Oct 13, 2003 · As pollen and seeds move in the environment, they can transmit genetic traits to nearby crops or wild relatives. Many self-pollinating crops, such as wheat, barley, and potatoes, have a low frequency of gene flow, but the more promiscuous, such as sugar beets and corn, merit greater concern.

The Bt delta endotoxin was selected because it is highly effective at controlling Lepidoptera larvae, caterpillars. It is during the larval stage when most of the damage by European corn borer occurs. The protein is very selective, generally not harming insects in other orders (such as beetles, flies, bees and wasps). For this reason, GMOs that have the Bt gene are compatible with biological control programs because they harm insect predators and parasitoids much less than broad-spectrum inse...
Do Bt-corn hybrids differ only in that they possess the genetic code to produce the Bt protein? Not exactly. To add a trait to a crop plant, the gene must be inserted along with some additional genetic material. This additional genetic material includes a promoter sequence that, in part, determines how the new trait is expressed in the plant. For example, the promoter may cause to protein to be expressed in certain parts of the plants or only during a particular period of time. There is a mar...
Federal food law requires premarket approval for food additives, whether or not they are the products of biotechnology. FDA treats substances added to food products through recombinant DNA techniques as food additives if they are significantly different in structure, function or amount than substances currently found in food. However, if a new food product developed through biotechnology does not contain substances that are significantly different from those already in the diet, it does not r...
Oct 31, 2018 · The GMO potato has been engineered through a method of gene silencing called RNA interference (RNAi). This genetic engineering technique results in a potato that hides the symptoms of blackspot bruising rather than preventing it.
Oct 22, 2018 · The Ppo5 enzyme usually causes potatoes to brown or blacken when cut or bruised, but when the Ppo5 gene is silenced in the GMO potato, the enzyme is absent and discoloration does not occur. The Asn1 enzyme is responsible for synthesizing the amino acid asparagine, but again, when the Asn1 gene is silenced, far lower levels of asparagine are ...

Nov 08, 2018 · The genetically modified Innate potato was approved by the USDA in 2014. The “Innate” potato is a group of potato varieties that have had the same genetic alterations applied using a new form of genetic engineering known as RNA interference (RNAi). Five different potato varieties have been transformed, including the Ranger Russet, Russet Burbank, and Atlantic potatoes.
Corn, however, can be grown for a number of different purposes. Field corn, when genetically modified, could provide livestock with better feed. Corn that is grown for ethanol production could produce a higher overall yield. For the corn we eat, it could be grown to taste better. 3. It offers a longer shelf life without preservatives.
Last week the European Commission approved cultivation and processing of the genetically modified starch potato Amflora. The request for authorisation was submitted by Amflora's developer BASF in August 1996, more than 13 years ago! In North America, currently no genetically modified potatoes are commercially grown. But the GM potato has already a colorful history in the US and Canada
