      Already the inferior bitter tasting species, robusta, has twice as much caffeine as Arabica, the good tasting stuff. Already, a pot of purely robusta will give you the shakes. 20 times more caffeine might be lethal.

        If you drink five cups of it, yeah, it is.

        I think the LD50 of caffeine is right around 8-10 grams, and since one cup of joe on average contains 100 mg caffeine, the LD50 of coffee is roughly 80 cups of coffee. But, your body will burn off caffeine faster than you can drink all that coffee normally, so the only way to get that much caffeine from coffee directly is to pump it straight into your stomach - and even then, you're more likely to get internal injuries and diarrhea than a fatal case of coffee s

          True, you can die from caffeine, and it has happened. Probably seven years ago, when I lived in Boston, there was a widely publicized case of an MIT student who OD'd on NoDoze, after taking some unbelievable amount on a dare. Most of the talk was that MIT students should know better, and it interested me as anecdotal proof that intelligence and common sense do not necessarily equate.

    They are going to use the mapped gene literally as a map. Since Brazil has banned GMO's the genome will be used as a guide for determining which cross pollinations etc. will be most effective.

      Anyway, call me Dr. Stupid, but I think there is a substantive difference between having the means to be really selective about your breeding and splicing genetic code out of one species to put into another.

      It seems to me that we are where we are today because clever, patient people "genetically modified" their animals and crops through careful breeding. I don't see how what Brazil is proposing is different. I'm pleased that they'd using this method instead of going in with the high tech equivalent of knives and tweezers to play switcheroo and put genes together in combinations that nature hasn't pre-tested for us.

            That s not really right. On an individual scale, natural selection does not seek harmony with the environment. Natural selection seeks nothing, and tunes to nothing except the amplification of oneself. Organisms do not seek to live in harmony with the environment, they seek to exploit it the best they can. The environment (i.e., the other organisms around it) counter this by trying to exploit each other in the same manner. This is natural selection. Selective breeding accelerates this process drastically.

            Where a gene may provide a benefit that will increase its frequency over a period of several thousand years under the influence of natural selection, selective breeding can do it in a century or less. Selective breeding is far from a natural process. Selective breeding acts on one species, and accelerates the selection in that species for a given trait or set if traits. The surrounding species (the environment) do not experience the same increase in rate.Remember; I am not comparing GM to natural selection, but to selective breeding.

            if breeding created a more hardy competitor, don't you think nature would have created it by now over the 4.5 billion years it's been at work?

            This should be fairly obvious, but it has resulted in a hardier competitor. Many, many times. That's evolution. And simply stating that something is "flat out destructive" does not make it so. I'm not saying that GM is de facto safe, just that it's not by default unsafe, either. In fact, the resarch that has been done points to "safe".

            Also, I can't think of a single mechanism other than improved hardiness that would cause an organism to be destructive. Otherwise, it wouldn't be able to compete with indigenous species and would be wiped out.

    Bloomberg has a story [bloomberg.com] that's less cutesy but more interesting. Some excerpts:
    ``This a jump of at least two decades in the race to unlock the coffee genome,'' Brazilian Agriculture Minister Roberto Rodrigues said in a statement on his ministry's Web site.

    A two-year government project studied 200,000 sequences of coffee DNA and identified 35,000 genes, which in combination give the drink its flavor and aroma, the statement said.

    The DNA database will be open to Brazilian companies in about five or six years, and foreign competitors will be able to access patented information on payment of royalties, Clayton Campanhola, the head of Brazilian agricultural research agency Embrapa, was cited by Reuters as telling journalists in Brasilia.

    Rodrigues told reporters that Brazil would produce a ``super coffee'' through cross-pollination of coffee plants and not through genetic modification, according to the British Broadcasting Corp.

    Brazil has banned the planting and sale of genetically modified crops.

    This makes minimal sense to me, although it does explain why the other stories don't mention a publication. They spend two years, it's a jump of two decades, they're done but Brazilian companies can't see the data for five or six years and foreign companies will have to offer royalties? Pardon my cynicism, but what exactly do they have right now? Some shotgun coverage? ESTs?

    Meanwhile, this is a few months work for any of the major genome centers. If there's really any commercial value to this, I can't imagine the coffee industry wouldn't just sponsor a publically-available ccommercial genome, like every other major agricultural crop has or will have. No one is going to wait five years and then give Brazil royalties.

      They're probably ESTs. I think the coffee genome is 500-750Mb (depending on the species), so 200,000 shotgun reads are only going to give you 20% of the genome at best. No way you'd identify 35k genes from that.

      You're right - it's hard to see the value of this. WashU does that many sequencing reads in a day - it would probably cost about $1M.

      Normally I'm happy to see scientists get recognition for their hard work, but if the data isn't public then, really, why should anyone care?
