Description Tolerance mechanisms in lichen photobionts to presence of heavy metals were studied in our laboratories. Growth rates, photosynthesis, pigment content, mineral uptake, membrane integrity, dehydrogenase activity, photosystem II activity, free proline synthesis, thiobarbituric acid reactive substances (TEARS), secondary metabolites of lichens, stress proteins and phytochelatins were all markers for assessment of sensitivity, or tolerance of lichen photobionts to heavy metals.
