The linkage of two mutations leading to increased sensitivity to ultraviolet light and 60Co gamma rays was determined in the slime mould Dictyostelium discoideum using a genetic analysis based on the parasexual cycle. Diploids were selected from a mixture of radiation-sensitive, temperature-resistant and radiation-resistant, temperature-sensitive haploids(More)
An assay based on forward mutation of Dictyostelium discoideum to 3% methanol resistance allows quantitation of induced mutation following treatment with physical and chemical agents. Properties of this assay are: uniform recovery of methanol-resistant (MeOHr) cells over a wide range of plated cell densities, equal growth rates of methanol-sensitive and(More)
