Rao BS and Reddy NM (1982) Genetic control of budding-cell resistance in the diploid yeast Saccharomyces cerevisiae exposed to gamma-radiation. Mutat Res 95(2-3):213-24
Abstract: The gamma-radiation response of stationary and budding cells of wild-type diploid strains (RAD) and radiation-sensitive strains rad2, 6, 9, 18, 50-55, 57 and rec4 was studied. As compared with the wild-type strains, mutants generally showed enhanced sensitivity in both stages of the cell cycle. Budding-cell resistance was totally absent from rad50-55 strains. Mutants rad6, 9 and 18 showed some degree of budding-cell resistance. The response of rad2 and rec4 strains was identical with that of the corresponding wild-type strains. These results suggest that the pathway dependent upon the expression of RAD50-55 loci functions more efficiently in budding cells compared with the pathway dependent on RAD2 and RAD6, 9 and 18 loci. Recombination between sister chromatids appears to play an important role in budding-cell resistance, and this process is under the control of the RAD52 repair pathway. The relationship between the repair pathways associated with budding-cell resistance and post-irradiation cellular recovery (LHR) is discussed.
