As one of the grave environmental hazards, soil salinization seriously limits crop productivity, growth, and development. When plants are exposed to salt stress, they suffer a sequence of damage mainly caused by osmotic stress, ion toxicity, and subsequently oxidative stress. As sessile organisms, plants have developed many physiological and biochemical strategies to mitigate the impact of salt stress. These strategies include altering root development direction, shortening the life cycle, accelerating dormancy, closing stomata to reduce transpiration, and decreasing biomass. Apart from being a prime energy source, light is an environmental signal that profoundly influences plant growth and development and also participates in plants' response to salt stress. This review summarizes the regulatory network of salt tolerance by light signals in plants, which is vital to further understanding plants' adaptation to high salinity. In addition, the review highlights potential future uses of genetic engineering and light supplement technology by light-emitting diode (LED) to improve crop growth in saline-alkali environments in order to make full use of the vast saline land.
作为严重的环境危害之一，土壤盐渍化严重限制了作物的生产力、生长和发育。当植物暴露于盐胁迫时，它们会遭受一系列主要由渗透胁迫、离子毒性以及随后的氧化胁迫引起的损害。作为固着生物，植物已经发展出许多生理和生化策略来减轻盐胁迫的影响。这些策略包括改变根系发育方向、缩短生命周期、加速休眠、关闭气孔以减少蒸腾作用以及减少生物量。除了作为主要的能量来源外，光还是一种深刻影响植物生长和发育的环境信号，并且也参与植物对盐胁迫的响应。本综述总结了光信号在植物中耐盐性的调控网络，这对于进一步理解植物对高盐度的适应性至关重要。此外，该综述强调了未来利用基因工程和发光二极管（LED）补光技术来改善盐碱环境中作物生长的潜在用途，以便充分利用广袤的盐碱地。
