Oh gee, if it's not the return of the guy who can't take "yes" for an answer.
You never before conceded wrt the Purdue link. You never said anything like "yes". You seem to think we can read your muddled thoughts and non-sense terminology and make sense of it.
To the argument- what EXACTLY did you mean when you cited the Purdue paper ? That we should hate Monsanto since some weeds are developing resistance ? I can impute no relevant meaning to your Purdue citation. It's not part of a coherent argument.
Now I'm not asking you to magically know what was meant but,
Good - now extend that thinking to your "can't take yes" comment when you never conceded and when the posting point seems at best a red-herring argument.
There is no honest reading of that as meaning "contains the genes from Monsanto's GM crops." So you're still going into your own flights of fantasy in interpreting it as HGT.
"GM" means "genetically modified" in this context and the only "resistance" discussed int the citation is round-up resistance, where Monsanto is the sole originator of that GMO genetics. So yes a very honest interpretation is that you were referring to GM from Monsanto in weeds. There ar no flights of
fancy involved - but you need a grounding is use of language.
2. again, it's coming right after a sentence where I said it does _NOT_ contain the Monsanto genes. How dishonest _do_ you need to be to spin two words into... meaning exactly what the sentence before said is not the case? Shouldn't that have tipped you off a bit?
That's not what you said in post#71. You agreed that HGT wasn't rampant and suggested "
mutation" (a term that includes GM) as the cause. Perhaps you meant natural selection, since there is NO EVIDENCE OF MUTATION, either naturally occurring or human-devised by GMO related to these weeds. Even your Purdue paper misuses the term mutation (one occurrence), but states the cause is pressure selection of a rare phenotype, NOT MUTATION.
You again lack a basic understanding of the issue and misused language, then you expect others to understand you "actual thoughts" through a sea of errornous posts and incorrect language.
Basically shouldn't you ask what it means, instead of assigning it your own, totally fantasy meaning?
I have asked, and still you refuse to help make any sense of why that Purdue citation is relevant to hating Monsanto.
Yes, do go back and actually read my posts. I never claimed "during feeding". Your filling in that part is the very definition of a strawman.
I asked for a reference and in #71 you supplied a Nature:Biotech article that ONLY tested the hypothesis in the gut, stating transfr did not occur. If you want to make a different argument, cite your evidence.

1/ You never said any such thing.
2/ Call for evidence for your "same end result" claim.
Cross pollination is only same-species gene transfer. That's vastly different from HGT where there are no boundaries for your "plasmids, plasmids spreading everywhere" fear mongering.
So for example we introduce Bt corn and perhaps have already crossed with wild maize of central America. Your alarmist fear is that we are going to wipe out European corn borer moths which predate on about 200 plant species - nearly all of which have no agricultural value ? Making one entire plant species out of ~200 poisonous to EuroCornBorer is VASTLY DIFFERENT from your alarmist case that would imply the eventually every higher plant would carry Bt genes.
Not the "same end result" at all. We are not eradicating any pest species that predates on Bt crops, unless it predates only on those few crop species (no cases in evidence). Instead we are reducing the pest population just a bit farther than expected. Your claim is entirely different.
Yes pollinating Bt crops into wild co-species has an foreseen impact and is dangeous. But to be fair - Euro CornBorers never hit maize till the late 1700s. Pushing these species off of the human crop species (even species-wide including wild members) doesn't mean they won't survive and may cause an increase in some competing species that was previously more dominant.
To clarify,
/ I am not, and never have, suggested that field use of GMO is without grave concerns and potentially disastrous outcomes.
/ I am not suggesting the cross pollination of GMO crops to a wild member of a species is not dangerous. It is.
/ I have never suggested the HGT doesn't occur; just that current evidence is that it has only occurred rarely over geological time periods and primarily in single celled life. Not a topic for this thread but lager brewing yeast seems to be an example.
/ I
am stating that the danger involved in GMO cross-pollination is categorically different from your claims that plasmids are being transferred willy-nilly from higher plants to every other thing in the ecosphere without regard to species.
You know, since you asked me to point out a strawman, there we go.
I seriously suggest you find a source book on critical thinking and try to understand what a "strawman fallacy" is. I asked for evidence and so far YOUR ONLY SOURCE is solely about HGT in the gut. Your source concluded there was no evidence for HGT in the gut. If you want to make a different case, that HGT happens elsewhere, your more expansive claim that plasmids transfer every time a bell rings, then YOU must provide evidence for those other points. It's not my job in a debate to prove your evidenced claims are wrong. Burden of proof is on you.
I'm not sure what kind of confusion of mind would cause takíng that to mean "from plant to bacterium."
If plasmids don't transfer from higher plants to bacteria - then why are you bringing it up in a discussion of Monsanto/GMO in higher plants ? Either you do blivet that point OR you are making an incoherent red-herring argument about a problem that you now seem to admit doesn't happen.
It's double silly since the same message and in fact the very next sentence where I talked about those plasmids in gut bacteria, says... "the consensus is that they didn't get that from eating GM soy". So, really, how dishonest _do_ you need to be to accuse me of a claim that not only I didn't make, but I claimed to _not_ be the case?
Wrong. Your source ONLY studied HGT in the gut (no evidence found). I was responding your source citation. If you provide evidence of other HGT I can respond to that --- -HOWEVER, I insist you make some claim relevant to the current thread.
I see no way that
your points about pressure to select resistant weeds and plasmid transfer NOT occurring from higher plants to bacteria has any relevance unless your understanding of these things is very flawed. That's my working assumption based on the egregious errors your early posts, some of which you have later retracted.
Stop the feces flinging and ad hominem and state what you actually believe. This is my last response to your your points until you can provide your position with backing evidence.
But would it? Would we use as much Roundup without GM crops modified to resist it? Or would such a mutation be selected for faster without the, you know, selection pressure that makes it an advantage?
Again a silly use of language - THERE IS NO MUTATION INVOLVED IN RESISTANT WEEDS ! It's selection pressure of a natural phenotype. Still there is a good question here.
On crops Glyphosate(GP=RoundUp) is absorbed through a foliar spray, and acts as a competitive enzyme inhibitor on the the shikimic pathway; stunts growth and causes rapid kill with lower dose in rapidly growing plants. GP is not effective on pre-emergent plants. GP is most effective on young growing annuals, far less effective on mature plants in reproductive phase. The GMO crop GP resistance is conferred by a single gene controlling the enzyme secondary conformation. I don't know if the weed natural phenotype is also controlled by a single gene - but it's reasonably likely. If so (**ASSUMPTION NOTED**) then each plant is either fully resistant or not - no partial cases as in multifactorial bacterial resistance to antibiotics.
Before the GMO/GP-resistant seed, GP was used as a kill-all - often in two heavy doses - one 4+ weeks before planting and one, often after planting but pre-emergent stage. After the non-GMO crop emerged then GP was no longer useful, and other selective herbicides like 2,4-D for corn were used (kills dicots, doesn't touch monocots) for imperfect weed control.
Since GMO GP-resistant seed, then ag ppl still use a kill-all (often GP) before planting, but they can use lower-dose GP after the crop emerges and throughout the growing season AS-NEEDED (to certain limits) for (nearly) complete weed control.
(+)Less RoundUp per hectare is
required b/c we can spray after crops emerge and "hit" the weeds in growth phase when it requires a low dose. (-)More Roundup is actually used b/c everyone (practically) recognizes the advantage so more hectares are planted with such GMO seed. (-?)In practice more RoundUp ?may? be used since it is off/patent and a relatively cheap and effective "kill-all" for field prep.
Any use of GP creates selection pressure, but if the assumption is correct (single gene), then an effective light dose may provide less pressure in the marginal areas around the field with lighter dosing and more mature weeds, and greater selection pressure w/in the field where presumably the ag-person sprays before the weeds mature leaving (almost) only the GP-resistant plants. The net result is difficult to assess without field data.
Rotating to a non-GP kill-all(burndown) and then using lighter dose GpP after emergence would obviously allow less GP- selection pressure. In practice this isn't how GP-resistant crop fields have been managed.
So the main problem seems the ubiquity of GP/Roundup as the main herbicide for vast regions of the planet. If we rotated between several herbicides with GMO/GP-resistant crop then the selection pressure would be greatly alleviated.
Then stop making up nonsense and address what i actually wrote. Simple solution, really.
Even simpler - You can make a coherent statement of your position using common accurate language. So far you have failed repeatedly then you chide me for not understanding your confused thoughts, red-herring argumens and grossly inaccurate language. Quit flinging feces to cover your errors.
I'm perfectly willing to address a coherent statement of your position, but so far I have nothing to reply to except your incompetent arguments. Why was the Purdue paper relevant ? Why was the non-transfer of plasmids from higher plants to bacteria important to the topic ? Can you cite any evidence for your GMO-soy=>bacteria claim ? (Your paper does not support that point).
Why not scale back the ad hominem fallacies too ? You've made this unnecessarily personal and argumentative.
You seem to support Monsanto-hatred proposition but the reasons are extremely confused and confusing in no small part to your poor use of language and off-topic/tangential propositions.
