Two actinomycete strains, designated YIM 56256^T and YIM 61331^T, were isolated from the roots of Scoparia dulcis and Maytenus austroyunnanensis, two Chinese medicinal plants, and their taxonomic status was established based on a polyphasic investigation. The organisms were found to have chemical and morphological markers typical of members of the genus Glycomyces. 16S rRNA gene sequence analysis showed that they were closely related to each other and to Glycomyces sambucus E71^T. A battery of physiological characteristics and levels of DNA–DNA relatedness indicated that strains YIM 56256^T and YIM 61331^T represent two novel species, clearly different from the related known Glycomyces species. On the basis of the data presented, it is evident that each of these strains represents a novel species of the genus Glycomyces, for which the names Glycomyces scopariae sp. nov. (type strain YIM 56256^T =KCTC 19158^T =DSM 44968^T) and Glycomyces mayteni sp. nov. (type strain YIM 61331^T =KCTC 19527^T =CCTCC AA 208004^T) are proposed.

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains YIM 56256^T and YIM 61331^T are EU200682 and EU814511.

Scanning electron micrographs of strains YIM 56256^T and YIM 61331^T and comparisons of fatty acid and menaquinone profiles are available as supplementary material with the online version of this paper.
