Complete Genome Sequence of Streptomyces Sp. HSG2 From Rhizosphere Soil of Mangrove in Qingmei Gang, Sanya

Abstract Streptomyces sp. HSG2, was isolated from rhizosphere soil of mangrove forest sampled at Qingmei Gang, Sanya. The complete genome sequence of the strain HSG2 was obtained using PacBio Sequel HGAP.4 and comprised of 5,282,528 base pairs with a 71.9 mol% G + C content, 4504 protein-coding genes, 71 RNAs. In silico analysis confirmed the genes associated with polysaccharide hydrolyzation, hydrocarbon degradation and aerobic denitrification. 24 natural product biosynthesis gene clusters for secondary metabolites were identified as well, including those for Streptobactin and Nystatin A1. The complete genome sequence indicated that Streptomyces sp. HSG2 will provide insight into the biosynthesis and regulatory mechanisms for the secondary metabolites, and propose potential use in biotechnological and novel bioactive natural product biosynthesis applications.
