title: Evidence for nuclear restriction of supersuppressor gene products in Neurospora heterokaryons.
abstract: It was demonstrated that the gene products of the three ssu loci cannot enter the transcription/translation system coded by the other component nucleus in a heterokaryon. In such a situation, dominance or recessiveness cannot be established, and simple dominance tests are meaningless.
