The efficacy of disease resistance genes in plants decreases over time because of the selection of virulent pathogen genotypes. A key goal of crop protection programs is to increase the durability of the resistance conferred by these genes. The spatial and temporal deployment of plant disease resistance genes is considered to be a major factor...

The evolution of resistance to pesticides and drugs by pests and pathogens is a textbook example of adaptation to environmental changes and a major issue in both public health and agronomy. Surprisingly, there is little consensus on how to combine selection pressures (i.e., molecules used in the treatment of pests or pathogens) over space and...

Réseau de Réflexion et de Recherche sur la Résistance aux Pesticides (R4P) : www.r4p-inra.frCe site met à disposition des outils et des informations sur la résistance aux produits de protection des plantes. Ces informations peuvent intéresser les professionnels impliqués dans la prévention et la gestion des résistances, des enseignants ou...

Understanding the causes of population subdivision is of fundamental importance, as studying barriers to gene flow between populations may reveal key aspects of the process of adaptive divergence and, for pathogens, may help forecasting disease emergence and implementing sound management strategies. Here, we investigated population subdivision...
