Nitric oxide regulates K + and Cl - channels in guard cells through a subset of abscisic acid-evoked signaling pathways

Abscisic acid (ABA) triggers a complex sequence of signaling events that lead to concerted modulation of ion channels at the plasma membrane of guard cells and solute efflux to drive stomatal closure in plant leaves. Recent work has indicated that nitric oxide (NO) and its synthesis are a prerequisi... View More
