RESUMO
A convenient assay to score repeat-induced point mutation (RIP) in Neurospora employs the erg-3 locus as a mutagenesis target. Using this assay we screened 132 wild-isolated Neurospora crassa strains for ability to dominantly suppress RIP. RIP was exceptionally inefficient in crosses with the wild isolates Sugartown (P0854) and Adiopodoume-7 (P4305), thereby suggesting the presence of dominant RIP suppressors in these strains. In other experiments, we found no evidence for dominant RIP suppression by the Spore killer haplotypes Sk-2 and Sk-3.
