Cytosolic abscisic acid activates guard cell anion channels without preceding Ca(2+) signals

The phytohormone abscisic acid (ABA) reports on the water status of the plant and induces stomatal closure. Guard cell anion channels play a central role in this response, because they mediate anion efflux, and in turn, cause a depolarization-induced K(+) release. We recorded early steps in ABA sign...
