About

WG Zeilinger-Migsich

Our research focuses on microbial interactions with a special emphasis on fungal mycoparasites. We investigate molecular details of gene regulation of the interaction partners and signal transduction processes involved in microbial communication and recognition processes. We further investigate fungal secondary metabolite production triggered by biotic and abiotic signals in efficient mycoparasitic biocontrol agents such as T. atroviride.

Projects

From Organismic to Biomolecular Interactions - Visualizing signaling complexes in the fungal membrane. In collaboration with Prof. Gerhard Schütz Biophysics group (Vienna University of Technology) we are analysing single molecule dynamics during mycoparasitic attack.

More Information
TRICHO-TOR – This project explores TOR kinase signaling and its role during the mycoparasitic Trichoderma atroviride –prey fungus interaction.

More Information
CHEM-TALK – Chemical cross-talk in mycoparasitic interaction. This project aims at elucidating the role of chemical cross-talk in triggering metabolite production and in mediating the interaction between two fungi, the mycoparasite Trichoderma atroviride and the plant pathogen Botrytis cinerea
