Plant-phyllosphere interactions depend on microbial diversity, the plant host and environmental factors. Light is perceived by plants and by microorganisms and is used as a cue for their interaction. Photoreceptors respond to narrow-bandwidth wavelengths and activate specific internal responses. Light-induced plant responses include changes in hormonal levels, production of secondary metabolites, and release of volatile compounds, which ultimately influence plant-phyllosphere interactions. On the other hand, microorganisms contribute making some essential elements (N, P, and Fe) biologically available for plants and producing growth regulators that promote plant growth and fitness. Therefore, light directly or indirectly influences plant-microbe interactions. The usage of light-emitting diodes in plant growth facilities is helping increasing knowledge in the field. This progress will help define light recipes to optimize outputs on plant-phyllosphere communications. This review describes research advancements on light-regulated plant-phyllosphere interactions. The effects of full light spectra and narrow bandwidth-wavelengths from UV to far-red light are discussed.
植物叶际相互作用取决于微生物多样性、植物宿主和环境因素。植物和微生物都能感知光，并将其用作相互作用的信号。光感受器对窄带宽波长作出反应，并激活特定的内部反应。光诱导的植物反应包括激素水平的变化、次生代谢产物的产生以及挥发性化合物的释放，这些最终都会影响植物叶际相互作用。另一方面，微生物有助于使一些必需元素（氮、磷和铁）对植物具有生物可利用性，并产生促进植物生长和健康的生长调节剂。因此，光直接或间接地影响植物与微生物的相互作用。植物生长设施中发光二极管的使用有助于增加该领域的知识。这一进展将有助于确定光配方，以优化植物叶际通讯的产出。本综述描述了光调节植物叶际相互作用的研究进展。讨论了从紫外光到远红光的全光谱和窄带宽波长的影响。
