—Population structure of S. cerevisiae. STRUCTURE plot based on a subset of 9,860 parsimony informative sites for K = 10. Numbers from 1 to 10 represent the different clusters that capture the maximum representation of population ancestry. The phylogenetic groups inferred in figure 1 are “color-coded” at the bottom of the plot. Migrant strains are marked with “colored diamonds”: “red” (isolated in Brazil), “green” (isolated in Europe), and “blue” (isolated in North America). “Yellow circles” depict non-Brazilian strains with partial Brazilian ancestry.
