The Ascorbic Acid Redox State Controls Guard Cell Signaling and Stomatal Movement

H(2)O(2) serves an important stress signaling function and promotes stomatal closure, whereas ascorbic acid (Asc) is the major antioxidant that scavenges H(2)O(2). Dehydroascorbate reductase (DHAR) catalyzes the reduction of dehydroascorbate (oxidized ascorbate) to Asc and thus contributes to the re...
