The aim is to enlarge recent knowledge on ecophysiology of lichens under extreme conditions, mainly at high and low temperature, different thallus hydration and high light. The project is focused on the analysis of photo protective mechanisms activatedin lichen thalli under high light. Those mechanism related to (1) hyphal cortex layer and exclusively to (2) photobiont will be studied separately. Measurements of changes in spectral reflectance with ongoing thalli dessication and determination ofamount and role of pigments and fungi secondary metabolits will be done. Photo protective mechanism related to photobiont will be studied using fluorometric and biochemical methods. We consider application of several fluorometric methods combined withevaluation of the amount of xanthophyll cycle pigments and antioxidants (glutathione reductase, superoxid dismutase) during high light stress induced under laboratory conditions.
