Model for ABA signaling in plants. PYR/PYL/RCAR, pyrabactin resistance/PYR-like/regulatory components of ABA receptors; PP2C, protein phosphatase 2C; SnRK, SNF1-related protein kinase2; ABF, ABA responsive element binding factor; ABI3/4/5, ABA insensitive 3/4/5. ABI3 and ABI5 proteins physically interact with each other.
