 Canadian researchers decode Cannabis genome

Canadian researchers decode Cannabis genome, find reason hemp differs from pot
October 19, 2011 - 570news.com
TORONTO - It's the same plant, but one type provides fibres for rope, while the other can make you high.
Now Canadian scientists, the first to sequence the genome of Cannabis sativa — the plant species that covers both hemp and marijuana — are beginning to understand why.
"This is one of the interesting things about us sequencing the genome of Cannabis sativa is that we hope to be able to use that genome sequence to shed light on these questions about how did hemp arise and how did marijuana arise," said Jon Page, a plant biochemist at the University of Saskatchewan.
Page, who co-led the research project to decode the genetic underpinnings of the cannabis species, said the plant likely originated in Asia, around modern-day Afghanistan and surrounding area.
Archeological evidence shows hemp textiles were used in China at least 6,000 years ago and shamanistic material from a Chinese tomb dated about 2,700 years ago was likely from the marijuana-type plant, he said Wednesday from Saskatoon.
Page said people likely recognized the plant had several uses: it was the source of fibres to make rope and cloth, as well as seeds that produce oil and contain protein.
"But they also realized that the flowers of ... the female plant were full of a chemical that could relieve pain and cause a sort of pleasant intoxication," he said. "So maybe what happened over time was those two uses — the medical and psychoactive — started to be separated from the rope and food use, and different types of strains were being grown for those uses."
That suggests that early farmers may have been engaging in selective breeding even thousands of years ago.
Co-investigator Tim Hughes, a molecular biologist at the University of Toronto, sequenced the genomes of both Purple Kush, a marijuana strain widely used for medicinal purposes, and the Finola variety of hemp.
He then looked for differences to explain why marijuana produces THCA, or tetrahydrocannabinolic acid, the precursor of the active ingredient in marijuana, while hemp strains contain a non-psychoactive component.
Page said analysis showed that the THCA synthase gene, an essential enzyme in THCA production, "is turned on in marijuana, but switched off in hemp."
The researchers, whose report is published Thursday in the journal Genome Biology, are making the cannabis genome publicly available for researchers worldwide.
Page said the data could help scientists better understand the plant's properties and lead to expanded uses. For instance, because Cannabis sativa "puts on a huge amount of biomass each season ... there's the idea that it could be used for producing biofuels in an efficient way."
On the medical side, knowing the genetic makeup of cannabis could aid the development of drugs to treat pain, without the side-effects of straight marijuana, added Hughes.
"People want a painkiller, but they don't necessarily want to be mentally incapacitated," he said. "So if you could make variations in the molecule, that would increase the painkiller effect but decrease the effect on your mental capacity. For most people using it, that would probably be a step in the right direction.
"Although for others," he said, laughing, "it might not matter."
Page said there is also a potential forensic use for the genetic data, with law enforcement interested in tracking illicit marijuana. For instance, he said one police force wondered if stalks left in a harvested field suspected to have been a marijuana crop could be DNA-fingerprinted and the results used as evidence in court.
"So DNA is a useful way of finding out the identity of a sample. People are identified by their DNA samples; plants can be as well."
Page said Cannabis sativa is the first medicinal plant to have its genome sequenced, following the decoding of non-medicinal plants like rice and corn.
Surprisingly, the genome for the opium poppy has not yet been sequenced, perhaps in part because it is estimated to be three to four times larger than that of Cannabis sativa.
"But the way things are going," said Page of the speed at which sequencing can now be accomplished, "I would fathom it's right around the corner."

There are a few non genetic strains with a RETARDED amount of THC/CBN content. One I know for sure is Headband, some samples have tested it at around 32% Thc. Thats just from selective breeding. Holy shit my mouth waters at the thought of genetic engineered strains. Imagine a 40 or 50% strain. The flowers would probably look like pure white crystal coated, resin dipped pedals of perfection. "God" may of made cannabis but we are about to make it even better.

Lol when that happens a new level of being burnt will be introduced.. but its all worth it.
this type of shit makes me want to be a scientist.. i wonder if they drug test the ones doing this, if not i might have to look into it

Do you have any literature / evidence of cannabis testing at 32% THC? I just don't believe it~ if someone tells me that their bud tests higher than 23-24% I usually just think they are assholes lying about their bud

Its in one of meh friend's high times. Test were done at some lab in California. I also have heard chemdawg being around 28%. I think I'll do a bit of looking around online today to see what info I can find.

here's the link from full spectrum labs with the report on headband. (they did only cannabinoids, not pests, hvy metals, or microbio, which is more important, imo)
Headband GCMS
25.05% assayable cannabinoids, 22.01% caluclated active cannabinoids
very respectable, but not >30%
eta: full spectrum lets you look up tested strains by name or percentages. Found one over 30%:

Man thank you for that, and I thought my 24% was high!
Time to find my ass some White Dog
Thanks for the info very appreciated

Man I Love headband, had it once over here on the east (was actually headband not just someone saying it is) and it was truly some of the best bud I have ever had.
Gonna have to try and find some of this "White dog"  <3

Have yet to smoke some headband myself. I saw the link for whitedog, but I did alot of looking around online and couldnt find a single strain review or anything, as where the opposite is true about headband. I wished I lived in a medical state, if legit headband came through my area.. It would cost about $500 an ounce

I have some headbang OD bubble hash right now that is just fucking killer! No resources to see if it was tested for amounts of THC, of course; but it sends you sky high 
I posted up a pic in the post your dank thread a week or so ago~

I had headband a few times. IDK if it was legit, but it was some of the best weed I have ever smoked, ever.
