Emerging virulence arising from hybridisation facilitated by multiple introductions of the sunflower downy mildew pathogen Plasmopara halstedii.

Fungal genetics and biology : FG & B - 1 Oct 2012

Abstract excerpt

The sunflower downy mildew pathogen Plasmopara halstedii is an invasive plant pathogen in Europe of American origin. Despite efforts to produce resistant host varieties, nationwide monitoring in France has revealed the rapid emergence of new virulent races increasing the number from one founder identified in 1966 to as many as 14 today. We have genotyped 146 samples (including all 14 races) using 13 nuclear and...
