Adaptation of <i>Globodera pallida</i> to Individual Components Compromises the Durability of Pyramided Resistance in Potato.

ABSTRACT: The use of resistant plants is an effective alternative to chemical products. But their sustainability is often compromised by the rapid adaptation of pathogen populations. For the cyst nematode Globodera pallida, a major parasite of potato, several quantitative trait loci (QTLs) conferring resistance have been identified, but their individual use could lead to resistance breakdown. Combining several resistance loci within a single potato genotype has been proposed as a strategy to improve both efficacy and durability. However, the evolutionary pathways leading to the circumvention of this pyramidal resistance remain unknown. The combination of experimental evolution, phenotyping and genome scan enabled us to study the genomic basis of G. pallida adaptation to individual (
