摘　　要：Light is a pivotal environmental cue for plant development as well as crop yield,and over many years of study,the basic scheme of light signal transduction has been well established.Light signal is perceived by a group of proteins called photoreceptors which can change their conformation or status after sensing light to initiate downstream signaling cascades[1].One group of photoreceptors are phytochromes,the red(R)/far-red(FR)light photoreceptors,which are encoded by PHYA,PHYB,PHYC,PHYD,and PHYE genes in Arabidopsis[1,2].Phytochromes can switch between two conformational states,the inactive R-absorbing(Pr)form and the active FR-absorbing(Pfr)form,which is light-dependent[2].The switch between Pr and Pfr of phytochromes ensures precise response to light intensity and quality to optimize plant growth under fluctuating light conditions.
