The paper monitors 199 plots of disease-resistant grapevine varieties over 8 years, showing reduced fungicide use with maintained disease control, but also resistance decline and emerging black rot issues.

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.

This study identifies genetic factors driving virulence in the grapevine downy mildew pathogen through QTL mapping and population structure analysis, revealing both parallel adaptation and admixture as evolutionary mechanisms.

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.

This study quantifies Plasmopara viticola oospore concentration in vineyard soil using ddPCR and reveals spatial patterns, showing higher oospore accumulation below vine stocks.

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.

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