Abstract excerpt
In Rhizobium-legume symbiosis, the plant host controls and optimizes the nodulation process by autoregulation. Tn5 mutants of Rhizobium leguminosarum bv. phaseoli TAL 182 which are impaired at various stages of symbiotic development, were used to examine autoregulation in the common bean (Phaseolus vulgaris L.). Class I mutants were nonnodulating, class II mutants induced small, distinct swellings on the roots,...
