摘要
Plants have to cope with the surrounding changing environmental stimuli to optimize their physiological and devel-opmental response throughout their entire life cycle.Light and temperature are two critical environmental cues that fluctuate greatly during day-night cycles and seasonal changes.These two external signals coordinately control the plant growth and development.Distinct spectrum of light signals are perceived by a group of wavelength-specific photoreceptors in plants.PIFs and COP1-HY5 are two predominant signaling hubs that control the expression of a large number of light-responsive genes and subsequent light-mediated development in plants.In parallel,plants also transmit low or warm temperature signals to these two regulatory modules that precisely modulate the responsive-ness of low or warm temperatures.The core component of circadian clock ELF3 integrates signals from light and warm temperatures to regulate physiological and developmental processes in plants.In this review,we summarize and discuss recent advances and progresses on PIFs-,COP1-HY5-and ELF3-mediated light,low or warm temperature signaling,and highlight emerging insights regarding the interactions between light and low or warm temperature signal transduction pathways in the control of plant growth.
