Plant biology: do DELLAs do defence?

Curr Biol. 2008 Jul 22;18(14):R617-9. doi: 10.1016/j.cub.2008.05.036.

Abstract

DELLA proteins repress plant growth and developmental processes. Recent data suggest that DELLAs improve survival by imposing growth restraint during plant stress, enabling limited resources to be diverted to pathogen defence.
