Genetic interaction between <i>CDC4</i> and <i>GRR1</i>.

<p>5-fold dilutions of cells with the indicated genotypes were grown at 23°C (the permissive temperature for <i>cdc4-1</i>). All strains are <i>rgt1Δ</i>, which alleviates the glucose repression defect in <i>grr1Δ</i> strains. Note that <i>grr1Δ cdc4-1</i> cells are growing, but at a much slower rate than single mutant strains. Plates are shown at an early time point when wild-type and single mutant strains have not reached saturation, to better illustrate the differences in growth rates among the strains.
