Research laboratories

Our group is conducting research on the biology and ecology of tree-associated microorganisms in forest ecosystems.
Our group seeks to explore and understand the network of genes, proteins, metabolites, and environmental signals that lead to the complex ectomycorrhizal symbiosis in forest trees. We are also investigating the molecular interactions between foliar rust and poplar. Interactions between rhizospheric bacteria and ectomycorrhizal mycelium are studied to assess the mechanisms involved and their role in nutrient cycling in forest ecosystems (e.g. mineral weathering). Several research projects are dealing with the ecology of populations and communities of ectomycorrhizal fungi.

Our research initiative aimed to decipher the complex tree-fungus-bacteria systems engages disciplines across the laboratory. In particular, it draws on programs in comparative and functional genomics, biochemistry, bioinformatics and ecology.

Our approach relies upon the most recent genomics and metagenomics techniques and focuses on black cottonwood, Populus trichocarpa, the ectomycorrhizal basidiomycete Laccaria bicolor, and the rhizospheric bacterium Pseudomonas fluorescens as the reference organisms. Harnessing the capabilities of microbial systems by understanding interactions at genomic, physiological, organism, and community levels will lead to better sustainable forest ecosystems.
