TL;DR: Far from the hypothesis that mtDNA variation is neutral, this work shows that mitochondrial polymorphism can have a strong impact on fitness components and hence on the evolutionary fate of the yeast populations, while respiratory environments may increase the probability to fix Sc-mtDNA.

TL;DR: It is found that hybridization could generate multi-trait phenotypes with improved oenological performances and better homeostasis with respect to temperature, which could explain why interspecific hybridization is so common in natural and domesticated yeast, and open the way to applications for wine-making.

TL;DR: It is shown that the proportion of heterotic proteins was highly variable depending on the parental strain and on the temperature considered, and this proportion was higher at nonoptimal temperature for intraspecific hybrids than for interspecific hybrids.

TL;DR: The fermentation proteome was found to be shaped by human selection, through the differential targeting of a few isoforms for each food-processing origin of strains, and the importance of post-translational modifications in the diversity of metabolic and life-history traits is highlighted.
