Abstract
The efficiency of electron carriers in thylakoid membranes untreated and exposed to heat 7-day-old barley seedlings was evaluated with PAM fluorescence. Darkness–light transitional states in chloroplasts after heat exposure are studied. Thermoinduced changes in linear and cyclic electron transport chain of chloroplasts are revealed. The activation of NADPH-dependent electron flux after exposure to elevated temperatures is shown. We assumed that ΔрН of thylakoid membranes employed the regulatory role in the distribution of electron flows and the adaptation of the photosynthetic apparatus to stressful effects.
