RADIOSENSITIVITY OF HOMOZYGOTE YEAST CELLS OF VARIOUS PLOIDY TO DENSE IONIZING CORPUSCULAR RADIATION (in German)

· Naturwissenschaften (West Germany)
The inactivation degree was determined for four yeast strains of various ploidy after irradiation with a single dose of He/sup 4/, Po/sup 210/ alpha particles, C/sup 12/, and O/sup 16/. The results showed that for all types of radiation the triploid has the highest resistance, and the tetraploid strain has a higher sensitivity than the diploid strain. The evaluation of the survival rate showed that the increase in sensitivity in the transition from triploid to tetraploid strains reflects the almost sole influence of dominating lethal mutations in these higher ploidy.
