ABSTRACT
Kushneria phosphatilytica YCWA18T (= CGMCC 1.9149T = NCCB 100306T) was isolated from sediment collected in a saltern on the eastern coast of Yellow Sea in China. The genome was sequenced and comprised of one circular chromosome with the size of 3,624,619 bp and DNA G + C content of 59.13%. A total of 3267 protein-coding genes, 64 tRNA genes and 12 rRNA genes were obtained. Genomic annotation indicated that the genome of K. phosphatilytica YCWA18T had 34 genes involved in phosphorus (P) solubilization/metabolism, e.g., gdh, pqq, phoA, phoD and phoX, which products can convert insoluble P-containing compounds to more bio-available dissolved inorganic P. Comparative genomic analysis of Kushneria strains revealed that gdh, pqq, phoA, phoD and phoX were widely distributed in these strains, indicating the genus Kushneria may play an important role in the P cycle. Additionally, a multitude of salt tolerance genes were detected in the genome of K. phosphatilytica YCWA18T. This study and the genome sequence data will be available for further research and will provide insights into potential biotechnological and agricultural applications of Kushneria strains.
