A schematic diagram of lipid peroxidation and a model showing a pathway of damage to the D1 protein and LHCII which is triggered by lipid peroxidation.

(A) A detailed mechanism for lipid peroxidation and the related processes. (B) A diagram showing proposed pathways for the light-induced damage to the D1 protein and LHCII. (1) a well- known route showing the light-induced production of 1O2 at the reaction center of PSII and damage to the D1 protein. (2) a new pathway of damaging the D1 protein through lipid peroxidation and the subsequent formation of 1O2 and MDA suggested in the present study. (3) lipoxygenase-induced lipid peroxidation and damage to the D1 protein.
