Warloc730 is beginning to sprout.

I've heard that it is only possible to clone a plant up to 65 times before "cell degradation" occurs, and you must start cloning a different plant. I never really understood how the cells could degrade. Can anyone explain this to me?

Hey Warloc...

As far as i know, there's very little "cell degradation" from clone to clone;i consider logical that such a thing must have an end, but Soul/Sly say it's allright for life...

This should be a good one for Highguy, it's a shame he's not around; Do you have any idea of where he might be???

I'd say a good for D9 as well But I have heard the same thing as Warloc730 ... Somthing about 7 years rings a bell as well. Someone more versed in genetics would know I bet.

I have heard of it, but I can't find anything written about it. I do recall reading once, I can't remember where, that it wasn't true. The problem seems to be having no genetic diversity and becoming infected with something. If you keep the mums healthy generation after generation they, in theory, should remain healthy. Mind you, I'm no geneticist...
One of the strains I have has been clones to mums for years and they're still going strong, hopefully at least once more cause I'm choosing new mums now...
If anyone can find more information from a good source please share..

D9, your post got me thinkin', and I came up with a few theories.

::War suddenly has a flashback to his high school years in biology (too much bad drugs)::

Theory #1
A virus can go dormant while in a cell and attach itself to that cell's DNA. After that cell has replicated (while replicating the virus, free of charge ) for a while, the virus will stop its dormancy and come out of the DNA to complete its age old task of destruction. If you were to clone a plant very many times, it would become a host to an absolute farm of dormant viruses, possibly many viruses per cell with the possibility of coming out of dormancy at any time.

Therefore, after a certain number of times a large plant is grown from a small cutting, the plant will be infested by dormant viruses which are always trying to destroy the plant.

Theory #2 (just as logical, but a bit more understandable and readable)

Bacteria are always at war with the plant. The plant's very specific immune system to bacteria is cloned along with the rest of the plant. After the immune system of the older plants kill the bacteria that it can, the bacteria that are immune to that specific plant will thrive on the newer plants, and the process will refine itself again and again until a type of bacteria evolves that can cater to exactly the type of poison that the plant will need to become weak. This process of evolution has already been proven by antibiotic immune bacteria that live in humans that doctors can not fight anymore.
----------

This kinda seems to me like viruses and bacteria are just God's way of insuring that none of us (or any plant) will ever acheave immortality.

The way I see it, there are a few ways you could elongate the time it would take for the viruses and bacteria to take over.

1. Keep your area clean. Hydro farming would help this out by quite a bit.
2. Keep you moms alive as long as possible, take as many generations of clones from one mom as possible.
3. Choose a mom that seems to have a strong immune system.

Tell me what you think.

-War

Wow TCC you have been bumping all these great Warloc threads of late, its a pity he isn't around to answer them himself...he has probably forgotten all about us here at hc.com

I have had some moms for 7 to 8 years now maybe longer, at times they have been ill but with good luck and clean techniques I have always resotred their health and the health of the subsequent cuttings, I think Warloc raises some interesting angles though in regard to RNA adaption of viruses and their translocation though.

what about this:

Jorge may have been correct at the time but it is understood now in humans and the process seems to apply to all life.

The short version is that each time a cell divides its telomere gets shorter. No more telomere, no more life. Science is coming close to being able to regenerate these strands and lengthen the clock.

"There is substantial experimental evidence that cellular aging is dependent on cell division, and the total cellular lifespan is measured by the number of population doublings or cell generations, not by chronological time (1). This means
there is an intrinsic process, occurring during cell growth which culminates in the cessation of cell division. Cellular age is regulated by a genetically determined counting program which controls the number of cell divisions."

LR, please explain then, why they found "dolly" the sheep that was cloned, to have same genetic "age" as her clone mother? This is all current info, is it not?
