Phylogenetic Analyses on the Strains Belonging to Invalidated Genera of the Order Actinomycetales

Abstract

The 16S rRNA gene sequences of invalidly described actinomycetes were determined. Phylogenetic analysis revealed that “Microstreptospora cinerea” and “Trichotomospora caesia” belong to the genus Streptomyces, “Sebekia benihana” and “Cathayosporangium alboflavum” belong to the genus Microtetraspora, and “Streptomycoides glaucoflavus” and “Parvopolyspora pallida” belong to the genus Actinomadura. “Sarraceniospora aurea” is closely related to the genus Actinocorallia. “Asiosporangium albidum” and “Actinoalloteichus cyanogriseus” belong to the family Pseudonocardiaceae. On the basis of its chemotaxonomic properties and phylogenetic analysis, “Actinoalloteichus cyanogriseus” is considered to form a new taxon.
