Molecular Plant Physiology

Nitrogen is one of the most limiting nutritional factors for plant growth and productivity. Therefore diverse and complex strategies have evolved for the uptake, assimilation and reallocation of nitrogen. Our research focuses on the role of plant transporters involved in the uptake as well as the intra- and intercellular distribution of organic nitrogen. We aim at exploring the biochemical properties of these transporters, their regulation and contribution to plant productivity and yield. 

Furthermore, amino acid transport in parasitic protozoa and its role for parasite development and pathogenicity is being investigated.
