11. On the mechanism and consequences of light-induced D₁ protein degradation in higher plants
Abstract : The basic source of energy for the whole biosphere is sunlight which is converted tochemical energy by the process of photosynthesis in a wide variety of organisms rangingfrom prokaryotic bacteria to eukaryotic higher plants. It is therefore surprising thatphotosynthetic activity can be reduced when plants are exposed to excessive light,especially under adverse environmental conditions. READ MORE

12. Reaction-Diffusion kinetics of Protein DNA Interactions
Abstract : Transcription factors need to rapidly find one specific binding site among millions of nonspecific sites on the chromosomal DNA. In this thesis I use various aspects of reaction-diffusion theory to investigate the interaction between proteins and DNA and to explain the searching, finding and binding to specific operator sites.

13. Role of cyclin D1 as an estrogen receptor cofactor and the influence of hypoxia on estrogen receptor regulation, with focus on prognositic and treatment predictive features in breast cancer
Abstract : Estrogen receptor (ER) status can define breast cancer patients who would benefit from adjuvant tamoxifen therapy. However, resistance to tamoxifen is often observed and possible mechanisms may be loss or reduction of ER, dysfunctional ER- signaling and ligand independent activation of the receptor. READ MORE

14. Directed mutagenesis and structure-function analyses of the psbA gene products, D1 and D1', in the cyanobacterium Synechosystis 6803
Abstract : Photosynthesis is the process by which the two essential requirements for man's survival on earth, food and oxygen, are produced. Oxygenic photosynthetic organisms, like plants, algae and the prokaryotic cyanobacteria, harness and convert the sunlight in specialized membranes called thylakoids. READ MORE

15. Regulatory Functions of Protein Phosphorylation in Plant Photosynthetic Membranes
Abstract : Oxygenic photosynthesis is the process in plants, algae and cyanobacteria which converts light energy from the sun into carbohydrates and at the same time produces oxygen from water. Both carbohydrates and oxygen are essential to sustain life on earth. READ MORE
