Autoinduction plays an important role in intercellular communication among symbiotic and pathogenic gram-negative bacteria. We report here that a nitrogen-fixing symbiont ofPhaseolus vulgaris ,Rhizobium etli CNPAF512, produces at least seven different autoinducer molecules. One of them exhibits a growth-inhibitory effect like that of the bacteriocinsmall [N -(3R -hydroxy-7-cis -tetradecanoyl)-l -homoserine lactone]. At least two of the other autoinducers are synthesized by a LuxI-homologous autoinducer synthase. The correspondingluxI homologous gene (raiI ) and aluxR homolog (raiR ) have been identified and characterized. Enhanced expression ofraiI is dependent on cell density and on the presence of one or more autoinducer molecules synthesized byR. etli CNPAF512. AraiI mutant was shown to release only three different autoinducer molecules; araiR mutant releases four different autoinducer molecules. Examination of different mutants for nodulation of beans showed thatraiI is involved in the restriction of nodule number, whereas nitrogen-fixing activity in terms of acetylene reduction per nodule was not affected.
