Endoreplication controls cell size via mechanochemical signaling

Trends Plant Sci. 2023 Jun;28(6):611-613. doi: 10.1016/j.tplants.2023.03.016. Epub 2023 Mar 28.

Abstract

During hypocotyl development, an asymmetric auxin gradient causes differential cell elongation, leading to tissue bending and apical hook formation. Recently, Ma et al. identified a molecular pathway that links auxin with endoreplication and cell size through cell wall integrity sensing, cell wall remodeling, and regulation of cell wall stiffness.

Keywords: apical hook; auxin; cell size; cell wall integrity; endoreplication; pectin.
