Proposed model of the role of PUB10 in ABA signaling pathway. MYC2 is a positive regulator for ABA responses and is activated by ABA. MYC2 directly activates two NAC transcription factor (TF) genes, ANAC019 and ANAC055, and these NAC TFs enhance downstream ABA-responsive gene transcription. PUB10 negatively regulates ABA responses by destabilizing MYC2 protein. PUB10 protein level or activity might be modulated after ABA treatment
