The involvement of intracellular glutathione in methyl jasmonate signaling in Arabidopsis guard cells

Biosci Biotechnol Biochem. 2010;74(12):2504-6. doi: 10.1271/bbb.100513. Epub 2010 Dec 7.

Abstract

We examined the involvement of intracellular glutathione (GSH) in methyl jasmonate (MeJA) signaling. The chlorina1-1 (ch1-1) mutation decreased GSH in guard cells and narrowed the stomatal aperture. GSH monoethyl ester increased intracellular GSH, diminishing this phenotype. GSH did not affect MeJA-induced reactive oxygen species production or cytosolic Ca(2+) oscillation, suggesting that GSH modulates MeJA signaling downstream of production and oscillation.
