Method for the estimation of effective concentration of polyols in green algal lichens at low temperature.
Original language description
Introduction: Polyols (sugar alcohols) help lichens to maintain physiological activity at sub-zero temperatures. Among them, ribitol synthetised by symbiotic green algae in a lichen thallus represents one of the most important. Ribitol is main high-energy compound exported from a symbiotic producer (alga) to a consumer (fungus) and its natural concentration in a lichen thallus ranges 2-7 µg g-1 DM [1,2]. In fungal hyphae, ribitol is transformed into mannitol, which serves as energy source for maintenance and growth of fungal hyphae as well as production of fungal-specific compounds [3], such as e.g. pigments [4]. Limited number of experiments has been made so far, that focused on cryoprotective effects of ribitol on physiological processes of symbiotic algal cells [e.g. 5]. Here, some preliminary results are presented for two lichen species exposed to 3 stepwise increased concentrations of ribitol. Material and Methods: Thalli of foliose lichen species Umbilicaria hirsuta, Lasall
