Abstrakt: We have conducted the analysis of sequences of the 16S rRNA gene and intergenic 16S- 23S rRNA region (ITS) of nodule bacteria of soybean which differ in growth speed and are isolated from soils of Ukraine with different growth rate intensities. As a result we have shown the similarity of strains with an intense growth rate to soybean rhizobia of group USDA 123. The studied strains, as other representatives of this group, possess increased saprophytic competence. The restriction analysis divided all sequences of the intergenic ITS region of soybean rhizobia into two ITS types: the first ITS-type includes strains with an intensive growth rate and the second ITS -type contains strains with a slow grow rate. These types also coincide with their physiological groups. [ABSTRACT FROM AUTHOR]
