Analysis effects LED grow lights

项目摘要

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.

Lumenari是一家加拿大公司，位于不列颠哥伦比亚省的里士满。该公司为住宅、园艺和商业用途开发自动化、高品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，更好的光谱控制，并减少了维护。LED生长灯产生窄带波长光的能力也适应不同类型植物的特定照明要求。大量的研究表明，光照的数量和质量都会影响植物的免疫力，其中一个关键问题需要解决的是，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Zhang实验室常规使用不同类型的植物病原体来研究植物的免疫反应。该Engage提案的目标是获得资金，以启动与Lumenari的合作，以测试不同光谱的LED生长灯对植物抵抗细菌，卵菌和真菌病原体的影响。此外，还将探讨光谱对植物免疫反应影响的分子机制。这些研究将为LED生长灯行业提供指导，说明什么样的光谱，强度和照明量将使作物植物在温室行业中获得最大产量，而不会导致对微生物病原体的敏感性。
