Legume plants acquire effectively the nitrogen nutrition by establishing root nodule symbiosis with rhizobia. Here we characterized the symbiotic mutants of rhizobia in order to identify novel rhizobial factors that are required for the induction of symbiotic reactions on host legume. In this work, we found that rhizobial mutants that are disrupted the genes involved in the purine nucleotide metabolisms do not infect normally to host plant roots and induce only small ineffective nodules. The defect in the nodule development was recovered partially by the exogenous application of plant hormones. Our findings indicate the possibility of that the purine derivatives from rhizobia are involved in infection and nodule development on host plants.
