| 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 ocmA gene, which was predicted to encode an inner membrane protein, was related to production of exopolysaccharides in A. caulinodans. It was also revealed that Lon protease was involved in production of exopolysaccharides. Furthermore, Lon protease was found to be involved in suppression of reb genes, which is related to killer trait of this bacterium.
