摘      要：Plants often encounter light intensities exceeding the capacity of photosynthesis(excessive light)mainly due to biotic and abiotic factors,which lower C02 fixation and reduce light energy *** excessive light,the photosynthetic electron transport chain generates damaging molecules,hence leading to photooxidative stress and eventually to cell *** this review,we summarize the mechanisms linking the excessive absorption of light energy in chloroplasts to programmed cell death in plant *** highlight the importance of reactive carbonyl species generated by lipid photooxidation,their detoxification,and the integrating role of the endoplasmic reticulum in the adoption of phototolerance or cell-death ***,we invite the scientific community to standardize the conditions of excessive light treatments.
