  4. We show that SnRK2.3 is degradated by 26S proteasome system and abscisic acid (ABA) promotes its degradation. AtPP2-B11 was induced by ABA; knockdown of AtPP2-B11 expression markedly increased ABA sensitivity of plants during seed germination and postgerminative development. These results reveal a novel mechanism through which AtPP2-B11 degrades SnRK2.3 to attenuate ABA signaling and the abiotic stress response.
