摘要：

We examined the involvement of intracellular glutathione (GSH) in methyl jasmonate (MeJA) signaling. The chlorinal-1 (ch1-1) mutation decreased GSH in guard cells and narrowed the stomata! aperture. GSH monoethyl ester increased intracellular GSH, diminishing this phenotype. GSH did not affect MeJA-induced reactive oxygen species production or cytosolic Ca2+ oscillation, suggesting that GSH modulates MeJA signaling downstream of production and oscillation.
