Auto-Summary
The post discusses various aspects of mushroom breeding, including life cycles, interspecific hybridization, protoplast fusion, and mutation. It highlights techniques such as serial dilution, DDK pairing, and protoplast fusion for obtaining monokaryons. The post also covers sexual development, hybrid vigor, and mating type experiments in Psilocybe cubensis. Additionally, it mentions the importance of stabilizing strains through spore selection and the potential for crossing different mushroom strains.

kary-
karya-, karyo-, cary-, carya-, caryo-
A prefix meaning "nucleus." From Gr. karyon.
A Glossary of Mycology 1971, p. 27.
monokaryotic
monocaryotic, primary mycelium
Cells having a single nucleus each; having genetically identical haploid nuclei (monokaryon or haplont). Found, for example, in the mycelium of Agaricales.
Dictionary of the Fungi (8th ed.) 1995, p. 291;
A Glossary of Mycology 1971, p. 103;
Illustrated Dictionary of Mycology 2000, p. 244.
dikaryotic
dicaryotic, secondary mycelium
A single cell (dikaryon) having two genetically distinct haploid nuclei.
A Glossary of Mycology 1971, p. 46;
Dictionary of the Fungi (10th ed.) 2008, p. 209.
plasmogamy
The fusion of two cells or plasmodial cytoplasms, resulting in the nuclei juxtaposed and a dikaryon formed. In many sexual phases of fungi, the first step which precedes karyogamy (nuclear fusion) and meiosis.
Dictionary of the Fungi (10th ed.) 2008, p. 543
Illustrated Dictionary of Mycology 2000, p. 300
karyogamy
caryogamy, nuclear fusion
The final stage in the fusion of two sexual nuclei, after plasmogamy, that forms the zygote nucleus, but before meiosis.
A Glossary of Mycology 1971, p. 27;
Dictionary of the Fungi (10th ed.) 2008, p. 349;
Illustrated Dictionary of Mycology 2000, p. 213.
mitosis
The normal division of a nucleus. Results in two child nuclei with the same number of chromosomes as the parent.
Illustrated Dictionary of Mycology 2000, p. 241.
meisosis
A series of two successive nuclear divisions that reduces the number of chromosomes by one-half, going from a diploid state to a haploid one. The last part of the sexual phase in many fungi, following plasmogamy and karyogamy. Contrast with mitosis.
Illustrated Dictionary of Mycology 2000, p. 233.
