There is an abundant literature about the biological and physiological effects of UV-B light and the signaling and metabolic pathways it triggers and influences. Much less is known about UV-C light even though it seems to have a lot of potential for being effective in less time than UV-B light. UV-C light is known since long to exert direct and indirect inhibitory and damaging effects on living cells and is therefore commonly used for disinfection purposes. More recent observations suggest that UV-C light can also be exploited to stimulate the production of health-promoting phytochemicals, to extent shelf life of fruits and vegetables and to stimulate mechanisms of adaptation to biotic and abiotic stresses. Clearly some of these effects may be related to the stimulating effect of UV-C light on the production of reactive oxygen species (ROS) and to the stimulation of antioxidant molecules and mechanisms, although UV-C light could also trigger and regulate signaling pathways independently from its effect on the production of ROS. Our review clearly underlines the high potential of UV-C light in agriculture and therefore advocates for more work to be done to improve its efficiency and also to increase our understanding of the way UV-C light is perceived and influences the physiology of plants.
关于 UV-B 光的生物学和生理学效应，以及它所引发和影响的信号和代谢途径，已有大量文献记载。尽管 UV-C 光似乎比 UV-B 光更有效，但人们对它的了解要少得多。众所周知，UV-C 光会对活细胞产生直接和间接的抑制和损伤作用，因此常用于消毒目的。最近的观察结果表明，UV-C 光还可用于刺激有益健康的植物化学物质的产生、延长水果和蔬菜的保质期并刺激适应生物和非生物胁迫的机制。显然，其中一些效应可能与 UV-C 光刺激活性氧（ROS）产生以及刺激抗氧化分子和机制有关，尽管 UV-C 光也可以独立于其对 ROS 产生的影响触发和调节信号通路。我们的综述清楚地强调了 UV-C 光在农业中的巨大潜力，因此主张开展更多工作来提高其效率，并增加我们对 UV-C 光被感知和影响植物生理学的方式的理解。
