(2,117 posts)monsanto loving weirdo-
So this virus gene, which is naturally occurring, has been demonstrated to cause problems?
The author of the OP and the article he quoted are creating a problem that does not exist.
The OP is quoting in internet article citing a pretty much benign literature review combined with a weak statistical analysis that says a scenario exists that a virus -- that already exists in nature -- might somehow become expressed in GMO foods if all the stars align
Exactly!!! The problem with Monsanto is their business practices, not the science.
You didn't read the article. Start over.
I didn't get past the "previously undiscovered virus". That's bullshit. You didn't read any of it.
Nice try. The virus in question is the Cauliflower mosaic.
Again: go to the OP. Click the link to the article. Then click the link to the original scientific publication. Then, quote for me where they say that the virus was previously undiscovered.
Off you go again, despite being corrected about this further up thread.
Ok. Quote it right here.
Read the damned article. Educate yourself.
I quoted the scientific article upon which the OP was based as saying that it is a well known naturally occurring virus.
...
hmmm, that is really weird, the words nature, natural, OR naturally DO NOT APPEAR in the article, so how did you quote that?
oh, right, you didn't even paste a quote or link, YOU MADE IT UP
do you see how that is just a huge pile of BS? EXTRA obnoxious, as you are demanding evidence from something u haven't read yourself?
The product of gene VI is a multifunctional protein (P6,
62 kDa) that harbours nuclear targeting and export signals15 and
ssRNA-, dsRNA- and protein-binding domains. Considerable
effort has been devoted to determine the various functions of P6
(Fig. 1).12,16-18
In this article, we discuss
the possible consequences of the overlap between gene VI and
the 35S promoter, when variants of this promoter are introduced
into plant nuclear genomes using stable transformation technology.
The P6 protein that
lacks domain D1 localizes exclusively to the nucleus, because
D1 contains residues that are required for P6-P6 intermolecular
interactions and viroplasm formation.15 At least one of P6s
nuclear functions is to suppress RNA silencing,32
We believe that if P35S is
embedded in a transformation construct with another gene cassette
at its 5' flank, it is unlikely that the partial gene VI will
be transcribed. In contrast, when the P35S is inserted adjacent
to plant genomic DNA, transcription from an endogenous plant
promoter might take place and create a chimeric protein that contains
part of P6.

When a segment of the CaMV genome bearing gene VI is transferred to tobacco plants by the Agrobacterium tumefaciens Ti plasmid, the resulting transgenic plants display viral-like symptoms. Symptoms produced by the DNA from two different viral isolates (CaMV Cabb B-JI and CM1841) were distinct-symptoms from the first were mosaic-like, whereas the other caused uniform bleaching of leaves. That gene VI was responsible for the symptomatic phenotype was demonstrated by showing that symptom production was blocked by deletions and by a frame-shifting linker mutation in gene VI. Furthermore, in primary transformants, there was a strict correlation between the appearance of symptoms and the presence of gene VI product, P(66), detected by immunoblots. Hence, a protein encoded by the CaMV genome produces viral-like symptoms in transgenic tobacco plants.
