I don't know if anyone has been successful with the tet repressor yet in
S. cerevisiae, but I would be real interested to find out if anyone
Glucocorticoid and estrogen work quite well as inducible systems in
yeast. I do not know the details of your experiment, but if you simply
want to avoid shifting your cells into galactose media to induce a GAL
promoter, there is a tripartite fusion protein available from Didier
Picard that uses estrogen as a gratuitous inducer. The parts of the
protein are the GAL4 DNA binding domain-ER hormone binding domain-VP16
transactivation domain (Gene. 1993. 131, 129-134.). Thus, you can
turn on GAL1-10 promoters by simply adding estrogen to your cultures
thereby avoiding nasty changes in carbon source.
Good luck with your experiment.
