title: Genetic analysis of ad-3 mutants induced by AF-2 and two other nitrofurans in Neurospora crassa.
abstract: Our previous studies have shown that the nitrofurans AF-2, SQ18506, and FANFT are potent mutagens in Neurospora crassa. The genetic damage produced by these chemicals at the ad-3 region in N crassa has been characterized by a series of genetic tests. The results of these tests indicate that all three agents induce a high frequency of point mutations and probably a low frequency of multilocus deletions. A comparison of the complementation patterns among the AF-2--induced ad-3B mutants and those induced by other chemical agents indicates that the spectra of intragenic alterations induced by AF-2 in N crassa are similar to those induced by monofunctional alkylating agents.
