Monsanto takes organic corn, alters this to resist disease or drought. They then file a patent on this as this corn as well as all corn grown from this is their property. Now if the FDA says that nicotine is still tobacco because it came from tobacco, and is legally still tobacco, that corn seed which has been altered can now be said to still be corn seed if harvested from the plant the farmer grew after purchasing the parent seed. From my understanding this kind of "property rights" also reaches into the medical/bio/pharmaceutical industry as it pertains to human genes.
Monsanto is a truly evil corporation that wants to patent life and own the rights to it. They produce terminator seed, which is single use, and the farmer has to buy new seed every planting, giving Monsanto control of food. They also patented a pig gene, then went after a farmer in France suing him because they said his pigs had their patented gene. Just try and prove they dont! They are able to do this since the Uruguay round of GAT was passed, which allows corporations to patent life forms. A very dangerous and frightening development that could easily lead to global enslavement to transnational corporations controlling all food and implementing a global digital currency and imposing global fascism.
