A novel actinomycete, designated strain RP-AC36, was isolated from a cliff-associated plant ( Thunb.) in the Republic of Korea and its taxonomic status was determined by using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequence analysis showed that the organism formed a distinct clade within the radiation of the genus . The chemotaxonomic properties supported the assignment of the isolate to the genus . High levels of 16S rRNA gene sequence similarity were found with (98.2 %), (97.5 %) and (97.1 %). DNA–DNA relatedness data, together with phenotypic differences, clearly distinguished the isolate from its closest relative . Based on the phenotypic and genotypic evidence, it is suggested that the organism be assigned as representing a novel species of the genus for which the name sp. nov. is proposed. The type strain is RP-AC36 (=NRRL B-24662=DSM 45180).
