We report the early phase of yeast comparative genomics conducted by a group of seven French CNRS laboratories: the Génolevures Consortium. This first multispecies comparison of Hemiascomycetes (now called Saccharomycotina) opened the way to yeast evolutionary genomics. This analysis indicates that yeasts are powerful organisms to decipher the different mechanisms acting to reshape the genome of eukaryotes during long evolution periods. This initial DNA approach reveals how biodiversity could be characterized with robust data.
