16S ribosomal DNA analysis of the genera Micromonospora, Actinoplanes, Catellatospora, Catenuloplanes, Couchioplanes, Dactylosporangium, and Pilimelia and emendation of the family Micromonosporaceae.
In order to determine the phylogenetic structure of the actinomycete family Micromonosporaceae, the 16S ribosomal DNA sequences of 17 type species of the genera Actinoplanes, Dactylosporangium, and Pilimelia were compared with the 16S ribosomal DNA sequences of species of the genera Catellatospora, Catenuloplanes, and Couchioplanes and with those of species of the genus Micromonospora and other actinomycete genera for which the sequences have been previously determined. All genera of the family, together with the genera Catellatospora, Catenuloplanes, and Couchioplanes, form a phylogenetically coherent cluster that is well separated from other families of the order Actinomycetales. Except for one species of the genus Catellatospora, all species cluster according to their genus affiliation. The inclusion of the genera Catellatospora, Catenuloplanes, and Couchioplanes into the family broadens the phenotypic and chemotaxonomic heterogeneity of this taxon. An emendation of the family Micromonosporaceae is given.
