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
