As a second messenger, H2O2 generation and signal transduction is subtly controlled and involves various signal elements, among which the members of MAP kinase family. The increasing evdences indicated that both MEK1/2 and p38-like MAP protein kinase have been shown to mediate ABA-induced H2O2 signaling in plant cells. Here we analyze the mechanisms of similarity and difference between MEK1/2 and p38-like MAP protein kinase in mediating ABA-induced H2O2 generation, inhibition of inward K+ currents, and stomatal closure, suggesting that activation of MEK1/2 is prior to p38-like protein kinase in Vicia guard cells.
