Physiological and Genetic Implications of Selective Mutation by Light at 320–400 nm

Nature volume 224, pages 1123–1125 (1969)Cite this article

Abstract

WAVELENGTHS of light between 320 and 400 nm are lethal to many microorganisms1, especially to airborne cells held in a semi-dehydrated state2–4. In addition, this waveband of light produces a few drug5 and phage6 resistant cells when growing cultures are continuously irradiated, and its mutagenic action is enhanced by cell semi-dehydration in aerosols3,4. We report here results which suggest that the irradiation of semi-dehydrated airborne cells with 320–400 nm light produces specific mutations.
