Botanisches Kolloquium: Terrestrial Green Algae in Polar and Alpine Environments – Adaptations to Desiccation and UV radiation

Prof. Dr. Andreas Holzinger, Institut für Botanik, Universität Innsbruck, Österreich

Life is relying on water. When water gets sparse, cells desiccate and beyond a certain threshold, death is unavoidable. However, there are a few specialists that tolerate desiccation in their vegetative state, making them unique systems to study tolerance mechanisms. In streptophytic green algae, several members live in water - land transition zones. Conjugating green algae are considered closest living relatives to land plants, which have inherited adaptation strategies, not only to desiccation but also to enhanced UV radiation, going along with their aeroterrestrial habitats. The adaptation mechanisms were studied at different levels – physiological, ultrastructural and molecular.
