WebIn summary, stomata guard cells facilitate the mechanical processes of stomatal opening and closure to control gas exchange in plants. It has long been thought that the regulation of internal pressure triggers stomatal opening and closure, but how this internal pressure interacts with the flexible but strong cell wall is still pretty mysterious. WebMar 1, 2002 · Under drought stress conditions, ABA accumulates in leaf tissue, generating a net loss of guard cell turgor that led to stomatal closure, thus reducing transpirational water loss. ABA-induced stomatal closure involves a net increase in guard cell cytoplasmic Ca 2+ concentrations. Furthermore, cADPR, ryanodine receptors, and phospholipases C …
