Abstract:
A novel endophytic actinomycete, designated strain EGI 60009 T , was isolated from the roots of Glycyrrhiza uralensis F. collected from Xinjiang Province, north-west China. The isolate was able to grow in the presence of 0–9 % (w/v) NaCl. Strain EGI 60009 T had particular morphological properties: the substrate mycelia fragmented into rod-like elements and aerial mycelia differentiated into short spore chains. ll -2, 6-Diaminopimelic acid was the cell-wall diamino acid and rhamnose, galactose and glucose were the cell-wall sugars. MK-9(H 4 ) was the predominant menaquinone. The major fatty acids of strain EGI 60009 T were iso-C 15 : 0 , anteiso-C 15 : 0 , anteiso-C 17 : 0 , iso-C 17 : 0 , iso-C 17 : 1 and I/anteiso-C 17 : 0 B. Mycolic acids were absent. The DNA G+C content of strain EGI 60009 T was 70.4 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain EGI 60009 T belongs to the family Jiangellaceae and formed a distinct clade in the phylogenetic tree. 16S rRNA gene sequence similarities between strain EGI 60009 T and other members of the genera Jiangella and Haloactinopolyspora were 96.1–96.4 and 95.7–96.0 %, respectively. Based on these results and supported by morphological, physiological and chemotaxonomic data and numerous phenotypic differences, a novel species of a new genus, Phytoactinopolyspora endophytica gen. nov., sp. nov., is proposed. The type strain of Phytoactinopolyspora endophytica is EGI 60009 T ( = KCTC 29657 T = CPCC204078 T ).
