Research Advances on Phototropin Receptor and Phototropin Signaling Mechanism in Plant

Abstract

Abstract:

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.

Key words: Phototropin, Receptor, Signaling
