Light is essential to plant growth and development. It is required for the assimilation of CO2 into usable substrates for plant growth and development as well as for triggering key plant responses such as shade avoidance, developmental changes and seed / fruit production. Currently, multispectral high intensity sodium (HPS) grow-lights represent the standard for plant growth under greenhouse conditions. Despite replicating an approximation of sunlight, these lights lack the required precision to fully replicate key daily events such as dawn and dusk differences in light spectral composition and intensity that exist in nature and vary based on seasonality and geographical location. Moreover, these light conditions often provide more light than needed to maximize growth and development, requiring plants to employ molecular mechanisms to dissipate excess radiation. Edmonton, Alberta based technology company G2V Optics has commercialized a proprietary, programmable-spectra lighting technology aimed at reducing energy inputs for greenhouse food production while also providing a platform for precision plant growth manipulation. Currently, G2V Optics has successfully demonstrated commercially valuable improvements to plants grown with spectral recipes, but lacks an understanding of the underlying micro-level changes occurring within plants that ultimately underpin the benefits of their technology. The company is therefore limited in their ability to rationally apply their lighting technology in a wide array of cultivars and agricultural settings. Our MITACS-ENGAGE-CASBE partnership aims to address this knowledge gap by characterizing the technological and biological capabilities of G2V Optics programmable-spectra lighting technology.**

光对植物的生长和发育至关重要。它是将CO2同化为植物生长和发育所需的有用基质，以及触发关键的植物反应，如避荫、发育变化和种子/果实生产。目前，多光谱高强度钠（HPS）生长灯代表了温室条件下植物生长的标准。尽管复制了近似的阳光，但这些灯缺乏所需的精度来完全复制关键的日常事件，例如自然界中存在的光谱组成和强度的黎明和黄昏差异，并根据季节性和地理位置而变化。此外，这些光照条件通常提供比最大化生长和发育所需的更多的光，这要求植物采用分子机制来消散多余的辐射。总部位于阿尔伯塔的埃德蒙顿技术公司G2 V Optics已将一项专有的可编程光谱照明技术商业化，该技术旨在减少温室食品生产的能源投入，同时还为精确的植物生长操作提供平台。目前，G2 V Optics已经成功地证明了对使用光谱配方种植的植物进行了具有商业价值的改进，但缺乏对植物内部发生的潜在微观变化的理解，这些变化最终支撑了其技术的优势。因此，该公司在合理地将其照明技术应用于各种品种和农业环境的能力有限。我们的MITACS-ENGAGE-CASBE合作伙伴关系旨在通过描述G2 V Optics可编程光谱照明技术的技术和生物能力来解决这一知识差距。**
