Involvement of antioxidants in photoprotection of lichens
Original language description
The aim of this study was to evaluate the effect of high light on antioxidants content in different lichen species. Several lichen species were collected in Norway (Peltigera canina, Lobaria pulmonaria, Lobaria scrobiculara) and in Czech Republic (Hypogymnia physodes, Lasallia pustulata). Lichen thalli were hydrated and exposed to 3 light treatments differing in intensity and length. Contents of photosynthetic pigments (including xanthophylls), glutathione (both oxidized and reduced form) and tocopherolwere analyzed in samples before and after each treatment. Comparison of selected species shows different antioxidants content in relation to different light habitat (light/shade adapted species) and different photobiont (green/blue algae). These results, combined with chlorophyll fluorescence measurements, give better insight in the photoprotection of lichens against excess light.
