title: Genetic characterization of the new morphological and UV-sensitive mutants in Coprinus cinereus. I. A UV-sensitive mutation rad 1 associated with elevated frequencies of mitotic and meiotic recombination.
abstract: Studies on the effect of an UV-sensitive mutation, rad 1, in meiotic and mitotic recombination in Coprinus indicated that, in homozygous condition, rad 1 increased the spontaneous meiotic recombination by 50% and UV-induced mitotic intergenic recombination by about 5-fold. The homozygous rad 1 diploid was shown to be much more sensitive to the recombinogenic effects of polyfunctional than than of mono- or non-functional alkylating agents.
