Morphological and chemotaxonomic characteristics of the two strains coincided with those of the genus Streptomyces . The 16S rRNA gene sequence analysis showed that the two isolates exhibited 99.6 % 16S rRNA gene sequence similarity with each other and that they were most closely related to Streptomyces violaceorectus DSM 40279T (98.8, 99.0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the two strains clustered together and formed a separate subclade. Furthermore, a combination of DNA–DNA hybridization results and some physiological and biochemical properties demonstrated that the two strains could be distinguished from its closest relative. Therefore, it is proposed that strains NEAU-A4T and NEAU-A3 should be classified as representatives of a novel species of the genus Streptomyces , for which the name Streptomyces tritici sp. nov. is proposed. The type strain is NEAU-A4T (=CGMCC 4.7393T=DSM 104540T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002493
