We have obtained several results as followers.(1)Blue light specific site (cells) in maize coleoptiles are suggested to be outer cell layers of coleoptile regions, which are indicated IAA synthesis regions as previous studies. (2) Movement of starch grains in the root tip cells are suggested to be regulate light irradiation, and necessary in light-dependent root gravitropism. (3) Ser291 in Zmphot1 was identified as a low-fluence blue light-induced phosphorylation site that is crucial for the first positive phototropism. (4) RSOsPR10 expression in rice root tips are regulated by cross-talk of plant hormones, such as jasmonate, salicylic acid and maybe IAA. Main results of these studies have been published in international journals.
植物の光屈性の分子レベルの機構に関して新たな知見を得ることができた。一部は、まだ論文投稿中の内容があるが、当初の目標を十分に達成した。今後の世界的な研究の進展に大きく貢献するものである。
