| Research Abstract |
Azorhizobium caulinodans is a microsymbiont of a tropical legume, Sesbania rostrata, and forms nitrogen fixing nodules on the stems. In this study, it was revealed that praR gene of A. caulinodans was involved in suppression of reb genes, and that an A. caulinodans praR mutant exhibiting high expression of reb genes changed from a symbiont to a pathogen. It was also found that an A. caulinodans mutant taking up potassium in ATP-dependent manner formed stem-nodules showing nitrogen fixation.
