Deletion of MUS81 exacerbates defects in rmi1-1 mutants. The indicated strains were released from G₁ arrest at 35°C into medium containing 0.0167% MMS for 1.5 h and then resuspended in drug-free medium as described for Fig. 2C. Samples were taken following α-factor arrest (α), after 1.5 h exposure to 0.0167% MMS (+ M), after 2 h of recovery from MMS treatment (2), and after 4 h of recovery (4). The samples were analyzed by PFGE.
