Abstract
Reactivation of cell division is crucial for the regeneration of damaged tissues, which is a fundamental process across all multicellular organisms. However, the mechanisms underlying the activation of cell division in plants during regeneration remain poorly understood. Here, we show that single-cell endodermal ablation generates a transient change in the local mechanical pressure on neighboring pericycle cells to activate patterned cell division that is crucial for tissue regeneration in Arabidopsis roots. Moreover, we provide strong evidence that this process relies on the phytohormone ethylene. Thus, our results highlight a previously unrecognized role of mechano-chemical control in patterned cell division during regeneration in plants.
期刊介绍：
Developmental Cell, established in 2001, is a comprehensive journal that explores a wide range of topics in cell and developmental biology. Our publication encompasses work across various disciplines within biology, with a particular emphasis on investigating the intersections between cell biology, developmental biology, and other related fields. Our primary objective is to present research conducted through a cell biological perspective, addressing the essential mechanisms governing cell function, cellular interactions, and responses to the environment. Moreover, we focus on understanding the collective behavior of cells, culminating in the formation of tissues, organs, and whole organisms, while also investigating the consequences of any malfunctions in these intricate processes.
