The natural ecology of Saccharomyces yeasts

The extensive existing knowledge about S. cerevisiae based on studies in the lab or in human-made fermentations is unrivaled. Surprisingly almost nothing is known about the natural ecology of the yeast. Wild Saccharomyces are referred as being associated with oak trees especially the bark, which seems...

Heterosis in yeast hybrids

We are particularly interested in the performance of the first hybrid generation (F1 hybrids), especially when hybrids are viable and able to outperform one or both parents under different environmental conditions, a phenomenon known as heterosis. The aim of our work was to understand mechanisms underlying...
