On Sunday there was considerable confusion about the alleged "GMO" grass that killed cattle. Turns out it was not GMO grass at all, but a hybrid. I received many inquiries about the difference between a GMO and a hybrid, as the latter sounded truly freaky and much more invasive than any frankenfood.
While hybrids are not the technology we usually think of with the terms genetic modification or genetic engineering, it is just that-- humans manipulating plants by modifying the genes of an organism toward crop improvement. No lab needed, just cross two sexually compatible plants that are different! The next generation has literally tens of thousands of new gene variants, and maybe new genes, that are different from the parents.
So let's scrap the pedestrian term GMOs and work with something more precise: transgenic. This means that the plants contain a gene inserted using recombinant DNA technology.
To clarify the issue on Sunday I slammed a table together that contrasted transgenic technology against other methods of plant improvement. A look at the table reveals that all are methods of genetic modification, and everything we eat is truly a genetically modified organism, especially when compared to wild, ancient antecedents.
Since then, I've enjoyed feedback from colleagues and readers, and did a little thinking and googling. Here is the new and improved table:

Particularly, please compare:
1. How many genes are transferred.
2. If we know where transferred or affected genes are located
3. If we know what transferred or affected genes do
4 If genes can be used from one species to another
5. If plant products are acceptable for organic cultivation
6. If laws are pending to label the products
7. How long it takes to make an improved plant product
Now honestly answer these questions:
1. Which technology is most precise?
2. Which technology is best understood?
3. Did you realize that humans have intervened to create so many common foods?
4. Did you know that you regularly consumed so many genetically altered products?
5. Isn't it amazing that humans just implement nature's own tools to improve plants?
I hope this helps your understanding. Thanks to everyone that offered such great feedback. Maybe together we can share an honest discussion to take the franken out of frankenfood, and use the best available safe and proven technologies to shape the future of food.

Click on it for the larger version. Take a look at the methods used to improve plants by manipulating their genes. Some of these methods have been in place for 20,000 years.

For example, I believe strawberries have a bit more than 30K genes, so obviously it makes a difference if we make a claim regarding how many genes are affected.
Part of the problem I have with this type of comparison is that it is almost too simplistically made, because it fails to take into account that many of the other methods by which plant genetics have been modified were also done in ignorance. It is simply the long history of their role as food that has overcome any bias.
I personally feel that ANY modifications should always be subject to testing, verification, etc. So it isn't a matter of singling out GMO's, since clearly any modification has the potential to cause problems [i.e. consider the hybrid grass]. So, I don't see that as actually answering any questions. Now, if the point is that new hybrids are not subject to testing, then that's an issue that is certainly legitimately raised.
I don't agree that it is relevant to raise the issue of plants that were hybridized 20,000 years ago. They weren't done scientifically and it is largely the good fortune of our ancestors that they have done no significant harm. However, it is also legitimate to question whether some of these plants are responsible for certainly food allergies in individuals that may lack a tolerance for some of these variations.
All in all, it is quite a complex issue and there are numerous ways in which data can be interpreted or "spun". My personal view is that it doesn't appear to be a particularly effective technology at this point compared to alternatives that are also currently on the market. I'm also a bit suspicious at the intense desire to sell these products to people that clearly don't need them.
While they may be quite useful in difficult areas for farming and in areas where starvation is a problem, I fail to see why issues like the labeling laws proposed in California should make a difference to such usage. In short, it simply appears that we're being marketed to in a quite aggressive manner and like most salesmen that get too pushy ... people push back.
