    Description

    The breakdown of host resistance to plant pathogens is of critical concern in agriculture, forestry, and the management of natural systems. Evolution of the fungal poplar rust pathogen Melampsora larici-populina has been shown to have been dramatically influenced by the deployment of resistance genes in commercial poplar (Populus spp.) plantations, with pathogen populations inundated by virulent genotypes (Xhaard et al. 2011). The deployment and subsequent breakdown of resistance genes in poplar plantations provide an experimental system for understanding the dynamics of pathogen evolution in response to resistance breeding, which will be critical to formulating effective management strategies in the future.
