Genetic effects of ozone: induction of point mutation and genetic recombination in Saccharomyces cerevisiae.
The mutagenicity and recombinogenicity of the atmospheric pollutant, ozone, were investigated in several strains of Saccharomyces cerevisiae. It was observed that ozone induced a variety of genetic events, such as forward and reverse mutations as well as gene conversion and mitotic crossing-over. However, when compared to known mutagens like ultraviolet light, X-rays and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), ozone appeared to be a weak mutagen.
