This project aims at genetically manipulating sugar sensing pathways in the model C4 grass Setaria viridis, and at replacing sugar sensors in the model C3 crop Oryza sativa (rice) with those from S. viridis. This project expects to elucidate the impact of altered sugar perception on crop photosynthesis and yield. Expected outcomes includes advancing a novel “pull” approach to improve yield in C3 crops by using C4-like sugar sensors to reduce feedback regulation of photosynthesis which in turn limits productivity. This is in contrast to previous ‘push’ approaches aimed at directly increasing photosynthesis. Hence, this project provides significant benefits by contributing to the next green revolution needed to lift agricultural yields.

该项目旨在对模型 C4 草 Setaria viridis 中的糖传感途径进行基因操作，并用来自 S. viridis 的糖传感器取代模型 C3 作物 Oryza sativa（水稻）中的糖传感器。该项目期望阐明糖感知改变对作物光合作用和产量的影响。预期成果包括推进一种新颖的“拉动”方法，通过使用类似 C4 的糖传感器来减少光合作用的反馈调节，从而提高 C3 作物的产量，从而限制生产力。这与之前旨在直接增加光合作用的“推动”方法形成鲜明对比。因此，该项目通过为提高农业产量所需的下一次绿色革命做出贡献而提供了显着的效益。
