Ethylene inhibits abscisic acid-induced stomatal closure in Arabidopsis.
To examine the cross talk between the abscisic acid (ABA) and ethylene signal transduction pathways, signaling events during ABA-induced stomatal closure were examined in Arabidopsis (Arabidopsis thaliana) wild-type plants, in an ethylene-overproducing mutant (eto1-1), and in two ethylene-insensitive mutants (etr1-1 and ein3-1). Using isolated epidermal peels, stomata of wild-type plants were f...
متن کاملAbscisic acid-induced stomatal closure mediated by cyclic ADP-ribose.
Abscisic acid (ABA) is a plant hormone involved in the response of plants to reduced water availability. Reduction of guard cell turgor by ABA diminishes the aperture of the stomatal pore and thereby contributes to the ability of the plant to conserve water during periods of drought. Previous work has demonstrated that cytosolic Ca2+ is involved in the signal transduction pathway that mediates ...
متن کاملCooperative Function of PLDd and PLDa1 in Abscisic Acid-Induced Stomatal Closure in Arabidopsis
Phospholipase D (PLD) is involved in responses to abiotic stress and abscisic acid (ABA) signaling. To investigate the roles of two Arabidopsis (Arabidopsis thaliana) PLDs, PLDa1 and PLDd, in ABA signaling in guard cells, we analyzed ABA responses in guard cells using Arabidopsis wild type, plda1 and pldd single mutants, and a plda1 pldd double mutant. ABA-induced stomatal closure was suppresse...
متن کاملHydrogen peroxide is involved in abscisic acid-induced stomatal closure in Vicia faba.
One of the most important functions of the plant hormone abscisic acid (ABA) is to induce stomatal closure by reducing the turgor of guard cells under water deficit. Under environmental stresses, hydrogen peroxide (H(2)O(2)), an active oxygen species, is widely generated in many biological systems. Here, using an epidermal strip bioassay and laser-scanning confocal microscopy, we provide eviden...
متن کاملInvolvement of endogenous abscisic acid in methyl jasmonate-induced stomatal closure in Arabidopsis.
In this study, we examined the involvement of endogenous abscisic acid (ABA) in methyl jasmonate (MeJA)-induced stomatal closure using an inhibitor of ABA biosynthesis, fluridon (FLU), and an ABA-deficient Arabidopsis (Arabidopsis thaliana) mutant, aba2-2. We found that pretreatment with FLU inhibited MeJA-induced stomatal closure but not ABA-induced stomatal closure in wild-type plants. The ab...
