摘　　要：光是植物重要的能量来源和环境信号,对植物生长发育的多个过程都起着重要的调节作用。植物由于固着生长的特性,必须时刻感知及监测周围环境变化,以调整自身生长发育模式,才能在自然界得以生存。近年的研究表明,植物会根据环境的光信号调整其对非生物逆境胁迫信号的响应,同时植物也要面对诸如强光、紫外线及遮荫等光胁迫信号。本文综述了近年来光信号调控植物响应非生物逆境胁迫(包括高低温、干旱、盐等)的研究进展,并提出了未来研究的重要科学问题。深入揭示植物对光与非生物逆境胁迫信号的协同响应机制,有助于进一步理解植物环境适应性的调控机制,为提高作物的光能利用效率及抗逆性提供理论指导。Light not only provides the energy source for photosynthesis,but also serves as an important environmental signal regulating many processes of plant growth and development.Due to the sessile nature,plants must constantly sense and monitor the changes in the surrounding environment,coordinately adjusting their growth and development to obtain a better chance of survival.Plants must deal with light stresses such as strong light,ultraviolet light and shade,and notably,accumulating evidence shows that plants adjust their responses to environmental stresses according to their light conditions.In this review,we summarize recent research progress on how plants respond to light stresses and how light regulates plant responses to abiotic stresses(including high or low temperatures,drought,and salinity).We also discuss the questions that are crucial for a further understanding of the crosstalk between light and abiotic stress response pathways in plants for future research.Undoubtedly,further investigation and ultimate elucidation of these questions and others will not only shed more light on how plants respond coordinately to their environmental signals,but also facilitate the molecular design and breeding of the crop varieties with improved solar energy utilization efficiency and enhanced stress tolerance.
