Heterotrimeric G protein signaling is required for epidermal cell death in rice.

Plant physiology - 1 Oct 2009

Steffens Bianka, Sauter Margret

Abstract excerpt

In rice (Oryza sativa) adventitious root primordia are formed at the nodes as part of normal development. Upon submergence of rice plants, adventitious roots emerge from the nodes preceded by death of epidermal cells above the root primordia. Cell death is induced by ethylene and mediated by hydrogen peroxide (H(2)O(2)). Pharmacological experiments indicated that epidermal cell death was dependent on signaling...
