Abstract excerpt

The turnover of abscisic acid (ABA) signaling core components modulates the plant's response to ABA and is regulated by ubiquitination. We show that Arabidopsis (Arabidopsis thaliana) RING Finger ABA-Related1 (RFA1) and RFA4 E3 ubiquitin ligases, members of the RING between RING fingers (RBR)-type RSL1/RFA family, are key regulators of ABA receptor stability in root and leaf tissues, targeting ABA receptors for...
