The core components of the ABA signaling pathway. PYR/PYL/RCAR: pyrabactin resistance/pyrabactin resistance-like/regulatory component of ABA receptors, PP2C: type 2C protein phosphatase (negative regulator), SnRK2: sucrose non-fermenting 1 (SNF1)-related protein kinase 2 (positive regulator), ABF/AREB: ABA-responsive element binding factor/protein, P: phosphorylation.
