  • Geographical distribution of diploid plant with AA genome (2n=16) and allotetraploid with AABB genome (2n=34) of Scilla scilloides Complex from Korea has been studied. The composition and frequencies of B chromosomes ere also investigated. Plants with AABB genome were predominant over AA genome plants. A mixed population of AA and AABB genome plants was found for the first time. Aneuploid plants have not been found. Chromosomes of AA genome were composed of three pairs of metacentric, two pairs of submetacentric, two pairs of subtlocentric and one pair of telocentric chromosomes, whereas BB genome was four pairs of metacentric and five pairs of subtelocentric chromosomes. B chromosomes were classified into two categories, isochromosome (F) and chromosome fragment (f). The frequencies of B chromosomes were 43% in AA genome plants and 44% in AABB genome plants. The number of B chromosome ranged from 1 to 3 and 1 to 7 in AA and AABB genome plants, respectively. B chromosome combinations were F and F+f in AA genome plants and F, F+f and f in AABB genome plants.

  • Weissella koreensis DMW12 was isolated from kimchi added Myeongtae (Theragra chalcogramma), and its complete genome sequence was determined. The complete genome of strain DMW12 includes a single circular 1,518,288-bp chromosome without plasmids. The G+C content of the genome is 35.6 mol%. Although strain DMW12 did not showed protease and lipase activities, the genome includes 33 protease- and 3 lipase-encoding genes. The genome of strain DMW12 does not include acquired antibiotic resistance genes against ampicillin, chloramphenicol, clindamycin, erythromycin, gentamicin, kanamycin, tetracycline, and streptomycin.

  • We sequenced 1,841 BAC clones by terminal sequencing, and 1,830 of these clones were characterized with regard to their human chromosomal location and gene content using Korean BAC library constructed at the Korean Science (KCGS). Sequence analyses of the 1,830 BAC clones was performed for chromosomal assignment: 1,144 clones were assigned to a single chromosome, 190 clones apparently assigned to more than one chromosome, and 496 clones to no chromosome. Evaluating gene content of the 1,144 BAC clones, we found that 706 clones represented 1,069 genes of which 415 genes existed in the BAC clones covering the full sequence of the gene, 180 genes covering a $50%{\sim}99%$, and 474 genes covering less than 50% of the gene coverage. The estimated covering size of the KBAC clones was 73,379 kilobases (kb), in total corresponding to 2.3% of haploid human genome sequence. The identified BAC clones will be a public genomic resource for mapped clones for diagnostic and functional studies by Korean scientists and investigators worldwide.

  • The International HapMap Project and the Human Genome Diversity Project (HGDP) provide plentiful resources on human genome information to the public. However, this kind of information is limited because of the small sample size in both databases. A Genome-Wide Association Study has been conducted with 8,842 Korean subjects as a part of the Korea Association Resource (KARE) project. In an effort to build a publicly available browsing system for genome data resulted from large scale KARE GWAS, we developed the KARE browser. This browser provides users with a large amount of single nucleotide polymorphisms (SNPs) information comprising 1.5 million SNPs from population-based cohorts of 8,842 samples. KAREBrowser was based on the generic genome browser (GBrowse), a web-based application tool developed for users to navigate and visualize the genomic features and annotations in an interactive manner. All SNP information and related functions are available at the web site http://ksnp.cdc. go.kr/karebrowser/.
