GM Crops Create Herbicide-resistant "Superweed"

An anonymous reader writes "According to this article GM crops under test in the UK have cross pollinated to weeds, giving them the same resistance to herbicide as the GM crops. The article also mentions that this has been reported as occurring in Canada, which like the US is well past the test stage and allows widespread use of GM crops. What's worse, in Canada crop rotation has conferred multi-herbicide resistance to some of the weeds!"

  1. Is it gene transfer? by PCM2 · · Score: 3, Interesting

    What's not immediately clear from the story is how this happened. They say they found the resistant plant in a field where GM crops were grown. They say they treated the weed with herbicide and it suffered no ill effects. But does that mean the weed got the herbicide-resistant gene from the crops or did it evolve the gene on its own, the same way that bacteria that are exposed to low doses of antibiotics can develop resistance?

    I've mostly read about GM crops that are resistant to RoundUp. It seems pretty unlikely that a plant would independently evolve resistance to that herbicide. But what about the glufosinate-ammonium herbicide this plant was immune to? Is it possible that plants could evolve resistance?

They're American allies, after all, gotta make sure they get the benefit of American "intellectual property", to say thanks and make sure they can maintain their grip on power. OLh, wait, that was the wrong link! That's just about GM coca that's four times bigger than the normal plants, this is the RoundUp Ready[tm] coca plant story. My bad!

    Returning to the topic - IIRC GM crops were eventually rejected in the EU a few years ago after a lot of hoo-haa when Monsanto et al tried to railroad them through. However as others have pointed out, wind-borne pollen doesn't tend to respect national boundaries... :(

    While attending Purdue we had our favorite Monsanto rep out lecturing how he invented/patented certain processes using copper on platinum. Very fascinating from a chemistry and engineering point of view.

    While their, several of my fellows ripped into him in regards to some reports that ragweed had crossed with soy to produce an herbicide resistant ragweed. Cross pollination was the cause.

    The rep pointed out that all 'leftover' crops are considered weeds, and to just use another herbicide to prevent the spread. Good points.

    "Farmers in Canada and Argentina growing GM soya beans have large problems with herbicide-resistant weeds, though these have arisen through natural selection and not gene flow through hybridisation. Experiments in Germany have shown sugar beets genetically modified to resist one herbicide accidentally acquired the genes to resist another - so called "gene stacking", which has also been observed in oilseed rape grown in Canada."

    That's really something: even if there isn't gene transfer from related species to confer pesticide resistance, good ole evolution will take care of it.

    The article includes neat things too, like superweeds causing trouble on farms (they require dirty, now heavily regulated herbicides to kill) and wildflowers (AKA "pretty weeds") picking up resistance.

    If people have been using this weed killer for years, it would be a strange co-incidence for the resistance gene to just show up three years after GM but not one or two. Transfer by cross fertilization looks like the most likely method, especially if the find the very same patented genes. Transfer to other people's crops has already happened, much to the dislike of those who wanted nothing to do with GM and considered it polution.

    Clean up what exactly? There is no need to 'clean up' weeds that have resistance to a particular pesticide. The problems is entirely one for the manufacturer of the pesticide, as the chemical will no longer be as effective in the areas where the 'super weed' is prevalent.

    You see, it's not as if these genetic modifications make the weed species invasive. It just gives the weed the same chemical resistance as the crop. These weeds were around previous to the use of the chemical. Now with the resistance gene they can continue to be around, even when the chemical is used. Again. Nothing to clean up.

    Well, perhaps you are just worried in the abstract about some artificial genes sticking around in free-growing weeds. I'm not. Once the pesticides are no longer used, the genes will no longer confer any selective advantage. They'll then be subject to random mutations and errors and become quickly non-functional.

  13. Testing must take place over a generation by Anonymous Coward · · Score: 1, Interesting

    The problem with GM crops is that because nature is a complex interaction with thousands of variables (bacteria infects plant, gets eaten by insect, which gets eaten by frog, which gets eaten by larger preditor and so on), you have to test combinations and variables through an entire generation. The regression testing becomes a nightmare. The other half of the problem is the idiots shouting 'nothing bad will happen' when they don't know. I have an uncle who said that he didn't think that there was anything wrong with advertising on the internet, and he thought that those 'lab closet academics' who called it spam were just anti-business, and needed to cut their hair and get jobs. A few years later, he saw the problem in a clearer light (he missed it before) and began getting tired of spam. Suddenly the long-hairs aren't so dumb after all (but alas, spam is still with us). GM canola (rapeseed), got killed in Canada because no one would buy it (the farmers were wary of Monsanto's claims too). It might be possible to create safe genetically modified food, but it's a bit like adding animal waste products from rendering plants into animal feed (and getting mad cow disease as a result). For 10,000 years people just fed cows grass, and no BSE. Piss around with nature, and she will shit on you. GM crops? Sure, BUT you MUST PROVE BEYOND ANY DOUBTS that it REALLY IS SAFE FOR PEOPLE AND THE ENTIRE ENVIRONMENT! Genetic regression testing through several generations. The crop manufactures have a much much shorter profit/loss timespan and are usually unwilling to test properly. It does me little good to eat the GM wheat this week and die 5 years from now, or grow a 3rd ear, or have kids with heart, kidney or mental problems. Tinkering 'just a little bit' usually results in the 'butterfly effect' (a butterfly creates minute air currents, which under the right conditions creates a storm system which turns into a category 5 hurricane). A small genetic modification can do the same. If you aren't 100% certain, then don't do it.

    I used to be an anarcho-capitalist, and then I grew up. Anarcho-capitalism is one of those beguiling ideologies that looks great on paper, but it useless in practice.

    It's useless in practice because most of the underlying assumptions of anarcho-capitalism don't hold in practice. For example a) information is not equally available to all, b) information does not distribute equally among all, c) people do not make rational decisions (look up the research on non-transitivity of consumer preferences), etc, etc.

    Before you write me off as some left wing pinko liberal, I would suggest you read some of the more recent published material on markets and topology (yes topology!) -- the Fields Institute is a good place to look for such material. They will give you a very different perspective on the market that you trust so implicitly.

These offspring produce flowers in all sorts of weird colours I'd never seen before (including blotched and spotted), and some of the flowers are *wrinkled*, like crumpled newspaper. Not only that, but some specimens are freeze-resistant (petunias are a perennial, but normally quite freeze-sensitive and easily killed by cold).

    So I went looking for info on the weird colours, and learned that the new colours now seen in commercial petunias were created by adding a gene from, of all things, corn!! Apparently with a few more side effects than merely adding new colours to the petunia gene pool. Of course most people replace them every year so never see what happens when they're allowed to reproduce at random.
