Genetic control of plant diseases often relies on major-effect resistance genes. However, they are frequently impaired by pathogen’s adaptation, leading to resistance breakdowns. Plant quantitative resistance and tolerance are assumed to be more durable than major-effect resistance genes but experimental evidence is still scarce.

To explore the potential of these genetic resources, our goal is to measure the capacity of adaptation of plant viruses to plant quantitative resistance and tolerance, using the well-studied pathosystem pepper (Capsicum annuum) - Potato virus Y (PVY; family Potyviridae) as well as the understudied pathosystem pepper – Phytophthora capsici (Oomycete). First, we genotyped a doubled-haploid progeny and a core-collection of pepper using gene capture. These data will allow us to perform QTL mapping and genome-wide association to identify quantitative resistance and tolerance QTLs. Then, we implement different experimental approaches (experimental evolution in both pathosystems, gene and mutation mapping in virus biparental progenies or by genome-wide association) to identify the genes and mutations in virus genomes that are involved in their adaptation to plant quantitative resistance and tolerance.

Beyond genetic control of diseases, the project will unravel the genetic architecture of virus quantitative pathogenicity traits in interaction with plant resistance and tolerance genes, in order to better understand virus evolution and emergence.
