Abstract
Leaves of 10‐ to 12‐day‐old chlorescence lethal Pisum sativum L. mutant are similar to control plants with respect to the content of chlorophylls, carotenoids, fatty acids and α‐tocopherol. Subsequent development of the mutant under high irradiation resulted in th destruction of the photosynthetic pigments, polyunsaturated fatty acids, α‐tocopherol, and also in the accumulation of liposoluble fluorescent products. No increase in the level of malondialdehyde was observed. In chloroplasts isolated from mutant plants the contents of chlorophyll a and β‐carotene were decreased to a greater extent than the more oxidized pigments (xanthophylls and chlorophyll b ). The data obtained are discussed with special reference to the role of lipid peroxidation in the injury of plant cells under the action of visible light and to the antioxidative mechanisms stabilizing photosynthetic membranes.
