摘要
向光素(phototropin,PHOT)是继光敏色素、隐花色素之后分离的植物蓝光受体。PHOT介导蓝光诱导的向光反应,叶绿体运动,气孔开放、叶片伸展及叶片定位等生理反应。近年来关于PHOT受体介导这些生理反应的分子机制探讨愈来愈受研究者的广泛关注。主要从拟南芥PHOT结构及信号转导方面的研究进展进行综述。
Phototropin（PHOT）is blue-light receptors found following the phytochrome and cryptochrome in plant. PHOT mediate phototropism,chloroplast movement,stomatal opening,leaf expansion and leaf positioning induced by blue-light in higher plants. Research on molecular mechanism of physiological response mediated by PHOT were highly focused in recent years. This paper reviewed research advances of structure characteristics of light sensitivity and signaling mechanism of Arabidopsis phototropin.
