Yeast population structure


Baker's yeast, Saccharomyces cerevisiae, is widely used as a laboratory model system.  We have been studying its nearest wild relatives, S. paradoxus and S. cariocanus, in order to be able to use powerful yeast biotechnology to study natural populations.

Wild yeast grows on the bark and leaves of hardwood trees.
