| description | Ca<sup>2+</sup> and H<sub>2</sub>O<sub>2</sub> interact with each other to regulate plant systemic responses. However, their precise mechanism is not fully understood. A recent study revealed that the Ca<sup>2+</sup> regulates the glycolate oxidase-catalase (GC) switch-mediated photorespiratory H<sub>2</sub>O<sub>2</sub> during wounding. Glutamate-receptor-like (GLR) Ca<sup>2+</sup> channels (GLR 3.3 and GLR3.6) are responsible for Ca<sup>2+</sup> influx during injury for regulation of the GC switch. Mechanical injury quickly shifts the GC switch to a highly interactive state in the systemic leaves that ultimately results in the reduced peroxisomal H<sub>2</sub>O<sub>2</sub>. However, the mechanism of H<sub>2</sub>O<sub>2</sub> reduction in peroxisome remains elusive. |
