281 J . gen. Microbial. (1963), 30, 281-287 Printed in Great Britain Dose-Mutation Relationships in Ultraviolet -Induced Reversion from Auxotrophy in Escherichia coli BY RUTH F. HILL Radiological Research Laboratory, Department of Radiology, Columbia University, New York, U.S.A. (Received 1 June 1962) SUMMARY Curves for the absolute yield of revertants as a function of ultraviolet (uv) radiation dose were obtained after post-irradiation incubation in saline and after exposure to reactivating light. The curves exhibited plateau regions and final slopes which were equal to the slopes of the survival curves for the auxotrophic Escherichia coli parent. These features may be due to a saturation of the mutagenic effect at low doses. This saturation would be the result of ( a ) heterogeneity in the unirradiated population with respect to the amount of protein and RNA synthesis which can occur before DNA replicates in the irradiated organisms, combined with (b) limitation of the observable yield by the selection method. The ob- servable yield would be derived from the fraction of the population most resistant to the lethal effect of radiation. INTRODUCTION The mechanism by which ultraviolet ( u.v.) radiation produces mutations to prototrophy in amino acid-requiring strains of bacteria has been the subject of many recent investigations (Witkin, 1958, 1961 ; Lieb, 1960; Weatherwax & Land- man, 1960; Doudney & Haas, 1958, 1960a, b; Haas & Doudney, 1959; Doudney, 1961).
