[Effect of rad 54 mutation on the ability of Saccharomyces cerevisiae cells to recover from radiation and thermal injury].
The diploid cells of Saccharomyces cerevisiae carrying rad 54 homozygous mutation do not exhibit an ability for any considerable "rapid" postirradiation and post-hyperthermic recovery. A pretreatment with high temperature (50 degrees C) increases the radiation response of mutant cells. Survival of cells overheated before gamma-irradiation is increased by keeping them in water for 2-6 h at 28 degrees C, while the corresponding value of survival for cells treated by each of the factors delivered separately remains constant in these conditions.
