摘要

新的细菌资源对于研究细菌分类学、细菌进化和新的抗生素、抗肿瘤药物和免疫调节剂的基因组挖掘具有重要价值。在这项研究中,我们对一种新的细菌家族——温度细菌科的菌株进行了重新测序。11月,属假单胞菌门α变形菌纲。该型菌株为中温菌marinus NBRC 110045T,从日本室户市附近0.5 m深度的表层海水中分离得到。这里,菌株NBRC 110045T测序的全基因组由一条长3184799 bp的环状染色体组成,平均G + C含量为43.71%。利用基因组分析揭示其细胞活性的遗传基础。通过细胞调控和信号传导分析,推断其生长温度范围有限的调控机制。温菌科新科的基因组特征可能会扩展我们对海洋细菌的环境适应、遗传进化和天然产物发现的认识。

Complete genome analysis of type strain of a novel bacterial family Temperatibacteraceae fam. nov., isolated from surface seawater

Novel bacterial resources are valuable for studying bacterial taxonomy, bacterial evolution, and genome mining of novel antibiotics, antitumor agents, and immune modulators. In this study, we de novo sequenced the type strain of a novel bacterial family, Temperatibacteraceae fam. Nov., belonging to class Alphaproteobacteria of phylum Pseudomonadota. The type strain, Temperatibacter marinus NBRC 110045T, is mesophilic and was isolated from surface seawater around Muroto city of Japan at a depth of 0.5 m. Here, the sequenced complete genome of strain NBRC 110045T is composed of a circular chromosome of 3,184,799 bp with a mean G + C content of 43.71%. Genome analysis was applied to reveal the genetic basis of its cellular activities. Cellular regulation and signaling was analyzed to infer the regulatory mechanism of its limited growth temperature range. Genomic features of the novel family Temperatibacteraceae may expand our knowledge on environmental adaptation, genetic evolution and natural product discovery of marine bacteria.

期刊介绍: The journal publishes papers on all functional and evolutionary aspects of genes, chromatin, chromosomes and (meta)genomes of marine (and freshwater) organisms. It deals with new genome-enabled insights into the broader framework of environmental science. Topics within the scope of this journal include: • Population genomics and ecology • Evolutionary and developmental genomics • Comparative genomics • Metagenomics • Environmental genomics • Systems biology More specific topics include: geographic and phylogenomic characterization of aquatic organisms, metabolic capacities and pathways of organisms and communities, biogeochemical cycles, genomics and integrative approaches applied to microbial ecology including (meta)transcriptomics and (meta)proteomics, tracking of infectious diseases, environmental stress, global climate change and ecosystem modelling.
