Abstract: Abscisic acid (ABA) plays a key role in the growth, development and stress condition of plants. The process of plant response to ABA is completed by signal recognition, transduction, and response cascades. The core ABA signaling pathway consists of receptor RCAR/PYR/PYLs, phosphatase PP2Cs, kinase SnRK2s, and transcription factors and ion channel proteins. Post-translational modifications (PTMs) of proteins such as phosphorylation, ubiquitination, small ubi- quitin-related modifier (SUMOylation) and redox modifications plays an important role in ABA signaling. This review focused on the role of modifications in the core ABA signaling pathway.

Key words: ABA, phosphorylation, PTMs, redox, SUMOylation, ubiquitination
