Yng1p toxicity is rescued by loss of the COMPASS histone methyltransferase complex. Tenfold serial dilutions of yeast strains YLH101, YLH211, and YLH209 (A) and YLH101, YLH206, YLH220, YLH203, YLH204, YLH298, and YLH205 (B) containing the indicated plasmids were plated on synthetic complete medium lacking uracil containing either dextrose or galactose as a carbon source and incubated at 30°C for 3 days.
