Phylogenetic analysis of P. viticola isolates. NJ tree based on allele shared distance (DAS) calculated with eight microsatellite loci for the three isolates of this study (SU, SC, and SL) and 18 P. viticola isolates collected in Italy (IT), France (FR), Czech-republic (CZ), Germany (DE) and in the United States of America (US). Bootstrap percentages > 50% are reported above the branches of the tree. For French isolates the star (*) indicates isolates collected in Colmar.
