摘要: A Gram-positive, non-motile actinomycete, designated strain NEAU-FJL1(T), was isolated from tomato root (Solanum lycopersicum L.) collected from Harbin, Heilongjiang province, north China. The strain formed single spores with smooth surfaces from substrate mycelia. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-FJL1(T) should be affiliated with the genus Plantactinospora and forms a distinct branch with its close neighbour Plantactinospora soyae NEAU-gxj3(T) (99.2% sequence similarity). The cell wall was found to contain meso-diaminopimelic acid and the whole cell sugars were identified as xylose, glucose, arabinose and galactose. The predominant menaquinones were identified as MK-10(H-6) and MK-10(H-4). The phospholipid profile was found to consist of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The major fatty acids were identified as C-15:0, iso-C-16:0, anteiso-C-17:0, C-17:0 and iso-C-15:0. With reference to phenotypic characteristics, phylogenetic data and DNA-DNA hybridization results, strain NEAU-FJL1(T) can be distinguished from its most closely related strain and classified as a new species, for which the name Plantactinospora solaniradicis sp. nov. is proposed. The type strain is NEAU-FJL1(T) (= DSM 100596(T) = CGMCC 4.7284(T)).
