In nature, plants are often exposed to environmental stresses that reduce their growth and survival rates. To better understanding how plants withstand stress conditions, one must learn the specialized mechanisms by which plant cells sense stress signals and activate physiological processes to minimize cellular damage. This project uses interdisciplinary approaches to understand how sub-cellular structures, known as Endoplasmic Reticulum (ER) - Plasma Membrane (PM) Contact Sites, coordinate cellular stress responses by regulating molecular exchanges at the ER-PM interface. The characterization of this adaptive sub-cellular response to stress will provide genetic targets for the future biotechnological development of stress tolerant crops.

在自然界中，植物经常暴露于环境胁迫下，这会降低它们的生长和存活率。为了更好地了解植物如何承受胁迫条件，必须了解植物细胞感知胁迫信号并激活生理过程以最大限度地减少细胞损伤的专门机制。该项目使用跨学科的方法来了解亚细胞结构，即内质网（ER）-质膜（PM）接触位点，如何通过调节ER-PM界面的分子交换来协调细胞应激反应。这种适应性的亚细胞响应压力的特性将提供遗传目标的未来生物技术的发展，耐胁迫作物。
