Genetically Engineered Cannabis

[GMT]

Well I'm certainly not trolling chimera or anyone else OP, I'm just saying that the info he posted was wrong. Kinda the point in this place, someone posts up something and if someone with more experience on the subject notices that some info is wrong, they post up the correction so that we all get the best info we can on the subject.

Whatever the subject with cannabis NOTHING is worth fighting about it please... this is just a plant and we smoke it and laugh LOL so lets do that and have some fun here shall we?? lol peace out Headband707

 

[DocLeaf]

Chimera and me often lock-horns,, (possibly because we are similar),, but once dust settles,, we fully recognise him as a very knowledgeable Botanist,, passionate Grower,, dedicated Breeder... with a way with words ,, that often helps others learn about plant genetics

To that end disagreeing and discourtesy are two totally separate things. Please remember for every poster,, there's 10 lurkers,, all looking to find information about ganja. Positively together,, please let's push things forward (and help those lurkers),, otherwise we might as well all pack up and go home

- - -

Anyhow,,, now we all understand what a GMO is and the process behind their conception (thanks Chimera et al.),, it would appear that general opinion is divided as to whether Genetically Modified Hemp/Cannabis actually exists or not. (we say it did in 1995, and we grew some in 1996 until it terminated itself in 1997).

This alone raises more questions than we have yet (collectively) provided answer for on this thread... food for thought.

Peace n flowers ALL
One Love to the ganja growers

Edit: We'd add that we did NOT personally steal anything from the original fields. It was hemp! Besides,, I n I nah theif,, never have been,, never will be,, sein! Its not in my nature to rob what isnt mine. The seeds were collected from the tens of kilos of hemp that my brethrens stole from the farmer's fields (while we were with them!) sure. Just to set the record straight.

 

[GreenintheThumb]

We are not in disagreement. GM hemp does exist and has resistance to botrytis. No commercially available hemp has been genetically engineered. It's just researchers who've done this work.

 

[DocLeaf]

From the Cauliflower virus they use in the DNA altering sequence? Sure I buy into that

But what about other forms of genetic manipulation, with the desired effect the Pigs over here and the DEA over there and monsanto are really aiming for?

Please note,, i'm not in the 'tin-foil helmet club' ,,, and care not for rumor.. or misguidance,, however I dont exactly trust the ppl in white suits behind the doors that normal University students don't have card-slide access to,, if you get my drift. Not all information is made public... even in academic circles!

The idea that genetically modified hemp,, with terminator genes (wrong words but i like them) have not been trialled someplace,, should they exist,, is not far fetched. The fact that a otherwise feral plant vanished in one season (i work with weed species every day of my life btw,, and understand how wild species and feral cultigens work). aka the disappearing hemp,, (and the non-viability of seeds from x2 seasons from them) is still a complete anomaly to me today,, and remains a mystery over a decade later.

We're hoping you folks can PLEASE help us cast some credible light onto the shadows of time here .. with constructive comments ,, such as the one above (#144)

Peace n love

There's no more feral hemp? Is this your personal observation or are other people talking about it? What year did they disappear? Where?

 

[ShroomDr]

You obviously dont know the definition of engineered.

 

[GreenintheThumb]

You obviously don't know the definition of gentically engineered even though it's been posted in this very thread.

 

[DocLeaf]

Dude. Please start at the beginning of the thread,, post #1. Then watch this video about wild hemp in Nebraska, USA:

http://www.youtube.com/watch?v=R5IQ2PrSWG4

.. then jump in and add positive comments Its a process of learning

Edit: lol ,, sorry,, im mashed. appologies , i understand what you mean now

The 'suspected' GM Hemp grew , seeded, the seeds grew (feral c.1996), then they disappeared... in our gardens ,,, and the fields and ditches 15 miles away?

It's like a case for Moldy and Skully X marked the spot!

Normal breeding methods cannot account for that! or seed companies are missing something.!!! Example,,, fritallary seed could (we never would folks) source seeds that no-one could ever use for making seed stocks from (beyond the first season, then they all become infertile)!!! THATS BIG BUSINESS!!

Basically that's what happened with this hemp! Otherwise we'd still be managing swathes of it today,, in the wild,, feral,, on other ppls land (for game brids and deer to browse on)... that was our plan,, conservation via hemp

Fact is some genetics scientists squabbed us!

 

[ShroomDr]

Ive defined everything, you have failed to define acronym or engineer.



Engineers make your world possible, yet you have no idea what they do, nor an appreciation. I would have dropped this already, but its like your spitting in the face of every engineer that has ever lived, and has made your world possible.

Creating triploid seeds is certainly not GMO, but because there would be no natural populations, they are created exploiting their genetics to produce no seeds.

Engineering is just about the only thing humans do better than any other animal. Our memories are not any greater than an elephant, and we certainly dont have a firm enough grasp on animal linguistics to define ourselves king. Its ashamed your so short sited you think genetic engineering began in the 1970's with mostanto and big chem.

 

[GreenintheThumb]

First off, my father's a chemical engineer. Secondly, genetic engineering DID start in the 70s. You want to say every domesticated plant and animal was genetically engineered. Painting with such a broad brush serves no one. Finally, if you don't know what an acronym or engineer are please feel free to GTFO.

 

[DocLeaf]

You cant build anything material ,, without tools! even chimps understand that much.

(if you wanna chat semantics pm me,, i n i mastered that years ago,, we could bore the hind legs of a lame mule with the study of the 'contes n codes' of language ,, let alone getting onto any metaphor.. lol)

- - -

Sorry,, this is the best image we could find,, and capture on digital ,, seeds taken from said hemp fields and cultivated in isolation... the next season.

The plants made seeds,, but the seeds were infertile. As were the seeds from these plant's parents/siblings ,,,in the proceeding year... doesn't make sense... ganja is a weed! When even seeds from 1977 grew and these fresh seeds didnt ,, then we already started asking questions (?)

Hope someone can explain this... it was like weird science without the tits... worse than the day dem kids boiled the kilos of wild mushrooms and threw the water away while i was sleeping!!!

btw,, yeah that's a young DocLeaf ,, in a camo head-mask.. haha

 

[ShroomDr]

Painting with such a broad brush serves no one.

which is why ive been differentiating the ancient genetic engineering, and the new genetic modification. broad brush would be GE = GMO.
Ford=Auto; Auto≠Ford.



Exploiting genetics is engineering. Engineers create and exploit tools. Knowledge of genetic inheritance is a tool.


Products are labeled GMO, not GEO

One came first, before recorded history, one is a Ford (Pinto).

 

[GreenintheThumb]

Sure I guess genetic engineering is whatever YOU want to define it as. How could this possibly cause confusion, right?

 

[ShroomDr]

Is it confusing that an Automobile is not a Ford?

 

[GreenintheThumb]

So confussing. Good thing you're here to help clear everything up with the definitions you make up in your head.

If you're wondering I'm currently shaking my wigliggi at you...

 

[DocLeaf]

Please get a grip guys,, or DocLeaf starts hitting the triangles!!!

If you cant answer the questions posed,, please leave the thread (no offense,, youz all contributed good info. already why not again? pls be positive,, dem the vibes we nuturing)

Peace

 

[GreenintheThumb]

The answers have already been posted. And around we go again.


Doc as far as your hemp is concerned we don't have enough data to reliably say anything about your experiences. But since you were able to germinate and grow the seeds you guys stole logic would say it's not terminator technology.

University of California - Davis. "Plant Breeding Breakthrough: Offspring With Genes from Only One Parent." ScienceDaily 25 March 2010. 22 May 2010 <http://www.sciencedaily.com* /releases/2010/03/100324142012.htm>.

Plant Breeding Breakthrough: Offspring With Genes from Only One Parent
ScienceDaily (Mar. 25, 2010) — A reliable method for producing plants that carry genetic material from only one of their parents has been discovered by plant biologists at UC Davis. The technique, to be published March 25 in the journal Nature, could dramatically speed up the breeding of crop plants for desirable traits.

The discovery came out of a chance observation in the lab that could easily have been written off as an error.

"We were doing completely 'blue skies' research, and we discovered something that is immediately useful," said Simon Chan, assistant professor of plant biology at UC Davis and co-author on the paper.

Like most organisms that reproduce through sex, plants have paired chromosomes, with each parent contributing one chromosome to each pair. Plants and animals with paired chromosomes are called diploid. Their eggs and sperm are haploid, containing only one chromosome from each pair.

Plant breeders want to produce plants that are homozygous -- that carry the same trait on both chromosomes. When such plants are bred, they will pass the trait, such as pest resistance, fruit flavor or drought tolerance, to all of their offspring. But to achieve this, plants usually have to be inbred for several generations to make a plant that will "breed true."

The idea of making a haploid plant with chromosomes from only one parent has been around for decades, Chan said. Haploid plants are immediately homozygous, because they contain only one version of every gene. This produces true-breeding lines instantly, cutting out generations of inbreeding.

Existing techniques to make haploid plants are complicated, require expensive tissue culture and finicky growing conditions for different varieties, and only work with some crop species or varieties. The new method discovered by Chan and postdoctoral scholar Ravi Maruthachalam should work in any plant and does not require tissue culture.

Ravi and Chan were studying a protein called CENH3 in the laboratory plant Arabidopsis thaliana. CENH3 belongs to a group of proteins called histones, which package DNA into chromosomes. Among the histones, CENH3 is found only in the centromere, the part of the chromosome that controls how it is passed to the next generation.

When cells divide, microscopic fibers spread from each end of the cell and attach at the centromeres, then pull the chromosomes apart into new cells. That makes CENH3 essential for life.

Ravi had prepared a modified version of CENH3 tagged with a fluorescent protein, and was trying to breed the genetically modified plants with regular Arabidopsis. According to theory, the cross should have produced offspring containing one mutant gene (from the mother) and one normal gene (from the father). Instead, he got only plants with the normal gene.

"At first we threw them away," Chan said. Then it happened again.

Ravi, who has a master's degree in plant breeding, looked at the plants again and realized that the offspring had only five chromosomes instead of 10, and all from the same parent.

The plants appear to have gone through a process called genome elimination, Chan said. When plants from two different but related species are bred, chromosomes from one of the parents are sometimes eliminated.

Genome elimination is already used to make haploid plants in a few species such as maize and barley. But the new method should be much more widely applicable, Ravi said, because unlike the process for maize and barley, its molecular basis is firmly understood.

"We should be able to create haploid-inducing lines in any crop plant," Ravi said. Once the haploid-inducing lines are created, the technique is easy to use and requires no tissue culture -- breeders could start with seeds. The method would also be useful for scientists trying to study genes in plants, by making it faster to breed genetically pure lines.

After eliminating half the chromosomes, Chan and Ravi had to stimulate the plants to double their remaining chromosomes so that they would have the correct diploid number. Plants with the haploid number of chromosomes are sterile.

The research also casts some interesting light on how species form in plants. CENH3 plays the same crucial role in cell division in all plants and animals. Usually, such important genes are highly conserved -- their DNA is very similar from yeast to whales. But instead, CENH3 is among the fastest-evolving sequences in the genome.

"It may be that centromere differences create barriers to breeding between species," Chan said. Ravi and Chan plan to test this idea by crossing closely-related species.

The work was supported by a grant from the Hellman Family Foundation.
