Abstract excerpt

A defined insertion mutant of a gene encoding a homolog of the rhizobial C4-dicarboxylate permease (dctA) was constructed in Rhizobium tropici strain CIAT899. This mutant (GA1) was unable to grow on fumarate or malate; however, in contrast with other rhizobial dctA mutants, it retained a limited ability to grow on succinate with ammonia as a nitrogen source. Our results suggest the presence of a novel...
