Guard cell SLAC1‐type anion channels mediate flagellin‐induced stomatal closure
During infection plants recognize microbe-associated molecular patterns (MAMPs), and this leads to stomatal closure. This study analyzes the molecular mechanisms underlying this MAMP response and its interrelation with ABA signaling. Stomata in intact Arabidopsis thaliana plants were stimulated with the bacterial MAMP flg22, or the stress hormone ABA, by using the noninvasive nanoinfusion techn...
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 کاملStomatal Closure: The Old Guard Takes Up the SLAC
Flowering plant stomata close through passive dehydration or by active pumping of anions through SLAC, a phospho-activated membrane channel. A new study reports that moss likely utilise this same mechanism, and thus supports an early origin for SLAC-mediated active stomatal control.
متن کاملAquaporins facilitate hydrogen peroxide entry into guard cells to mediate ABA- and pathogen-triggered stomatal closure.
Stomatal movements are crucial for the control of plant water status and protection against pathogens. Assays on epidermal peels revealed that, similar to abscisic acid (ABA), pathogen-associated molecular pattern (PAMP) flg22 requires the AtPIP2;1 aquaporin to induce stomatal closure. Flg22 also induced an increase in osmotic water permeability (Pf) of guard cell protoplasts through activation...
