摘要

摘要揭示并分析了一株新的卤代古细菌 Halorubrum distributum ICIS4 的完整基因组序列。该菌株是从一种长期在实验室条件下培养的产胡萝卜素微藻（Dunaliella salina）中分离出来的。其基因组（3.32 Mb）包含 3236 个编码蛋白质的基因。在 2817 组同源基因中，有 11 组是该菌株独有的。在基因组中，发现了负责利用甘油和淀粉以及合成维生素、色素和苷元的基因。这些基因可能参与形成和维持与微藻的联系。在基因组组装中发现了一个类似于 HRPV9 病毒的区域和另一个类似于卤虫 Haloquadratum walsbyi 的噬菌体的环状等位基因。

The Genome of a New Halorubrum distributum Strain ICIS4 Isolated from the Culture of a Microalga Dunaliella salina

Abstract

The complete genome sequence of a new strain of the haloarchaeaon Halorubrum distributum ICIS4 was revealed and analyzed. The strain was isolated from a culture of a carotenogenic microalga Dunaliella salina maintained in laboratory conditions for a long period of time. The genome (3.32 Mb) contained 3236 protein-coding genes. Of the 2817 groups of homologous genes, 11 were unique to this strain. In the genome, the genes were revealed, which were responsible for utilization of glycerol and starch and for synthesis of vitamins, pigments, and siderophores. These genes may be involved in formation and maintenance of the association with microalgae. A region similar to the HRPV9 virus and another circular contig similar to a phage of the haloarchaeon Haloquadratum walsbyi were revealed in the genome assembly.
