Interaction of Ionizing and Visible Radiation in Mutation Induction in Neurospora crassa
Conidia of the purple adenineless strain of N. crassa were irradiated with 25 kr of x rays and then exposed to far-red or red radiations or to far-red followed by red radiation. Far-red light, without effect on unirradiated conidia, augmented the genetic damage caused by x rays as measured by survival (colony count), back mutation to adenine prototrophy, and the induction of mutants affecting colony morphology. Post-x-irradiation with red light ameliorated the severity of x radiation as measured by survival and back mutation. The potentiation of x-ray-induced genetic damage by far-red light could be completely negated by subsequent exposure to red light.
