Marijuana genome sequenced
Direct manipulation of the cannabis genome could yield some interesting results!!!
:smoker:
McKernan says he was turned on to the idea of sequencing cannabis by a 2003 publication in Nature Reviews Cancer about the many potential uses – including fighting cancer – of cannabinoids. C. sativa makes about sixty of the compounds. Although THC has gotten the most attention, McKernan hopes his company’s data will help scientists explore a few of the others, and perhaps guide plant breeding programs to generate new Cannabis strains.

Richard Resnick: Welcome to the genomic revolution
Yep, personal genomics labs are just a few years away! And, yes, there will be an app for that!!! :thumb:

Entire DNA sequence now available for less than £700
Another step towards biohacking at home becoming a viable and affordable hobby!!! :thumb:
An American company is offering clients the chance to have their entire genetic sequence of DNA read for $1,000 (£646). The “thousand-dollar genome” – an individual’s complete genetic information – is being offered by Ion Torrent, a division of Life Technologies Corp, which is based in Connecticut. The device takes up about as much space as an office printer and can sequence an entire genome in a single day rather than six to eight weeks required only a few years ago, its makers claim.

What’s the difference between plant DNA and animal DNA?
The structure of the genomes of plants and animals have a lot in common. "At the chemical level – the cells of all plants and all animals contain DNA in the same shape – the famous “double helix” that looks like a twisted ladder. What’s more, all DNA molecules – in both plants and animals – are made from the same four chemical building blocks – called nucleotides." This leafsnap idea if stretched to do genetic analysis in the field would be an amazing little gadget! I wonder how long before it's possible!
:sunshine:
Research shows that plants and animals may produce some proteins in common. One prominent example is known as Cytochrome C. But because the DNA copying process is imperfect, mistakes accumulate over time, making Cytochrome C slightly different in different creatures. The gene regions that specify the amino acid sequence in human Cytochrome C are more similar to those in another mammal like a rabbit, and less similar to a more evolutionarily distant creature, like a sunflower.

Beyond the thousand-dollar human genome
There are still plenty of problems when it comes to individual genome sequencing. For one thing, the information requires a terabyte of storage. Secondly, the resulting sequence still has an unacceptably high error rate.
“It might be true that the chemistry behind getting a genome sequence is $1,000, or will soon be a $1,000, but we all laugh about the $1,000 genome and the $100,000 analysis that has to go along with it,” said Rex Chisholm, the dean for research and professor of medical genetics at Northwestern University’s Feinberg School of Medicine. “That’s the reality of where we are today.”

How scientists resurrected a 30,000-year-old flower
No info about how the genome of this plant compares to its modern-day relatives, but I'm sure that analysis will done before long!
:thumb:
A few years ago in northeastern Siberia, Russian scientists uncovered a rare trove of immaculately frozen Arctic squirrel burrows dating back to the Ice Age. Inside they found buried seeds, including the fruit of a flower called the narrow-leafed campion. Now, after 30,000 years, they've brought the original flower back to life.

Can You Really Sequence DNA With a USB Thumb Drive?
Maybe it's not so unrealistic to think that a SmartPhone will be able to do DNA sequencing in a few years! :pacman:
Clive Brown, Oxford’s chief technology officer, tells Wired that the MinION works as advertised. You put a handful of lysed cells — cells whose membranes have been dissolved — into a small container built into the USB drive. You plug the drive into an ordinary PC. And depending on the length of the DNA in those cells, you’ll have a complete sequence in somewhere between a few minutes to a few hours. The device — which is used once and discarded — is the result of seven years of research, Brown says, and it sells for $900.

The market for DNA sequencing is a crowded one. Companies such as Illumina and Sequetech build large machines that sit alongside a lab bench, and Ion Torrent, a subsidiary of Life Technologies, will soon release a benchtop sequencer that it says will read the entire human genome — roughly three billion base pairs — in a day. But Oxford is the first to put this sort of device on an ordinary laptop.

The First Drug Made by Genetically Modified Plants is Approved for Human Use by the FDA :yummytongue:
Another breakthrough in plant genetics! I wonder if this modification changes the way these carrots taste.
The ability to manipulate the genes of plant cells to produce certain human enzymes isn’t new, but up until now concerns about human biologics derived from plant cells have kept them from gaining traction with the FDA. But plant-derived biologic treatments have proven successful in drugs given to animals in recent years, and for the first time the FDA seems to have softened its skepticism toward bio-pharmed treatments.
