| Outline of Final Research Achievements |
Although bacterial wilt is an important disease of solanaceous crops, there is little knowledge about resistance genes. We searched for eggplant lines collected from worldwide for bacterial wilt resistance, and found the eggplant line No. 98 with strong bacterial wilt resistance. The No. 98 line recognized an Avr effector from phylotype I Ralstonia solanacearum and exhibited strong resistance. We also succeeded in identifying an Avr effector from phylotype IV Ralstonia solanacearum that is recognized by eggplant and induces hypersensitive responses. Crossing experiments strongly suggested that the two bacterial wilt resistance genes found in this study were both dominant and considered to be NBS-LRR resistant protein genes.
