Description:<\/span><\/td>\nThe galactose regulon has been utilized for many decades to control gene expression with GAL1pr<\/em> potentially being the most widely used inducible promoter in budding yeast1,2,3<\/sup>. GAL1pr<\/em> is tightly repressed in the presence of glucose by the Gal80 and Mig1 repressors4<\/sup>. In the presence of galactose, GAL1pr<\/em> is induced more than 1000-fold5<\/sup>. Glucose repression induces transcriptional downregulation of GAL<\/em> regulatory genes. To avoid delays when switching from glucose to galactose, cells are typically grown in non-inducing and non-repressing raffinose medium.\u00a0<\/span><\/td>\n<\/tr>\n
