Physiological life history strategies of photobionts of lichen species from Antarctic and moderate European habitats in response to stressful conditions

Autor: Nadine Determeyer-Wiedmann, Sieglinde Ott, Andres Sadowsky, Peter Convey

Publikováno v: Polar Biology. 42:395-405

The vegetation of many terrestrial habitats across Antarctica is dominated by poikilohydric symbiotic lichens. Terrestrial habitats generally are characterised by extended exposure to desiccation and high irradiation. Physiological adaptation mechani

Publikováno v: Analytical Chemistry. 89:12006-12013

Polyphosphates have occurred in living cells early in evolution and microalgae contain these important polymers in their cells. Progress in research of polyphosphate metabolism of these ecologically as well as biotechnologically important microorgani

Metabolic response to desiccation stress in strains of green algal photobionts (Trebouxia) from two Antarctic lichens of southern habitats

Autor: Sieglinde Ott, Tabea Mettler-Altmann, Andres Sadowsky

Publikováno v: Phycologia. 55:703-714

Desiccation tolerance is a feature of most lichens. These symbiotic associations of a fungal partner (mycobiont) and a photosynthetic partner (photobiont) experience severe desiccation on a regular basis. Many lichen species colonise extreme habitats

Symbiosis as a successful strategy in continental Antarctica: performance and protection of Trebouxia photosystem II in relation to lichen pigmentation

Autor: Sieglinde Ott, Andres Sadowsky

Publikováno v: Polar Biology. 39:139-151

Lichens as symbiotic associations consisting of a fungus (the mycobiont) and a photosynthetic partner (the photobiont) dominate the terrestrial vegetation of continental Antarctica. The photobiont provides carbon nutrition for the fungus. Therefore,

Effects of UVC254 nm on the photosynthetic activity of photobionts from the astrobiologically relevant lichens Buellia frigida and Circinaria gyrosa

Autor: Andres Sadowsky, F. J. Sánchez, Theresa Backhaus, Sieglinde Ott, R. de la Torre, M. Mrkalj, J. Meeßen

Publikováno v: International Journal of Astrobiology. 13:340-352

In the past decade, various astrobiological studies on different lichen species investigated the impairment of viability and photosynthetic activity by exposure to simulated or real space parameters (as vacuum, polychromatic ultraviolet (UV)-radiatio

Autor: Gerda Horneck, J. Meeßen, Andres Sadowsky, Carlos Vílchez, M.ª del Carmen Ruiz, Rosa de la Torre, F. J. Sánchez, Leopoldo G. Sancho, Sieglinde Ott

Publikováno v: International Journal of Astrobiology. 13:1-18

Many experiments were carried out in order to evaluate the survival capacity of extremotolerant lichens when facing harsh conditions, including those of outer space or of simulated Martian environment. For further progress, a deeper study on the phys

Extremotolerance and resistance of lichens: Comparative studies on five species used in astrobiological research - II. Secondary lichen compounds

Autor: R. de la Torre, F. J. Sánchez, J. Meeßen, Andres Sadowsky, J. P. de Vera, Sieglinde Ott

Lichens, which are symbioses of a fungus and one or two photoautotrophs, frequently tolerate extreme environmental conditions. This makes them valuable model systems in astrobiological research to fathom the limits and limitations of eukaryotic symbi
