Outline of Final Research Achievements |
The aim of this study is to clarify regulation mechanism of plant vitamin C biosynthesis in response to light. We have done molecular physiological analyses using Arbidopsis, tomato, and moss plants, and concluded that photosynthesis electron transport system is working as a trigger for light dependent vitamin C synthesis. In addition, we obtained some experimental evidences that the key regulatory factors contribution downstream of this trigger is VTC2 and VTC3, encoding GDP-L-galactose phosphorylase and a novel protein kinase/phosphatase, respectively.
