Analysis of the effects of LED grow lights on plant immunity against pathogens

Lumenari是一家加拿大公司，位于不列颠哥伦比亚省里士满。它为住宅、园艺和商业用途开发自动化、优质和易于使用的发光二极管(LED)照明技术。与传统照明系统相比，LED灯具有更高的效率、更好的频谱控制和更少的维护。LED种植灯产生窄带波长灯的能力也适应了不同类型植物的特定照明要求。以往的研究表明，光的数量和质量都会影响植物的免疫，一个关键的问题是，使用LED生长灯如何影响植物对病原微生物病原体的天然抗性机制。UBC的张实验室经常使用不同类型的植物病原体来研究植物的免疫反应。该项目的目标是获得资金，启动与Lumenari的合作，以测试不同光谱的LED种植灯对植物对细菌、卵菌和真菌病原体的抗性的影响。此外，还将探索光的光谱如何影响植物免疫反应的分子机制。这些研究将为LED种植灯行业提供指导，说明在温室行业中，什么光谱、强度和数量的照明对作物最有利，从而在不导致对微生物病原体敏感的情况下获得最大产量。

Lumenari is a Canadian company located in Richmond, British Columbia. It develops automated,premium-quality and easy-to-use light-emitting diode (LED) lighting technologies for residential, horticulturaland commercial usages. Compared with traditional lighting system, LED lights have increased efficiency,better spectrum control, and reduced maintenance. The ability of LED grow lights to produce narrow-bandwavelength lights also accommodates the specific lighting requirements of different types of plants. Asprevious studies have shown that both quantity and quality of light affect plant immunity, one critical questionneeds to be addressed is how deploying LED grow lights affects plant's natural resistance mechanisms againstpathogenic microbial pathogens.The Zhang lab at UBC uses different types of plant pathogens routinely to study plant immune responses. Thegoal of this Engage proposal is to secure funding to initiate collaboration with Lumenari in order to test theeffects of different spectrums of LED grow lights on plant resistance against bacterial, oomycete and fungalpathogens. In addition, the molecular mechanism of how plant immune responses are affected by the spectrumsof lights will be explored. These studies will provide guidance to the LED grow light industry on whatspectrum, intensity and quantity of lighting would benefit the crop plants the most in the greenhouse industryfor maximum yield without causing susceptibility to microbial pathogens.
