FIG. 8.

Deletion of SPT4 restores MPA and UV resistance of rad7 rad26 rpb9 cells. (A) Sequential 10-fold serial dilutions of yeast cells were spotted onto SD plates containing different concentrations of MPA. The plates were incubated for 6 days before being photographed. (B) Sequential 10-fold serial dilutions of yeast cells were spotted onto SD plates and irradiated with different doses of 254-nm UV light. The plates were incubated for 4 days before being photographed.
