title: Phylogenetic analysis of the genera Pseudonocardia and Actinobispora based on 16S ribosomal DNA sequences.
abstract: The 16S rDNA sequences of 11 strains, nine type strains of validated Pseudonocardia species and Actinobispora yunnanensis, and two strains of unnamed Pseudonocardia species, were determined and compared with those of representatives of the family Pseudonocardiaceae. The phylogenetic analysis indicated that all of the validated species of the genera Pseudonocardia and Actinobispora consistently formed a monophyletic unit and separated well from the other genera of the family Pseudonocardiaceae. One unnamed Pseudonocardia strain was related to members of the genus Pseudonocardia, whereas the other unnamed Pseudonocardia strain formed a distinct clade within the radiation of the genus Amycolatopsis.
