Fig. 3. Partial suppression of the γ-ray sensitivity conferred by the rad57 mutation by rad51-I345T expressed from the chromosome. Survival was assessed following incubation at 30°C. The log percentage survival was plotted as a function of dose for each strain (filled squares, rad51-I345T; open squares, wild-type; filled circles, rad51-I345T rad57::LEU2; open circles, rad57::LEU2; filled triangles, rad51:: LEU2; open triangles, rad51::LEU2 rad57::LEU2).
