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

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.

A rapid and accurate PCR-based method for mating-type determination in the heterothallic oomycete Plasmopara viticola, the causal agent of grapevine downy mildew

This paper develops two PCR-based markers to rapidly determine mating types in Plasmopara viticola, showing perfect concordance with crossing assays on 37 strains.

Multiple geographic breakdown events of the Rpv1/Rpv3.1 pyramided resistance in grapevine by Plasmopara viticola.

The paper reports the breakdown of Rpv1 and Rpv3.1 resistance in grapevine due to virulent Plasmopara viticola isolates overcoming both resistance genes in multiple vineyards.

Recombination landscape and karyotypic variations revealed by linkage mapping in the grapevine downy mildew pathogen Plasmopara viticola

The paper constructs high-density linkage maps for Plasmopara viticola to study recombination patterns and karyotypic variations, revealing gene-rich regions with higher recombination rates and anomalies in 5% of offspring.

A high-quality grapevine downy mildew genome assembly reveals rapidly evolving and lineage-specific putative host adaptation genes

The paper presents a high-quality genome assembly of Plasmopara viticola, identifying genes under positive selection that may contribute to host adaptation.
