Complex ancestries of wild and brewing yeasts
The phylogeography of Saccharomyces eubayanus and its lager-brewing hybrids is shown to be complex by whole genome sequencing. Here we describe two highly diverse populations in Patagonia, as well as a low-diversity Holarctic subpopulation that extends from Asia to North America and is the closest known lineage to European lager-brewing hybrids. Despite a strong domestication bottleneck, some diversity is retained among lager yeasts. This complexity is represented by the phylogenetic supernetwork superimposed on a mug of lager beer in front of an oak tree, one of several known habitats. See Peris and Langdon et al.
