Abstract

Pseudoalteromonas sp. CuT4–3, a copper resistant bacterium, was isolated from deep-sea hydrothermal sulfides on the Southwest Indian Ridge (SWIR), is an aerobic, mesophilic and rod-shaped bacterium belonging to the family Pseudoalteromonadaceae (class Gammaproteobacteria, order Alteromonadales). In this study, we present the complete genome sequence of strain CuT4–3, which consists of a single circular chromosome comprising 3,660,538 nucleotides with 41.05% G + C content and two circular plasmids comprising 792,064 nucleotides with 40.36% G + C content and 65,436 nucleotides with 41.50% G + C content. In total, 4078 protein coding genes, 105 tRNA genes, and 25 rRNA genes were obtained. Genomic analysis of strain CuT4–3 identified numerous genes related to heavy metal resistance (especially copper) and EPS production. The genome of strain CuT4–3 will be helpful for further understanding of its adaptive strategies, particularly its ability to resist heavy metal, in the deep-sea hydrothermal vent environment.

从深海热液喷口分离的耐铜细菌 Pseudoalteromonas sp.

从西南印度洋脊（SWIR）深海热液硫化物中分离到的耐铜细菌假交替单胞菌（Pseudoalteromonas sp.）CuT4-3是一种好氧、中嗜酸性、杆状细菌，属于假交替单胞菌科（Gammaproteobacteria，Alteromonadales目）。本研究公布了菌株 CuT4-3 的完整基因组序列，该基因组由一条环状染色体和两条环状质粒组成，前者由 3,660,538 个核苷酸组成，G + C 含量为 41.05%，后者由 792,064 个核苷酸组成，G + C 含量为 40.36%，后者由 65,436 个核苷酸组成，G + C 含量为 41.50%。总共获得了 4078 个蛋白质编码基因、105 个 tRNA 基因和 25 个 rRNA 基因。对菌株 CuT4-3 的基因组分析发现了许多与重金属抗性（尤其是铜）和 EPS 生产相关的基因。菌株CuT4-3的基因组将有助于进一步了解其在深海热液喷口环境中的适应策略，特别是抵抗重金属的能力。

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.
