  • Here we report the draft genome sequence of Weissella koreensis strain HJ and genomic analysis of its key features. The genome consists of 1,427,571 bp with a GC content of 35.5%, and comprises 1,376 coding genes. In silico analysis revealed the absence of pathogenic factors within the genome. The genome harbors several genes that play an important role in the survival of the gastrointestinal tract. In addition, a type III polyketide synthase cluster was identified. Pangenome analysis identified 68 unique genes in W. koreensis strain HJ. The genome information of this strain provides the basis for understanding its probiotic properties.

  • Brassica rapa is considered an ideal candidate to act as a reference species for Brassica genomic studies. Among the three basic Brassica species, B. rapa (AA genome) has the smallest genome (529 Mbp), compared to B. nigra (BB genome, 632 Mbp) and B. oleracea (CC genome, 696 Mbp). There is also a large collection of available cultivars of B. rapa, as well as a broad array of B. rapa genomic resources available. Under international consensus, various genomic studies on B. rapa have been conducted, including the construction of a physical map based on 22.5X genome coverage, end sequencing of 146,000 BACs, sequencing of >150,000 expressed sequence tags, and successful phase 2 shotgun sequencing of 589 euchromatic region-tiling BACs based on comparative positioning with the Arabidopsis genome. These sequenced BACs mapped onto the B. rapa genome provide beginning points for genome sequencing of each chromosome. Applying this strategy, all of the 10 chromosomes of B. rapa have been assigned to the sequencing centers in seven countries, Korea, UK, China, India, Canada, Australia, and Japan. The two longest chromosomes, A3 and A9, have been sequenced except for several gaps, by NAAS in Korea. Meanwhile a China group, including IVF and BGI, performed whole genome sequencing with Illumina system. These Sanger and NGS sequence data will be integrated to assemble a draft sequence of B. rapa. The imminent B. rapa genome sequence offers novel insights into the organization and evolution of the Brassica genome. In parallel, the transfer of knowledge from B. rapa to other Brassica crops would be expected.

  • Here, we report the draft genome sequence of Latilactobacillus sakei subsp. sakei FBL10 isolated from Saeujeot (salted fermented shrimp). The draft genome consists of 2,285,672 bp with a G+C content of 41.1% and contains 2,282 coding genes. Genome analysis revealed that clusters associated with bacteriocin production were identified, in addition to several probiotic properties, such as stress resistance factors and aggregation. On the other hand, antibiotic resistance genes and virulence factors were not present. Pangenome analysis for 32 genomes showed 213 unique genes for FBL10 strain. These results demonstrate the beneficial properties of strain FBL10 as a putative probiotic.

  • The monokaryotic strain, Schizophyllum commune strain IUM1114-SS01, was generated from a basidiospore of dikaryotic parental strain IUM1114. It even showed the decolorizing activities for several textile dyes much better than its parental strain. Based on the results of a single-molecule real-time sequencing technology, we present the draft genome of S. commune IUM1114-SS01, comprising 41.1 Mb with GC contents of the genome were 57.44%. Among 13,380 protein-coding genes, 534 genes are carbon hydrate-active enzyme coding genes.

  • Microcystis aeruginosa is a cyanobacterium that can form harmful algal blooms (HABs) producing toxic secondary metabolites. We provide here draft genome information of four strains of this freshwater cyanobacterium that was obtained by the Next Generation Sequencing approach to provide a better understanding of molecular mechanisms at the physiological and ecological levels. After gene assembly, genes of each strain were identified and annotated, and a genome database and G-browser of M. aeruginosa were subsequently constructed. Such genome information resources will enable us to obtain useful information for molecular ecological studies with a better understanding of modulating mechanisms of environmental factors associated with blooming.

  • Aeromonas spp., are Gram-negative rods that can cause infections in healthy and immunocompromised hosts. The clinical presentation of gastroenteritis varies from mild diarrhoea to shigella-like dysentery to severe cholera-like watery diarrhoea. Here, we report a case of acute hemorrhagic gastroenteritis in a newborn infant by Aeromonas caviae and its draft genome sequence. It is important to reduce the chance of incorrect isolate identification, which could lead to the exclusion of pathogenic Aeromonas spp., from routine laboratory identification in cases of diarrheal diseases. The genome sequence of A. caviae SVJ23 represents a significant step forward in understanding the diversity and pathogenesis, virulence, and antimicrobial resistance profile.
