JF International Journal of Systematic and Evolutionary Microbiology, VO 65 IS Pt_6 SP 1799 OP 1804 DO https://doi.org/10.1099/ijs.0.000180 PB Microbiology Society, SN 1466-5034, AB A novel actinomycete, designated strain NEAU-FHS4T, was isolated from the root of black false hellebore (Veratrum nigrum L.). Strain NEAU-FHS4T formed single spores with smooth surfaces on substrate mycelium. The novel strain contained meso-diaminopimelic as amino acid of the peptidoglycan and xylose and glucose as whole-cell sugars. The predominant menaquinones were MK-10(H6) and MK-10(H8). Mycolic acids were not detected. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol. The predominant cellular fatty acids were iso-C16 : 0, C16 : 0, C18 : 0 and anteiso-C17 : 0. Phenotypic and chemotaxonomic analysis showed that the novel isolate had characteristics typical of members of the genus Plantactinospora . 16S rRNA gene sequence analysis also indicated that strain NEAU-FHS4T belonged to the genus Plantactinospora , with highest sequence similarities to Plantactinospora mayteni YIM 61359T (98.88 %) and Plantactinospora endophytica YIM 68255T (98.85 %). The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the novel strain from the most closely related strains. Based on morphological, chemotaxonomic and phylogenetic data, strain NEAU-FHS4T is considered to represent a novel species of the genus Plantactinospora , for which the name Plantactinospora veratri sp. nov. is proposed. The type strain is NEAU-FHS4T ( = CGMCC 4.7143T = DSM 46718T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000180
