It’s a time we prepare for a reparation agenda for Jeju 4.3 victims and their families. We should approach the USA government side collectively rather than individually for their lawsuits, because most of them are elderly, over 75 years old and need intensive medical care and assistance immediately. It’s up for us to recognize some tasks of actualizing Reparation, Reconciliation and Reconnection Agenda for “Environmentally Sustainable Peace Island” beyond Trauma of the Jeju 4.3 Grand Tragedy into the next Decade.

Islanders have tried to find out real alternatives on how to keep sustainable Haenyeo communities through both developing traditional school system at community level (Hansupul Haenyeos School) and advanced school system at university level ( an educational certificate program for Interpreter of Haenyeos Culture and an advanced certificate program for Hanyeos Culture). In oder to share their wisdom of ordinary democratic life style around Bultuk, We created Global Peace Bultuk Assembly for younger generation to succeed in their tradition in July of 2010. It' s a time for us to find out Integrating Policy of the Sustainability of Jeju Haenyeo (Jamnyeo, Jamsu) Community facing their extinction into Jeju Village Conservation Model of Marine Resources Needed.

Chinese cabbage (Brassica rapa ssp. pekinensis) is one of the most important vegetables and widely cultivated in Asia countries including Korea and China. Recently, whole genome sequence and full-length cDNA information of this species became available, which are encouraging genetic studies of this species to characterize agricultural important traits. Orange-colored (Or) cultivar of Chinese cabbage has inner leaves in orange, whereas other cultivars generally cultivated have yellow (Ye)- or white-colored inner leaves. In this study, we investigated phenotypes and carotenoid biosynthesis genes related to color variation in the Or cultivar. Firstly we compared the carotenoid content and composition between the Or and Ye cultivars by HPLC analysis. The inner leaves of Or cultivar contained approximately 9-fold high β-carotene content, whereas content of both lutein and violaxanthin was decreased to less than 30%, compared to Ye cultivar. Or cultivar was segregated with ratio of 3:1 in F2 population derived from crossing between Or and Ye inbred lines, indicating that Or phenotype is controlled by single recessive gene. To identify this gene, we investigated the expression of several genes involved in carotenoid biosynthesis by RT-PCR analysis. Among genes tested, two encoding putative carotenoid isomerase (CRTISO) and phytoene desaturase (PDS) were identified to show different expression between Or and Ye cultivars. Through further analysis of genomic DNA regions of these two genes, we could expect that several mutations such as InDel and base-substitution occurred and then affected expression of these genes in Or cultivar. In this presentation, I will introduce more detailed results for Or cultivars.

family in the Brassica genome sequences by computational approach. The MITE family showed a total of 264bp length including 36bp terminal inverted repeats and remained 2bp (TA) targets it eduplication by its insertion. By searching the genome database of Brassica species, 516, 227, and 15 members were identified from 470Mbp of Brassica oleraceae, 154Mbp of B.rapa and 15Mbp of B.napus, respectively, indicating that there are approximately 692, 760, 1235 copies in B.oleracea, B.rapa and B.napus genomes,respectively. A total of 225 relatively intact MITE members, 146,68, and 11 members, which showed >80% sequence similarity and sequence coverage were identified and retrieved for MITE analysis from B.oleracea, B.rapa and B.napus genomes, respectively. Out of 225 MITE family members 159 having full structure of MITE and 66 having the truncated end either in right TIR or left TIR. Insertion polymorphism due to insertion or non-insertion of MITEs showed high level of polymorphism among accessions intra and inter species of Brassica. The new MITE would provide abetter tool for study molecular breeding in Brassica species and also helpful to understand their contribution in evolution and diversification of the highly duplicated Brassica genome.

Perilla is a genus as a member of the mint family Lamiaceae which is known to contain lots of volatile metabolite. Perilla has been called as ‘deulkae’ indicating ‘wild sesame’ that means it has been maintained in Korea with long history. It has been very friendly used as edible oil and as fresh leaf vegetable. Perilla oil is valued for its medicinal benefit because it contains best amounts of unsaturated fatty acids, especially for the alpha-linolenic acid, known to omega-3 fatty acid, among all of the plant oils. It also include many beneficial phytochemicals. However, little study is conducted on their genetics. Here, we announce construction of well normalized and full length enriched-perilla cDNA library from a whole plant of one cultivar ‘Youngho-deulkae’ and their sequence characterization to provide useful resources for genetics, breeding and metabolite engineering. By sequencing of 5,760 cDNA clones, we 5,438 high quality EST sequences. Sequence trimming and assembly resulted 3,995 unigenes which consists 1,004 contigs and 2,991 singletones. Unigenes that showed little homology at the DNA sequence level with known genes in other plants even though they showed similarity at the protein domain level based on BLASTN, BLASTX, and TBLASTX. This study may provide good resources for initiation of further genomics, comparative genomics, functional genomics such as metabolic engineering and molecular breeding.
