Abstract
【Objective】 The effect of salicylic acid on stomatal movement and K+ channel on plasma membrane of guard cell in Vicia faba L.was studied.【Method】 Vicia faba L.as the material,epidermal strips bioassay and patch clamp were used to study Changes of K+ carrent on plasma meribrane in Vicia guard cells.【Result】 Salicylic acid(SA) can induce stomatal closure with a concentration-dependent manner.DPI 10 μmol/L weakened the effect of SA on stomatal apertures by 45%-60%,which indicated that the generation of H2O2 might be involved in the stomatal closure induced by SA.The voltage-dependent K+-selective channels in the plasma membrane were recorded by whole-cell configureuration by patch clamp.The whole-cell inward K+ currents were inhibited by 70% after 20 min treatment by SA 100 μmol/L.But intracellular application of DPI partly abolished SA-inhibited inward K+ current by 46% after 20 min treatment by SA.【Conclusion】 This indicated that H2O2 mediated SA-induced stomatal closuring by targeting inward K+ channels on plasma membrane.
