Every food crop on earth has been "genetically engineer" at some point to make it edible or more profitable to sell using traditional method sucha as selective breeding. However if you mean modified using genes directly added by humans then the list is still extensive. Wheat, corn and tomatoes have all been directly modified by human activities, many other plants have as well. Some times the modified plants can not be sold as food for humans, however it has been know to reach shelves anyways.

∙ 15y agoTomatoes have frog DNA spliced into their DNA so that they can be stored at cooler temperatures without freezing/going bad. If you think this is wrong, petition against it. The first genetically altered plant was tobacco. They successfully inserted fire-fly DNA into the plant so that it glowed at night. No marketable application but it was easy to verify that the splicing had taken place - as the plant glowed in the dark.

Why do cactus grow flowers?
Just the same as any other flowering plants. Plants adapt to their environment by evolution some cactus are plants adapted to dry conditions.
What are some benefits of genetically engineered crops?
It depends on how they are genetically engineered. The possibilities are almost endless (given time to research the idea) but there are 2 genetic modifications that seem to be most common. Making a crop easier to grow in harsher climates, or causing the crop to grow faster. There are also drawbacks, such as many genetically engineered crops having lower nutritional value, but scientists are constantly working on overcomming these problems, and most of the genetically engineered crops used today are free of these problems.
Can only bacteria be genitically engineered?
Not at all. There are many foods that you eat that have been genetically engineered to produce something better or faster than before.
Why is a genetically engineered canarypox virus being treated as a potential aids vaccine?
Because IT IS
A substance produced by genetically-engineered bacteria is?
Insulin - The Dude That's Friends With THE DUDE
Why do some people prefer to eat that are not genetically engineered?
People prefer to eat foods that are not genetically engineered because the long term effects of eating genetically engineered plants is unknown.

What characteristic is often genetically engineered in crop plants?
By far the characteristic that is most often genetically engineered into crop plants is resistance to herbicides, with engineering crops to produce a substance that kills insects into the plant itself a close second.
Plants are expected to be genetically engineered to have?
resistance to the elements (such as cold and hail) and pests. Also they're engineered to have a larger crop
Which characteristic is often genetically engineered into crop plants?
Better growth and bigger yeilds.
What do stores do to genetically engineered produce?
Stores label genetically engineered produce.
What is biopharming?
"Biopharming" is an experimental application of biotechnology in which plants are genetically engineered to produce pharmaceutical proteins and chemicals
What are the dangers of biotechnology?
The dangers would be that the genetically engineered plants and crops can become harmful to the environment and society.
What does GMO stand for?
GMO stands for a Genetically Modified Organism.
Do many stores refuse to sell genetically engineered produce?
not really. they do however label genetically engineered produce.
Why are enviromentalists concerned about the introduction of genetically engineered trees?
Genetically engineered trees decrease the biodiversity of natural resources
