Compilation of PP2C regulation by ABA receptors from Arabidopsis. The figure depicts combined RCAR (R1–R14) regulation of single PP2Cs in the abscence (A) and presence (B) of 10-µM exogenous ABA. The data presented is taken from Fig. 3. Members of the RCAR subfamily I are shown in yellow to red colors, subfamily II members in blue, and subfamily III RCARs in different green shades as indicated. Note that AHG1 is poorly regulated by RCARs. In the presence of exogenous ABA, only three subfamily I members substantially regulate AHG1.
