希瓦氏菌广泛存在于各种环境中。本研究通过对深海沉积物中耐压耐冷铁还原细菌SHWANELLA PERZOTERANS WP3的基因组序列测定和相关功能分析，研究其对环境的适应机制。WP3基因组全长5,396,476个碱基对，4,944个开放阅读框。它拥有大量的基因或基因簇，帮助它应对极端的生存条件，如两套鞭毛系统的基因、结构RNA修饰、二十碳五烯酸(EPA)的生物合成以及渗透调节物质的运输和合成。WP3含有55个开放阅读框，编码可能的c型细胞色素，这对其广泛的环境适应能力是重要的。鉴定并比较了参与不溶性金属还原的mtr-OMC基因簇。这两套鞭毛系统在低温和高压下有不同的调节，侧鞭毛系统是其在低温下活动和生存所必需的。
Shewanella species are widespread in various environments. Here, the genome sequence of Shewanella piezotolerans WP3, a piezotolerant and psychrotolerant iron reducing bacterium from deep-sea sediment was determined with related functional analysis to study its environmental adaptation mechanisms. The genome of WP3 consists of 5,396,476 base pairs (bp) with 4,944 open reading frames (ORFs). It possesses numerous genes or gene clusters which help it to cope with extreme living conditions such as genes for two sets of flagellum systems, structural RNA modification, eicosapentaenoic acid (EPA) biosynthesis and osmolyte transport and synthesis. And WP3 contains 55 open reading frames encoding putative c-type cytochromes which are substantial to its wide environmental adaptation ability. The mtr-omc gene cluster involved in the insoluble metal reduction in the Shewanella genus was identified and compared. The two sets of flagellum systems were found to be differentially regulated under low temperature and high pressure; the lateral flagellum system was found essential for its motility and living at low temperature.
