines presenting high or low yield compared to their wild type counterparts. We have found differences in panicle organization of these mutants. Our current experiments include the confirmation of Pcz resistance of these lines and molecular studies involving BR marker genes to understand the relation among yield and BR action in rice. - 267 -
PD-03 Identification and characterization of the novel gene encoding a protein responsible for biosynthesis of DDMP saponin in soybean Jagadeesh Sundaramoorthy 1, Gyu Tae Park 1, Sajeesh Kappachery 1, Jeong-Dong Lee 1, Hak Soo Seo 2,3, Jong Tae Song 1* 1 School of Applied Biosciences, Kyungpook National University, Daegu 702-701, Korea 2 Department of Plant Bioscience, Seoul National University, Seoul 151-742, Korea 3 Bio-MAX Institute, Seoul National University, Seoul 151-818, Korea Soybean [Glycine max (L.) Merr.] seeds are abundant in high-quality proteins and fats. In addition, soybean seeds are also rich in secondary metabolites, such as isoflavones, lecithin, and saponins. Triterpene saponins are major components of these physiologically active metabolites in soybean seeds. Soybean saponins are classified as group A and DDMP saponins. Among them group A saponins are undesirable component of food products due to bitterness and astringency and also cause foaming in tofu production. Whereas, DDMP saponins and their derivatives are less bitter and astringent and beneficial to human health when consumed as regular diet. Therefore, reducing the group A saponins or increasing the DDMP saponins are required to improve the food quality. The present study focused to identify and characterize the gene which is encoding a protein responsible for biosynthesis of DDMP saponins. EMS mutant lines (sg-7-1 & sg-7-2) which lack DDMP saponins were developed. The breeding cross has been made with these two mutants with two cultivars, Pungsannamul and Wooram to study the segregation and genetic linkage analysis, respectively. The segregation analysis showed that the mutant phenotype is controlled by single recessive gene. TLC analysis for phenotyping F 2 population of Wooram X sg-7-1 showed mutant, wild and heterozygous types. To surprise two more patterns were detected and they were named as strange type1 (ST1) and strange type2 (ST2). Further, SSR marker analysis will be carried out to locate the gene which encoding a protein responsible for biosynthesis of DDMP saponins.

PD-04 Small RNA and degradome profiling reveals a role for mirnas and their targets in the regulation of NB-LRR disease resistance genes June Hyun Park 1, Igojo Kang 1, Chanseok Shin 1,2* 1 Department of Agricultural Biotechnology, Seoul National University, Seoul, 151-921, Republic of Korea 2 Plant Genomics and Breeding Institute, Seoul National University, Seoul, 151-921, Republic of Korea MicroRNAs (mirnas) are a class of non-coding RNAs approximately 21-nt in length which play important roles in regulating gene expression in plants. Although many mirna studies have focused on a few model plants, mirnas and their target genes remain largely unknown in hot pepper (Capsicum annuum), one of the most important crops cultivated worldwide. We here employed high-throughput small-rna and degradome sequencing to comprehensively identify small-rnas and their targets in pepper. From these, we identified several novel targets of mirnas, including the major de novo methylation enzyme involved in RNA-directed DNA methylation in plants. Furthermore, we identified several highly abundant 22-nt mirna families that target conserved domains in NB-LRRs and trigger the production of phased secondary sirnas. We showed that transient co-expression of can-mir482 with Rpi-blb1, one of the potato NB-LRRs, resulted in the attenuation of the hypersenstive responses in Nicotiana benthamiana, suggesting that interaction between mir-482 family and disease resistance proteins is likely to serve as a conserved trigger for defense mechanism in Solanaceae. This work provides the first reliable draft of the pepper small RNA transcriptome that offers an expanded picture of mirnas in relation to NB-LRR regulation, providing a basis for understanding the functional roles of mirnas in disease resistance pepper.

Although ETI is often associated with the hypersensitive response (HR), various R genes mediate an HR-independent process known as extreme resistance (ER). In the soybean-soybean mosaic virus (SMV) pathosystem, the strain-specific CI protein of SMV functions as an effector of Rsv3-mediated ER. In this study, we used the soybean (Rsv3)-SMV (CI) pathosystem to gain insight into the molecular signaling pathway involved in ER. We used genome-wide transcriptome analysis to identify a subset of the type 2C protein phophatase (PP2C) genes that are specifically up-regulated in Rsv3-mediated ER. Gain-of-function analysis of the most significantly expressed soybean PP2C gene, GmPP2C3a, showed that ABA-induced GmPP2C3a functions as a key regulator of Rsv3-mediated ER.

Dae Yeon Kim, Oonha Shin, Yong Weon Seo * Department of Biotechnology, Korea University, Seoul 136-713, Republic of Korea Nutritious and functional foods from crop have received great attention in recent years. Colored-grain wheat contains high phenolic compound and a large number of flavonoid. One of plant pigments, wheat anthocyanin is increasingly emerging as natural compounds for consumer s health and condition. Red grains and white grains with different antioxidant activity was used to conduct germination assay. Antioxidant enzyme assay of POD, APX, CAT, GST, GR and GPx was conducted during the imbibitional phase of mature seeds. Malondialdehyde (MDA) content was analyzed to assess the activity of ROS during imbibition phase of mature seeds and alpha-amylase contents were quantified for 3 days during dark imbibition. Additionally, sprouting rates of developing seeds in spikelet after anthesis with damp condition were measured in each red grain groups for two weeks to evaluate sprout ability affected by phytochemical of red grain wheat. In summary, we identified that red grain wheat showed higher antioxidant enzyme activity involved in ROS scavenging during imbibition. Sprouting rate during dark imbibition in developmental spikelet of four groups classified by color suggest that phytochemicals in dark red grain wheat caused negative effects to sprouting.

Among morphological traits, stem growth habit, the presence of awn in spikelet, and autumn new shoot are the most important key traits enabling to cluster Miscanthus accessions into M. sinensis and M. sacchariflorus groups. Miscanthus sinensis has bunch stem growth habit and awn in spikelet, and produces autumn new shoot, while M. sacchariflorus has scattering stem growth habit with no awn in spikelet and does not produce autumn new shoot. Interestingly, we found several Miscanthus accessions showing intermediate morphological traits. 7 M. sinensis accessions showed morphological traits similar to M. sacchariflorus and 17 M. sacchariflorus accessions showed morphological traits similar to M. sinensis. Flow cytometry and chromosome counting finally revealed 5 Miscanthus hybrids, suggesting that they are resulted from natural hybridization between M. sinensis and M. sacchariflorus. Therefore, these Miscanthus hybrids can be used to understand genetic recombination between these two Miscanthus species and our understanding may support future efforts for breeding new Miscanthus variety with high biomass productivity and environmental adaptability. *Corresponding Author: Tel. 02-880-4542, E-mail: dosoonkim@snu.ac.kr - 273 -
PD-12 Complete chloroplast genomes of two Miscanthus species Gyoungju Nah *, Ji-Hoon Im, Soo-Hyun Lim, Kyunghee Kim, Do-Soon Kim * Department of Plant Science, Research Institute of Agriculture and Life Sciences, College of Agriculture and Life Sciences, Seoul National University, Seoul 151-921, Korea The complete chloroplast (cp) genomes of two Miscanthus species, M. sinensis and M. sacchariflorus, were sequenced and investigated for genes, genome size variation, and polymorphisms. There are 154 genes in both cp genomes, consisting of 122 coding genes, 40 trna genes, and 8 rrna genes. The cp genome contains two inverted repeat (IR) regions, separated by large single copy (LSC) region and small single copy (SSC) region. 112bp indels in M. sinensis and 152bp in M. sacchariflorus were found mainly in LSC and SSC, which are responsible for 40 bp-difference in cp genome size in two species. Likewise, out of 94bp of SNPs, 88bp were found in LSC and SSC regions. Although gene number and sequence structure were quite well conserved, indel distribution and size were different in these two Miscanthus species. *Corresponding Author: Tel. 02-880-4542, E-mail: dosoonkim@snu.ac.kr PD-13 Quantitative shotgun proteomic analysis of rice anther under the cold stress Joohyun Lee *, Mijeong Kim, Yoonjung Lee Department of Applied Bioscience, Konkuk, University, Seoul 143-701, Republic of Korea In rice, the stage of the meiosis in the pollen is sensitive stage resulted in the pollen sterility to reduce yield.

PD-15 E3 SUMO ligase AtSIZ1 regulates the amounts of nutrient reservoir cruciferins in Arabidopsis thaliana seed. Sung-Il Kim 1, Joo Yong Kim 1, Do youn Kim 1, Ye Jin Gyeon 1, Jun Soo Kwak 1, Hak Soo Seo 1,2* 1 Department of Plant Science, Research Institute for Agriculture and Life Sciences, and Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-921, Korea 2 Bio-MAX Institute, Seoul National University, Seoul 151-818, Korea Arabidopsis E3 SUMO ligase SIZ1 (AtSIZ1) controls vegetative growth and development including responses to nutrient deficiency and environment stresses. Here, we analyzed the effect of AtSIZ1 on the stability and amount of seed proteins. Proteomic analysis showed that the amount of three major nutrient reservoir proteins, CRUCIFERIN (CRU) 1, 2 and 3, were decreased in siz1-2 mutants. However, quantitative real-time RT-PCR showed that transcript levels of CRU1, 2 and 3 genes were rather significantly higher in siz1-2 mutants than wild-type plants. Yeast two hybrid analysis revealed that AtSIZ1 interacts with CRU1, CRU2 and CRU3, strongly suggesting that CRU1, 2 and 3 proteins are sumoylated by AtSIZ1. In addition, the analysis of amino acid composition by HPLC showed that the contents of amino acids were a bit high in siz1-2 mutants. Our data indicate that AtSIZ1 plays an important function for accumulation of seed storage proteins through its ligase activity.

However, the complexity of genome, such as genome duplication, limits the utility of genome-wide association studies and linkage analyses to identify genes controlling yield traits. We propose the variation block method, a three-step process for recombination block detection and comparison. The first step is to detect variations by comparing short-read DNA sequences of the cultivar to a reference genome of the target crop. Next, sequence blocks with variation patterns are examined and defined. The boundaries between the variation-containing sequence blocks are regarded as recombination sites. All the assumed recombination sites in the cultivar set are used to split the genomes, and the resulting sequence regions are named as variation blocks. The practicality of this approach was demonstrated by the identification of a putative locus determining soybean hilum color and known genes such as flower color gene. We suggest that the variation block method is an efficient genomics method for recombination block-level comparison of crop genomes. We expect that this method holds the prospect of developing crop genomics by bringing genomics technology to the field of crop breeding. *Corresponding Author: Tel. 033-330-1840, E-mail: kimyuh77@korea.kr - 277 -
PD-18 Overexpression of the Arabidopsis vacuolar H + -pyrophosphatase AVP1 gene in rice plants improves grain yield under paddy field conditions Il-Sup Kim 1*, Young-Saeng Kim 2, Yul-Ho Kim 3, Hyang-Mi Park 3, Ho-Sung Yoon 1 1 Department of Biology, Kyungpook National University, Daegu 702-701, Republic of Korea 2 Division of Biological Sciences, University of California San Diego, La Jolla, California 92093-0116, USA 3 National Institute of Crop Science, Rural Development Administration, Suwon 441-857, Republic of Korea The Arabidopsis gene AVP1 encodes a vacuolar H + -translocating inorganic pyrophosphatase (EC3.6.1.1) that functions as an electronic proton pump in the vacuolar membrane and affects growth development and stress responses in plants. This study was conducted to evaluate the molecular properties of the A. thaliana vacuolar H + -pyrophosphatase (AVP1) gene in rice. Incorporation and expression of the transgene was confirmed by PCR and quantitative real-time PCR, respectively. Expression of the AVP1 gene in transgenic rice plants (TRP1 and TRP2) resulted in significantly enhanced tolerance to 100 mm NaCl under greenhouse conditions when compared to control wild-type (WT) rice plants. Augmented AVP1 expression in the transgenic rice plants also affected total biomass and improved ion homeostasis through increased accumulation of Na + ions in whole tissues when compared to control WT rice plants under high salinity conditions. The Fv/Fm values of transgenic rice plants were higher than those of WT rice plants, even though the values decreased over time in both WT and transgenic (TRP1 to TRP8) rice plants. Furthermore, rice grain yield and biomass of the transgenic rice plants were at least 15% higher based on the culm and root weights and panicle and spikelet numbers when compared to those of the WT rice plants during the farming season in Korea. Thus, these results suggest that ectopic AVP1 expression conferred tolerance and stress resistance to genetically modified transgenic crop plants by improving cellular ion homeostasis against salt conditions, which enhanced the rice yield and biomass under natural conditions in paddy fields. *Corresponding Author: Tel. 053-950-5348, E-mail: 92kis@hanmail.net PD-19 SNP 마커를이용한고추의적색소함량연관 QTL mapping 김정호 *, 안율균, 이혜은, 김진희, 김도선, 조명철, Sandeep Karna 전라북도완주군이서면농생명로 100 국립원예특작과학원채소과 고추의적색소는고추의상품성을가늠하는중요한척도이면서식재료뿐아니라상업적으로도다양하게활용되고있다. 본연구는적색소성분의함량과관계하는 QTL 마커를개발하기위하여적색소성분분석을위한 mapping 집단을육성하였고, 적색소성분에대한 QTL mapping 을수행하였다. 적색소분석을위한 mapping 집단인 만다린 과 블랙클러스터 를양친으로하는 F 7 RIL 집단에서의색도 (ASTA value) 분포는 1.64 에서 117.26 의범주에있으며그분포양상은정규분포를보여 QTL 분석에적합한것으로확인되었다.Mapping 집단의양친들에대해서 454 GS-FLX pyrosequencing 을이용한 NGS 를수행하였고, 그결과 만다린 과 블랙클러스터 각각 120.44Mb 와 142.54Mb 의염기서열데이터를확보할수있었으며, 만다린 에서 1,025 개, 블랙클러스터 에서 1,059 개의 SNP 들을확보하게되었다. 이 SNP 들을 HRM 분석에용이하도록프라이머를제작하여유전자지도작성을수행한결과총 246 개의 SNP 마커를이용하여약 512cM 을설명할수있는 21 개연관군의유전자지도가작성되었다. 분석집단 93 계통들에서측정된 ASTA 값을이용하여수행한 QTL 분석결과총 6 개의 QTL 을확인하였다. 이들 QTL 과근접한마커들은향후고추의적색소함량연구에매우유용한정보로활용될것이며, 아직까지개발된바없는적색소함량연관마커개발에가능성을열어줄것으로기대한다. * 주저자 : Tel. 063-238-6673, E-mail: gogh1221@gmail.com - 278 -
PD-20 Identification of modulatory elements in xylem development for biomass production Jinu Kim 1, Hwi Seong Jeon 1, Hong Joo Cho 1, Soon Il Kwon 1, Young Hoon Jung 1, Jae-Soon Lee 2, Eun Woon Noh 2, Kyoung Heon Kim 1, Ohkmae K. Park 1 1 Korea University 2 Korea Forest Research Institute The vascular system of plants consists of two conducting tissues, xylem and phloem, which differentiate from procambium cells. Xylem serves as a transporting system for water and signaling molecules and is formed by sequential developmental processes, including cell division/expansion, secondary cell wall deposition, vacuole collapse, and programmed cell death (PCD). PCD during xylem differentiation is accomplished by degradation of cytoplasmic constituents, and it is required for the formation of hollow vessels, known as tracheary elements (TEs). Our recent study revealed that the small GTPase RabG3b acts as a regulator of TE differentiation through its autophagic activation. By using an Arabidopsis in vitro cell culture system, we showed that autophagy is activated during TE differentiation. Overexpression of a constitutively active RabG3b (RabG3bCA) significantly enhances both autophagy and TE differentiation, which are consistently suppressed in transgenic plants overexpressing a dominant negative form (RabG3bDN) or RabG3bRNAi (RabG3bRNAi), a brassinosteroidinsensitive mutant bri1-301, and an autophagy mutant atg5-1. Wood (called secondary xylem) is the most abundant biomass produced by land plants including Populus and Eucalyptus, and therefore is considered to be one of the most cost-effective and renewable bioenergy resources. In an attempt to enhance xylem differentiation and thus to improve biomass traits in poplars, we generated transgenic poplars overexpressing the RabG3bCA form. As notable phenotypes, both stem height and diameter were increased and xylem area in vascular bundles was significantly expanded in RabG3bCA transgenic poplars compared to control plants. Taken together, these results demonstrate that RabG3b regulates xylem differentiation in both Arabidopsis and Populus. This study enhances our understanding of biological mechanisms underlying wood formation and serve as a framework to engineer the quality and quantity of wood as useful biomass.

PD-22 Cloning and functional characterization of an acyl-acp thioesterase (CvFatB) from Cuphea viscosissima in Arabidopsis Kyung Hee Roh *, Han-chul Kang, Jong-Bum Kim, Hyun Uk Kim, Kyeong-Ryeol Lee Department of Agricultural Biotechnology, National Academy of Agricultural Science, RDA, Jeonju 560-500, Republic of Korea Acyl-acyl carrier protein (ACP) thioesterase (TE) catalyze the hydrolysis of the thioester bond that links the acyl chain to the sulfhydryl group of the phosphopantetheine prosthetic group of ACP. This reaction terminates acyl chain elongation of fatty acid biosynthesis, and in plant seeds it is the biochemical determinant of the fatty acid compositions of storage lipids. A full-length cdna of an acyl-acp thioesterase, named CvFatB, was isolated from oil plant Cuphea viscosissima accumulating up to 90% caprylate (8:0) and caprate (10:0) in its seed oil. This cdna contains a 1,245-bp open reading frame that encodes a protein of 415 amino acids. The deduced sequence also contains two essential residues (H 317 and C 352 ) for TE catalytic activity and a putative chloroplast transit peptide at the N-terminal. Overexpression of the CvFatB cdna in Arabidopsis resulted in increased levels of saturated fatty acid, especially palmitate, and reduced levels of unsaturated fatty acids. The findings suggest that CvFatB from oil plant C. viscosissima can function as a saturated acyl-acp TE and can potentially be used to diversify the fatty acid biosynthesis pathway to produce novel fatty acids. *Corresponding Author: Tel. 063-238-4606, Email: rohkh@korea.kr PD-23 The influence of silver thiosulfate and thidiazuron on shoot regeneration from cotyledon explants of Brassica napus Kyung Hee Roh *, Han-chul Kang, Jong-Bum Kim, Hyun Uk Kim, Kyeong-Ryeol Lee Department of Agricultural Biotechnology, National Academy of Agricultural Science, RDA, Jeonju 560-500, Republic of Korea The influences of ethylene inhibitors (AgNO3 and silver thiosulfate) and cytokinins (BAP and TDZ) on shoot regeneration from cotyledon and hypocotyl explants of B. napus cv. Youngsan were investigated. The presence of 50 μm Silver thiosulfate (STS) in shoot regeneration medium formed shoots at 60-68% after 3-4 weeks of culture, which was enhanced by 2-fold compared to that of Silver nitrate (AgNO3). Moreover, cotyledon explants were more regenerative than hypocotyls; shoots from cotyledon explants began to occur 4-5 days earlier than that of hypocotyl explants. TDZ at a concentration of 8-10 μm was effective for shoot regeneration, compared with BAP. Consequently, the optimal shoot regeneration response was observed in medium supplemented with 50 μm STS + 8 μm TDZ. In transmission electron microscopy (TEM) analysis, higher density of silver nanoparticles was shown to be accumulated widely inside the cell wall and plasmodesmata of regenerating leaf cultured in medium supplemented with AgNO3. By contrast, in the cell cultured in medium with STS, fine-grained deposits were partly observed in the surroundings of the cell wall. *Corresponding Author: Tel. 063-238-4606, Email: rohkh@korea.kr - 280 -
PD-24 A review on change in plant proteome following biotic stress. R. Krishna, Ravi Gupta, Chul Woo Min, So Wun Kim, Sun Tae Kim Department of Plant Bioscience, Pusan National University, Miryang, Korea Different biotic agents such as bacteria, fungi, nematode and virus interact with plants, and causes significant annual crop loss. The plants interact with these pathogen and undergo various changes at physiological, biochemical and molecular levels. The omics technique is a powerful way which provides important information related to molecular changes occurring during plant-pathogen interaction. Several studies have been conducted and revealed either up or down-regulation of many genes involved in metabolism, energy, photosynthesis, signaling, defense and ROS upon pathogen interaction. In this review, we highlight recent progress in proteomic studies of plant-pathogen interaction, which could be useful for controlling disease and development of molecular markers for early detection of different diseases.

PD-26 Searching For Transcription Factors Involved In Ammonium Assimilation and Root Growth in Rice Plants Ryza A. Priatama, Vikranth Kumar, Jin-hee Jeong, Chang-deok Han Division of Applied Life Science, Plant Molecular Biology & Biotechnology Research Center (PMBBRC), Gyeongsang National University, Jinju 660-701, Korea Nitrogen in rice paddy soils and utilized as the major source for N-assimilation in rice crops. In roots, transcriptional activities of ammonium uptake and assimilation genes are highly sensitive to the availability of exogenous ammonium. However, little is known about the transcription factor genes that regulated by ammonium supply and its role to roots and plant developments. To study the transcription factor genes that involved in Ammonium response, two weeks old rice seedlings treated using Ammonium from 0 to 3 hours. Total RNA collected from each sample and samples were prepared for Agilent 8x60K microarray system. Based on the microarray data, we select transcription factor genes that highly affected by ammonium and selected knock out mutant candidates that used for phenotype screening. PD-27 MSP1 triggers cell death and defense response in rice Qingfeng Meng 1, Yiming Wang 2, Kyu Young Kang 3, Ravi Gupta 1, Sun Tae Kim 1 1 Department of Plant Bioscience, Pusan National University, Miryang, Korea 2 Department of Plant Microbe Interactions, Max Planck Institute for Plant Breeding Research, Carl-von-Linne Weg 10, Cologne, 50829, Germany 3 Plant Molecular Biology and Biotechnology Research Center, Gyeongsang National University, Jinju, Korea When the rice blast fungus attacks rice, fungal proteins are secreted into the plant apoplast to facilitate infection. The rice plant recognizes such secreted proteins, which result in the induction of defense responses. However, the molecular mechanisms of how rice plant recognizes secreted proteins remain elusive. Here, we report that a small, secreted protein, Magnaporthe oryzae snodprot1 homolog (MSP1), is recognized by rice plants and triggers host cell death and defense responses. Furthermore, pre-treatment of rice with Domain II, elicitor-active epitope of MSP1, induces resistance to the pathogen KJ301. We demonstrated that secretion of MSP1 into the apoplast is prerequisite for triggering cell death and activating defense-related gene expression, suggesting that it is recognized by a receptor in the host plasma membrane. Through comprehensively analysis of transcriptional profile in rice leaves and suspension cultured cells (SCCs) in response to exogenous MSP1 and Domain II treatment using 60K Agilent microarray chip, we found that 27 signaling genes, such as F-box(6), MAPK(4), protein kinase(11), transcription factor(6), were up-regulated in leaves and SCCs and six protein kinases were targeted into plasma membrane. Thus, we suggest that some of these genes may act as receptor of MSP1 in response to exogenous MSP1 treatment. Expression pattern of candidate genes was further checked in response to different environment cues using open rice data. These results demonstrate that these genes may be also involved in the signaling in response to cold stress, root-ja treatment and brown plant hopper (BPH) attack. - 282 -

A mutant named Coiled Branch 1 (cbr1), is found to have a wavy and curly morphology with coiling branches. Plasmid rescue and genomic southern blot analysis revealed the site of T-DNA insertion in the genome. RT-PCR was performed to monitor expression levels of the genes adjacent to the T-DNA integration sites, and showed the activation of an E3 ubiquitin ligase gene. Database search showed that the gene with the RING domain belongs to a family of E3 ubiquitin ligases. Complementation test by overexpression and RNA interference of the gene was also carried out. The complementation test results showed that the novel gene activation tagging affected the cbr1 mutant phenotypes. Ubiquitylation has been linked virtually to every cellular process including plant development. E3 ubiquitin ligase has been reported to recognize target proteins that are to be ubiquinated for further degradation by the proteasome complex. Further, more detailed studies are needed to identify the specific substrate(s) of the novel E3 ubiquitin ligase gene.

PD-29 Self-directed control of the diurnal CONSTANS dynamics in Arabidopsis photoperiodic flowering Mi-Jeong Park 1, Young-Ju Kwon 1, Kyung-Eun Gil 1, Pil Joon Seo 2, Jae-Hoon Jung 3, Chung-Mo Park 1,4* 1 Department of Chemistry, Seoul National University, Seoul 151-742, Korea 2 Department of Bioactive Material Sciences and Research Center of Bioactive Materials, Chonbuk National University, Jeonju 561-756, Korea 3 Sainsbury Laboratory, University of Cambridge, Cambridge CB2 1LR, UK 4 Plant Genomics and Breeding Institute, Seoul National University, Seoul 151-742, Korea The circadian clock control of CONSTANS (CO) transcription and the light regulation of CO stability coordinately regulate photoperiodic flowering by triggering rhythmic expression of the floral integrator FLOWERING LOCUS T (FT). The diurnal pattern of CO accumulation is modulated sequentially by distinct E3 ubiquitin ligases, such as HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENES 1 (HOS1) in the morning, FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 (FKF1) in late afternoon, and CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) at night. In particular, CO is stabilized by FKF1 in late afternoon only under long days. Here, we show that CO abundance is not simply regulated by the E3 enzymes in a passive manner but also self-regulated actively through dynamic interactions between two CO isoforms. CO alternative splicing produces two protein variants, the full-size COa and the C-terminally truncated COb. Notably, COb, which is resistant to the E3 enzymes, induces the interactions of COa with CO-destabilizing HOS1 and COP1 but inhibits the association of COa with CO-stabilizing FKF1. These observations demonstrate that CO plays an active role in sustaining its diurnal accumulation dynamics in Arabidopsis photoperiodic flowering. *Corresponding Author: Tel. 02-880-6640, E-mail: cmpark@snu.ac.kr PD-30 CaLEA1 is a late embryogenesis abundant protein in pepper that positively regulates abscisic acid signaling, drought and salt stress response Chanmi Park, Hyunhee Joo, Woonhee Baek, Sung Chul Lee * Department of Life Science, Chung-Ang University, Seoul 156-756, Republic of Korea Drought and high salinity are the most important abiotic factors limiting plant development, growth, and crop productivity in agriculture (Munns and Tester 2008, Sengupta and Majumder 2009, Zhu 2002). As sessile organisms, plants are frequently exposed to drought and high salinity conditions, which alter water potential and cause osmotic stress, leading to serious damage to plant tissues (Bartels and Sunkar 2005, Boudsocq and Lauriere 2005). During exposure to water stress, plants display many physiological changes, such as reduction of water content, closure of stomata, and decreased cell enlargement and growth. In addition, severe and continuous water stress in plants causes the cessation of photosynthesis and disturbance of metabolism, and finally results in death (Nath et al. 2005, Shao et al. 2008). To adapt to these abiotic stress conditions, plants show a variety of responses, including the accumulation of abscisic acid (ABA) and expression of a large number of stress-related proteins (Krasensky and Jonak 2012, Lee and Luan 2012, Skriver and Mundy 1990, Stewart and Lee 1974). Although the cellular and molecular responses to environmental stress are well studied (Hasegawa et al. 2000, Thomashow 1999), the mechanisms underlying the functional modifications caused by osmotic stress are yet to be clarified, because of the complexity at the cellular level as well as at the whole plant level (Ashraf and Harris 2004, Flowers 2004, Foolad et al. 2003a, 2003b, Xiong et al. 2002). *Corresponding Author: Tel. 02-820-5207, E-mail: sclee1972@cau.ac.kr - 284 -
PD-31 The putative E3 ubiquitin ligase CaAIR1 in pepper regulates abscisic acid signaling and drought stress response Chanmi Park, Hyunhee Joo, Woonhee Baek, Sung Chul Lee * Department of Life Science, Chung-Ang University, Seoul 156-756, Republic of Korea Several E3 ubiquitin ligases have been associated with the response to abiotic and biotic stresses in higher plants. Here, we report that the hot pepper (Capsicumannuum) abscisic acid (ABA)-InsensitiveRINGprotein1gene(CaAIR1) is essential for a hypersensitive response to drought stress. CaAIR1 contains a C3HC4-type RING finger motif, which plays a role for attachment of ubiquitins to the target protein, and a putative transmembrane domain. The expression levels of CaAIR1 are upregulated in pepper leaves by ABA treatments, drought, and NaCl, suggesting its role in the response to abiotic stress. Our analysis showed that CaAIR1 displays self-ubiquitination and localized in the nucleus. We generated CaAIR1-silenced peppers via virus-induced gene silencing (VIGS) and CaAIR1-overexpressing (OX) transgenic Arabidopsis plants to evaluate their responses to ABA and drought. VIGS of CaAIR1 in pepper plants conferred an enhanced tolerance to drought stress, which was accompanied by low levels of transpirational water loss in the drought-treated leaves. CaAIR1-OX plants displayed an impaired sensitivity to ABA during seed germination, seedling, and adult stages. Moreover, these plants showed enhanced sensitivity to drought stress because of reduced stomatal closure and decreased expression of stress-responsive genes. Thus, our data indicate that CaAIR1 is a negative regulator of the ABA-mediated drought-stress tolerance mechanism. *Corresponding Author: Tel. 02-820-5207, E-mail: sclee1972@cau.ac.kr PD-32 Comparative transcriptome analysis of tolerant rice mutant and its wild type in response to arsenate stress Hyeon Mi Park, Sun-Goo Hwang, Cheol Seong Jang * Plant Genomics Lab., Department of Applied Plant Sciences, Kangwon National University, Chuncheon 200-713, Republic of Korea Arsenic (As) is accumulated in rice grain due to environmental reasons such as polluted ground water and soil, and As toxicity constitutes a serious threat to human health. However, the accurate information required for understanding As-responsive mechanisms remain mostly unknown in rice. Here, we performed the comparative genome-wide transcriptome analysis between As tolerance type (ATT) rice mutant induced by γ-irradiation and its wild type (WT). As compared to WT after As treatment of 150 ppm, ATT exhibited the phenotypic differences such as vigorous growth in shoots and root hairs, and low accumulation of H 2 O 2 in rice roots. In transcriptome analysis, we found between WT and ATT that As toxicity commonly affected to inhibit gene regulations involved in photosynthesis, mitochondrial electron transport and lipid biosynthesis metabolism. While, many genes associated with cysteine synthesis metabolism considerably up regulated in both As-treated plants. Additionally, we found the potential As tolerance-related genes involved in abiotic stress-responsive mechanism and RNA-protein synthesis for protein degradation and modification. To further analyzes the genetic variations of As-responsive genes, the DNA polymorphic DEGs associated with oxidoreductase significantly distributed in ATT more than in WT. *Corresponding Author: Tel. 033-250-6416, E-mail: sjang@kangwon.ac.kr - 285 -
PD-33 Mutation of SPOTTED LEAF3 (SPL3) impairs abscisic acid-responsive signaling and delays leaf senescence in rice Seung-Hyun Wang, Jung-Hyun Lim, Yasuhito Sakuraba, Nam-Chon Paek * Department of Plant Science, Plant Genomics and Breeding Institute, and Research Institute of Agriculture and Life Sciences, Seoul National University, Seoul 151-921, Korea. Lesion mimic mutants commonly display spontaneous cell death in pre-senescent green leaves under normal conditions, without pathogen attack. Despite molecular and phenotypic characterization of several lesion mimic mutants, the mechanisms of the spontaneous formation of cell death lesions remain largely unknown. Here, we examined the rice lesion mimic mutant spotted leaf3 (spl3). In mutants grown under a light/dark cycle, spl3 mutants appeared similar to wild type at early developmental stages, but lesions gradually appeared in the mature leaves close to heading stage. By contrast, in mutants grown under continuous light, severe cell death lesions formed in developing leaves, even at the seedling stage. Histochemical analysis showed that hydrogen peroxide accumulated in the mutants, likely causing the cell death phenotype. By map-based cloning and complementation, we showed that a 1-bp deletion in the first exon of Oryza sativa Mitogen-Activated Protein Kinase Kinase Kinase1 (OsMAPKKK1)/OsEDR1/ OsACDR1 causes the spl3 mutant phenotype. We found that the spl3 mutants were insensitive to abscisic acid (ABA), showing normal root growth in ABA-containing media and delayed leaf yellowing during dark-induced and natural senescence. Expression of ABA signaling-associated genes was also less responsive to ABA treatment in the mutants. Furthermore, the spl3 mutants had lower transcript levels and activities of catalases, which scavenge hydrogen peroxide, probably due to impairment of ABA-responsive signaling. Finally we discuss a possible molecular mechanism of lesion formation in the mature leaves of spl3 mutants.

In rice, tiller number is one of the important biomass and yield components. A maize mutant grassy tillers1 (gt1) increases lateral branches in maize. The GT1 gene encodes a class I homeodomain leucine zipper (HD-Zip) protein. In maize, the gt1 expression is induced by shading and is dependent on the activity of teosinte branched1 (tb1), a major domestication locus controlling tillering and lateral branching. To estimate the biological role and agricultural utility of gt1 in rice, rice homologue (OsGT1) has been isolated and its overexpressors and RNAi lines were generated. Field data showed that OsGT1 overexpressors reduced tillers and panicles while RNAi lines increased them, compared to wild type. Shade signal is an important factor in determining lateral branching. To understand the relationship between OsGT1 and shade avoidance, plants have been grown under 50% shading in the field. Also, double genetic combinations with phytochrome mutants (phya, B, and C) are being examining for tillering phenotype. These ongoing researches will provide insights in determining the action of OsGT1 on branching and shade avoidance in rice. - 286 -

Due to these complexity, wheat genome study is a large challenge to researchers for genomic and genetic study. We analyzed expressions of individual wheat genome and rye genome specific transcripts using custom array with 2BS.2RL wheat-rye translcoation. Genomic probes were synthesized within each diploid progenitors (AA, BB, DD, 2n = 14, respectively) of wheat, common wheat, and rye (RR, 2n = 14). Total RNA isolated from seedlings of T. urartu, Ae. speltoides, Ae. squarrosa, Chinese Spring, Chaupon, and 2BS.2RL were hybridized on arrays. Each homoeologous gene differentially expressed in hexaploid wheat and rye were identified on the custom array and the transcripts were clustered based on hybridization values. qrt-pcr was performed to verify the custom array result with a set of five genes by highly replicated experiments (three biological and three technical replications). The qrt-pcr results demonstrated genome specific expression of five genes in sympathy with array results. Here we provide information of each individual genome specific transcripts and it will we a useful data to study complex wheat genome compositions.

PD-36 Global investigation of small RNA expression on nutrient stress responses provides information on nutrient-responsive micrornas involved in crop productivity Sang-Yoon Shin 2, Dooyoung Lee 1, Ju-Kon Kim 3, Chanseok Shin 1,2* 1 Department of Agricultural Biotechnology, Seoul National University, Seoul 151-921, Republic of Korea 2 Interdisciplinary Program in Agricultural Genomics, Seoul National University, Seoul 151-921, Republic of Korea 3 Seed Biotechnology Institute, Green Bio Science and Technology, Seoul National University, Pyeongchang-gun, Kangwon-do, Republic of Korea Nitrogen is a key component in the growth of crop plant. To increase the yield of crops, an enormous amount of nitrogen fertilizer is currently being used, which increases the total production cost and leads to environmental pollution by the residual nitrogen sources. For these reasons, researchers have tried to improve the crop s nitrogen use efficiency (NUE) as a solution for reducing the amount of nitrogen fertilizer used. MicroRNAs are a class of small non-coding RNAs regulating the expression of target genes. Recent studies suggested that the expression pool of micrornas changes in response to a variety of nutrient deficiencies and that such changes play important roles in adapting to or resisting the consequential nutritional stresses. Here, we aim to identify and characterize rice micrornas whose expression changes upon nitrogen starvation and re-supplementation. By applying RNA-Seq, we observed that the expression of a set of genes involved in nitrogen assimilation was altered in response to nitrogen deprivation. We also found that a considerable number of micrornas exhibited dynamic expression changes in a nitrogen supply state-dependent manner and that the expression of genes targeted by those differentially regulated micrornas was altered reciprocally. Our study suggests that micrornas may have roles in regulating the response of rice to nitrogen supply state and subsequently modulating NUE.

PD-37 OsVIL genes, which encode PRC2 chromatin remodeling factors, may be used for improving grain yield by increasing biomass in rice. Jung-Il Yang, Hee Joong Jeong, Lae-Hyeon Cho, Jinmi Yoon, Gynheung An * Graduate School of Biotechnology & Crop Biotech Institute, Kyung Hee University, Yongin, 446-701, Republic of Korea Post-translational modifications of nucleosomal core histones play important roles in biological processes via altering chromatin structure and creating target sites for proteins acting on chromatin. Molecular genetic studies with Arabidopsis have verified several epigenetic factors that regulate flowering time. However, the roles of chromatin remodeling factors have not been well explored in rice. Here, we identified chromatin remodeling factors, OsVIL1, 2, and 4 (Oryza sativa VIN3-LIKE) genes, that regulate grain yield. OsVIL proteins contain a plant homeodomain (PHD) finger, which is a conserved motif of histone binding proteins. We showed that plant height and number of spikelets per panicle were increased in the OsVIL2-overexpression (OsVIL2-OX) and osvil4 plants, respectively. Each mutants (OsVIL2-OX and osvil4) exhibited longer internodes and thicker stems than wild type controls. Histochemical analysis revealed that cells are smaller in OsVIL2-OX and osvil4 plants. We performed an RNA-seq using 1st internodes of WT and OsVIL2-OX stems and got the suppressed target genes in the OsVIL2-OX. OsCKX2, which encodes cytokinin oxidase/dehydrogenase is one of the suppressed genes in the OX plants and we verified decrease of that gene using qrt-pcr and closed chromatins of OsCKX2 were enriched in the OX plants by using ChIP. As results of these, cytokinins were enriched in the OX plants. These demonstrate that OsVIL2 and OsVIL4 antagonistically regulate plant height and number of spikelets by controlling cytokinin contents. Like OsVIL2-OX and osvil4 plants, besides, OsVIL1-OX plants were also shown increased plant height and biomass. We propose that OsVILs may be used for improving grain yield by increasing biomass. *Corresponding Author: Tel. 031-201-3470, E-mail: genean@khu.ac.kr - 289 -
PD-38 Structural and Functional Insights into Enzymes in Nitrogen Remobilization Pathway Inchul Shin, Kitae Han, Sangkee Rhee * Department of Agricultural Biotechnology, Seoul National University, Seoul 151-741, Republic of Korea Nitrogen is an essential nutrient in plants including many crops. The storage and remobilization of nitrogen constitutes the main metabolic process for growth and development of plants. Ureide pathway is the lately characterized metabolic route for purine degradation and is conserved in plants, as well as some bacteria and fungi. The catabolic pathway catalyzes in a stepwise manner a conversion of N-rich uric acid into glyoxylate, with the release of ammonia, and plays a pivotal role in the storage and recovery of nitrogen from metabolites. In Next Generation BioGreen21 project, we aim to understand structural and functional features of enzymes involved in this nitrogen recycling pathway, by using genes from Arabidopsis thaliana. In this study, we report our current progress on this project including two different enzymes; ureidoglycine aminohydrolase (UGlyAH), and ureidoglycolate amidohydrolase (UAH). In UGlyAH, the metal-binding site plays a crucial role in catalysis, with a release of ammonia. We were able to characterize catalytic residues in the active site and provides a detailed view of a metal-dependent enzyme mechanism. Recently, we were able to characterize structural properties of UAH. Based on our analysis, we are performing enzymatic analysis to identify functional aspects of the enzyme. Taken together, these studies would provide a novel functional feature of the enzymes involved in the nitrogen recycling pathway and could serve as a framework to develop crops with an enhanced N-efficiency. *Corresponding Author: Tel. 02-880-4647, E-mail: srheesnu@snu.ac.kr PD-39 고추탄저병및 CMV 저항성마커개발과복합내병성품종육성과제진도보고 박석진, 도재왕, 한정헌, 윤재복 ( 주 ) 고추와육종 본과제는 고추육종가맞춤식고효율분자육종시스템실용화 과제의주관과제인, 고추탄저병및 CMV 저항성마커개발과복합내병성품종육성 ( 고추와육종, 윤재복 ) 으로, 세부과제인고추유용분자표지의 foreground selection 용 multiplexing 기술개발 ( 전북대학교, 이준대 ) 과협업을통해 2015~2017 년까지탄저병과오이모자이크바이러스 (cucumber mosaic virus, CMV) 에대한복합내병성품종개발을목표로하고있다. 탄저병과 CMV 는국내외에서심각한문제를일으키고있는병원체로, 저항성품종육성효율을높이기위해서는, 탄저병저항성연관신규분자표지와 CMV 강병원성계통 ( 기존저항성 Cmr1 극복 CMV, CMV-P1) 에대한저항성연관분자표지개발이필요하다. 본과제의성공적인수행을위해현재까지진행된연구결과는다음과같다. 탄저병저항성연관신규분자표지개발의경우, 탄저병및 CMV 복합 CMS 모계 (B) 와부계 (C) 계통, GMS 모계는각각 BC 1 F 3 와 F 4, F 5, BC 1 F 6 까지세대진전하였다. 탄저병과바이러스에단독혹은복합내병성을지닌 CMS 와 GMS 모계, 탄저병저항성 C 계통간에 156 개교배조합을작성하였고, 시교사업은경북, 경남, 충북, 충남, 전남, 전북, 강원, 인천, 제주지역을포함하는 138 개지역에수행하고있다.

The timing of germination is determined by coordinated action of two phytohormones, gibberellin (GA) and abscisic acid (ABA). In particular, ABA plays a key role in integrating environmental information and inhibiting the germination process. Utilization of embryonic lipid reserves contributes to seed germination by acting as an energy source, and ABA suppresses lipid degradation to modulate the germination process. Here, we report that the ABA-responsive R2R3-type MYB transcription factor MYB96, which is highly expressed in embryo, regulates seed germination by controlling the expression of ABA-INSENSITIVE 4 (ABI4). In the presence of ABA, germination was accelerated in MYB96-deficient myb96-1 seeds, whereas the process was significantly delayed in MYB96-overexpressing activation-tagging myb96-ox seeds. Consistently, myb96-1 seeds degraded a larger extent of lipid reserves even in the presence of ABA, while reduced lipid mobilization was observed in myb96-ox seeds. MYB96 directly regulates ABI4, which acts as a repressor of lipid breakdown, to define its spatial and temporal expression. Genetic analysis further demonstrated that ABI4 is epistatic to MYB96 in the control of seed germination. Taken together, the MYB96-ABI4 module regulates lipid mobilization specifically in the embryo to ensure proper seed germination under suboptimal conditions. *Corresponding Author: Tel. 010-8948-0992, E-mail: kyounghee@jbnu.ac.kr - 292 -

Here we report that Gle1 (GLFG lethal 1) in conjunction with InsP 6 functions as an activator of the ATPase/RNA helicase LOS4 (Low expression of osmotically responsive genes 4), which is involved in mrna export in plants, supporting the Gle1-InsP 6 -Dbp5 (LOS4 homolog) paradigm proposed in yeast. Interestingly, plant Gle1 proteins have modifications in several key residues of the InsP 6 -binding pocket, which reduce the basicity of the surface charge. Arabidopsis Gle1 variants containing mutations that increase the basic charge of the InsP 6 -binding surface show increased sensitivity to InsP 6 concentrations for the stimulation of LOS4 ATPase activity in vitro. Expression of the Gle1 variants with enhanced InsP 6 sensitivity rescues the mrna export defect of the ipk1 (inositol 1,3,4,5,6-pentakisphosphate 2-kinase) InsP 6 -deficient mutant, and furthermore, significantly improves vegetative growth, seed yield, and seed performance of the mutant. These results suggest that Gle1 is an important factor responsible for mediating InsP 6 functions in plant growth and reproduction, and that Gle1 variants with increased InsP 6 sensitivity may be useful for engineering high-yielding low-phytate crops. - 293 -
PD-44 Development of EMS mutant populations in Capsicum annuum and identification of non-pungent mutants Muhammad Irfan Siddique, Koeun Han, Doyeon Hwang, Hee-Jin Jeong, Arti Rai, Byoung-Cheorl Kang * Department of Plant Science, Plant Genomics and Breeding Institute, and Vegetable Breeding Research Center, College of Agriculture and Life Sciences, Seoul National University, Seoul 151-921, Republic of Korea Plant breeding requires genetic diversity of useful traits for crop improvement. EMS-induced mutation is practiced to generate mutations at loci regulating economically important traits and/or to knock out the genes to elucidate their functions. The present study was aimed to induce mutations in a Korean local land race Capsicum annuum Yuwol-cho. This accession is pungent and also has advantage to mature early. A total of about 1,500 M2 families were screened and three non-pungent mutants were identified and crossed with wild type Yuwol-cho. After phenotyping of F 2 population for pungency, MutMap approach will be used to identify the genes controlling the pungency in mutants. In addition to this, another C. annuum accession Micro-Pep was used to develop a mutant population. Micro-Pep is a small, pungent pepper generally used as ornamental purpose. Having compact growth habit, and small size, it has advantage to handle and utilize easily in mutation study and molecular research. On the basis of preliminary experiment 1.3% of mutagen was used for treatment of pepper seeds and 30% less germination percentage was observed in EMS treated seeds in comparison to control seeds. A total of 4,674 M 1 plants are grown under greenhouse condition and M 2 population will be studied for characterization of phenotypic variation including fruit color and pungency. Newly constructed mutant populations will be valuable assets for identification of functional genes and molecular breeding of pepper. *Corresponding Author: Tel. 82-2-880-4563, E-mail: bk54@snu.ac.kr PD-45 Development of a New Wheat Mutant of Low-Molecular-Weight Glutenin Subunit at Glu-B3 Locus Jong-Yeol Lee 1*, Hye-Rang Beom 1, Sun-Hyung Lim 1, Young-Mi Kim 1, Chul-Soo Park 2 1 National Academy of Agricultural Science, RDA, Jeonju, 560-500, Korea 2 Department of Crop Agriculture and Life Science, Chonbuk National University, Jeonju 561-756, Korea A wheat mutant of low-molecular-weight glutenin (LMW-GS) Gunji-2 at Glu-B3 locus was derived among the double haploid lines. Gunji-2 was derived from F1 plants of Keumkang and Olgeuru crosses using the wheat maize system according to the procedures of Inagaki and Mujeeb-Kazi at International Maize and Wheat Improvement Center (CIMMYT). Deletion of Glu-B3 LMW-GS proteins was found by allele specific DNA marker, one dimensional SDS-PAGE and two dimensional gel electrophoresis (2-DGE). Tandom mass spectrometry (MS/MS) was used to obtain direct evidence of LMW-GS deletion. In addition, we examined the basic agronomic traits, protein content, dough properties of mixing and bread loaf volumeof Gunji-2 and parental wheat cultivars grown for two years. This mutant will represent a valuable resource in quality test for specific allele or gene at Glu-B3 locus. *Corresponding Author: E-mail: jy0820@korea.kr - 294 -

Various P. ginseng cultivars exhibit a range of morphological and physiological traits as well as genetic diversity. To elucidate the differences of primary metabolism underlying such genetic diverstiy, we performed primary metabolite profiles in adventitious roots from five Panax ginseng cultivars using gas chromatography-mass spectrometry (GC-MS). The GC-MS analysis revealed eight primary metabolites as biomarkers and allowed us to classify the five cultivars into three groups. We selected three cultivars to represent each group and analyzed their transcriptomes by Illumina sequencing. We inspected 100 unigenes involved in seven primary metabolite biosynthesis pathways and found that 21 unigenes encoding 15 enzymes were differentially expressed among the three cultivars. Integrated analysis of transcriptomes and metabolomes revealed that the ginseng cultivars differ in primary metabolites as well as in the putative genes involved in the complex process of primary metabolic pathways. Our data derived from this integrated analysis provide insights into the underlying complexity of genes and metabolites that co-regulate flux through these pathways in ginseng. *Corresponding Author: Sung Won Kwon, E-mail: swkwon@snu.ac.kr, Tae-Jin Yang, E-mail: tjyang@snu.ac.kr - 295 -

PD-49 Development of molecular markers tightly linked to bacterial wilt resistance genes in pepper (Capsicum annuum L.) Daewoong Lee 1, Yul-Kyun Ahn 2, Younghoon Park 3, Tae-Hwan Jun 1* 1 Department of Plant Bioscience, Pusan National University, Miryang, Republic of Korea 2 Vegetable Research Division, National Institute of Horticultural & Herbal Science, Rural Development Administration, Wanju-gun, Republic of Korea 3 Department of Horticultural Bioscience, Pusan National University, Miryang, Republic of Korea Bacterial wilt (BW) caused by Ralstonia solanacearum is one of the most common soil-borne vascular diseases of many solanaceous crops such as pepper and tomato. This study aimed to develop molecular markers closely linked to bacterial wilt resistance genes using a 150 F 8 recombinant inbred line (RIL) population obtained from a cross of YCM334 x Taean. For pathogen inoculations, R. solanacearum isolate WR-1 was cultured on NB medium at 28 for 48 h and a bacterial suspension was adjusted to 1 x 10 7 to 1 X 10 8 CFU/mL (A 600 = 0.3 to 0.4). Each RIL and the parents were sown in a 72-cell plastic tray filled with sterilized soil, and the seedlings were inoculated at the 6 to 8 leaf stage using soil-drenching (3 to 5 ml/ plant) inoculation methods with 3 replications. After 10 days post inoculation (dpi), each line was evaluated visually for occurrence of bacterial wilt ranging from 1 (most resistant) to 5 (most susceptible). Two candidate R-response genes, AT4G14130 and AT3G23730, were selected to find SNPs between YCM334 and Taean. In previous transcriptome analysis, these two genes were reported as significantly differentially expressed in Capsicum annuum L. root inoculated with R. solanacearum, which were up-regulated in a resistant genotype. Once the synteny of the gene locations between Arabidopsis and pepper was documented, the sequences on pepper chromosome 12 were obtained from pepper. v.1.55 (http://solgenomics.net). SNP markers associated with resistance to BW will be mapped using pepper RIL population. *Corresponding Author: Tel. 055-350-5507, E-mail: thjun76@pusan.ac.kr - 298 -

PD-51 Drought stress-responsive transcript analysis of wheat-rye translocation line using cdna-aflp Woo Joo Jung, Yong Weon Seo * Dept. of Biosystems & Biotechnology, Korea University, Seoul 136-713, KOREA Wheat-rye translocation lines are widely used in wheat breeding programmes by reason of biotic stress tolerances. Though there have been a number of researches regarding abiotic stress tolerance, the tolerance of the lines depends on wheat genetic background, not on rye chromosome. Here, we investigated wheat-rye translocation specific transcripts derived from cdna-aflp under drought stress, which may help to elucidate the reaction under the stress. OK91G117 (1BL.1RS translocation) and OK91G144 (non-translocation) were used as materials, which are near-isolines for 1RS. 25% PEG 6000 was added in culture solution to simulate drought condition and root tissues were sampled at each 0 h, 3 h, 6 h, 12 h, 24 h, and 48 h after PEG treatment for RNA extraction. As a result of cdna-aflp, TDFs (transcript derived fragments) that were specific to OK91G117 were sequenced. GO functions of each sequenced TDF were annotated by Blast2GO using standard parameter with cut-off level 3 and mapped to the GO term (i.e. biological process; BP, molecular function; MF, cellular component; CC). The term with organic substance metabolic process, primary metabolic process, and cellular metabolic process account for almost 50 % of BP. The most represented terms among probes classified to MF were transferase activity and most of TDF were annotated in cell part of CC. In addition, rye-chromatin specific markers were developed by BLAST comparing sequence of TDF with wheat and rye genome data. RT-PCR was conducted to validate expression patterns of selected TDF. Further studies will be needed to elucidate functions of the highly expressed genes under drought stress.

Custom-designed ZFNs can induce double-strand breaks (DSBs) at a specific locus. Our custom ZFN dimer was designed 3-finger of left and 4-finger of right with 2 kb size using 2A. A Ti-plasmid vector, pta7002 containing the target site of SSS4A gene for a ZFN pair, that was shown to be active in yeast, was integrated in the rice genome. This promising technique for genome engineering was induced into 4 exon region of SSS4A gene in rice genome using Agrobacterium-mediated transformation. The SSS4A full-length cdna was 5,070 bp consisting of a 318 bp 5 -untranslated region (UTR), a complete ORF of 2,928 bp encoding a polypeptide of 975 amino acids and a 3 -UTR of 1,824 bp. The vector is based on glucocorticoid receptor inducible gene expression system. Thus, SSS4A::ZFN expression was tightly controlled and the phenotype in low concentrations 10uM of the glucocorticoid hormone dexamethasone (DEX). In plant cells, transient ZFN expression is achieved by direct gene transfer into the target cells. For an alternative, ZFN delivery and production of mutant plants using a tobacco transient expression system for indirect transient delivery of ZFNs into a variety of tissues and cells of plants. ZFN activity was determined by PCR and sequence analysis of the target site. ZFN induced plants were obtained in up to 2% of the PCR products, consisting of deletions ranging between 1and 100 bp and insertions ranging between 1 and 10 bp. Our results describe an alternative to direct gene transfer for ZFN delivery and for the production of mutated rice. - 301 -

Gayabyeo, a Tongil type rice variety, is known to have broad spectrum resistance to BPH. Before, it was estimated that Gayabyeo has at least two BPH resistance genes. We started a research for mapping resistance genes of Gayabyeo. We did a cross between Taebaekbyeo, a BPH susceptible Tongil type rice variety, and Gayabyeo, We grew F1 plants in winter season of 2014-2015, and planted F2 population in this year. About 100 DNA markers (SSR and InDel markers) showing polymorphism between Gayabyeo and Tabaekbyeo were selected. In addition, we are going to do resequencing Gayabyeo and Taebaekbyeo using Illumina Hiseq2000 to find much more DNA polymorphisms between the two varieties and develop new markers for mapping. The BPH response data will be acquired using F3 plants from the cross between Gayabyeo and Taebaekbyeo next year. In a while, crosses between Gayabyeo and high quality japonica rice varieties are being carried out to introduce BPH resistance genes of Gayabyeo into japonica high quality rice varieties. We expect to develop new DNA markers for BPH resistance genes of Gayabyeo through mapping and produce several japonica high quality rice lines harboring those genes at the end of this project. *Corresponding Author: Tel. 031-299-1697, E-mail: jhs77@korea.kr PD-54 Identification of quantitative trait loci for fusarium wilt resistance in radish (Raphanus sativus) Juyeon Jung, Jaehwang Ryu, Yeonok Choi, Young-Pyo Lee * Dongbu Farm Hannong Co., Ltd, Anseong-si, Gyeonggi-do, 456-933, Republic of Korea Radish, Raphanus sativus(2n = 18), belonging to the brassicaceae family, is herbaceous plant with 1-2 years life cycle. It is cultivated worldwide for producing leafy and root vegetables. Although an economically important crop, the genetics of yield and quality traits, disease resistance are not well-studies. The major purpose of this project is development of molecular breeding technology in radish. In this project, quantitative trait loci (QTL) for Fusarium wilt resistance of radish were analyzed. To identify QTL, genetic linkage map of radish was constructed using F2 mapping population derived from a cross between two inbred lines, DB01 (resistant) and DB05 (susceptible). A total 319 markers have been mapped into nine linkage groups, covering 639.3cM with an average distance of 2cM between loci. QTL mapping detected 2 loci conferring Fusarium wilt resistance. Two QTLs were located on LG3 and LG7, respectively. The QTL of LG3, flanked by EAGGMCT6 and WALK500 marker, exhibited a LOD value ranging from 2.3 to 8.7, and the R2 (Phenotypic variations) ranging from 28 to 48% in four tests. This QTL was named qyr1. The QTL of LG7, flanked by EACCMCAC-202 and DCJ14-390 marker, exhibited a LOD value ranging from 6.2 to 10.6, and the R2 ranging from 42 to 55% in four tests. This QTL was named qyr2. The results of the QTL analysis may be useful in marker-assisted selection (MAS) of Fusarium wilt resistant radish cultivars. *Corresponding Author: Tel. 031-674-6911, E-mail: youngpyo@dongbu.com - 302 -

BRs act alone or with other exogenous and endogenous signals including auxin and light. To screen for the novel player involved in BR signaling in Arabidopsis, we employed cdna overexpression strategy. We created a cdna library to be expressed under the 35S overexpression promoter, and introduced into a weak brassinosteroid insensitive 1 (bri1) mutant. The mutant dubbed bri1-5 with long petiole (blp) was identified to display bigger stature especially in hypocotyl and petiole length relative to bri1-5. Sequence analysis of the rescued transgene revealed that blp consisted of a chimeric DNA consisting of a 3 half of PHYB, 2 bp insertion, and a part of a chloroplast ribosomal RNA. Re-introduction of chimeric DNA into bri1-5 recapitulated blp phenotype. The blp phenotypes being similar to phyb mutants led us to examine both the PHYB transcript and protein levels in the blp 35Spro:PHYB doubly homozygous line. Lower levels of both transcripts and proteins of PHYB suggested that introduction of the chimeric gene interfered with the stability of PHYB transcripts. Our results highlight that overexpression mutagenesis facilitates functional genomics to decipher a function of Arabidopsis genome.

PD-56 Quantitative trait locus mapping and candidate gene analysis for heading date in an early maturing rice mutant induced by gamma irradiation Sun-Goo Hwang, Cheol-Seong Jang * Plant Genomics Lab, Department of Applied Plant Sciences, Kangwon National University, Chuncheon 200-713, Republic of Korea In recent years, the efficiency and accuracy of QTL analysis for identification of useful traits have been increased by high-throughput genotyping. In a previous study, the genome variation of significant DNA polymorphism was observed in early maturing type rice mutant (EMT) by comparing with that of wild type (WT). For detection of major QTL for flowering time, we constructed a linkage map of 36 InDel- and 6 SNP- markers. In the linkage analysis of F 2 plants derived from the cross WT x EMT, we have detected one potential QTL region on chromosome 6 by M6-3 marker. Also, the Hd1, which contained the target fragment of M6-3 marker, exhibited the relatively high nonsynonymous substitutions in genes located on chromosomal region from M6-2 to M6-4. To evaluate the reliable allele segregation related to expected Mendelian ratio between M6-3 and its flanking markers, M6-3 marker developed in Hd1 gene exhibited the 1:2:1 ratio as clear monogenic segregation in heterozygous F 3 plant. Additionally, we further analyzed the different transcript regulations of OsGI and Hd3a gene related to Hd1 involved in photoperiodic flowering pathway. Although the mrna levels of Hd1 had no difference between WT and EMT, the Hd3a as downstream effector of Hd1 significantly upregulated in EMT, suggesting that Hd1 gene may become nonfunctional. *Corresponding Author: Tel. 033-250-6416, E-mail: csjang@kangwon.ac.kr PD-57 초형개량초다수성콩분자육종 Molecular breeding for high-yielding soybean with improved plant type 이석하 1, 정지원 2 1 서울대학교 2 씨제이제일제당 본연구과제의목적은 1) 양질다수성콩기술이전, 2) 양질다수성콩품종출원, 3) 고밀도유전자지도작성을통한다수성관련 QTL 동정및다수성형질연관마커개발, 4) 콩품종판별마커개발, 5) 기능성콩가공식품개발이다. 이를위해당해연도는양질다수성콩품종육성을위한생산력검정및지역적응성검정을실시하고초다수성우량계통육성을위해 1 단계사업에서선발된우량계통들을지속적으로세대진전하고자한다. 특히다수성관련형질연관 QTL 동정을위해길육 69 x SS0404-T5-76 RIL 집단 (400 계통 ) 을육성하였고이집단을이용한고밀도유전자지도작성하고자한다. 먼저모부본염기서열변이탐색및 RIL 들의다수성형질표현형을조사할것이다. 한편, 품종보호및종자순도관리에있어서중요한분자마커개발을위해주요품종들에대한 SSR 마커분석을실시하였다. 당해연도에는 1 단계사업에서개발된 CJ 행복한 1 호 콩품종육성을위한채종포를제주도와괴산등지에조성하며두부장류용우량계통 SS408-T5-99 에대한제품생산가능성분석하고장류발효과정중아이소플라본의성분변화를분석할것이다. - 304 -

OG-02 Multiple Recognition of RXLR Effectors is Associated with Nonhost Resistance of Pepper Against Phytophthora infestans Doil Choi Department of Plant Science, College of Agriculture and Life Sciences, Seoul National University, Seoul 151-921, Republic of Korea Nonhost resistance is a plant immune response to resist most pathogens. The molecular basis of nonhost resistance remains poorly understood but recognition of pathogen effectors by immune receptors, a response known as effector-triggered immunity, has been proposed as a component of nonhost resistance. We performed transient expression of 54 P. infestans RXLR effectors in pepper accessions using optimized heterologous expression methods and analyzed the inheritance of effector-induced cell death in an F2 population derived from a cross between two pepper accessions. Pepper showed a localized cell death response upon inoculation with P. infestans, suggesting that recognition of effectors may contribute to nonhost resistance in this system. Nonhost pepper accessions recognized from 2 to 36 effectors. Among the effectors, PexRD8 and Avrblb2 induced cell death on a broad range of pepper accessions. Segregation of effector-induced cell death in an F2 population derived from a cross between two pepper accessions fit a 15:1, 9:7 and 3:1 depending on the effector. Our genetic data suggests that single or two independent/complementary dominant genes are involved in the recognitions RXLR effectors. Our findings indicate that multiple loci recognizing a series of effectors underpin nonhost resistance of pepper to P. infestans and may confer resistance durability. - 312 -

OH-01 Gene-specific marker development of cabbage for an efficient molecular breeding Yoonkang Hur 1, Yong-Pyo Lim 1, Ill-Sup Nou 2 1 Chungnam National University, Daejeon, Korea 2 Sunchon National University, Jeonnam, Korea Molecular markers, such as PCR-based and SNP-based markers, are extremely useful for plant genetics and crop breeding. Marker-assisted selection (MAS) has been widely applied in plant breeding to improve crop yield, quality, and tolerance to biotic and abiotic stresses. To develop gene-based (or -specific) molecular markers, three different approaches have been used in Brassica species: Known-gene-based, RNA seq/exon-based and RNA seq/intron-based molecular marker development for several years. Using these techniques, molecular markers have been developed to identify flowering time, anthocyanin accumuation and abiotic stresses in B. rapa and B. oleracea. Markers were distributed in exons as well as introns, and coding sequences and untranslated regions (UTRs). All markers developed have been transformed into SNP marker after HRM confirmation. I will discuss efficiency, accuracy, and potential problems and contribution of these markers for Brassica breeding. [This research was supported by Golden Seed Project (Center for Horticultural Seed Development, No. 213003-04-2-SB230), Ministry of Agriculture, Food and Rural Affairs (MAFRA), Ministry of Oceans and Fisheries (MOF), Rural Development Administration (RDA), and Korea Forest Service (KFS).] - 315 -
OH-02 Molecular breeding stratagies for pyramiding viral resistances in tomatoes Inhwa Yeam Department of Horticulture and Breeding, Andong National University, Andongsi, Gyeongsangbukdo, 760-749, Republic of Korea Marker assisted selection (MAS) for disease resistance is widely applied in practical tomato breeding program both in public and private sectors. Due to the commercial value and the importance as a model crop system, tomato has taken the lead in MAS among the other horticultural crops. A wide range of disease resistance genes were identified and the mechanism of the resistances has been explored in tomatoes. In the case of disease resistance Tomato yellow leaf curl virus (TYLCV) is one of the major threats for tomato production worldwide, and several resistance sources for TYLCV resistance have been identified among wild tomato species. Ty1/3 resistance gene has been recently identified as a DFDGD-class RNA dependent RNA polymerase (RDR). Late blight (LB) in tomato is caused by Phythophthora infestans, and several resistances sources have been applied in the practical breeding program. Ph3 resistance, a LB resistance against a wide-range of P. infestans isolates, has been reported as a gene coding a CC-NBS-LRR gene on chromosome 9. In this study, we developed reliable and comprehensive molecular markers based on the single nucleotide polymorphisms (SNPs) or insertion/deletion (InDel) directly responsible for the resistance phenotype. These functional molecular markers are expected to enhance the effectivity and accuracy of MAS for disease resistance in tomato breeding programs. - 316 -
OH-03 High-density genetic map construction and QTL analysis for seed size of fruits and powdery mildew resistance in watermelon Gung Pyo Lee Dept. of Integrative Plant Science, Chung-Ang University, 456-756, Republic of Korea Recently, many breeders have preferred to use molecular markers for introgression backcross programs enabling foreground and background selection to cope with rapid cultivar changing of seed markets. In accumulation of target traits with marker-assisted selection, larger numbers of markers should give better resolution. For the analysis of quantitative traits, a high-density genetic map with a large number of markers is required for discovering more accurately linked markers with traits. Watermelon is a recalcitrant plant to generate a high-density genetic map with conventional molecular markers including simple sequence repeats (SSRs), since watermelon has narrow genetic diversity background and severe segregation distortions of those SSR markers. Thus, we have developed efficient and valid way to assemble genetic map and markers by next-generation sequencing coupled with genotyping by sequencing in F2 generation. After crosses between Citurullus lanatus ssp. citroides (PI254744 and PI189225) and C. lanatus ssp. lanatus (TS34, Korean cultigen), 163 of F2 progeny were sequenced through Illumina's Hi-Seq GAII platform. From sequence information of those variant call files, the SNPs were indexed and filtered by sequencing depth with genotype converter (SNP Genotyper), and optimized by heuristic physical bin mapping to construct more reliable genetic linkage map. Reliable SNP loci were determined and compared to sequences of physical reference map. Using the genetic map, we determined QTLs in F2:3 population and found major loci corresponding to seed size and powdery mildew race1 resistance in watermelon. - 317 -
OH-04 Genomics approach to develop molecular markers for targeted breeding of radish Ji-Young Lee, Kook Hui Ryu, Jung-Hun Lee, Khushboo Rastogi, Goh Choi School of Biological Sciences, Seoul National University, Seoul Korea Radish is one of the most widely consumed vegetable crops in Korea. Root is the major part of radish supplied to the market, thus the size, shape, and quality of radish roots are main targets of breeding programs. Despite of the importance of this crop, the molecular breeding of radish is still in the rudimentary stage. In Golden Seed Project, we aim to establish the molecular breeding program of radish using genome-wide approaches. To this end, we selected inbred lines that have distinctive root traits such as yield, shape, disease resistance, and texture. Single nucleotide variation (SNV) among these lines will be identified based on the low coverage genome sequencing data. These SNVs can be used for finding genomic regions associated with root traits from segregating mapping populations which are also in the middle of development. Korean radish roots are harvested after being grown for only nine weeks. During that period, root biomass reaches to more than two kilograms. While investigating the root growth of radish inbred lines, we found that cytokinin contributes as a key growth regulator that promotes radial growth of radish roots. A difference in growth rates of two distinctive inbred lines was explained by the difference in response to cytokinin. Genes responsive to cytokinin are highly enriched in the cambium, the meristematic cell population that drives radial growth. For comprehensive understanding of genes that affect yields of radish roots, we turned to developing a tissue specific transcriptome data using laser capture microdissection. We expect that the compendium of genomics-based data will help establishing molecular breeding of radish at a fast track. - 318 -
