| Outline of Final Research Achievements |
We analyzed the function of the genes and/or proteins involved in flavonoid biosynthesis during fruits development. In this study, we tried to identify the enzyme for gallic acid synthesis, which is one of the major component of proanthocyanidins in astringent persimmon fruits, however, we could not detect the activity. On the other hand, in grape and mango fruits, we identified the several important genes involved biosynthesis of anthocyanins, one of the flavonoids accumulated during mature stage of fruit development instead of proanthocyanidins, and also characterized the enzymes activities for MiUFGT3 and VviPPO2.

| Academic Significance and Societal Importance of the Research Achievements |
植物の生存戦略として幼果期には渋み物資であるプロアントシアニジンを、成熟期には赤や紫などの色を決定するアントシアニンなどのフラボノイドを積極的に蓄積する果実において、同代謝経路の制御機構を解明することは、果実の成熟制御に関する基礎的な知見を与えるとともに、これらを応用した果実生産技術や果実の味、見栄えや機能性といった品質を高めるための育種に応用できると考えられる。
