A 16S rRNA gene sequence consisting of 1350 bp from the isolate MCCB248 identified it by BLAST analysis as belonging to the genus Streptomyces, having highest sequence similarity (99%) to the type strain Streptomyces artemisiae YIM 63135. The latter strain was isolated from surface-sterilized tissue of Artemisia annua L., collected in Yunnan Province, southwest China,and described by (Zhao et al. 2010). Moreover, phylogenetic analysis using the neighbor-joining method positioned it in a distinct clade along with Streptomyces artemisiae YIM 63135 (Fig. 4). Accordingly, the isolate MCCB 248 was identified as Streptomyces artemisiae, and hence designated as Streptomyces artemisiae MCCB 248 (GenBank accession number KP313874).Fig. 4Neighbour-joining phylogenetic dendrogram based on 16S rRNA gene sequences showing relationships between the isolated S. artemisiae MCCB 248 and related taxa
