GMOs Perfected Down to the Chromosome Level

Roland Piquepaille writes "If don't like the concept of 'Frankenfoods,' I have bad news for you. U.S. researchers have developed an artificial chromosome for corn plants. The Chicago Tribune reports that researchers can now make chromosomes to order. These artificial chromosomes are accepted as natural by the plants and passed through generations. As the Monsanto Company bought rights to use this mini-chromosome stacking technology in corn, cotton, soybeans, and canola, I guess we'll soon eat food made from permanently genetically modified organisms (PGMOs?)."

    The article summary is deceptive. Inserting a gene into the current genome of crop is just as permanent a change as added a new mini-chromosome. In either change the changes will be inherited by the offspring of the individual plant.

    The main difference between this technology and currect methods on inserting genes is that more than one gene can be added as easily as a single gene, whereas in the previous system "stacking" multiple genes required much more effort than a single gene, since each had to be inserted individually and then combined using conventional breeding.

    I for one think this technology is a step in the right direction, as it will make it easier to create artificial species barriers, which require two-five genes to be inserted, but would prevent GM crops from crossbreeding with traditional varieties in the field. THIS IS NOT TERMINATOR TECHNOLOGY! The plants would still be fertile, just only with others carried the added chromosome.

    But couldn't they have found someone besides Monsanto to implement it?

    The case is nowhere near as straightforward as most people seem to believe. If you research the details, he bought massive quantities of Round-Up, which was basically the first smoking gun in Monsanto's case[1].

    The quantity of Round-Up be bought exceeded the amount that could be applied to his non-crop acreage, ruling out the possibility that it was purchased solely for border weed control etc. This was a very strong indication that he not only knew he was growing RR Canola, but that he was actively selecting for it by spraying his fields.

    The other smoking gun was the fact that his crop was 95-98% RR canola[2]. That level of 'contamination' indicates very aggressive, active selection for the target genotype. You do not get that from the trace contamination due to windblown seed or accidental cross-pollination.

    I don't doubt that the first few plants were accidental, either through unintentional cross-pollination or stray seed, but once he found that they were round-up resistant, he actively worked to integrate the rr the genotype into his own populations. He probably just didn't feel like he was doing anything wrong.

    Small-time seed producers have done exactly the same sort thing with non-GMO germplasm from, e.g., Pioneer Hi-Bred for decades. They'd buy and plant a bag of hybrid seed, and look through the field for accidental selfs (plants produced by accidental self-pollination due to incomplete detasseling during hybrid production) to steal their inbreds from their female heterotic lines. That is just as illegal as what Schmeiser did, but you don't really hear about those guys being busted and completely ruined because Pioneer isn't run by the same type of raging pricks as the guys at Monsanto.

    [1] http://www.cooperativeresearch.org/context.jsp?item=gm-54 - "Monsanto argues that in spite of Schmeiser's claims that he did not use Roundup on his crops in 1998, there is no evidence that he used Muster and Assure herbicides as claimed. Furthermore, Monsanto provides evidence that Schmeiser purchased 720 liters of Roundup in 1998."

    [2] http://scc.lexum.umontreal.ca/en/2004/2004scc34/2004scc34.html - Schmeiser never purchased Roundup Ready Canola nor did he obtain a licence to plant it. Yet, in 1998, tests revealed that 95 to 98 percent of his 1,000 acres of canola crop was made up of Roundup Ready plants. ... The trial judge found that "none of the suggested sources [proposed by Schmeiser] could reasonably explain the concentration or extent of Roundup Ready canola of a commercial quality" ultimately present in Schmeiser's crop."
