Abstract excerpt

ABA INSENSITIVE 1 (ABI1) and ABI2 are co-receptors of the phytohormone abscisic acid (ABA). Studies have demonstrated that phosphorylation of multiple amino acids on ABI1/2 augments their ability to inhibit ABA signaling in planta. However, whether and how the dephosphorylation of ABI1/2 is regulated to enhance plant sensitivity to ABA remain unknown. In this study, we identified two protein phosphatases,...
