Mating-type gene switching in saccharomyces cerevisiae

Abstract

The budding yeast Saccharomyces cerevisiae propagates vegetatively either as MAT a or MATa haploids or as MAT a/MATa diploids created by conjugation of the opposite haploid types (Fig. 1). Mating type is determined by two different alleles of the mating-type (MAT) locus.
