| Outline of Final Research Achievements |
Jasmonate (JA) is a plant hormone regulating abiotic and biotic stress responses and growth. In this study, we analyzed the physiological and biochemical functions of CYP94D1, CYP94D2, and ILL6 proteins, which were predicted to inactivate the JA signal. In the analysis of mutant plants with higher and lower expression levels of CYP94D1 than wild type plant, we observed phenotypic differences. The transgenic plants lucking CYP94D1 showed higher resistance to external JA. The overexpressing plants of CYP94D1 accumulate higher level of tuberonic acid glucoside than wild type.
