A multivirulent Plasmopara viticola strain from Cilaos on Reunion Island breaks down Rpv1, Rpv3.1 and Rpv10 mediated resistance of grapevine

Julie Ramírez Martínez, Anne-Sophie Miclot, Etienne Dvorak, Isabelle D. Mazet, Carole Couture, Laurent Delière, Frédéric Fabre, Ignace Hoarau, Olivier Yobrégat, Marie Foulongne‐Oriol, François Delmotte

The paper identifies a Plasmopara viticola strain from Reunion Island that breaks down three grapevine resistance loci, Rpv1, Rpv3.1, and Rpv10, through genomic and pathogenicity analyses.
