Genomic Investigation of a Rhizosphere Isolate, Streptomyces sp. JL1001, Associated with Polygonatum cyrtonema Hua.
In the present study, using genome mining, Streptomyces sp. JL1001, which possesses a leinamycin-type gene cluster, was identified from 14 strains of Streptomyces originating from the rhizosphere soil of Polygonatum cyrtonema Hua. The complete genome of Streptomyces sp. JL1001 was sequenced and analyzed. The genome of Streptomyces sp. JL1001 consists of a 7,943,495 bp chromosome with a 71.71% G+C content and 7315 protein-coding genes. We also identified 36 biosynthetic gene clusters (BGCs) for secondary metabolites in Streptomyces sp. JL1001. Twenty-seven BGCs had low (< 50%) or moderate (50-80%) similarity to other known secondary metabolite BGCs. In addition, a comparative analysis was conducted between the leinamycin-type gene cluster in Streptomyces sp. JL1001 and the biosynthetic gene clusters of leinamycin and largimycin. This study aims to provide a comprehensive analysis of the genomic features of rhizosphere Streptomyces sp. JL1001. It establishes the foundation for further investigation into experimental trials involving novel bioactive metabolites such as AT-less type I polyketides that have important potential applications in medicine and agriculture.
