Outline of Final Research Achievements

Tomatoes are a popular and important horticultural crop among consumers in Japan.Tomato production sites are required to shorten the harvest cycle by promoting flowering. Understanding the mechanism of floral development (differentiation of flower buds) in tomatoes will help in this regard. This study revealed that auxin is involved in the flowering of tomato and auxin biosynthesis inhibitor can control the flowering time in tomato at will.

Academic Significance and Societal Importance of the Research Achievements

オーキシンは植物の成長のあらゆる段階に作用している重要な植物ホルモンである。本研究ではトマトに効果のあるオーキシン生合成阻害剤を開発・合成した。オーキシン生合成阻害剤は、成長途中の一時期に処理することで、処理された成長段階でのオーキシンの作用を解明することが可能となる。今後のトマトにおけるオーキシンの生理作用解明のためのツールとなることが期待できる。
