This project aims to identify novel and conserved mechanisms that drive the opening of stomata – plant pores that enable CO2 acquisition for photosynthesis. Stomatal movements strongly affect plant productivity and water use efficiency and have profoundly influenced the earth’s climate and terrestrial ecology. This project will address critical gaps in our understanding of how plants open stomata in response to their environment and the evolutionary history of the genes controlling this fundamental process. A major expected outcome is knowledge of the diversity of stomatal opening pathways, which should ultimately lead to improved predictions of plant responses to environmental change and assist future targeted modification of plant growth.

这个项目的目的是确定新的和保守的机制，驱动开放的气孔-植物孔，使二氧化碳的光合作用的收购。气孔运动强烈影响植物的生产力和水分利用效率，并深刻影响地球气候和陆地生态。该项目将解决我们对植物如何打开气孔以应对其环境以及控制这一基本过程的基因的进化历史的理解中的关键差距。一个主要的预期成果是气孔开放途径的多样性的知识，这最终将导致改善预测植物对环境变化的反应，并协助未来有针对性的修改植物生长。
