DISTRUCT plots of inferred ancestry profiles from vineyard and winery S. cerevisiae populations.

Each column represents an ancestry profile for an individual MLG. Each colour corresponds to a subpopulation/cluster. The scale of each colour in an ancestry profile represents the proportion (membership coefficient) of the individual’s ancestry profile assigned to that cluster, as measured on the y-axis of each plot. The legend indicates the subpopulation/cluster number and colour. An ancestry profile for each commercial and commercial-related MLG in the dataset is noted in the legend. Subpopulations containing commercial MLGs with membership coefficients >80% are labelled with the strain name in parentheses, unique subpopulations with SBV in parentheses.
