    Oct 13, 2003 · Corn is one of humankind's earliest innovations. It was domesticated 10,000 years ago when humans learned to cross-pollinate plants and slowly turned a scraggly nondescript grass called teosinte into plump, productive modern corn . As needs change, so does plant breeding.

    • Bt Delta Endotoxin
    • Genetic Modification
    • FDA Approval

    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...

    Introduced in the mid-1990s, genetically modified (GMO) seeds now produce nearly 90 percent of the field corn in the United States (along with more than 90 percent of the soy and canola). Unlike hybridized plants, which are ­created through cross-pollination, genetically modified plants have strands of DNA added to achieve desired characteristics.

  6. Nov 04, 2019 · The world’s most widely planted GM crops, including soybean, corn, and cotton, were created with a few relatively simple genetic tweaks. By adding a single gene from bacteria to certain crop...
