Abstract Biocontrol offers a promising alternative to synthetic fungicides for the control of variety pre- and post-harvest diseases crops. Black rot, which is caused by pathogenic fungus Ceratocytis fimbriata , most destructive disease sweet potato, but little currently known about potential biocontrol agents this fungus. Here, we isolated several microorganisms from tuberous roots shoots field-grown potato plants, analyzed their ribosomal RNA gene sequences. The belonging genus Pantoea...
Abstract Taxonomic and functional research of microorganisms has increasingly relied upon genome-based data methods. As the depository Global Catalogue Microorganisms (GCM) 10K prokaryotic type strain sequencing project, Type Strain (gcType) published 1049 genomes sequenced by GCM project which are preserved in global culture collections with a valid status. Additionally, information provided through gcType includes >12 000 publicly available genome sequences from GenBank incorporated...

Bacterial cancer therapies aim to manipulate bacteria effectively deploy therapeutic payloads tumors. Attenuated alone often cannot eradicate solid Salmonella can be engineered deliver cytotoxic drugs either trigger an immune response or increase antitumor efficacy when combined with chemotherapeutic drugs. However, the extracellular matrix (ECM) surrounding cells forms a barrier that limits ability of and penetrate eliminate To overcome this limitation, we developed strategy combine...
The rapidly increasing prevalence of obesity and overweight, especially in children adolescents, has become a serious societal issue. Although various genetic environmental risk factors for pediatric overweight have been identified, the problem not solved. In this study, we examined whether nanoplastic (NP) pollutants can act as obesogens using mouse models exposed to NPs derived from polystyrene polypropylene, which are abundant environment. We found abnormal weight gain progeny until 6...

Cells the strains Gram-stain-negative, non-motile, non-spore-forming, coccoid rods, formed non-pigmented colonies. Phylogenetic analysis based 16S rRNA gene sequences revealed that strain Vu-144(T) was affiliated with an uncultivated lineage phylum Bacteroidetes. Its closest phylogenetic...
Although susceptibility to seed shattering causes severe yield loss during cereal crop harvest, it is an adaptive trait for dispersal in wild plants. We previously identified a recessive locus, sh-h, from the rice mutant line Hsh that carries enhanced abscission layer. Here, we further mapped sh-h 34-kb region on chromosome 7 by analyzing 240 F(2) plants and five F(3) lines cross between Blue&Gundil. had point mutation at 3' splice site of seventh intron within LOC_Os07g10690, causing 15-bp...
A Gram-positive and catalase-negative coccus that formed chains, designated strain FP48-3T, isolated from fermented sausage ('mum'), was studied systematically. Strain FP48-3T facultatively anaerobic produced l-lactic acid glucose. Straight-chain fatty acids C18 : 1 C16 0 were the dominant components. The DNA G+C content of 37.9 mol%. On basis 16S rRNA RNA polymerase α-subunit (rpoA) gene sequence analysis, closely related to Enterococcus hirae LMG 6399T, durans 10746T faecium 11423T, with...
A taxonomic study was carried out on two strains that came from kimchi, a traditional Korean fermented-vegetable food. The DNA G+C content of these 37 mol %. Both contained Lys-Ala-Ser in the cell walls. On basis morphological, physiological and chemotaxonomic characteristics, together with data 16S rDNA sequence comparisons DNA-DNA reassociation, it is proposed represent novel species genus Weissella, Weissella koreensis sp. nov. type strain S-5623T (= KCTC 3621T KCCM 41516T = JCM 11263T).
By 16S rDNA sequence analysis, two strains identified previously as members of the genus Nocardioides, namely 'Nocardioides fulvus' IFO 14399 and Nocardioides sp. ATCC 39419, were found to form lines descent distinct from Nocardioides. Therefore, studied taxonomically in detail by phenotypic, particularly chemotaxonomic, characterization, phylogenetic analysis including other related taxa. The genomic DNA G+C contents 'N. 39419 are 70 68 mol%, respectively. contain ll-diaminopimelic acid...
Although many genomic alterations have been observed in lung cancer, their clinicopathologic significance has not thoroughly investigated. This study screened the aberrations across whole genome of non-small cell cancer cells with high-resolution and investigated implications.One-megabase resolution array comparative hybridization was applied to 29 squamous carcinomas 21 adenocarcinomas lung. Tumor normal tissues were microdissected extracted DNA used directly for without amplification. The...
Leuconostoc citreum is one of the most prevalent lactic acid bacteria during manufacturing process kimchi, best-known Korean traditional dish. We have determined complete genome sequence L. KM20. It consists a 1.80-Mb chromosome and four circular plasmids reveals genes likely involved in kimchi fermentation its probiotic effects.
The taxonomic position of a Gram-positive coccus, designated strain CAU 28T, isolated from activated sludge foam was determined by using polyphasic approach. Based on its cellular morphology and the results biochemical tests, 28T identified tentatively as member genus Lactococcus.
