To understand how adaptation and demography affect the genetic diversity of P. viticola populations, we have implemented a population genomics approach by resequencing strains. A total of 65 P. viticola strains have been sequenced and the reads mapped on the reference PacBio genome. This approach will allow to address the following issues :

• demographic history of the invasion of P. viticola in Europe

• adaptation to disease-resistant grapevine cultivars
• molecular bases of pathogenicity : virulence and agressivity
• genetic determinism of Mating Types:
