Two Clade A Phosphatase 2Cs Expressed in Guard Cells Physically Interact With...
AbstractBackgroundThe core ABA signaling components functioning in stomatal closure/opening, namely ABA receptors, phosphatases, SnRK2s and SLAC1, are well characterized in Arabidopsis, but their...

AbstractKey messageWe determined the structure of OsPYL/RCAR3:OsPP2C50 complex with pyrabactin. Our results suggest that a less-conserved phenylalanine of OsPYL/RCAR subfamily I is one of...

AbstractRegulation of abscisic acid (ABA) signaling is crucial in balancing responses to abiotic stresses and retaining growth in planta. An ABA receptor (PYL/RCAR) and a protein phosphatase (PP2C), a...

AbstractAbscisic acid (ABA) signaling pathway constitutes a key stress response mechanism in plants. Alternate interaction of a type 2C protein phosphatase (PP2C) with either an ABA receptor or a...

AbstractThe anion channel SLAC1 functions as a crucial effector in the ABA signaling, leading to stomata closure. SLAC1 is activated by phosphorylation in its intracellular domains. Both a...
