RPB (Résistance des Plantes aux Bioagresseurs) is a joint research unit of IRD, CIRAD and the Université de Montpellier 2. RPB contributes to the project Comparative population genomics.

Improving durability of plant resistance results from a wide range of procedures, including agronomical, biological, chemical or genetic controls, used in integrated pest management.  Assessment of resistance durability occurs at three levels: the gene, the genotype and the population. To optimize sustainability, it is of importance to increase our knowledge (i) in diversity of available resistance genes (R), and (ii) in defense mechanisms underlying plant-parasite interactions, including those involved in plant resistance breakdown. The project is aiming at elaborating tools and methods that will allowed the transfer of R genes in cultivated plants.
