Phylogenetic relationships among wine yeast strains based on electrophoretic whole-cell protein patterns.
In the present work, a phylogenetic study based on protein electrophoretic profiles of Saccharomyces strains isolated from different Spanish wine regions has been carried out. Qualitative differences between the protein electrophoregrams were found at inter- and intraspecific level, but not between electrophoregrams of strains isolated at the same ecosystem. The numerical analysis of these results allowed us to conclude that intraspecific relationships are determined by ecological factors, as well as human influences (dispersion and artificial selection). A correlation between ecological and/or geographical origin and the relationships among strains was observed.
