植物形态的可塑性是为了最大限度地适应当前的环境条件而进化的。叶子的结构可以最大限度地吸收光线，而向开花的过渡可以加速或延迟，以提高个体的适应性。光是最重要的环境信号之一，植物利用光进行光合作用并将其作为环境信号。植物利用不同的光感受器感知不同波长的光。LED技术的最新进展现在可以在商业规模上操纵光质量，并且现在存在这样的机会，利用植物的发育可塑性，通过精确操纵作物的照明制度来提高作物的产量和质量。本文将讨论植物如何感知和响应光，并考虑如何操纵这些特定的信号通路来提高作物产量和质量。作物的产量和质量可以通过操纵它们的光感受器来提高。英国埃塞克斯大学（University of Essex）的马修·琼斯（Matthew Jones）回顾了有关植物对不同波长光的反应以及如何操纵光感受器通路以改善商业作物的最新研究。植物含有多种光感受器，每种光感受器对不同波长的光作出反应，从而启动影响植物生长发育的细胞途径。这些途径可以导致色素的形成，从而提高果实的质量。它们还在植物对阴影、光照的日常和季节变化以及开花时间的反应中发挥作用。最近经济高效的LED灯的发展可以优化作物生长。然而，不同植物的光感受器及其通路的差异还需要进一步的研究。
The plasticity of plant morphology has evolved to maximize reproductive fitness in response to prevailing environmental conditions. Leaf architecture elaborates to maximize light harvesting, while the transition to flowering can either be accelerated or delayed to improve an individual’s fitness. One of the most important environmental signals is light, with plants using light for both photosynthesis and as an environmental signal. Plants perceive different wavelengths of light using distinct photoreceptors. Recent advances in LED technology now enable light quality to be manipulated at a commercial scale, and as such opportunities now exist to take advantage of plants’ developmental plasticity to enhance crop yield and quality through precise manipulation of a crops’ lighting regime. This review will discuss how plants perceive and respond to light, and consider how these specific signaling pathways can be manipulated to improve crop yield and quality. Crop yields and qualities can be improved by manipulating their photoreceptors with light. Matthew Jones of the UK’s University of Essex reviewed the latest research on plant responses to various wavelengths of light and how photoreceptor pathways can be manipulated to improve commercial crops. Plants contain a variety of photoreceptors, each responding to distinct wavelengths of light to initiate cellular pathways that affect plant growth and development. These pathways can lead to the formation of pigments that improve fruit quality. They also play roles in plant responses to shade, daily and seasonal changes in light, and flowering times. Recent developments in cost-effective LED lights can lead to the optimization of crop growth. However, further research is needed to understand the differences in photoreceptors and their pathways in various plants.
