• Inhibitory Effects of Methylglyoxal on Light-Induced Stomatal Opening and Inward K⁺ Channel Activity in Arabidopsis

Abstract

Methylglyoxal (MG) is a reactive aldehyde derived by glycolysis. In Arabidopsis, MG inhibited light-induced stomatal opening in a dose-dependent manner. It significantly inhibited both inward-rectifying potassium (K_in) channels in guard-cell protoplasts and an Arabidopsis K_in channel, KAT1, heterologously expressed in Xenopus oocytes. Thus it appears that MG inhibition of stomatal opening involves MG inhibition of K⁺ influx into guard cells.
