N2 - The influence of increased copper and cadmium concentrations on membrane lipid peroxidation and photosynthetic characteristics of the lichen photobiont Trebouxia erici was assessed. Intracellular copper and cadmium uptake increased due to increased metal availability in the 5 mM HEPES buffer for 24 h. Assimilation pigments, chlorophyll a fluorescence, malondialdehyde (MDA) content and photosynthetic oxygen evolution rate (OER) were sensitive to the presence of redox-reactive metal Cu2+ in short-term experiments. Cd2+ decreased FV/FM values indicating damage to PSII and decrease of OER. However, assimilation pigments and MDA content were not altered significantly.
