Effects of rad9∆ or exo1∆ on the fitness of cdc13-1 strains. Fitness profile showing the effects of ∼5000 yfg∆ library mutations on the fitness of ura3∆, cdc13-1, cdc13-1 rad9∆, and cdc13-1 exo1∆ strains. Each point represents the fitness of one gene deletion strain in each combination of genetic background and temperature. Fitness is measured as in Figure 1. Nineteen telomere-related genes from Figure 1A are highlighted with colored symbols.
