    This article is quite typical of the conceptual problem that many people still have with breeding versus genetic "manipulation". Both methods are means to the same end, ergo the introduction of desired genes or variations thereof into an organism. Breeding takes longer and cannot be controlled to the same extent. And don't start about the dangers of vectors, unwanted integration and crap like that. Nature does that every single minute (ever heard of transposons?) and nobody is complaining about that. So, "Frankenfood"? I think not.

      Yes, natural transposons among other things are suspected spreading genes for antibiotic resistance in bacteria.

      In fact it is theorized that longterm use of antibiotics causes natural good bacteria found in the body that are selected for antibody resistance to pass this resistance on to infectious disease bacteria in the body through transposons.

      Transposons are natural . . . but that doesn't mean that they don't cause problems. Additionally transposons in multicellular organisms are limited to the same species and are subject to natural selection before a large population is released to the environment. This is a natural buffer that limits the ability of transposons to maniplulate a species' genotype. GM foods are not subject to these natural limits on transposons.

      Laboratory GM is not the same as the effect of transposons in nature. To say otherwise suggests a gross misunderstanding of transposons.

      Additionally, breeding is not the introduction of desired genes or variations thereof into an organism. Breeding does not introduce genes into a population. It also does not introduce variations of the gene into the population. This is the falacy that many GM fans seem to believe. They are convinced that breeding somehow creates genes or modifies them . . . this is absolutely untrue.

      Breeding selects for desirable genes that already exist in the population. Genetic modification introduces desired genes or variations thereof. Breeding and introducing genes into a population are not at all the same thing

    How Smart Breeding Works

    The mission: Develop rice that's resistant to bacterial blight and will thrive around the globe.

    SEARCH Food scientists scour the rice gene bank, consisting of 84,000 seed types, in search of varieties with blight immunity.

    INSERT MARKER Scientists extract DNA from selected varieties and tag the blight-immunity gene - previously identified by researchers - with a chemical dye.

    CROSSBREED A network of researchers around the world cross disease-resistant varieties with thousands of local versions. With some plants, this means merely putting two varieties in a room. Self-pollinating rice requires manual pollen insertion.

    ANALYZE The offspring are analyzed to detect the presence of the immunity gene. Those containing the gene are planted in a field.

    TEST Mature plants are exposed to bacterial blight to confirm resistance. Those that don't die, and maintain desired traits from the local variety, are distributed. Unless

    REPEAT Sometimes, the process reveals several genes responsible for a trait. Three genes confer resistance to different blight strains. In such cases, breeders repeat the crossbreeding until all genes are turned on.

    END RESULT A rice plant with broad resistance to bacterial blight that will thrive in local conditions.

    Though this is technically a form of genetic engineering, it is not a comprehensive description.

    What you describe is selective breeding . . . it has existed for a long time. But this is using naturally occuring genes in the genepool and selecting for them through mating within a species or closely related species.

    Taking a gene from a firefly and implanting it in a tobacco plant to create glowing tobacco, or creating a brand new modified gene that does not exist in the natural gene pool is also genetic engineering. The statement

    The difference is that now, we have the advantage of looking under the hood at the genes themselves. This new data gives farmers and geneticists an unprecendented level of control in selecting for certain traits.

    is true but not comprehensive. It ignore the concerns of the alarmists.

    Selective breeding has nothing to do with the transgenic techgniques used in GM crops. It makes me so mad when GM apologists offer up this tired and inaccurate canard.

    When you crossbreed tomato strains, all the genes in the hybrid were in the tomato gene originally; the same cannot be said of transgenic grops. (Barring the small possibility of a mutation, or of genetic transfer via viral infection - but in most cases these will kill the plant, or render it less likely to reproduce.)

    Also the genes in the hybrid are (to simplify) "well attached" to the organism's genome; in GM organisms, the transgenic part is "loose". This increases the chance of it migrating into a virus, and we don't know the implications of this "looseness" over generations of reproduction.

    GM crops are nothing like selective breeding. But there is a huge problem with the way we apply selective breeding, and GM crops suffer from this also: we're losing the genetic diversity of our food crops, as heirloom varieties are displaced.

It is used to boost milk output, and the FDA says that it is safe. As a matter of fact, there is no test that can distinguish between the milk of treated and untreated cows. Of course, these farmers were proud of their little hippy dairy, and righfully so. They made a good local product, delivered fresh, for a fair price. They decided to promote the fact that they did it all without hormones. So on their bottles, it says: "We do not use RBGH on our cows". That's it. Nothing saying that RGBH is bad, or that it will turn you into a tentacled monster. What does Monsanto do? They launch a legal campaign to make it illegal to state that you do not use RBGH. They claim that by pointing out that it is not used, you are claiming that it is bad. Now call me crazy, but I believe that I have a right to know what goes into my food.

    It doesn't have anything to do with evolution. Evolution works by natural selection. The breeding of crop plants works by "assisted selection": people set out to select for specific traits that make the plant more attractive as food.

    The traits that promote plant survival aren't necessarily the traits that promote plants people want to eat.

    In addition, as explained in the article, we have been breeding these things for years, essentially selecting for the traits we want without regard to whether they are good for plant survival. The trait we selected for decreases insect resistance? No problem, we'll just add more pesticides to the crops.

    Remember this is just a basic overview.

    Now down to the real stuff, an article done in 1993 testing the very statement you just made about genetic instability in tomatoes: Abstract Below:

    "Ac-induced instability at the Xanthophyllic locus of tomato.

    Peterson PW, Yoder JI.

    Department of Vegetable Crops, University of California, Davis 95616.

    To detect genomic instability caused by Ac elements in transgenic tomatoes, we used the incompletely dominant mutation Xanthophyllic-1 (Xa-1) as a whole plant marker gene. Xa-1 is located on chromosome 10 and in the heterozygote state causes leaves to be yellow. Transgenic Ac-containing tomato plants which differed in the location and number of their Ac elements were crossed to Xa-1 tester lines and F1 progeny were scored for aberrant somatic sectoring. Of 800 test and control F1 progeny screened, only four plants had aberrantly high levels of somatic sectors. Three of the plants had twin sectors consisting of green tissue adjacent to white tissue, and the other had twin sectors comprised of green tissue adjacent to tissue more yellow than the heterozygote background. Sectoring was inherited and the two sectoring phenotypes mapped to opposite homologs of chromosome 10; the green/yellow sectoring phenotype mapped in coupling to Xa-1 while the green/white sectoring phenotype mapped in repulsion. The two sectoring phenotypes cosegregated with different single, non-rearranged Acs, and loss of these Acs from the genome corresponded to the loss of sectoring. Sectoring was still observed after transposition of the Ac to a new site which indicated that sectoring was not limited to a single locus. In both sectored lines, meiotic recombination of the sectoring Ac to the opposite homolog caused the phenotype to switch between the green/yellow and the green/white phenotypes. Thus the two different sectoring phenotypes arose from the same Ac-induced mechanism; the phenotype depended on which chromosome 10 homolog the Ac was on. We believe that the twin sectors resulted from chromosome breakage mediated by a single intact, transposition-competent Ac element."

    4 out of 800 plants showed abnormal F1 progeny. Thats exactly 0.5% of the F1 generation. Now lets look at mutation rates, polymerase that copies DNA is pretty good at what it does and at any single STR location, it is estimated that a mutation will occur only once every 500 'transmission-events' - or roughly 0.2% per generation. 0.5% to 0.2% could be statistically relevant but due to the selective resistant applied to the plants upon DNA insertion that is unlikley, in other words I disagree.

    Note, this doesn't mean that other disadvantges do not exist for trangenic plants but what the above poster stated makes no sense.

    Here are a couple meaningful dangers, just off the top of my head.

    1) Crossbreeding into non-GE crops.
    This is extremely common with wind-pollenated crops such as corn and other grasses. A recent example was a cross of a GE crop for feedstock crossing into corn for human consumption, was known to produce an allergic reaction in humans. This got into Taco Bell foods. Additionally, it is a pollutant to the gene pool, and the farmers and companies are not responsible for keeping it under control.

    2) Effects on the environment
    A recent GE corn, designed to resist insects, dropped pollen on nearby milkweed plants. The pollen was poisonous to insects and ended up wiping out the monarch butterfly population in that small area. It could end up an environmental nightmare, but the companies producing this have no idea of the impact. A plant could potentially end up contaminating all crops, especially if it grew as a weed and could outcompete all untainted crops. Pollen is tiny and potent, and can travel thousands of miles over wind or animals.

    3) Effects on others
    As stated, GE crops pollute the environment because they are not controlled. Produced in a sealed lab, it has little chance of escaping. But all GE crops should be viewed as potential pollution, simply because their pollen can blow into your yard, and contaminate your crops.

    4) Legal issues
    If your crops become contaminated through no fault of your own, it's very possible -- even likely -- that you'll have to destroy your crops for violating patents or pay license fees, or be basically shut down from legal suits. In other words, everytime a gene is spliced in, that food item is patented and any violation of that patent can be prosecuted. This violation can even happen if your plants happened to crossbreed and incorporate that gene. Intent is not figured into patents... if you invent something completely on your own that is patented, you lose. If you grow something without a license that's patented, you lose.

    5) Social issues
    Other issues are social, such as the painful idea of corporations owning the rights to grow food. But let's say you practice vegetarianism because you happen to believe in it (for whatever reason). What if GE tomatoes incorporate a fish gene? Is that tomato suddenly non-vegetarian? Let's say you know that GE tomatoes might have fish genes so you avoid them and look for items marked "organic". WHOA THERE... the corporations have lobbied congress to bastardize the concept of "organic" (to make it meaningless, basically allowing full use of pesticides, etc) and even pressed the FDA to disallow labelling things as organic or produced without pesticides. This last part is one of the worst things about patenting foodstuffs -- the corporations want their actions hidden, and will pay lobbiests millions to get laws passed protecting them from people that simply want to know what their eating.
