Rossellomorea sp. y25, a putative new species of yellow pigment-producing, aerobic and chemoheterotrophic bacterium belonging to the family Bacillaceae, was isolated from the sediments at the depth of 1829 m in the South China Sea. In this study, we present the complete genome sequences of strain y25, which consisted of only one circular chromosome with 4,633,006 bp and the content of G + C was 41.76%. A total of 4466 CDSs, 106 tRNA, 33 rRNA, and 101 sRNA genes were obtained. Genomic analysis of strain y25 showed that it has the ability to produce antioxidant carotenoids and a large number of heavy metal resistance genes, such as arsenic, cadmium and zinc. In addition, strain y25 contains a prophage that may contribute to host protection against lysis by related Bacillus-like phages. This is the first report of genome-wide information on a bacterium of the genus Rossellomorea isolated from the deep sea, providing insights into how microorganisms of this genus adapt to deep-sea environments.
罗斯洛莫雷亚属 y25 株，一种潜在的产黄色素、需氧和化能异养新细菌，属于芽孢杆菌科，是从南海 1829 米深处的沉积物中分离出来的。在本研究中，我们介绍了菌株 y25 的完整基因组序列，它只由一条环状染色体组成，长度为 4633006bp，G+C 含量为 41.76%。共获得 4466 个 CDS、106 个 tRNA、33 个 rRNA 和 101 个 sRNA 基因。y25 株的基因组分析表明，它具有产生抗氧化类胡萝卜素和大量重金属抗性基因的能力，如砷、镉和锌。此外，y25 菌株含有一个前噬菌体，可能有助于宿主免受相关芽孢杆菌样噬菌体的裂解。这是首次报道从深海分离的罗斯洛莫雷亚属细菌的全基因组信息，为该属微生物如何适应深海环境提供了新的见解。
