GMO Oranges? Altering a Fruit's DNA To Save It
biobricks writes "A New York Times story says the Florida orange crop is threatened by an incurable disease and traces the efforts of one company to insert a spinach gene in orange trees to fend it off. Not clear if consumers will go for it though." The article focuses on oranges, but touches on the larger world of GMO crop creation as well.
Nature has been genetically modifying fruit for millions of years. Genetic modifications can be good, bad, or some of each.
Just because something is "natural" doesn't mean it's good for you. Many natural things are quite deadly. Just because something is modified by humans doesn't mean it's bad for you. It might be! But you don't know that just because it's "genetically modified".
No. Cannot and Will Not go there.
Faster! Faster! Faster would be better!
Genetic modification of crops in a formal sense scares people for now. But, this is a young technology, and current genetic modifications are made, to a certain extent, blindly. While these modifications have known effects, they are also bound or at least potentially bound to have unknown effects as well. The reason, however, that these do not scare me so much is that this technology will only progress, and we will only gain a better understanding of how these modifications are affecting our crops. Hopefully, we can make decent decisions ab out regulating this in the mean time, but I think it won't be terribly long before we can make genetic modifications that are solely safe and hopefully better for consumers. In terms of the historical progression of agriculture, there has never been a time in human history that we have NOT modified the genes of our crops; only, we have done this through controlled abuse of the relatively quick and convenient evolution of crops given their short lifespan (new generations are quick to rise). Barely anything we eat today would be naturally occurring in actual nature. We designed these things to occur through comparatively (to GMO) crude methods. Bigger watermelons, redder strawberries, beefier wheat, or what have you. GMO could be the next step in this progression of healthy and nutritious foods IF done correctly. All the same, with knuckle-heads controlling the direction of GMO, it could have vastly different and unknown consequences. I'm simultaneously nervous and interested to see where it goes with a little more time.
Once you understand how commercial orange juice is made I guarantee you'll never want to drink it again.
Why don't they work on a cure for orange greening? If they don't know the nature of the disease, who's to say that in 10 years the new orange won't be susceptible to a new or mutated disease? And then where are we?
You know the kind that have been selectively bred over thousands of years and would never have happened by chance. The kind that are now grown in huge monocultures that are all susceptible to the same diseases like these oranges. I don't want people messing with my food!
The effect of a genetic modification depends on what was changed. Some genetic modifications have given clear and reasonable cause for concern. In the case of Monsanto's "Round-Up Ready" seeds, greater use of pesticides (Monsanto's "Round-Up") on crops is possible. Pesticide exposure is a serious risk for farm workers as well as the environment and a point of reasonable concern for consumers, though low-dose toxicology is tricky business. Another problematic modification is the addition of BT toxin genes to crops. Although, BT is approved for use in organic produce, the chronic low dose of BT toxin is a problem because it allows pests to evolve to become resistant to this useful compound more easily than would occur with occasional external application of higher doses. BT toxin resistance has already developed in India in response to crops incorporating the BT gene. https://en.wikipedia.org/wiki/Bacillus_thuringiensis It would be reasonable to expect more widespread resistance to occur with continued use of crops with BT genes.
The use of the spinach gene to give bacterial resistance to orange trees mentioned in the aricle does not have these issues. The article notes that this bacterial resistance gene is widespread, existing in variants in many plants and animals. Also, having orange trees with this gene would allow for reduced use of pesticides, which the article notes have tripled in response to the encroachment of the insect which carries the bacterium responsible for the destruction of the orange trees.
I would argue not for a ban on genetically modified organisms, but for careful scientific review on a case-by-case basis whether a modification carries a net benefit, not just on whether a particular crop is safe to consume. A serious problem with previous approvals is that they ignored effects like evolution of resistant organisms and incentives to use more pesticides.
As stated by others, this is a natural phenomenon and is only a problem for modern industrial agriculture practices, especially those based on the mass monocropping of a few select breeds to feed the world. Putting all of our eggs in a few baskets is just ignorant. An ecosystem requires diversity to survive.
This smells like a scheme to make GMO crops more acceptible to the public, suggesting only science can save the oranges and therefore we'll just have to get use to the idea of GMO crops, as if there were no other viable alternatives.
Here's an alternative - replace monocrop orchards with polyculture farms (i.e. food forest) that are based on the same principles of natural ecosystems. Their diversity is what has allowed them to survive just fine without human interaction for longer than we've been around to fuck up the works.
It might be worth it, after all, what's the point of having this knowledge and not use it.
Did you even read the article? The infection is all over the wold. Brazil, Iran, China, etc.
>"Florida orange crop is threatened by an incurable disease"
And perhaps that is because they plant millions of the same species/strain with no natural variation? Haven't we learned yet how bad that is?

“In all of cultivated citrus, there is no evidence of immunity,” the plant pathologist heading a National Research Council task force on the disease said.
Somebody has to speak for these oranges. You all got on this website for different reasons, but you all come to the same place. So now I’m asking more of you than I have before. Maybe all. Sure as I know anything I know this, they will try again. Maybe on another world, maybe on this very ground swept clean. A year from now, ten, they'll swing back to the belief that they can make oranges...better. And I do not hold to that. So no more running. I aim to misbehave.
tomorrow who's gonna fuss
No oranges.
The idiots that oppose protecting a worldwide food crop from certain extinction because they're scared of science ought be ignored flat out in this case.
I am a trained geneticist and have been involved in genetics/genomics research for more than 20 years. I can categorically assure you that this book is complete and utter nonsense; in this particular case the one-star reviews are bang on.
Quoth TFA:
“In all of cultivated citrus, there is no evidence of immunity,” the plant pathologist heading a National Research Council task force on the disease said.
Deal with it: there's no all-wise Mother Nature who has arranged for the perfect harmony of all beings. Species evolve taking advantage, in spite of, or in a mutual-benefit relationship with other; and then sometimes because the other simply isn't around. Previously isolated species may meet, and whole taxa may thrive or perish.
Citrus greening disease has been around for a century across species, and it's incurable. The alternatives are 1. eradicating the pathogen (good luck), 2. eradicating the vector (even harder, and craptons of pesticides are required), 3. making the vector immune (read: genetic manipulation), or 4. making the plant immune (again, genetic manipulation). Pick your poison.
This post contains no rudeness or derision of any kind. All arguments are friendly. Terms and exclusions may apply.
Not clear if consumers will go for it though.
Fortunately most of them will never know. :p
I agree with your point, but to be fair Round-Up (glyphosate) is an herbicide and not a pesticide. I know, sounds like semantics, but making good arguments but messing up the details makes your point less salient. Glyphosate is also one of the safest herbicides in wide spread use, numerous studies have shown little if any long term adverse side effects and while acute toxicity is a possibility it is extremely rare and almost certainly an issue of a accidental extreme exposure. Natural resistance to glyphosate is the REAL reason to not want it used so widely. It is an extremely useful herbicide and to apply it when MANY alternatives exist because it make life easier than those alternatives is poor agriculture.
Basically I agree with your points. My feeling, however, is that new GMO products should be treated the same as new drugs. One can argue that the controls should be tighter, as they expose more people to the change. Often the changes created by a new GMO organism are greater than the change in a new drug (which is often just tweaking to preserve patentability).
I think this means that I'm in favor of tighter controls on GMO organisms than you are, but I'm not sure, as I also favor looser controls on new drugs (than are officially in place...I'm not considering here that drugs tests are run by the people who will profit from finding them safe and effective).
I think we've pushed this "anyone can grow up to be president" thing too far.
Nonsense. Roundup Ready technology REDUCES pesticide use. Furthermore the active ingredient in RoundUp is perhaps the least toxic to mammals of any pesticide ever developed.

Key word: CULTIVATED.
Bet you there's plenty of wild citrus that is immune to this, given it's guaranteed to have wildly different DNA versus the mono-culture cloning of the same plant over and over again.

-><- no
are the real issue. If you plant 1000's of acres if one thing you are likely to have your crop wiped out by one disease that easily spreads. Use spacer crops to avoid spread of such diseases. I know it doesn't really fit with our ways of thinking but ... nature does it this way. Why not mimic it?
They may be evil moustache-twisting gene splicers, but they're not idiots. If there were a wild citrus species which was immune, they'd be mining it for genes.
"new and improperly tested food"
What the hell does that mean?
New GMO food is tested out the wazoo. Existing GMO food has been tested now by hundreds of millions of people with no ill effect.
The jury is in, has gone home, and written the tell-all book. GMO food is safe and it's madness not to support making food safer and healthier in this way.

replace monocrop orchards with polyculture farms
The ironic thing if scare-mongerers like you were not drumming up fear of GMO foods, every orchard would probably have many different varieties of even a single crop, each with a different GMO variant to test out some new flavor or ability.
GMO fears are what is leading to monoculture, because you are blocking scientific progress on any possible changes that can be made to food crops.

Round-Up (glyphosate) is an herbicide and not a pesticide
Herbicides are pesticides. Pesticide is a very broad term. You may be confusing it with insecticide.
Or they could, y'know, plant several varieties of orange trees to hedge against a narrow epidemic. Like, say, a parasite that his spinach really hard...
Ceci n'est pas une signature.
The problem with GMO is not the science of it, not the benefit of it, it is that GMO is driven by short term profit, plain and simple. If a company can splice in a beneficial trait for short term profit, they will do it. No questions.
The problem arises in not requiring or possibly even being able to conceive the mid or long term consequences.
An example is a story I read a few years ago... basically an ecosystem had collapsed because of the elimination of wolves. The strange part was that the system was collapsing because of the rivers running dry. An excerpt from Here
The chain of effects went roughly like this: No wolves meant that many more elk crowded onto inviting river and stream banks. A growing population of fat elk, in no danger of being turned into prey, gnawed down willow and aspen seedlings before they could mature. As the willows declined, so did beavers, which used the trees for food and building material. When beavers build dams and make ponds, they create wetland habitats for countless bugs, amphibians, fish, birds and plants, as well as slowing the flow of water and distributing it over broad areas. The consequences of their decline rippled across the land.
The point being, we are introducing unexpected consequences to a system that has come to balance over millions of years.
Its not the Oranges today we should worry about.. its the new breed of resultant pine trees in 20 years that kill all the butterflies and cause the grass on the plains to stop growing... wild example.. but did you really think exterminating wolves would make the rivers run dry?
There is a world of difference between selective breeding for desired traits and GMO technologies that insert foreign genetics.
I do not fail; I succeed at finding out what does not work.
Selective breeding of disease-resistant plants instead of monoculture of juice oranges.
I do not fail; I succeed at finding out what does not work.
Isn't that an oxymoron? Sort of like "we had to destroy the village in order to save it". Once altered it is no longer the same plant.

From your own citation [118]: "It may be that some Roundup Ready seed was carried to Mr. Schmeiser's field without his knowledge. Some such seed might have survived the winter to germinate in the spring of 1998. However, I am persuaded by evidence of Dr. Keith Downey, an expert witness appearing for the plaintiffs, that none of the suggested sources could reasonably explain the concentration or extent of Roundup Ready canola of a commercial quality evident from the results of tests on Schmeiser's crop. His view was supported in part by evidence of Dr. Barry Hertz, a mechanical engineer, whose evidence scientifically demonstrated the limited distance that canola seed blown from trucks in the road way could be expected to spread. I am persuaded on the basis of Dr. Downey's evidence that on a balance of probabilities none of the suggested possible sources of contamination of Schmeiser's crop was the basis for the substantial level of Roundup Ready canola growing in field number 2 in 1997."
In case it isn't clear: you can't be successfully sued for accidental gene transfer.
I can't tell be sure if this is wild bluster, trolling, or stupidity - but it's likely all three.
A similar situation occurred with the papaya ringspot virus threatening to devastate the papaya industry in Hawaii. However, in 1998, researchers developed a genetically modified papaya resistant to the virus, and this scientific development has been credited with saving Hawaii's papaya industry. Perhaps this offers some hope for a good outcome in using genetic modification to solve the problem of citrus greening.
"labeling the food" does nothing except enrich trial lawyers. So you protect yourself by labeling *every* food product with "contains GMOs".
Just like everything in California has a label on it saying this product has chemicals in known by the State of California to cause cancer.

Would a technological analogy to releasing GMO plants be releasing a (for profit) computer virus? We can't depend on an AVG environmental virus scanner or the for profit corporation that sold the GMO to repair our damaged environment after all of the oranges (or other species) are infected/damaged with genetic programming side effects.
Who does code reviews on GMO's???
new letter/phrase: hex-u means "www"
Suddenly! In 2013! At the height of public controversy over genetically modified food, the entire orange crop is affected by an incurable disease that can only be cured by genetic modification!
Aside from the fact that the incurable disease was cured, does anyone recognize pure bullshit any more?

So the little insects flew all the way across the Pacific Ocean?
Farmers have to buy new hybrid seed every year too. Are hybrid seed companies "monopolizing" food production too? Or is it simply that farmers like the properties of the hybrid plants, so they choose to buy seed every year?
-- Knowledge is power. -- Francis Bacon
current GMO is not at all aimed at diversity.
No, it is not, THAT IS MY POINT. It cannot be when everyone is so afraid of GMO that they pile regulation on top of regulation.
In reality right now, each and every farmer could be exploring GMO in their own crops, bringing about a variety and diversity of food products the like of which the world has never seen.
The reason most farms do not avail themselves of this diversity is short-term thinking
No, it's because grafting is an incredibly slow and time consuming process that is done one plant at a time.
And for some crops there is very little diversity in natural crops to graft with, GMO opens up a far vaster range of possibilities.
Real competition, ending farm subsidies to millionaires/billionares
That is so hilarious when the regulations making GMO so hard are the reason the large companies own farming now! Only they can afford the tremendous costs to make GMO hybrids that work best in the field.
You (and the rest of the GMO alarmists) are the ones supporting Monsanto.
"There is more worth loving than we have strength to love." - Brian Jay Stanley
Several studies have showed already that monsanto has lied about for example how the herbicides are not taken up by our intenstines.
Why am I not surprised that this comes from an AC, with no links whatsoever to provide proof?

" If there were a wild citrus species which was immune, they'd be mining it for genes."
Not necessarily. It'd cost a huge fortune to mount a global hunt for wild species with immunity. Cheaper to try to engineer it yourself.

Nobody disputes that. Small amounts of gene flow are expected and aren't a legal issue.
Not a whole field full. And remember that it was the "concentration or extent" that the judge was citing, not just that the RR trait showed up.
