    Abstract:
    Two novel Gram-stain positive, spore-forming, aerobic actinomycetes, designated NEAU-PCY-1T and NEAU-PCY-2, were isolated from rhizosphere soil of Urtica urens L. collected from Anshan, Liaoning Province, northeast China. The 16S rRNA gene sequence analysis showed that strains NEAU-PCY-1T and NEAU-PCY-2 exhibited 99.8% similarity with each other and are closely related to Streptomyces abietis DSM 42080T (98.2, 98.3%) and Streptomyces fildesensis DSM 41987T (98.0, 98.1%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the two strains formed a cluster with these two closely related species. Moreover, DNA-DNA hybridization results and some phenotypic, physiological and biochemical properties differentiated the two strains from their close relatives in the genus Streptomyces. Based on a polyphasic taxonomy study, strains NEAU-PCY-1T and NEAU-PCY-2 are considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces urticae sp. nov. is proposed, with NEAU-PCY-1T (= DSM 105115T = CCTCC AA 2017015T) as the type strain.
