Evolutionary genomics of plant-pathogen interactions

Evolutionary Genetics

Most plants face attacks by fungal pathogens. In agriculture, outbreaks of diseases are frequent and pose a significant threat to sustainable food production. What enables pathogens to overcome host defenses and cause damage is poorly understood. A key evolutionary step for pathogens is to evolve effectors that specifically target and disable the plant immune system.

Our group uses experimental and population genomics tools to analyze the rapid emergence of pathogens. A major focus is to use genome-wide association studies (GWAS) to directly identify the genes in pathogen genomes linked to the breakdown of host resistance. We also assemble complete genomes to analyze mechanisms that generate high degrees of sequence polymorphism. We are particularly interested in the action of transposable elements (selfish elements in the genome) and the evolution of gene regulation. Our group also conducts population genomic studies to analyze the process of adaptive evolution in natural field populations.
