| Outline of Final Research Achievements |
The genistein-specific induction of Bradyrhizobium japonicum TetR family structural genes was caused by a repressor function. The multidrug efflux pump of the TetR family could be induced early in the symbiosis and functionally regulate the expression profiles of symbiosis genes by adjusting the intracellular genistein concentration by its efflux having cytotoxicity. The results showed a new paradigm that TetR family plays an important role in symbiosis.
