With an ear up against the wall: An update on mechanoperception in arabidopsis.

Abstract

Cells interpret mechanical signals and adjust their physiology or development appropri-ately. 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 re-sponses. Our understanding of how this is achieved is still evolving; however, we can refer to ex-amples 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.
