Abstract

 Certain cellular responses to stresses and stimuli are regulated by a G-protein-mediated signaling pathway. A rice dwarf mutant that is defective in the α subunit of the heterotrimeric G-protein was found to be fully protected from blast fungus by the plant activator probenazole (PBZ) despite the 1-day delay in induction of the PR-10 gene PBZ1 by PBZ. These results suggest that the signaling pathway for protection by PBZ is not via the G-protein, although G-protein is involved in the induction of PBZ1 by PBZ.
