Abstract
Three actinomycete strains originating from the surface-sterilized roots of Paris polyphylla were characterized by using a polyphasic approach. Phylogenetic analyses based on the 16S rRNA gene sequence showed that they formed a deep, monophyletic branch in the genus Glycomyces, and were most closely related to the type strains of the species Glycomyces harbinensis and Glycomycesscopariae. Morphological and chemotaxonomic data supported the affiliation of strains CPCC 204357T, CPCC 204354 and CPCC 204355 to the genus Glycomyces. The results of physiological and biochemical tests allowed phenotypic differentiation of strains CPCC 204357T, CPCC 204354 and CPCC 204355 from their closest phylogenetic related species in the genus Glycomyces. Low levels of DNA-DNA relatedness with its closest type strains of G. harbinensis and G. scopariaeindicated that strain CPCC 204357T represent a novel species, for which the name Glycomyces paridis sp. nov. is proposed, with CPCC 204357T (=DSM 102295T=KCTC 39745T) as the type strain.
