  • The growth phenotypes of mediator subunit mutants in a swi6 background grown on YEPD plates were scored from best to worst as follows: ++, +, (+), +/−, −. ND, not determined. The suppression phenotype of each double mutant is indicated as “+” if the mediator defect restores HO-lacZ expression on the basis of the X-Gal filter assay described in materials and methods.
