Noun
dikaryon (plural dikaryons)
(biology) A hypha that has two nuclei.
Occasionally, monokaryons of some taxa can form morphologically fully formed basidiomes and anatomically correct basidia and ballistic basidiospores in the absence of dikaryon formation, diploid nuclei, and meiosis. Source: Internet
The dikaryon is long lasting but ultimately gives rise to either fruitbodies with basidia or directly to basidia without fruitbodies. Source: Internet
Others are secondarily homothallic, in that two compatible nuclei following meiosis migrate into each basidiospore, which is then dispersed as a pre-existing dikaryon. Source: Internet
Plasmogamy between compatible individuals leads to delayed karyogamy leading to establishment of a dikaryon. Source: Internet
