Abscisic 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 کاملEthylene 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 کاملRegulation of abscisic acid-induced stomatal closure and anion channels by guard cell AAPK kinase.
Abscisic acid (ABA) stimulates stomatal closure and thus supports water conservation by plants during drought. Mass spectrometry-generated peptide sequence information was used to clone a Vicia faba complementary DNA, AAPK, encoding a guard cell-specific ABA-activated serine-threonine protein kinase (AAPK). Expression in transformed guard cells of AAPK altered by one amino acid (lysine 43 to al...
متن کاملAbscisic acid (ABA)- and methyl jasmonate (MeJA)-induced stomatal closure are accompanied by cytosolic alkalization
stomatal closure are accompanied by cytosolic alkalization in guard cells. However, it remains to be clarifi ed how the alkalization functions in not only ABA signaling but also MeJA. We investigated cytosolic alkalization in guard cells during ABA-, MeJAand Ca 2 + -induced stomatal closure of wild type, abi1-1 , abi2-1 , ost1-2 and coi1 using a pHsensitive fl uorescent dye, BCECF-AM. ABA induc...
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...
