Vitamin metabolism and its relations to environmental stress

Plant Biochemistry and Physiology

Our research focuses on plant metabolism, in particular the biochemistry and physiology behind vitamin biosynthesis and degradation and how these processes interact with other aspects of general primary plant metabolism. We also address aspects of stress physiology and how alteration of vitamin metabolism affects the response to abiotic stress responses. We use bacteria, yeast and the model plant Arabidopsis thaliana and a range of multi-disciplinary biological and chemical techniques as part of our research program.
