| Outline of Final Research Achievements |
The expression of HmFT, HmTFL1-1 and HmTFL1-2 in the leaves of the basal shoots was analyzed for 'Rosea', which had the highest flowering ability (percentage) of the basal shoots, and 'Maihime', the basal shoots of which did not flower in the same investigation. As a result, the expression level of HmFT was higher in April, July, and August in 'Rosea' compared to 'Maihime'. In addition, significantly higher expression levels were observed in 'Rosea' from July to June, compared with April to June. On the other hand, the expression level of HmTFL1-2 was higher in June, July, and August in 'Maihime' compared to 'Rosea'. The difference between the expression patterns of HmFT and HmTFL1-2 observed in the leaves of 'Rosea' and 'Maihime' basal shoots is related to the difference in flowering abolities of 'Rosea' and 'Maihime' basel shoots.

We have now found a gene that can be used as an indicator in the environmental factor for hydrangea perpetual flowering in Indonesia.

| Academic Significance and Societal Importance of the Research Achievements |
アジサイのベーサルシュートの開花性から2つの開花に関わる遺伝子を特定することができた。これらの遺伝子発現を指標にすることで、四季咲き性のアジサイあるいは幼若性が短いアジサイをスクリーニングすることが可能となると考える。また、インドネシアなどの熱帯地域において花木類が休眠せずに四季咲き化するメカニズムについて理解が深まるものと考える。
