| 1 | The sensitivity of ABI2 to hydrogen peroxide links the abscisic acid-response regulator to redox signalling. | Hydrogen Peroxide | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 2 | Furthermore, the protein phosphatase activity of ABI2 is very sensitive to H2O2, which has recently emerged as a secondary messenger of ABA signalling. | Hydrogen Peroxide | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 3 | Upon H2O2 challenge, ABI2 is rapidly inactivated with an IC50 value of 50 microM in the presence of reduced glutathione. | Hydrogen Peroxide | Protein phosphatase 2C family protein | Arabidopsis thaliana |
| 4 | The levels of the major cellular thiol compounds cysteine and glutathione in leaves and seedlings of A. thaliana are compatible with a physiological role of H2O2 in regulating ABI2 activity. | Hydrogen Peroxide | Protein phosphatase 2C family protein | Arabidopsis thaliana |
