abstract= A Gram-positive, non-motile actinobacterium, designated YIM 65754T, was isolated from the stem of Artemisia annua L., collected from Yunnan province, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YIM 65754T comprised an evolutionary lineage within the genus Rhodococcus . The isolate clustered with Rhodococcus pyridinivorans PDB9T, Rhodococcus gordoniae W 4937T and Rhodococcus rhodochrous DSM 43241T, with which it shared 98.4, 97.9 and 97.8 % 16S rRNA gene sequence similarities, respectively. However, DNA–DNA relatedness demonstrated that strain YIM 65754T was distinct from its closest phylogenetic neighbours. The cell-wall peptidoglycan contained meso-diaminopimelic acid, arabinose, galactose, mannose and glucose (cell-wall chemotype IV). The major menaquinone was MK-8(H2) and the predominant fatty acids were C16 : 0 (27.83 %), iso-C15 : 0 2-OH and/or C16 : 1ω7c (20.21 %) and 10-methyl C18 : 0 (17.50 %). The DNA G+C content was 66.2 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic evidence, the isolate represents a novel species of the genus Rhodococcus , for which the name Rhodococcus artemisiae sp. nov. is proposed; the type strain is YIM 65754T ( = CCTCC AA 209042T = DSM 45380T).,
