Research interests
UVB resistance mechanisms of algae and plants
All photosynthetic organism need to protect themselves against the harmful effects of ultraviolet-B radiation. Major targets of UVB are the photosynthetic machinery and the DNA. Resistance towards UVB radiation can either be established by effective shielding or by tolerance mechanisms, like repair of induced damages. One important repair mechanism is the light-dependent splitting of UV-B induced DNA dimers, called photoreactivation. My future studies will concentrate on the following:
1. Ulva intestinalis as a model organism of a non-UV screening macroalga:
- Characterisation of photoreactivation rates under controlled experimental conditions
- Analysis of the expression of the photolyase gene under laboratory and field conditions combined with physiological activity measurements
- Investigation of the ultrastructural effects of chloroplasts and nucleus localisation with respect to DNA damage formation and distribution.
- Searching for other factors which contribute
to the DNA stability of Ulva intestinalis by a comparison of the intrinsic sensitivity of the DNA with Arabidopsis thaliana and other plants
2. Cladophora sericea as a model organism for a UV-screening macroalga:
- Characterisation of the screening substance
- Determination of the variability of observed screening depending on abiotic factors under field and laboratory conditions
