sp. nov., an endophyte isolated from surface-sterilized leaves of an apricot tree () Free

Abstract

A member of the genus , designated PIP 143, was isolated from the leaves of an Australian native apricot tree (). The isolate was a Gram-reaction-positive, aerobic actinobacterium, with a well-developed substrate mycelium that fragmented into small rods. Phylogenetic evaluation based on 16S rRNA gene sequences placed the isolate in the family . Strain PIP 143 was most closely related to I06-2230 (98.7 %) and YIM 45725 (98.1 %). Chemotaxonomic data, including cell-wall components, menaquinones and fatty acids, confirmed the affiliation of strain PIP 143 to the genus Phylogenetic analysis and physiological and biochemical studies, in combination with DNA–DNA hybridization studies, allowed the differentiation of strain PIP 143 from its closest phylogenetic neighbours with validly published names. Therefore, a novel species is proposed, with the name sp. nov. The type strain is PIP 143 ( = DSM 45354  = ACM 5288  = NRRL B-24810).
