Scientists are creating genetically altered foods that contain nutrients known to help fight disease or malnourishment, to improve human health , particularly in underdeveloped countries. An example of this is Golden Rice, which contains beta-carotene, the precursor for Vitamin A production in our bodies. People who eat the rice produce more Vitamin A, an essential nutrient lacking in the diets of the poor in Asian countries. Three genes, two from daffodils and one from a bacterium, capable of catalyzing four biochemical reactions, were cloned into rice to make it “golden.” The name comes from the color of the transgenic grain due to overexpression of beta-carotene, which gives carrots their orange color.

Society should be provided with a balanced view of the fundamentals of biotechnology and genetic engineering, the processes used in developing transgenic organisms, the types of genetic material used, and the benefits and risks of the new technology.

How has biotechnology improved crop productivity?

Biotechnology has helped to increase crop productivity by introducing such qualities as disease resistance and increased drought tolerance to the crops. Now, researchers can select genes for disease resistancefrom other species and transfer them to important crops. For example, researchers from the University of Hawaii and Cornell University developed two varieties of papaya resistant to papaya ringspot virus by transferring one of the virus’ genes to papaya to create resistance in the plants. Seeds of the two varieties, named ‘SunUp’ and ‘Rainbow’, have been distributed under licensing agreements to papaya growers since 1998. Further examples come from dry climates, where crops must use water as eciently as possible. Genes from naturally drought-resistant plants can be used to increase drought tolerance in many crop varieties.

Why do farmers use crop protection?

Farmers use crop-protection technologies because they provide cost-effective solutions to pest problems which, if left uncontrolled, would severely lower yields. As mentioned above, crops such as corn, cotton, and potato have been successfully transformed through genetic engineering to make a protein that kills certain insects when they feed on the plants. The protein is from the soil bacterium Bacillus thuringiensis, which has been used for decades as the active ingredient of some “natural” insecticides. In some cases, an effective transgenic crop-protection technology can control pests better and more cheaply than existing technologies. For example, with Bt engineered into a corn crop, the entire crop is resistant to certain pests, not just the part of the plant to which Bt insecticide has been applied.

What was the first food product derived from genetic engineering?

The first food product resulting from genetic engineering technology to receive regulatory approval, in 1990, was chymosin, an enzyme produced by genetically engineered bacteria. It replaces calf rennet in cheese-makingand is now used in 60 percent of all cheese manufactured. Its benefits include increased purity, a reliable supply,a 50 percent cost reduction, and high cheese yield eciency.

How does genetic engineering help?

Genetic engineering can result in improved keeping properties to make transport of fresh produce easier, giving consumersaccess to nutritionally valuable whole foods and preventing decay, damage, and loss of nutri•ents. Transgenic tomatoes with delayed softening can be vine-ripened and still be shipped without bruising. Research is under way to make similar modifications to broccoli, celery, carrots, melons, and raspberry. The shelf life of some processed foods such as peanuts has also been improved by using ingredients that have had their fatty acid profile modified.

How can flavor be altered?
