Pseudonocardia kunmingensis sp. nov., an actinobacterium isolated from surface-sterilized roots of Artemisia annua L.
A Gram-positive, aerobic, actinobacterial strain with rod-shaped spores, designated YIM 63158(T), was isolated from the surface-sterilized roots of Artemisia annua L. collected from Yunnan province, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 63158(T) belonged to the genus Pseudonocardia. The closest neighbours were 'Pseudonocardia sichuanensis' KLBMP 1115 (99.9 % 16S rRNA gene sequence similarity), Pseudonocardia adelaidensis EUM 221(T) (99.1 %) and Pseudonocardia zijingensis DSM 44774(T) (98.8 %); sequence similarities to other members of the genus Pseudonocardia ranged from 98.6 to 94.4 %. The chemotaxonomic characteristics, such as the cell-wall diaminopimelic acid, whole-cell sugars, fatty acid components and major menaquinones, suggested that the isolate belonged to the genus Pseudonocardia. The G+C content of the genomic DNA was 73.3 mol%. On the basis of physiological, biochemical and chemotaxonomic data, including low DNA-DNA relatedness between the isolate and other members of the genus Pseudonocardia, it is proposed that strain YIM 63158(T) represents a novel species in this genus, with the name Pseudonocardia kunmingensis sp. nov. The type strain is YIM 63158(T) ( = DSM 45301(T)  = CCTCC AA 208078(T)). [corrected].
