Voyage To Sequence DNA From the World's Oceans

joehoya writes "Wired has an extensive article about an expedition with the goal of discovering new microbial species and new genes in the world's oceans. The expedition is led by J. Craig Venter, who is best known for his involvement in the race to sequence the Human Genome. This is a really fascinating expedition with a pretty high geek quotient. I know, as I set up many of the computer and other electronic systems aboard, and traveled with the expedition as far as the Pacific side of the Panama Canal. In fact, you can see me (ok, the side of my head) in one of the article's pictures, next to the Captain while helping to take a sea water sample."

      No one ever patented the human genome. I agree, patenting what exists in nature has no merit.
      Nevertheless, I think gene/DNA sequence patents will be very important and fair. There are a handful of researchers today who engineering new proteins and genes which are better than anything found in nature; others create nano-machines built out of DNA/RNA sequences. After millions/billions of dollars of research, dedication, supercomputing, etc. I think these scientists and engineers have every right to claim a patent on their creation. At the present time writing biocode is many orders of magnitude more expensive than contributing to sourceforge (i.e. expensive scientific equipment vs. a PC). Without gene patents, unless you're Craig Venter or Paul Allen and just have money to play with for the sake of discovery, there is no motivation what-so-ever to create future theraputics and bio-devices.

      I completely disagree. The delivery mechanisms and "bulk" structures can still be patented. But patenting genes themselves is a lot like patenting 1+1=2, or one-click shopping: there is a logical way to reduce it to its absolute minimum effort, so patenting that seems a bit absurd. (I should patent two-click shopping, or better yet, zero-click shopping: the site knows what you want and orders it for you without you lifting a finger.)

    Venter's genome survey is surely a dream geek voyage. But when he patents those genes, it's only his own dreams that will be coming true. Sure, Venter's entire career is built on public funding of open genomic science, back into which he declines to contribute. But even worse, many of the species he documents, and locks up for his own use, were developed over hundreds, thousands of generations of local people, coevolving and husbanding them into their beneficial condition. But Venter has the upper hand over the traditional genetic "developers", end-running them to capitalize on their innovations, only to license them back at a profit actually earned by his customers. Venter's technology is good, his science is great, but his economics is most foul.

      A scientifically careful approach to sequencing the human genome wouldn't have used any single individual's DNA--it would have selected the fragments and individuals it uses on a case-by-case basis, as work progressed. In the end, you would have ended up with sequences from many individuals covering many genes.

      It's no gimmick -- there's lots of ways to associate genes together. One way, which I myself was partially responsible for in this analysis (I got an acknowledgment in the original paper) is phylogenetic inference -- basically you can make evolutionary trees for each gene predicted, and you can assume that genes that fall into analogous clades across trees are either due to the same or dimilar organisms.

      Hey, I admit that the Sargasso Sea analysis was crude, and ten years from now we'll be laughing at it, but the fact is metagenomics is basically the only way to explore biodiversity at a molecular level. We'll be seeing more such studies (in fact we already have).

    I am a microbiologist (IAAM?), and while the notion of sequencing so much random genetic material is interesting, I can't really see much point other than hoping to stumble upon something unexpected. And even then...

    Yes, I RTFA, but I still don't get the point. Venter says he wants to create an artificial genome into which DNA could be inserted and tested... so crazy. You can't just stick DNA into a genome and "see what it does", you have to have the entire cellular aparatus to translate the sequence into protein. So, assuming that they somehow come up with an artificial cell (or use an existing organism with genome removed), SO MANY factors can affect the final form of the protein. You cannot assume that the protein will fold properly, unless it is constructed in its native cellular environment.

    And even assuming you can get the protein to fold properly... then what? He said he'd use robots to perform a million experiments at once, sure. So you stick the protein into glucose solution, and see what it does... and into fructose solution... and so on. Sure, you could do this with simple substrates, but what if the protein is designed to act on a combination of substrates, or in conjunction with other proteins!?

    So, it would seem to me, that the best you could ever hope to achieve with this approach is the discovery of ultra-simple proteins (which will fold correctly in any circumstance) which act upon ultra-simple substrates.

    Though, in truth, he states that he's looking for something to possibly break down C02, so perhaps if his focus is narrow enough, the discovery of even a simple protein might get things on the right track...

    Anyway, I guess it's not the way I'd go about doing things, but sailing around the globe sounds like a fun way to do research. Good luck, guys!

      The impression I got was that Celera was really formed because of huge egos and a conviction that their methods were better (which, in retrospect, they probably were), not because the scientists involved honestly thought this would be a great way to make money.
