摘要： A novel actinomycete, designated strain NEAU-DSCPA1-4-4(T), was isolated from rhizosphere soil of wheat and characterized using a polyphasic approach. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the organism should be assigned to the genus Streptomyces. The strain formed a monophyletic Glade with its closest relatives, Streptomyces ghanaensis DSM 40746(T) (97.7 % 16S rRNA gene sequence similarity) and Streptomyces viridosporus DSM 40243(T) (97.6 %). Similarly, chemotaxonomic data, including major menaquinones, fatty acid compositions and polar lipid profile, also supported the placement of strain NEAU-DSCPA1-4-4(T) in the genus Streptomyces. However, DNA-DNA relatedness, physiological and biochemical data showed that strain NEAU-DSCPA1-4-4(T) could be distinguished from its closest relatives. Therefore, we propose that strain NEAU-DSCPA1-4-4(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces triticisoli sp. nov. is proposed, with NEAU-DSCPA1-4-4(T) (=CCTCC AA 2017025(T) =DSM 105118(T)) as the type strain.
