Abstract excerpt

Nodulation, rhizospheral, and saprophytic types of competitiveness (NC, RC, and SC, respectively) were studied in the highly active strains CXM1-105 and CXM1-188 of the alfalfa rhizobium Sinorhizobium meliloti. The competitiveness was estimated with the use of markers of antibiotic resistance. It was found that the mutant strain T37, which was characterized by a drastically decreased NC, had higher SC and RC than...
