sp. nov., a daidzein-producing endophyte isolated from a root of D. Don Free

Abstract

A filamentous actinomycete, designated strain D65, was isolated from a root of a wild tree, D. Don (Nepalese Alder), collected in Xishuangbanna, China. It produced the bioactive agents daidzein and -acetyltyramine and had morphological and chemical properties characteristic of streptomycetes. Pink to brownish red diffusible pigments were produced on several ISP media. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain D65 formed a distinct phyletic line that was most closely, albeit loosely, associated with YIM 001, NRRL B-5416, NBRC 12874, NBRC 15428 and NBRC 13473. A number of phenotypic properties allowed differentiation of the strain from related species. Therefore strain D65 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is D65 (=CGMCC 4.3510=NRRL B-24611).
