Complete Genome Sequence of Qipengyuania sediminis CGMCC 1.12928T, Shed Light on Its Role in Matter-Cycle and Cold Adaption Mechanism of the Genus Qipengyuania.

Abstract

Qipengyuania sediminis CGMCC 1.12928T, a family member of Erythrobacteraceae, the class of Alphaproteobacteria, was isolated from a borehole sediment sample collected from Qiangtang Basin in Qinghai-Tibetan Plateau, the largest permafrost in China. Understanding bacterial molecular feature may shed light on the ecological strategy in the extreme environment. Here we describe the complete genome sequence and annotation of strain CGMCC 1.12928T, including the complete genome sequence and annotation. The genome of strain CGMCC 1.12928T consist of a single-circular chromosome, comprises 2,416,000bp with an average G + C content of 66.7mol%, and contains 2414 genes; including 2367 CDSs, 44 tRNA genes, as well as one operon of 16S-23S-5S rRNA genes. Genomic properties indicated that strain CGMCC 1.12928T has a relatively smaller genome size and higher G + C content within the family Erythrobacteraceae. In addition, genomic analysis revealed its genome contains multiple function genes responsible for nitrogen, sulfur and phosphorus cycles and explained the cold adaption mechanism. Thus, this strain plays an active role in the biogeochemical cycle in cold niche. The whole-genome of this isolate will widen our understanding of the ecological role of the genus Qipengyuania in permafrost.
