AN X-RAY INDUCED BLOCK PREVENTING CELL DEGENERATION AND ACCOMPANYING AN INHIBITION OF CELL DIVISION IN YEAST
Growing yeast cells given a low dose of x radiation adequate to inhibit cell division were found after a period of starvation to be more viable and also more capable of taking up P/sup 32/ and oxygen and producing carbon dioxide than were unirradiated cells. The possibility was discussed that the action of radiation was somehow to stabilize the cell membrane or a component structure and thus preserve these capacities through the period of starvation, as well as prevent a loss of phosphorus and nitrogen compounds such as occurred from unirradiated cells. The starvation responses occurred in young cells, but not in old cells. In addition, a reduced potassium retentivity and rate of endogenous respiration were observed immediately after irradiation.
