Root development: A new player integrates two old friends

Curr Biol. 2024 Nov 18;34(22):R1142-R1144. doi: 10.1016/j.cub.2024.09.057.

Abstract

SCARECROW and SHORTROOT are key regulators of middle cortex formation in Arabidopsis roots, and gibberellin plays a crucial role in determining the timing of this process. A new study has filled the gap between these core regulators and elucidated the detailed molecular mechanisms.
