  • Discussing the physiology, biochemistry, and molecular biology of interactions between phytopathogenic organisms and their plant hosts
  • Understanding the biology of host-parasite-relationships on the levels of physiology, biochemistry, and molecular biology
  • Identification of molecular targets in order to control phytopathogenic organisms

Mail Topics

  • Mechanisms of resistance
  • Factors of virulence and pathogenity
  • Specifics of hosts
  • Molecular cytology


Combining different methods in researching host-parasite-interactions has led to significant progress in recent years. Numerous virulence factors and first pathogenic factors of fungi and bacteria have been characterized, and mechanisms used by plants to detect pathogens have been identified. Various targeted defensive reactions that can be activated deliberately by plants, are known by now. With the help of transgenic plants it is not only possible to study the function of particular defense substances, but also to implement new resistance mechanisms into plants. Such strategies can become essential components of modern plant protection.
