Cell biology of plant pathogenic fungi and disease resistance.
The two projects in my research program make substantial use of freeze-substitution, video enhanced microscopy, computer-assisted structural analyses and molecular genetics. Equipment and software for these advanced techniques are upgraded periodically.
One project deals with cytological aspects of penetration processes and host responses in fungus-incited diseases of fruits. The current emphasis is on mechanisms of induced resistance used for biological control of post-harvest diseases.
The other project addresses various questions in fungal cytology, especially nuclear behavior. We are currently investigating the role of two microtubule-associated motor proteins -- kinesin and dynein -- in the generation of mitotic forces in the ascomycete, Nectria haematococca. This project combines molecular genetics -- to generate and analyze mutants -- with cytology -- to detect and document mitotic phenotypes.
