Cells interpret mechanical signals and adjust their physiology or development appropriately. In plants, the interface with the outside world is the cell wall, a structure that forms a continuum with the plasma membrane and the cytoskeleton. Mechanical stress from cell wall damage or deformation is interpreted to elicit compensatory responses, hormone signalling, or immune responses. Our understanding of how this is achieved is still evolving; however, we can refer to examples from animals and yeast where more of the details have been worked out. Here, we provide an update on this changing story with a focus on candidate mechanosensitive channels and plasma membrane-localized receptors.
细胞能够解读机械信号并相应地调整其生理状态或发育过程。在植物中，与外界的界面是细胞壁，它是一种与质膜和细胞骨架形成连续体的结构。细胞壁损伤或变形产生的机械应力会引发补偿反应、激素信号传导或免疫反应。我们对这一过程的实现方式的理解仍在不断发展；然而，我们可以参考动物和酵母中的例子，其中更多细节已被阐明。在这里，我们重点介绍候选机械敏感通道和质膜定位受体，对这个不断变化的故事进行更新。
