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 G lycomyces scopariae. 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. scopariae indicated 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.
