1 Key players in ABA signal transduction include the type 2C protein phosphatases (PP2Cs) ABI1 and ABI2, which act by negatively regulating ABA responses. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
2 Key players in ABA signal transduction include the type 2C protein phosphatases (PP2Cs) ABI1 and ABI2, which act by negatively regulating ABA responses. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
3 RCAR1 was shown to bind ABA, to mediate ABA-dependent inactivation of ABI1 or ABI2 in vitro, and to antagonize PP2C action in planta. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
4 Other RCARs also mediated ABA-dependent regulation of ABI1 and ABI2, consistent with a combinatorial assembly of receptor complexes. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
