some mutated-food safety refs

[Nathan McCorkle]

I really couldn't find too much at all on the mutated foods...
(http://en.wikipedia.org/wiki/Mutation_breeding)

Has anyone seen a list of human food allergens and toxins anywhere? Something
that could be used as an panel of assays on the mutants. Seems like
the nightshade chemicals might be an easy marker to test a bunch of
varieties of tomatos and potatoes.


Microarray analyses reveal that plant mutagenesis may induce more
transcriptomic changes than transgene insertion
"Finally, we believe that safety assessment of improved plant
varieties should be carried out on a case-by-case basis and not simply
restricted to foods obtained through genetic engineering."

Are Mutations in Genetically Modified Plants Dangerous?
"One could react with a proposal to put also plants from induced
mutations under strict safety regulations. This would make sense only
if the mentioned 2543 varieties would have induced more frequently
biosafety problems then varieties from cross breeding. However, we are
not aware of any biosafety problem caused by an induced mutation of a
released variety or by an induced translocation. Apparently, the
common thorough evaluation of induced mutants at the phenotypic level
by the breeders suffices."

Bump.

If no one here has direct input/feedback, does anyone know some environmentalists/activists/GMO-haters that might get excited enough about the lack of info on this stuff?

Interesting stuff indeed. 

Where there is a significant flower industry, polyploid induction using colchicine has been a practice and I guess for some seedless or larger fruit varieties as well. I was told oryzalin was much safer to handle than colchicine, but that was just a statement from a TA that was teaching a course in orchidology. 

I don't think we need 'referees' so to speak; but we need good, mindful (smaller distribution) practices for food production just as there are certain safety recommendations for DIY labs :D 

Just because there maybe endogenous toxins created by these organisms doesn't mean they are any safer than the food we eat that receives an exogenous toxicant bath (and which 'no-till' GMO farming enables more and more of). 

A lot of the 'GMO hate talk' is due to practices of large biotech companies (Monsanto, Syngenta, BASF, Dow, DuPont, Pioneer, Bayer, . . . ) poisoning wells with atrazine and not cleaning it up, putting out bogus scientific studies, using a shit-ton of fuel to grow subsidized corn to make fuel, generally unsustainable agronomic practices, pressing legal action against small farmer's for the company's own genetic pollution, etc. (Not going to get into these companies' involvement in the military-industrial complex and wars)

And because some people have an innate fear of technology I suspect. Luddites. 

 It is hard to find the older varieties of papaya in Hawaii such as Solo or Strawberry that are free of the transgenic gene. When the 'Rainbow' papaya was released, markets were flooded with it. Japan had a ban on GMO importation so that market was temporarily lost, but has since recovered. To boot, the 'rainbow' papaya, in my opinion tastes like cardboard compared to many of the other varieties. 

A success? Maybe it saved our papaya industry but probably not. I can't seem to find it, but there is a study out of the Philippines where they had bred ringspot resistant C. papaya using traditional methods at a greatly reduced cost to transgenic modification.
