title: Mutation at the am locus of Neurospora crassa.
abstract: Forty-eight new mutations at the am locus of Neurospora crassa have been characterized. Nineteen mutations were induced by UV; of these, eight were missense, two were frameshifts, two were nonsense, three were deletions and four were unidentified. Twenty-nine mutations were induced with nitrous acid; of these, twenty-one were missense, three were frameshifts, one was nonsense, two were deletions and one was genetically unstable.
