Major Research Interests

Why do secondary metabolites exist in Nature, what biological roles they play? These questions motivate our research. Thousands of new secondary metabolites are being discovered each year by chemists and pharmaceutical companies but hardly anything is known about their functions. Strong and diverse biological activities exerted by secondary metabolites have been attracting extensive applied research. Fungal metabolites toxic to animals, called mycotoxins, threaten the health of consumers and farm animals when ingested with food and feed. Microbial and plant metabolites inhibiting the growth of pathogens or of cancer cells serve as lead structures for drugs and pesticides. Secondary metabolites with antioxidative and chemoprotective activities as well as those contributing to the taste, aroma and color of food are important quality factors of food commodities. Our lab addresses selected fundamental and applied questions related to secondary metabolites with focus on the following topics:
- Chemical interaction of fungi with other fungi, plants and arthropods
- Relationship between genomic and metabolic diversity
- Biological function of plant root exudates
- Enzymatic detoxification of mycotoxins
