Effects of extrenally added ribitol on primary photosynthetic processes at low and freezing temperature in lichen thalli.
Original language description
In lichens, polyols (sugar alcohols, e.g. ribitol, arabitol, mannitol) have several physiological roles. They are effective carbon storage and anti-freezing substances. Natural levels of polyols in lichens are species-specific and vary within 1.4-8.8 mg.g-1 DW (ribitol), 0.4-29.0 mg.g-1 (mannitol). In our study, we tested positive effects of extrenally added ribitol on primary photosynthetic processes at low/freezing temperature and evaluated interspecific differences between 3 fruticose species (Cetraria islandica, Cetraria nivalis, Cetrariella delisei collected in Southern Norway and single foliose lichen collected in Svalbard. Lichen thalli were exposed to ribitol concentrations of 0 (control), 16, 32, 40, 50 mM for 168 h at 0 deg C and two subzerotemperatures.
