Flavobacteriaceae 과에 속하는 신균주인 RR4-38(= KCTC 52651 = DSM 108068)가 한국의 해수 순환여과양식시스템의 생물여과조에서 분리되었다. 41.9%의 G+C 함유량을 가진 3,182,272 bp의 길이의 하나의 완전한 유전체 컨티그가 PacBio RS II를 이용하여 얻어졌다. 이 유전체는 2,829개의 단백질 암호화 유전자와 6개의 rRNA 유전자, 38개 tRNA 유전자, 4개의 ncRNA 유전자, 9개의 유사유전자를 포함하고 있다. 이 결과는 해수 순환여과양식시스템에서 미생물의 활성을 이해하는데 통찰력을 줄 것이다.

Escherichia coli normally colonizes the lower intestine of animals and humans, but some serotypes are foodborne pathogens. The Escherichia coli K_EC180 was isolated from swine feces that were collected from a weaner pig. In this genome announcement, E. coli K_EC180 was sequenced using PacBio RS II and Illumina NextSeq 500 platforms. The complete chromosome of E. coli K_EC180 is composed of one circular chromosome (5,017,281 bp) with 50.4% of guanine + cytosine (G + C) content, 4,935 of coding sequence (CDS), 88 of tRNA, and 22 of rRNA genes. The complete genome of E. coli K_EC180 contains the toxin genes such as shiga-like toxins (stxA and stxB).

Lindera angustifolia is mainly distributed in the temperate climate zone of China but shows an extraordinary distribution, disjunctively isolated on the western coastal islands of Korea. We therefore present the complete chloroplast genome of Korean L. angustifolia. The complete plastome was 152,836 bp in length, with an overall GC content of 39.2%. A large single copy (93,726 bp) and a small single copy (18,946 bp) of the genome were separated by a pair of inverted repeats (20,082 bp). The genome consists of 125 genes, including 81 protein-coding, eight ribosomal RNA, and 36 transfer RNA genes. While five RNA editing genes (psbL, rpl2, ndhB×2, and ndhD) were identified in L. angustifolia from China, the "ndhD" gene was not recognized as an RNA editing site in the corresponding Korean individual. A phylogenetic analysis revealed that Korean L. angustifolia is most closely related to the Chinese L. angustifolia with strong bootstrap support, forming a sister group of L. glauca.

The full genome sequence of a Korean white spot syndrome virus (WSSV, isolate: WSSV-GoC18) is presented here. We obtained a total of 12,320,554 reads with 291,172 bases, 170 gene, and 170 coding DNA sequence, which were assembled in 1 contig. Phylogenetic analysis revealed that the WSSV-GoC18 was closely related to Chinese isolate (WSSV-PC) and distinctly different with previously reported a Korean isolate (WSSV K-LV1). The complete genome sequence of WSSV isolates will be of great help in molecular epidemiological studies, contributing to molecular diagnosis and disease prevention in shrimp aquaculture.

Here we report the complete genome sequence of Bacillus amyloliquefaciens ATC6, which produces acidic cellulase, isolated from pig feces. The genome is 4,062,817 bp in length and has a guanine-cytosine (GC) content of 46.27%. Among the predicted 3,913 protein-coding genes, two glucanase genes, which are involved in lichenan and cellulose degradation, were found. This genome analysis helps clarify the mechanism involved in cellulose biodegradation and support its application for efficient use of livestock feeds.

Arabidopsis thaliana (L.) Heynh. is a small plant species that serves as a model organism of plant biology and genetics. Here, we present the first complete mitochondrial genome of Korean A. thaliana natural isolate (named as 180404IB4), which is 368,875 bp long and contains 58 genes (33 protein-coding genes, 22 tRNAs, and three rRNAs), with a GC ratio of 44.8%. Sixty-four single-nucleotide polymorphisms and 11 insertion and deletion regions (1,089 bp in length) are identified against the Col-0 ecotype, showing one large insertion of 1,069 bp without structural variation. Phylogenetic trees constructed from 30 conserved genes indicate that the 180404IB4 mitochondrial genome is clustered with Col-0 and three East Asian ecotypes.

Hibiscus sabdariffa L., (roselle) in the Malvaceae family is an erect subshrub known to be native to India and Malaysia. It is widely used as a food or tea material around the world, and its therapeutic effects have been widely studied. In this study, the sequencing of the complete chloroplast genome of H. sabdariffa was carried out. The result indicates a genome size of 162,428 bp, which is composed of a large single copy of 90,327 bp, two inverted repeats of 26,242 bp each, and a small single copy of 19,617 bp. Overall, a total of 131 genes were predicted, including 86 coding sequences, 37 tRNAs, and 8 rRNAs. According to a phylogenic analysis, it was clearly distinguished from outgroups such as other species of the genus Hibiscus used in the analysis.

The increase in canine skin and soft tissue infections, such as pyoderma and otitis, caused by Staphylococcus schleiferi strains, is of significant zoonotic concern. In this study, we report the first complete genome sequence for a methicillin-resistant clinical isolate of S. schleiferi (MRSS) designated as SS4, obtained from a dog with otitis externa, in Korea. The genome of SS4 strain was of 2,539,409 bp and presented high G+C content ratio (35.90%) with no plasmid. Comparative analysis of SS4 genome revealed that it is closely related to 2142-05 and 5909-02 strains isolated from the canine skin infections in the USA.

In this study, we report the complete genome sequence of Priestia megaterium strain HyangYak-01, which was isolated from the rhizosphere soil of Centella asiatica. The genome consists of 5,086,279 bp of sequences with 38.2 percent GC content and 5,111 coding genes. The genome contains several important genes related to plant growth-promoting activities, which were also confirmed with in vitro media assays.
