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!"

    You really think these companies do it to feed the poor ? Actually, they do it to put some IP in their seeds, and then prevent farmers to reuse their seeds the next year. Do you think they do it to reduce the usage of chemicals ? Actually, they also produce the chemicals, that you cannot use without agreeing to use their seeds. Their tactics are disgusting, and moreover, these practice are a danger for the environmenet, because it is impossible to prevent dissemination of the resistance genes into other species.
    And yes I am a scientist (biologist), and no I am no "greenie" (I am in favour of nuclear power, but next to renewable energy sources).

  4. Genes as IP - is Monsanto now responsible? by bstarrfield · · Score: 5, Insightful

    This was predicted years ago. When Monsanto and other firms first started applying for patents for "terminator" genes (plants that will not generate viable seeds for the next years crop) and for plants specifically resistant to the use of "Roundup" many biologists warned of the danger of cross-polinization. Monsanto, et. al., and their political backers scoffed at the suggestion.

    It gets far worse. Let's say a GM crop was planted next to your farm. Due to wind, bees, eh, nature the GM plants spread to your field, and soon you're growing GM plants. And then you're sued for stealing the GM crop. For the basics of wacky Monsanto GM chaos see Organic Consumers.

    So, if Monsanto, et. al. want to own and control the GM crops - and the GM crops now spread to destructive speices, what do you think the odds are that the firms responsible for creating this mess will have any liability?

  5. Cross polination is a myth by jurt1235 · · Score: 5, Informative

    Two different species are geneticaly incompatible to produce a viable offspring. In a rare case two closely related species are capable to creating offspring which is usually not able to reproduce.
    Just resistance because of stupid use of herbicides and pesticides is more likely. When using herbicides and pesticides, it is important to keep a healthy population to overgrow the by herbicides affected population. The change is pretty large that the new survivor is maybe strong against the poison, but weak compared to the original plants. This has been studied, and it is shown that by spraying 90% wiht pesticides or herbicides, and leave 10% of the original population untouched, the poison tends to be effective for a longer period (up to 10 years longer on the same pest). The only issue is, is that 10% of the harvest needs to be sacrificed to the pest.
    In the end, every pest gets immune.

      Actually, the cross was between oilseed rape and charlock, previously presumed to be too distantly related to allow cross-pollinaton. As a general rule, plant sex is way more complicated than human kindergarten-variety sex (it has diploid and tetraploid genes, alternation of generations, and other bizarre complications including susceptibility to mosaic viruses), so the ordinary sex paradigms and assumptions are suspect. Scientists regard this cross to be more than interesting for the right reasons, in other words.

      I think you mean fertile, not viable. Plants are dirty whores. They'll have sex with just about anything and, a surprisingly large number of times, viable seeds will result. The plants that grow from these seeds are generally infertile (not unlike a mule), but not always.

      As for the "only kill 90% of 'em" comment. It comes out of antibiotic research... and while I'd be wildly suspicious of anyone trying to draw a direct analogy between bacteria on a petri dish and multicellular eukarya in the wild... you don't even have the regiment right. Basically it was the comparison of the evolution of antibiotic resistance in bacterial populations where a plate was allowed to be recolonized by suriviors v. a plate that was reseeded with the wild population. The analogy to farming would be to purposefully plant non-resistant strains of undesirable plants so they could compete with any resistant varieties... not "don't kill all of 'em".

    "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.

    It's not just "greenies", Europeans are wary of GM foods (especially in England, where there have already been too many food and meat scares in the last few decades). GM foods are closely regulared by the EU.

    Farmers in China who grow GM crops were shown to use fewer insecticides and are living healthier lives for it, but I'm not sure where you're getting the bit about starving people from, I haven't heard of that happening. As you said, those people aren't starving for lack of food in the world (and I've never heard the "greenie" argument that there is not enough food, only that food distribution is poor -- this is called a humanitarian issue, not an environmentalist one).

    It's pretty hard to find non-GM foods here in the US. I haven't noticed any difference for the better in their shelf life, either. In England, I bought all-organic for the same reason as your better half, but it's far too expensive to do that out here (in the States). When I bought the cheaper GM foods, I was surprised at how quickly they rotted, even in the fridge.

    You're damned if you do and you're damned if you don't: truly organic food (insecticide free) is too expensive and time consuming for us, insecticides make my wife sick (she grew up in a farming community and was thus exposed to too many nasty chemicals), and GM foods are just plain rotten.

  10. Hysterical Junk Science by Shannon+Love · · Score: 5, Insightful
    This article is so bad it almost defies description. One almost doesn't know where to start:

    (1) There is nothing "super" about the weeds, they have merely acquired resistance to herbicides. They don't grow faster or crowd out crops more aggressively than their non-resistant cousins. It just as stupid as calling anti-biotic resistant microbes "super" germs. "Super" is a term meant to imply something new and unusually powerful and deadly. Every weed growing in every crop area in the developed world is largely immune to pesticides that entered widespread use over 30 years years ago. Are they "super" weeds as well?

    (2) The article presents no evidence that the acquired resistance is in fact the result of cross-pollination and not natural evolution. In fact the artical says that:

    "The new plants were dubbed superweeds because they proved resistant to three herbicides while the crops they were growing among had been genetically engineered to be resistant to only one."

    This strongly suggest that the resistance is naturally acquired. It also doesn't seem that anyone took the elemental step of sequencing the pest-plants to see if they are actually using the same genes as the engineered crop plants. Unless someone can show that weeds contain engineered genes this article is nothing but hysterical supposition.

    (3) We have been breeding herbicide resistant crop plants using radiation and mutagenic chemicals for over a century. Where is the evidence that gene transfer has occurred using the older technology? After all, nature doesn't care where the genes came from only whether they benefit the species they jump to. If acquiring herbicide resistance from crop plants was a major problem we would have seen it long ago.

    (4) The supposition that crop plants will spread quickly through the wild is garbage gainsaid by centuries if not millennia or practical experience. We force crop plants to divert resources from their own survival in order to produce the plant products we need. As a result, they cannot survive in competition with natural plants that do not have the artificial overhead. If not protected from natural competition they are quickly wiped out.

    Opponents of GM crops also neglect to mention that if genes jump across species as fast as they claim then the problem will be economically self-limiting. The GM crops are only used because allow the easy killing of associate pest-plants. If the pest plants acquire resistance rapidly then the GM plants lose all their economic advantage. No one will use them because they will offer no benefits for their increased cost.

Unless Monstanto et al can guarantee that the modified genes will not get loose and hybridize with wildtype plants in adjacent fields they are introducing harmful genes into the environment for their own benefit.

    The Monsanto Terminator gene is the perfect example of this: Terminator-infected plants will hybridize with wildtype plants in adjacent fields, resulting in progressive sterilization of surrouding farms.

    Well, the parent is just wrong. I'm a former botany student with an emphasis in molecular biology and genetics. With animals, you can't usually get unrelated species to crossbreed (but even that's not absolute). With less specialized organisms, well, the rules are a lot less strict. Bacteria, for instance, swap genetic material across species lines all of the time, and often will have specialized "sex organs" for that purpose. Plants aren't quite so loose as that, but they can, and do, regularly cross species boundaries to some degree, and even manage to pull off viable reproduction when a cell division fails at the growing tip (doubling the chromosome count, and in effect generating a new species.) In addition, many weeds are crucifers, related to the rape (canola) plant, making that particular crossover especially likely. This is a real problem, recognized by real scientists.

    Hee-freakin'-haw. Every biologist who doesn't actually work for Monsanto or Cargill saw this one coming decades ago. Families like the brassicas are more promiscuous than a San Francisco bathouse. They cross breed all the time with their wild relatives.

    It doesn't even take sexual reproduction to do it. Plant viruses transfer genetic material from one plant to another sometimes completely unrelated one. All it takes is one or two out of billions to start the evolutionary ball rolling.

    The whole point of the exercise was to sell more herbicides. By making the crops herbicide resistant you encourage farmers to change the way they farm to buy tons of the stuff. There are other methods that produce more nutrition per acre - and even per dollar - but they don't sell the product that the agrichem industry is pushing.
