Catellatospora tagetis sp. nov., isolated from the root of a marigold (Tagetes erecta L.).


PMID 26111852

Abstract

A Gram-stain positive, non-motile, mesophilic actinomycete, designated strain NEAU-YJC4(T) was isolated from the root of a marigold (Tagetes erecta L.) collected in Heilongjiang Province, northeast China, and characterized using a polyphasic approach. Morphological and chemotaxonomic properties of strain NEAU-YJC4(T) were consistent with the description of the genus Catellatospora. 16S rRNA gene sequence similarity studies showed that strain NEAU-YJC4(T) belongs to the genus Catellatospora, being most closely related to Catellatospora bangladeshensis JCM 12949(T) (98.7 %). Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain NEAU-YJC4(T) formed a monophyletic clade with the closest relative. A combination of DNA-DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-YJC4(T) can be distinguished from C. bangladeshensis JCM 12949(T). Therefore, it is proposed that strain NEAU-YJC4(T) represents a novel species of the genus Catellatospora, for which the name Catellatospora tagetis sp. nov. is proposed. The type strain is NEAU-YJC4(T) (=CGMCC 4.7176(T) = JCM 30053(T)).
