| Outline of Final Research Achievements |
Phytoalexins are antifungal secondary metabolites produced in response to pathogen infection in higher plants. It has been shown that signal transduction pathways leading to phytoalexin production are regulated by jasmonate (JA)-dependent and JA-independent pathways in rice. In this study, we suggested that the JA-independent pathway functions in the phytoalexin production induced by several abiotic stresses as well as pathogen infection, and that cytokinin functions as a second signal in the JA-independent pathway. In addition, we found cross-talk between JA and CK in the regulation of phytoalexin
