摘要: 光作为重要的环境因子之一, 不仅为植物光合作用提供能量, 而且作为信号影响植物对外界环境的响应。该文综述了红光和远红光对植物生长发育和非生物胁迫响应的调控作用, 重点阐述了光敏色素及下游光信号转录因子整合激素等内源信号调控植物种子萌发、下胚轴伸长、芽发育及开花的分子机制, 以及红光和远红光在植物响应盐、干旱及温度胁迫中的作用机制。在挖掘植物感知和响应光环境机理的基础上, 利用LED光谱技术对作物进行精确补光, 有望提高作物产量、品质和抗逆性, 同时推进实现“双碳”目标, 减少能源消耗和环境污染。

关键词: 红光, 远红光, 光敏色素, 植物生长发育, 非生物胁迫

Abstract: As an important environmental factor, light not only provides energy for plant photosynthesis, but also acts as a signal to regulate plant growth and development. Here, we summarize the regulatory effects of red light and far-red light on plant growth and development and abiotic stress responses. This review focuses on the mechanism of phytochrome and light signaling factor regulation of seed germination, hypocotyl growth, bud development, and flowering in plants through integration with endogenous signal transduction, such as hormones. In addition, the regulatory mechanisms of red light and far-red light on plant responses to salt, drought and temperature stress were elucidated. It is expected that on the basis of exploring the mechanism of plant’ perception and response to the light environment, we can accurately supplement light for crops to improve crop yield, quality and stress resistance by using LED spectrum technology while promoting the goal of “dual carbon” to reduce energy consumption and environmental pollution.
