Abstract

Apical hook opening is crucial for seedling establishment and is regulated by unequal distribution of the hormone auxin through unknown mechanisms. In this issue of Developmental Cell, Walia et al.⁴ demonstrate that apical hook opening is an output of tissue-wide forces; auxin and cell wall integrity (CWI) signaling interact to restrict elongation to the concave side of the apical hook.

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.
