I've been doing a lot of research lately on inoculating with mycelium water created by blending up a myc sample.

Now, we have all seen four distinct colonies radiating from the inoc points on a cake. These colonies are comprised of spores that have germinated in the substrate and formed a cooperative network comprised of numerous individuals.

My question is this: Can a pure (one set of genes) colony of myc be obtained from taking a sample of one of these colonies? Or, can one assume that this can only be achieved if the sample tissue is taken from a fruit stem?

If one took a small, rhizomorphic sample from one of these colonies, could he increase his chances of getting a colony with the same genes by doing or looking for something special?

From what I've read, yields can be almost doubled if your jars are colonized by a specific individual, as the individual gene set cooperates with "itself."

Your ideas and advice are appreciated

Well, since no has commented, I'd thought I'd let you guys know what I've discovered so far.

There seems to be some debate as to whether or not colonies share genetic information between individuals, just as bacteria do through sharing phages through conjucation tubes. If so, then as the colony matures, the genes of each individual would gradually become more and more like those of the whole colony. Only the favorable genes would be shared most often as cell division would be in favor of better adapted individuals; more cell division = more cells = more genetic material shared. This makes sense, as one would not expect a colony of 1,000 individuals to cooperate well enough to produce anything but very tiny fruits.

So, if we assume that myc colonies are comprised of individual cells that share genes, to create a very cooperative colony, each individual cell should have the same genes as its colonial neighbors. However, as nature takes its course, the colony will become a genetically homogenous group of cells if given enough time.

Following this line of thought, if one cannot obtain a stem sample to clone, any substantial myc sample taken from a young colony may have several different individuals in the beginning but will eventually become genetically "one," for better or for worse.

What are your thoughts?

well, there are some benefits in the long run for diverse myc. cultures, if a pure strain is used it is more susceptiple to disease/death by contam. because what will kill one part of your culture will kill it all, whereas with a diverse culture you have a better chance that one of the sets of genes will be more able to fend off or be immune to any said attack. in theory, a colony of myc. in a cake will NOT be genetically homogenous, where a fuzzy mess will sprout is where the spores settle/where the spawn lays, and unless it was a pure cultured cake to begin with it is highly unlikely, but not impossible, that the colony is a pure culture.

with spores, keep in mind that a single spore will produce a colony of cells called a monokaryon which will never produce fruits, it takes another compatible monokaryon to encounter, mate, and exchange cytoplasmic and genetic material to produce a dikaryon which IS able to fruit.

i suggest you get yourself an agar kit and play around, the best way for you to learn about this is to see it happening.

Hey, that's a damn good point. I hadn't thought of that. So, unless you're very sterile, you might just lose everything to that one particular contam that has your individual's number.

What do you think about the genetic exchange debate? Like, for example, inoc'ing with pans and cubes, same jar, to increase the overall potency?

Quote:

Again, do you think it would be possible to isolate a pan spore and a cube spore, introduce them to agar, and obtain a dikaryon from the colony? I doubt it, but I suppose it would depend on the number of chromosomes each have. Anyone know where this information can be found?

Good idea!

Thanks for the response :smile:

if i'm understanding mushroom genetics right, only one in 4 pure strains of cubensis is actually capable of fruiting. would this mean that obtaining a pure, fruiting strain of cubensis via cloning would result in substantially better flushes? would it also mean better pinsets?

That's the idea. A pure strain, one individual dikaryote, should be better able to cooperate with its own divided cells in the colony to produce some of the biggest fruits and largest flushes possible.

However, there seem to be a lot of factors that may or may not make the effort a success.

if you isolate a strand of rhizomorphic growth from one of your cloned isolates it will be better chances of bigger, even pinsets IMO.

but may not fruit. only 1 in 4 pure strains of cubensis is capable of fruiting. rhizomorphs are a good sign, but not a clear indication of fruiting potential. to obtain a pure fruiting strain from spores, one would have to isolate many strains on agar, then try fruiting each one to see if it could fruit. an easier and faster way to get a pure fruiting culture is to clone a fruitbody in my opinion.

if you isolate a rhizo from your cloned fruitbody is what i'm sayin, then it will be the same genetics only stronger.

how will two things which are identical not be identical?

well its not scientifically proven to have variations in a pure strain's mycelium, but, IMO, you are promoting only the strongest rhizo growth. i see what you're sayin though.

Here's another mention of genetic exchange among fungal colonies.

Can anyone point me to a good book on fungids? I'm looking for something advanced, as I've had all my bio and chem classes.
