Buller phenomenon
WebOf Buller’s many and varied contributions, few had the impact and significance of his discovery that, in the Hymenomycetes, a haploid mycelium could be diploidized by a dikaryotic diploid mycelium. In homage to him, Quintanilha (1939) designated this as the Buller phenomenon. WebJul 1, 2013 · The Buller phenomenon is not a laboratory phenomenon; there is ample evidence from field studies that nuclei in close proximity undergo reassortment (Johannesson and Stenlid, 2004; Kay and Vilgalys, 1992; Nieuwenhuis et al., 2013c; Ullrich, 1977), such that one nucleus has clearly mated with multiple other nuclei. Here I …

The dikaryon cannot incorporate another type of nucleus, but can still act as a nucleus donor in a dikaryon-monokaryon (di-mon) mating, known as the Buller phenomenon.
