Guard cells undergo massive and repeated changed in pressure as they open and close the micropores (stomata) upon which plants depend to balance lost of water against gain of CO2 for photosynthesis. The walls of these cells must have very special mechanical properties and in previous work we identified some of the molecular components of the wall involved (e.g. Current Biology (2022) 32, 3170-3179). Current Biology (2017) 27, 2974-2983). In this project you will take the next step forward to understand the nanoscale how these wall components act to control the mechanical properties of the Arabidopsis guard cell. Combining Atomic Force Microscopy with molecular genetic and enzymatic techniques to alter the wall, you will test the mechanistic link between wall structure and guard cell function.

当保卫细胞打开和关闭微孔（气孔）时，它们会经历巨大且反复的压力变化，植物依靠微孔来平衡光合作用中水分的流失和二氧化碳的增加。这些细胞壁必须具有非常特殊的机械性能，在之前的工作中，我们确定了相关细胞壁的一些分子成分（例如 Current Biology (2022) 32, 3170-3179）。现代生物学 (2017) 27, 2974-2983)。在本项目中，您将进一步了解这些壁成分如何在纳米尺度上控制拟南芥保卫细胞的机械特性。将原子力显微镜与分子遗传学和酶技术相结合来改变壁，您将测试壁结构和保卫细胞功能之间的机械联系。
