A polyphasic approach was used to study the taxonomy of TRM 68085T and the results showed a range of phylogenetic and chemotaxonomic properties consistent with those of the genus Streptomyces . Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TRM 68085T showed the highest similarity value to Streptomyces capitiformicae 1H-SSA4T (98.6 %), and phylogenetically clustered with Streptomyces kanasensis ZX01T(97.5 %) and Streptomyces ipomoeae NBRC 13050T (97.4 %). The genomic DNA G+C content of strain TRM 68085T based on the genome sequence was 71.4 mol%. The levels of DNA–DNA relatedness between the genome of the isolate and its nearest phylogenetic neighbours, S. capitiformicae 1H-SSA4T, S. kanasensis ZX01T and S. ipomoeae NBRC 13050T, were 19.2±0.4, 21.8±0.5 and 19.3±0.6 %, respectively. Chemotaxonomic data revealed that strain TRM 68085T possessed MK-9(H6) and MK-9(H8) as the predominant menaquinones. ll-Diaminopimelic acid and a small amount of meso-diaminopimelic acid were the diagnostic diamino acids. Ribose, xylose, glucose and galactose were the whole-cell sugars. The major cellular fatty acids were C16 : 0 (25.4 %) and iso-C16 : 0 (18.3 %). On the basis of these genotypic and phenotypic data, it is concluded that strain TRM 68085T represents a novel species of the genus Streptomyces , for which the name Streptomyces arboris sp. nov. is proposed. The type strain is TRM 68085T (=CCTCC AA2019031T=LMG 31492T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004430
