1 Identification of an important site for function of the type 2C protein phosphatase ABI2 in abscisic acid signalling in Arabidopsis. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
2 It is known that the clade A protein phosphatase 2Cs (PP2Cs), including ABI1 and ABI2 and other PP2C members, are key players that function directly downstream of the PYR/PYL/RCAR abscisic acid (ABA) receptors. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
3 It is known that the clade A protein phosphatase 2Cs (PP2Cs), including ABI1 and ABI2 and other PP2C members, are key players that function directly downstream of the PYR/PYL/RCAR abscisic acid (ABA) receptors. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
4 Here, identification of a crucial site for function of ABI2 protein phosphatase in ABA signalling is reported. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
5 Further, genetic evidence was provided to demonstrate that this CPL is required for the function of ABI2 to mediate ABA signalling. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
6 These data reveal that this CPL is an important site necessary for both the phosphatase activity of ABI2 and the functional interaction between ABI2 and PYL5/9 ABA receptors, providing new information to understand primary events of ABA signal transduction. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
