| Outline of Final Research Achievements |
This study was conducted to analyze the differences in the control mechanism of flower induction between mango cultivars and to elucidate the factors that induce flowering other than low temperature, and to obtain useful knowledge for new cultivation method and stable production of mangoes. The results showed that MiFT gene expression was involved in the induction of flowering induced by low temperature in other cultivars as well as in 'Irwin', but MiFT was not involved in summer flowering. In addition, 'Irwin' was found to flower in summer, which is thought to be required low temperature for floral induction. We plan to investigate the mechanism of summer flowering through comprehensive transcriptome analysis.

| Academic Significance and Societal Importance of the Research Achievements |
マンゴーの花成に関して，低温に遭遇せず，また，MiFT遺伝子の発現が増加しなくても花成誘導が進むことが熱帯性品種だけではなく'Irwin'でも確認されたことは興味深い．これまでにマンゴーの花成制御の仮説として広く受け入れられているVP/FP仮説を検証するための足がかりになるであろう．一方，夏季開花の仕組みが解明されれば，マンゴーの新規作型や生産安定化技術の開発に繋がることから，実用的価値も高いと考えている．
