are spores a "reset" to genetic origins?
    #7634099 - 11/14/07 08:44 AM (16 years, 2 months ago)

the point is: suppose a LC growing from spores. few milliliters of this LC are used to generate another, and so two o three more times. the 4th generated LC is used to grow mushrooms. the spores of these mushrooms carry the same genetic weakness of the mycelium they originated from, or got some kind of genetic "reset"?

I think your confused. The advice ive read says streach that first lc to as many others as you can, just dont clone what grows from it. The spores should be fine ime. What they say NOT to do is to clone the fruit you grew from a clone creating a second then third then fourth generation clone. LIke that tom hanks movie.

The spores themselves are always a new mix of genes sprinkled with some mutations. They're not a "reset" to an earlier makeup. There is no way of knowing beforehand if a certain genetic trait (eg. a "weakness") will be preserved or modified. A "weak" mushroom can produce spores that give more weak mushrooms, but also "strong" mushrooms.

A reason for cloning is that you preserve the genetic makeup - you know what you will get. With spores you have to wait and see the final product and then select what you're looking for.

Over many generations, you can keep desirable phenotypes from spores. I'm not sure how many generations it would take for you to see a noticeable change, though. The same can be said about any organism that you have reproductive and environmental control of. If you were looking to attain this, I'm assuming it's wise to create at least several grows from each parent. I'm of course referring to phenotypes observed in the fruit bodies, not the mycelium itself.
