Sequencing of a natural Saccharomyces cerevisiae x Saccharomyces uvarum hybrid

An unknown interspecies Saccharomyces hybrid, 'Muri', was recently isolated from a 'kveik' culture, i.e. a traditional Norwegian farmhouse brewing yeast culture (Preiss et al., 2017). Here we used whole genome sequencing to reveal the strain as an allodiploid Saccharomyces cerevisiae × Saccharomyces uvarum hybrid.
