英文摘要	Psychrobacter has been regarded as an important genus for bacterial cold adaptation studies. However, members of this genus are highly varied in terms of both cold adaptability and genome content. To get an understanding of the diversity of members of this genus, five Psychrobacter strains (G, K5, 273-4, PAMC21119 and PRwf-1), with publicly available complete/draft genome, were selected and comprehensive comparative genomics analyses were performed among them. The closest phylogenetic relationship, highest average nucleotide identity (96.78%) and best sequence synteny were identified between strains G and K5. These findings suggest they belong to the same species, despite the long geographic distance between them (Antarctic and Siberia). 4542 gene clusters in total were identified from the five genomes, and of which 1424 were shared by all of them. The number of genes unique to strains G, K5, 273-4, PAMC21119 and PRwf-1 are 183, 188, 300, 637 and 665, respectively. COG assignment revealed their differences in gene content related to stress response. The extensive sequence rearrangements and the large number of genes unique to strain PAMC21119 and PRwf-1 suggest they may have experienced a high level of gene exchanges in the permafrost soil and the surface of fish skin.
