Fields of Research

1. Biology of plant/fungus interaction - with special emphasis on biotrophic parasitic fungi

Plant parasitic fungi affect agricultural crops as well as wild plants and cause severe biomass losses. With regard to their lifestyles one can distinguish between necrotrophs which colonize the host tissue by immediately killing the cells - and biotrophs which are growing on living host tissue only. Fungi of the latter group obtain their nutrients from plant cells and represent a sink within the tissue of their host plants. Nutrient availability of biotrophic plant pathogenic fungi marks an important environmental change from the penetration phase of the fungi to their parasitic phase within the plant tissue. A few days later another major nutritional change occurs: the switch to the sporulation phase, during which the fungi synthesize storage substances of the spores. We are currently working on the following question. How do biotrophic plant parasitic fungi and plants interact at physiological and nutritional level?

2. Development of molecular based diagnostic tools of fungal plant pathogens

To improve disease management and control plant diseases effectively requires infomation about which diseases are present, and how much. Molecular markers can improve disease diagnosis by enabling fast and accurate identification of harmful fungi before disease symptoms develop. Our aim is the development and use of molecular based diagnostic tools of fungal plant pathogens with special emphasis on soil-borne fungi.
Research topics in detail:

  • Influence of rust infection on the nitrogen metabolism of Medicago truncatula
    Rust infected plants loose large amounts of nutrients by feeding the pathogen. In time course experiments we study the regulation of expression of M. truncatula N-metabolite transporter genes and genes of ammonium-assimilating enzymes after inoculation with Uromyces striatus.
  • Resistance of Medicago truncatula against the rust fungus U. striatus
    After Screening 120 cultivars and lines of natural populations of M. truncatula ( kindly provided by J.M. Prosperi, INRA, Montpellier) for reaction to U. striatus infection we have characterized different reaction types ranging from susceptible to highly resistance at the histological level (Kemen et al., Phytopatholgy 95, 153-157, 2005). The aim now is to genetically characterize resistance genes in M. truncatula to use these genes in economically important legumes.
  • In collaboration with Leonor Guerra-Guimarães and Helena Azinheira, Instituto de Investigação Científica Tropical, Oeiras, Portugal: Defense reactions of coffee (Coffea arabica) to the coffee leaf rust Hemileia vastatrix.
  • Development of a PCR-based detection of soil-borne plant pathogens using the fungal rDNA
    Sequences of the rDNA ITS (internal transcribed spacer) are useful in comparing species or populations. Analysis of these sequences represents a basis for disease diagnosis. The aim of the current work is the design of PCR primers from the ITS sequences that allow the identification of different soil-borne pathogens of legumes by PCR amplification.
