New preprint from the lab: we show that the ability to switch mating type was lost at least 13 times independently in the evolution of S. cerevisiae. At least 27% of isolates are heterothallic with a strong association with polyploidy and heterozygosity

Repeated losses of self-fertility shaped heterozygosity and polyploidy in yeast evolution
Evolutionary transitions in mating strategy have profound consequences for genetic variation and adaptation. In Saccharomyces cerevisiae, mating-type switching is a central feature of the life cycle t...

Where is Saccharomyces chiloensis??? Now we want to know its exact distribution in the Patagonian coast line. So, back in the Forest 🌳🌿 & looking for it 🔎. Thanks @pablo-villa.bsky.social & Nina Vitorelli for helping out!
