Abstract: The study of Rhizobium meliloti CXM1-105 and CMX-188 strain Tn5-induced mutants reveals that the mutants enhance higher shoot dry mass upon injection into plants. The Tn5 cotransducible symbiotic effectiveness is due to insertions in megaplasmids 1 and 2. The most efficient mutants increase host shoot dry mass by 23-26% and plant nitrogen by 23-27%.
