Linde Group - Population genetics, evolution, phylogeography and molecular phylogenetics of fungi

Our main research interest is in fungal-plant-interactions. Our work includes both applied and pure research on a range of important pathogens including barley scald, barley net blotch, Ascochyta on chickpea, Phytophthora etc. We study evolutionary aspects of plant-pathogen-interactions, often utilising population genetic tools to investigate pathogen biology. We are also investigating the mycorrhizal-plant interactions, mycorrhizal fungi species diversity, population diversity and host specificity of orchid mycorrhizae. Speciation processes in orchids are facilitated by specific pollinator interactions, and possibly mycorrhizal interactions. We are using sexually deceptive orchids to study these interactions.
