A study of the competitive properties of the aluminum-tolerant strain Rhizobium leguminosarum bv. trifolii 9-4A by the antibiotic resistance method

A study of the competitive properties of the aluminum-tolerant strain Rhizobium leguminosarum bv.... The virulence, competitive ability, and symbiotic efficiency of 2 Rhizobium leguminosarum bv. trifolii strains—the wild aluminum tolerant strain 9-4A and the commercial strain 348a—were compared when introducting their variants marked with antibiotic resistance into the rhizosphere of red clover (Trifolium pratense L.) plants. High virulence and competitive ability of the strain tolerant to aluminum was demonstrated by a concurrent inoculation of the seeds with these two strains. The resistance acquisition by the commercial strain was accompanied by a decrease in its symbiotic efficiency. Presumably, the resistant variant of aluminum-tolerant isolate retains its symbiotic properties due to its adaptation to acidity factors at the level of membrane function. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

The virulence, competitive ability, and symbiotic efficiency of 2 Rhizobium leguminosarum bv. trifolii strains—the wild aluminum tolerant strain 9-4A and the commercial strain 348a—were compared when introducting their variants marked with antibiotic resistance into the rhizosphere of red clover (Trifolium pratense L.) plants. High virulence and competitive ability of the strain tolerant to aluminum was demonstrated by a concurrent inoculation of the seeds with these two strains. The resistance acquisition by the commercial strain was accompanied by a decrease in its symbiotic efficiency. Presumably, the resistant variant of aluminum-tolerant isolate retains its symbiotic properties due to its adaptation to acidity factors at the level of membrane function.
