Guard cells on the surface of leaves control the rate of water loss and CO2 uptake by changing stomatal aperture in response to environmental signals such light, CO2, humidity and water status. Guard cells therefore play a major role in determining plant productivity and water use efficiency. This project aims to examine the contribution of guard cell energy and carbon metabolism in mediating stomatal responses to the environment in intact plants through the generation and analysis of transgenic plants with altered guard cell function. This will aid in the development of strategies for direct manipulation of stomatal function.

叶片表面的保卫细胞通过改变气孔开度来控制水分损失和CO2吸收速率，以响应环境信号，如光、CO2、湿度和水分状况。因此，保卫细胞在决定植物生产力和水分利用效率方面起着重要作用。本项目旨在通过产生和分析具有改变的保卫细胞功能的转基因植物来研究保卫细胞能量和碳代谢在介导完整植物气孔对环境的反应中的贡献。这将有助于发展直接操纵气孔功能的策略。
