Abstract
We report a phenomenon similar to catabolite repression in Rhizobium meliloti. Succinate, which allows the highest observed rate of growth of R. meliloti, caused an immediate reduction of beta-galactosidase activity when added to cells growing in lactose. A Lac- mutant was unaltered in nodulation and nitrogen fixation capacities, but a pleiotropic mutant deficient in several catabolic properties was unable to produce effective nitrogen-fixing nodules.Entities:
