The new taxonomic marker (hin-region) has been proposed, which gives possibility for Rhizobium bacteria study on “species — group of strains” level. Using this marker the groups of Rhizobium strains were determined, which could not be distinguished with other methods, and these results correlated with evolutionary similarity of the bacteria. The developed approach for creating marker systems allows to carry out effective inventory of inter- and intraspecies genetic diversity of nodulating bacteria and to evaluate perspectives of their use in agriculture. The proposed marker system was used for description of Rhizobium bacteria samples isolated from various ecological-geographical regions of Ukraine.
