摘　　要：The changes of turgor pressure in guard cells resulted from the massive fluxes of osmotic ions into and out of guard cells through ion channels and transporters are the main driving force for stomatal movement[1].The massive efflux of diverse osmotic anions are mainly mediated by slow and rapid anion channels for stomatal closure,whereas the influx of K^+,the main osmotic cation andThe changes of turgor pressure in guard cells resulted from the massive fluxes of osmotic ions into and out of guard cells through ion channels and transporters are the main driving force for stomatal movement [1]. The massive efflux of diverse osmotic anions are mainly mediated by slow and rapid anion channels for stomatal closure, whereas the influx of K＋, the main osmotic cation and the counter ion of the diverse anions in guard cells.
