摘要: A novel endophytic actinomycete with antifungal activity, designated strain NEAU-JXY5(T), was isolated from the root of Parathelypteris beddomei (Bak.) Ching. Strain NEAU-JXY5(T) showed closest 16S rRNA gene sequence similarity to Micromonospora luteifusca GUI2(T) (99.31 %), and phylogenetically clustered with Micromonospora noduli GUI43(T) (99.24 %), 'Micromonospora lycii' NEAU-gq11 (99.19 %), 'Micromonospora zeae' NEAU-gq9 (99.12 %), Micromonospora saelicesensis Lupac 09(T) (98.97 %), Micromonospora vinacea GUI63(T) (98.96 %), 'Micromonospora jinlongensis' NEAU-GRX11 (98.91 %), Micromonospora profundi DS3010(T) (98.77 %), Micromonospora zamorensis CR38(T) (98.76 %), Micromonospora chokoriensis 2-19(6)(T) (98.71 %), Micromonospora lupini Lupac 14N(T) (98.69 %), Micromonospora ureilytica GUI23(T) (98.69 %), Micromonospora violae NEAU-zh8(T) (98.57 %) and Micromonospora taraxaci NEAU-P5(T) (98.37 %). Phylogenetic analysis based on gyrB gene sequences also indicated that the isolate clustered with the above strains except M. violae NEAU-zh8(T). A combination of DNA-DNA hybridization results and some phenotypic characteristics indicated that the strain could be readily distinguished from these closest phylogenetic relatives. Therefore, it is concluded that strain NEAU-JXY5(T) represents a novel species of the genus Micromonospora, for which the name Micromonospora parathelypteridis sp. nov. is proposed. The type strain is NEAU-JXY5(T) (=CGMCC 4.7347(T) = DSM 103125(T))
