| 1 | The ABI1 and ABI2 protein phosphatases 2C act in a negative feedback regulatory loop of the abscisic acid signalling pathway. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 2 | These genes have been originally identified by the dominant mutations abi1--1 and abi2--1, which reduce the plant"s responsiveness to the hormone abscisic acid (ABA). | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 3 | These genes have been originally identified by the dominant mutations abi1--1 and abi2--1, which reduce the plant"s responsiveness to the hormone abscisic acid (ABA). | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 4 | Abi2--1R1 plants displayed a wild-type ABA sensitivity. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 5 | However, doubly mutant plants combining the abi2--1R1 allele and a loss-of-function allele at the ABI1 locus were more responsive to ABA than each of the parental single mutants. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 6 | These data indicate that the wild-type ABI2 phosphatase is a negative regulator of ABA signalling, and that the ABI1 and ABI2 phosphatases have overlapping roles in controlling ABA action. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 7 | These data indicate that the wild-type ABI2 phosphatase is a negative regulator of ABA signalling, and that the ABI1 and ABI2 phosphatases have overlapping roles in controlling ABA action. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 8 | Measurements of PP2C activity in plant extracts showed that the phosphatase activity of ABI1 and ABI2 increases in response to ABA. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 9 | These results suggest that ABI1 and ABI2 act in a negative feedback regulatory loop of the ABA signalling pathway. | Abscisic Acid | Protein phosphatase 2C family protein | Arabidopsis thaliana |
