—Population structure of Saccharomyces cerevisiae. (a) STRUCTURE plot (run 1) that depicts the analysis of 47 strains from all major populations and from the cachaça lineages that emerged from the phylogeny depicted in figure 1. The plot is based on a subset of 10,445 parsimony informative sites for K = 12. Numbers from 1 to 8 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. (b) STRUCTURE plot (run 2) that depicts the analysis of 61 strains, excluding representatives of less relevant populations as inferred from run 1 and including all cachaça strains. The plot is based on a subset of 10,308 parsimony informative sites for K = 12. Numbers up to 10 represent the different clusters that capture the maximum representation of population ancestry.
