Redox Regulation in Plants to Control Photosynthetic Activity

Caption

Reduction/oxidation reactions in plants that control the activity of photosynthetic proteins when light is present (unshaded) and when it is absent (shaded). Unlike the well-known reactions that occur in the light, the mechanism of regulation in the dark was poorly understood. This study demonstrates that energy is funneled from the proteins to TrxL2 to 2CP and finally to hydrogen peroxide, keeping photosynthesis on standby until light is available again.
