1 The Arabidopsis ABSCISIC ACID-INSENSITIVE2 (ABI2) and ABI1 genes encode homologous protein phosphatases 2C involved in abscisic acid signal transduction. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
2 In Arabidopsis, the ABA-INSENSITIVE1 (ABI1) protein phosphatase 2C is required for proper ABA responsiveness both in seeds and in vegetative tissues. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
3 Thus, the homologous ABI1 and ABI2 phosphatases appear to assume partially redundant functions in ABA signaling, which may provide a mechanism to maintain informational homeostasis. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
