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.

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.

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.

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.

Streaking methods
Muad.Dweeb said:
Here are some of the streaking methods I've used.

Green = First streak
Blue = Second
Red = Third
Purple = Fourth

This is a classic technique for isolating single cell colonies from yeast and bacteria:



This one I learned from a guy named Sidnee. The green is applied to a sterile drop of water on the agar to help smear the spores, and the zig zag should be wide, tight, and non-overlapping:



This one I use for MS crossing, for streaking dilutions, and general spore germination. If you use a minimal amount of spore with this, it's possible to catch monokaryons as they germinate sometimes:

I can't access a lot of this material.


What I would love is all the information relating to parasexual breeding.  I have been using and documenting that breeding technique for the past several years.  I  collected some amazing articles stretching back to some of the first discussions on parasexual breeding.

I will dig them up on my other system soon.  The quote I posted above was a list of some of the material you posted; i was unable to access some of your material. 

My reason for digging into this subject: Based on my experiences, I think a parasexual cross can serve the same function as a dikaryon x dikaryon cross.  i also claim a di - di cross between two proven isolates is one of the best breeding techniques. The magic i noticed is genes like size, potency, and yield are the dominant genetics expressed after parasexual recombination. 


When diving into parasexual breeding, you can follow under a microscope a live mitotic event of recombination to prove your cross. 

These ideals stretch back into the mycological literature far as the late 1800's.

this is my reasoning for digging into the topic as well, I appreciate your reply and insight.

Unfortunately those two papers/review of the paper seem to not be digitized as far as I'm aware.. still trying to locate them. Just added them to the list so its at least here while trying to hopefully find it

I might try to see if I can get a university library to scan it or something like that but I'm not sure how easy that is to go about either

edit: I think I was thinking of something else that I tried looking for, just checked the link again and saw you can just buy it for 30 bucks which I may eventually do if I cant find it

The review of the JR parasexual paper might be the one that is in a harvard library or something pretty out of reach.. not 100% sure

I will dig them up on my other system soon.  The quote I posted above was a list of some of the material you posted; i was unable to access some of your material. 

My reason for digging into this subject: Based on my experiences, I think a parasexual cross can serve the same function as a dikaryon x dikaryon cross.  i also claim a di - di cross between two proven isolates is one of the best breeding techniques. The magic i noticed is genes like size, potency, and yield are the dominant genetics expressed after parasexual recombination. 


When diving into parasexual breeding, you can follow under a microscope a live mitotic event of recombination to prove your cross. 

These ideals stretch back into the mycological literature far as the late 1800's.

That jr parasexual paper is one of those documents i could never find; i see it referenced in other papers.  I do have these following papers that relate to this exact subject, if you can't find them i can upload them:

Meiotic-like Recombination in Vegetative Dikaryons of SCHIZOPHYLLUM COMMUNE
C Frankel  1
Affiliations

    PMID: 17248942 PMCID: PMC1214059 DOI: 10.1093/genetics/92.4.1121

Abstract

A total of 65 Schizophyllum commune dikaryons of three different genotypes were synthesized, maintained on agar plates, prevented from fruiting, and macerated. The macerate was plated. Germlings of homokaryotic morphology were isolated using no chemical or genetic selection, grown, and tested for recombinant genotypes. Crossover types were plentiful among the homokaryons with recombinant genotypes, indicating that meiotic-like processes in vegetative dikaryons are common and may be as important as conventional basidial meiosis in the origin of recombinant strains.

This paper just shows how common parasexual recombination may be.  It helps me understand this terminology somewhat.

Have you read the OG paper?  The parasexual cycle in fungi?  Pontecorvo has a 1954 paper and one in 1956.. all very short and worth reading.

After that its always good to follow Roper and Pontecorvo up and down the time line.  Even buller gets into the ring surrounding this discussion; a lot of these papers are available online.. and they reference each other.

I can't remember how some of the later 1800's papers i read relate to all this, maybe  i was thinking of something else. 

I first glanced over this topic in the bible Introduction to Mushrooms.  Also Page 77 in the book Mushroom biology consise basics and current developments.  It speaks on Pontecorvo and paraxexual breeding.

I can probably get into weeds on this.. there is a lot of very cool stuff you can do with this topic.

thanks for your reply. I think I have read those but I'm not sure either..I went on a deep dive going thru all the references and citations too
I will add those to the main post

part of the reason of making the thread was to share but also just to help me organize/keep track of all the articles and stuff so I don't lose them

there is always an article or some reference I cannot find again and can never find the keywords to search and find it again or it takes me way too long lol

I'm probably going to just pay the 30 bucks for the jr paper from that website.. but I also read in their faq or somewhere that they might not be able to get every article listed or some bullshit lol

:takingnotes:

Would you mind elaborating on this, or linking the literature you are referencing?

Unless it's already in one of the links you posted.. just not connecting the dots for me right now though

Yes I will probably add those into the post eventually, that first one about protoplast fusion from 20 years ago is kinda crazy lol.

Although i think protoplast fusion and some of this stuff is way outside the realm of any home grower.. I thought I would add that section in anyway just for information sake.

There is post by muad.dweeb where he talks about the rattlesnake venom and how there is a similar idea with Trich produced enzymes because they act in the manner to lyse cell walls. I think one of the protoplast fusion links I added talks about using glucanex which is a product sigma Aldrich used to sell that was lytic enzymes made from trichoderma

Thanks for the the reply and posting those links!
