Abstract excerpt

Horizontal gene transfer is the movement of genetic material across species. In Saccharomyces cerevisiae, a DNA segment known as Region B was acquired horizontally from a distant yeast species. This region (∼17 Kb) encodes five genes and is present in the genomes of yeast strains from different phylogenetic clades. Interestingly, the presence of Region B is not restricted to yeast strains isolated from...
