Partial nucleotide sequences (120 bp) of the 16S rRNA gene (rDNA) containing a variable α region were compared in 89 strains of the genus Streptomyces belonging to eight major clusters of category I in Bergey's Manual of Systematic Bacteriology. Fifty‐seven kinds of partial 16S rDNA sequences were observed among the 89 strains. Forty‐three of the strains were grouped into 11 ‘identity groups’, based on the fact that the strains in each group shared an identical sequence in the 120‐bp region. The results of a phylogenetic analysis based on the 16S rDNA 120‐bp sequences revealed that 60 of the 89 strains could be categorized into seven clusters, each consisting of four or more strains. Based on these observations it was concluded that short nucleotide sequences bearing the variable α region are useful for Streptomyces species identification.
