Oxygen-induced genetic changes in dry yeast cells.
Cells of Saccharomyces cerevisiae were dried in vacuum, exposed to oxygen, nitrogen, air, and water vapor, and rehydrated with degassed medium without exposure to air. Drying per se caused few genetic changes, but the exposure of dry cells to oxygen increased the frequency of adenine-requiring colonies.
