Hidden Viral Gene Discovered In GMO Crops

Jeremiah Cornelius writes "Researchers with the European Food Safety Authority discovered variants of the Cauliflower mosaic virus 35S in the most widely harvested varieties of genetically-modified crops, including Monsanto's RoundupReady Soy and Maze. According to the researchers, Podevin and du Jardin, the particular 'Gene VI' is responsible for a number of possible consequences that could affect human health, including inhibition of RNA silencing and production of proteins with known toxicity. The EFSA is endorsing 'retrospective risk assessment' of CaMV promoter and its Gene VI sequences — in an attempt to give it a clean bill of health. It is unknown if the presence of the hidden viral genes were the result of laboratory contamination or a possible recombinant product of the resultant organism. There are serious implications for the production of GMO for foodstuffs, given either possibility."

Not a virologist, but your response doesn't sound kosher. I don't see anywhere in your references, or any scientific citation linked by anyone at this site, anything at all to suggest that Gene VI insertion was at all Intentional.
  I somehow doubt that it is...but, of course, that would make transgenic technology far less precise than biotechnologist would love people to believe--
  which it is not.

Anyone making an analogy that we have been ingesting CaMV with veggies all along, so it must be safe--is drinking Cool Aid, We certainly weren't ingesting Gene VI in a transgenic crop carrying antibiotic resistance markers, EPSPS's, Bt, and random superfluous other pieces of DNA

  Gene VI isn't just a simple protein; it has multiple functions. Since Gene VI alters RNA silencing and transactivates (http://www.pnas.org/content/86/23/9203.full.pdf) the products of each individual transgenic crop are unpredictable and unknown--could be mutant proteins, toxins, allergens or be harmless. No one knows. And anyone who tells you that they can rule out a food allergy by doing a bioinformatics search for protein homology, has never once worked with a food allergy patient, because the inconvenient truth is that the gold standard of food allergy diagnosis is a placebo controlled blinded food trial... in real life. There are no in vitro tests or homology tests that are precise enough to predict food allergy..... which is why each transgenic crop needs to be uniquely labeled with some sort of a code enabling tracing it to its specific genetic modification.

Quite, though I'm not convinced by the first link's suggestion that this could be a human health issue. As a scientist I've got to say it's not a great article, there's a rather obvious attempt to shoe horn a health scare into the analysis, to say nothing of smearing a regulatory body. (The latter in spite of a full public disclosure.)

As for the substance of the science. Yes, gene VI is toxic to plants but it's toxic when expressed inside a cell, so while it may be a danger to an infected plant it's got serious hurdles to leap before it gets expressed in a mammalian cell. I'd also note that while ribosomes are highly conserved, plant and mammalian ribosomes are not identical, so even if the protein was expressed in a human cell it's by no means certain to be functional. Moreover, it appears this isn't even the full length Gene VI, so it would by no means be functional even in plants.

At most there's a risk to the GM crop in the form of a reduced viral resistance, that's a threat to Monsanto's bottom line more than anything else.

On the whole I'm not impressed with the editorial commentary by Latham and Wilson, there's more than a whiff of axe grinding and self promotion. "Independent science news is clearly a misnomer". I hope they've written this letter to the journal in question, rather than jeering from the sidelines.

Its known and expected that P35S would be present.

It is only supposed to be present in the lab, the actual crop you grown isn't supposed to have it. They use it during development only.

So again, nothing that might be been produced (but in fact have not been seen - hence "putative") by this gene's presence was found.

... in some databases. It is not certified for human consumption, and they are not scrambling to get that certification. So what TFA is saying is that on paper it looks okay but needs proper testing to determine if that is in fact the case.

Monsanto screwed up big time. They put something in our food that isn't known to be safe and that wasn't supposed to be there. The proper thing would be to destroy all affected crops and produce, but that would be expensive and Monsanto would have to pay vast compensation so instead they are just hoping that it turns out to be safe, or if not that they can bribe the relevant people.
