Abstract

The RNA polymerase -subunit genes () of 67 strains, representing 57 species, five strains and KCTC 9549 were partially sequenced using a pair of PCR primers. Among the streptomycetes, 99·7–100 % similarity within the same species and 90·2–99·3 % similarity at the interspecific level were observed by analysis of the determined sequences. The topology of the phylogenetic tree based on sequences was similar to that of 16S rDNA. The five strains formed a stable monophyletic clade and a sister group to the clade comprising all species. Although there were several discrepancies in the details, considerable agreement was found between the results of analysis and those of numerical phenetic classification. This study demonstrates that analysis of can be used as an alternative genetic method in parallel to conventional taxonomic methods, including numerical phenetic and 16S rDNA analyses, for the phylogenetic analyses of the genera and .
