[Co60 gamma-ray sensitivity of a series of strains of Saccharomyces cerevisiae yeasts bearing different mutations. I. Radiosensitivity of haploid strains].
Sensitivity to gamma-rays Co60 of haploid strains of Saccharomyces cerevisiae carrying ade1-6 mutations and dominant, semidoninant and recessive suppressors was investigated. It was shown that 3 out of 4 studied strains with ade1-6 mutation had reliable increased radioresistance. The increased radioresistance was observed also in strains carrying, beside ade1-6 mutation, dominant and semidominant suppressors. However the strain carrying a recessive suppressive mutation turned to be radiosensitive. A conclusion is drawn that rediosensitivity of yeast cells can be influenced by different mutations affecting the process of cell metabolism.
