Photocontrol of Anthocyanin Synthesis: V. Further Evidence against the Involvement of Photosynthesis in High Irradiance Reaction Anthocyanin Synthesis of Young Seedlings.

abstract：:Plants, algae, and cyanobacteria have developed mechanisms to decrease the energy arriving at reaction centers to protect themselves from high irradiance. In cyanobacteria, the photoactive Orange Carotenoid Protein (OCP) and the Fluorescence Recovery Protein are essential elements in this mechanism. Absorption of stro...
