Understanding spatial accommodating responses during plant development

Plant Cell Biology

Osmotically-driven turgor pressure of plant cells can be higher than that of a car tire. It puts tremendous forces onto cell walls and drives changes in cell shape. This has given rise to unique mechanisms to control organ formation in comparison to metazoans. The fascinating interplay between forces and local cellular reorganization is poorly understood. Growth of lateral roots is a prominent example of a developmental process in which mechanical forces between neighboring cells are generated. Lateral roots grow from a single cell layer that resides deep within the primary root. On its way out, lateral roots grow through the overlying endodermal, cortical and epidermal cell layers. We recently demonstrated that endodermal cells actively accommodate lateral root formation. Responses include a dramatic volume loss and a controlled degradation of their lignin-based paracellular diffusion barrier. The lateral root system provides a unique opportunity to elucidate the molecular and cellular mechanisms how mechanical forces and intercellular communication regulate spatial accommodation during plant development.
