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，植物经常暴露在环境压力下，从而降低它们的生长和存活率。为了更好地了解植物如何抵御逆境，人们必须了解植物细胞感知逆境信号并激活生理过程以将细胞损害降至最低的专门机制。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)接触部位，如何通过调节ER-PM界面上的分子交换来协调细胞应激反应。这种对逆境的适应性亚细胞反应的特征将为未来耐逆作物的生物技术发展提供遗传靶点。
