Suppression of hyperinvasive growth mutant phenotypes by glucose. Equal concentrations of cells were grown for 16 h on SCD or SC medium. A 5-μl spot of 1 M glucose was placed onto a filter at the center of SC medium to allow observation of both yf and ff cell types. The RAS2V19 allele was compared on YP and YPD medium because the invasive growth phenotype was more apparent on rich medium. All pictures were at the same scale, with the bar in the lower left-hand corner representing 40 μm.
