Phytochromes are receptors for red light (R)/far-red light (FR), which are not only involved in regulating the growth and development of plants but also in mediated resistance to various stresses. Studies have revealed that phytochrome signaling pathways play a crucial role in enabling plants to cope with abiotic stresses such as high/low temperatures, drought, high-intensity light, and salinity. Phytochromes and their components in light signaling pathways can also respond to biotic stresses caused by insect pests and microbial pathogens, thereby inducing plant resistance against them. Given that, this paper reviews recent advances in understanding the mechanisms of action of phytochromes in plant resistance to adversity and discusses the importance of modulating the genes involved in phytochrome signaling pathways to coordinate plant growth, development, and stress responses.
光敏色素是红光（R）/远红光（FR）的受体，不仅参与调控植物的生长和发育，还介导对各种胁迫的抗性。研究表明，光敏色素信号通路在植物应对非生物胁迫（如高低温、干旱、强光和盐度）方面发挥着关键作用。光敏色素及其在光信号通路中的组成部分也可以响应由昆虫和微生物病原体引起的生物胁迫，从而诱导植物对它们产生抗性。鉴于此，本文综述了近年来对光敏色素在植物逆境抗性中的作用机制的理解进展，并讨论了调节参与光敏色素信号通路的基因以协调植物生长、发育和应激反应的重要性。
