CR effects on silencing of a MET15 reporter integrated into the NTS2 region of an rDNA repeat. The indicated strains were streaked for single colonies onto 0.5xYPD plates containing 0.1% lead nitrate and either 2%, 0.5%, or 0.2% glucose. Darker colony color indicates better rDNA silencing of MET15. Colonies were grown for 5 days.
