1 The ABA induction of embryogenesis genes is highly inhibited in the presence of a mutated protein phosphatase 2C, encoded by the abi1-1 dominant mutant gene that is known to block ABA responses in Arabidopsis. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
2 The ABA induction of embryogenesis genes is highly inhibited in the presence of a mutated protein phosphatase 2C, encoded by the abi1-1 dominant mutant gene that is known to block ABA responses in Arabidopsis. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
3 Therefore, it appears that ABA induction and suppression follow two separate signal transduction pathways with the former inhibited by ABI1 and the latter modulated by PKABA1. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
