Outline of Final Research Achievements |
In this study, we focused on the regulatory mechanism of the production of phytoalexins, which are antimicrobial secondary metabolites in rice. OsCOI2 is involved in phytoalexin production in rice. Here, we found OsJAZa and OsJAZb that specifically interact with OsCOI2. We also found that OsJAZb represses the expression of a master transcription factor that regulates phytoalexin production. These results suggest that the OsCOI2-OsJAZb complex is a jasmonic acid receptor regulating phytoalexin production in rice.
