A proposal to revive the genus Kitasatospora (Omura, Takahashi, Iwai, and Tanaka 1982)

Int J Syst Bacteriol. 1997 Oct;47(4):1048-54. doi: 10.1099/00207713-47-4-1048.


We determined almost complete 16S ribosomal DNA sequences for 12 actinomycete strains which were either previously classified as Kitasatospora strains or defined as Streptomyces strains but shown to contain major amounts of meso-diaminopimelic acid in their whole-cell hydrolysates. These sequences were subjected to phylogenetic analyses together with the sequences of 34 Streptomyces species. Phylogenetic trees were reconstructed by using both neighbor-joining and maximum-parsimony methods. The Kitasatospora species always formed a stable monophyletic clade. However, the genus Kitasatospora appeared to be either a sister taxon of the genus Streptomyces or a lineage that originated from within Streptomyces species, depending on the outgroup used. Phylogenetic trees were also constructed by using the sequences of the 16S-23S rRNA gene spacers. Streptomyces and Kitasatospora species were consistently recovered as two distinct clades independent of the outgroup used. On the basis of phylogenetic, chemotaxonomic, and phenotypic evidence, we propose that the genus Kitasatospora Omura et al. 1982 should be revived.
