(A) Dendrogram presenting the diversity of the yeast specimens based on seven S. kudriavzevii-specific microsatellite loci. A total of 24 S. kudriavzevii strains isolated from oak trees in Japan, Portugal, or France (Ardèche) are compared to 32 S. kudriavzevii/S. cerevisiae hybrids isolated from wine (green lines) or beer (orange line) from France (red letters), Switzerland (blue-green letters), Germany (pink letters), or Hungary (purple letters). The clusters found for the different S. cerevisiae/S. kudriavzevii hybrids are highlighted by circles. (B) Assignment of the different strains to seven clusters inferred using the Structure software program. Identical clones were removed before the analysis. The names of the strains are shown below the figure, and the isolation sources are listed above the figure.
