abstract= An endophytic actinomycete, strain YIM 65188T, was isolated from surface-sterilized tissue of Sedum sp. collected from Yunnan province, south-west China, and characterized by using a polyphasic approach. Analysis of the 16S rRNA gene sequence showed that strain YIM 65188T is a member of the genus Streptomyces and exhibited 97.5 and 96.3 % gene sequence similarities to Streptomyces specialis GW41-1564T and Streptomyces hainanensis YIM 47672T, respectively, whereas low sequence similarity values (<95.2 %) distinguished strain YIM 65188T from all other Streptomyces species with validly published names. Strain YIM 65188T had a unique menaquinone composition, with the predominant quinones being MK-11(H6) and MK-10(H6), with moderate amounts of MK-10(H8), MK-11(H8), MK-9(H8), MK-11(H4), MK-9(H6) and MK-10(H4). Similarly, the closest phylogenetic relative, S. specialis GW41-1564T, also had an unusual quinone composition, with the predominant menaquinones MK-10(H4) and MK-10(H6) and minor amounts of MK-9(H4) and MK-9(H6). The DNA–DNA hybridization value between strain YIM 65188T and S. specialis GW41-1564T was 42.7 %. On the basis of phenotypic and phylogenetic characteristics, strain YIM 65188T was identified as a novel species of the genus Streptomyces for which the name Streptomyces sedi sp. nov. is proposed, with YIM 65188T (=CCTCC AA 208020T =DSM 41942T) as the type strain.,
