Wounding-induced changes in cellular pressure and localized auxin signalling spatially coordinate restorative divisions in roots

ABSTRACT: Wound healing in plant tissues, consisting of rigid cell wall-encapsulated cells, represents a considerable challenge and occurs through largely unknown mechanisms distinctive from animals. Owing to their migration inability, plant cells rely on targeted cell division and expansion to regenerate wounds. Strict coordination of these wound-induced responses is essential to ensure efficient, spatially restricted wound healing. Single cell tracking by live imaging allowed us to gain mechanistic insights into the wound perception and coordination of wound-responses after laser-based wounding in Arabidopsis root. We revealed a crucial contribution of the collapse of damaged cells in wound perception and detected an auxin increase specific to cells immediately adjacent to the wound. This localize
