Programmed cell death: new role in trimming the root tips

Curr Biol. 2014 May 5;24(9):R374-6. doi: 10.1016/j.cub.2014.03.055.

Abstract

How is a rapid cellular turnover of the lateral root cap achieved in plants to control cap size in the growing root tips? Downstream of ANAC033/SOMBRERO, a highly organized and temporally coordinated cell death program involving BFN1 nuclease-mediated rapid corpse clearance eliminates these cells.
