Agricultural Genetics: Agricultural genetics refers to how traits are inherited in crops or livestock. An example of a plant trait is the number of days it takes for an ear of corn to reach maturity, or harvest. An example of a livestock trait is how tall a cow is expected to grow in its first year of life.

How does genetic engineering help agriculture?

Agriculture: The field of agriculture too greatly benefits from genetic engineering which has improved the genetic fitness of various plant species. The common benefits are increase in the efficiency of photosynthesis, increasing the resistance of the plant to salinity, drought and viruses and also reducing the plant’s need for a nitrogen fertilizer. The latest research at Cornell University is to map the ‘Oat’ crop so that extra nutrients can be added to the sequence and the make the crop healthier. Similar research is done with the ‘Soya’ crop as well.

Why are genetically modified crops important?

Genetically modified (GM) crops have many potential advantages in terms of raising agricultural productivity and reducing the need for (environmentally harmful) pesticides. They might also pose hazards to human health, from toxicity and increased risk of allergies, for example. However, particularly in Europe, regulations designed to ensure adequate safety of GM technologies may go too far.

What are the benefits of GM crops?

Second-generation GM crops involve enhanced quality traits, such as higher nutrient content . “Golden Rice,” one of the very first GM crops, is biofortified to address vitamin A deficiency, a common condition in developing countries that leads to blindness and entails higher rates of child mortality and infectious diseases. Other biofortification projects include corn, sorghum, cassava, and banana plants, with enhanced minerals and vitamins. Widespread production and consumption of biofortified staple crops could improve health outcomes and provide economic benefits in a very cost-effective way, especially in rural areas of developing countries. A recent simulation shows that Golden Rice could reduce health problems associated with vitamin A deficiency by up to 60 percent in rice-eating populations.

Why are Bt crops beneficial?

Health benefits result from reduced pesticide exposure for farmers and rural laborers and lower pesticide residues for consumers. Where Bt crops have been grown in developing countries, the technology appears to often generate employment, because more workers are needed to harvest the significantly higher yields.

What are some examples of GM crops?

So-called first-generation GM crops have improved traits. Herbicide-resistant soybeans and corn ( maize), for example, can be “weeded” with herbicides that are more effective, less toxic, and cheaper than the alternatives.

Reduced mechanical weeding helps prevent the loss of topsoil.

Does GM technology help agrobiodiversity?

Unexpected risks have not materialized so far, and those risks that do exist seem to be manageable. There is even evidence that GM technology can contribute to the preservation of agrobiodiversity, because the new traits can be inserted into local heirloom varieties.

Why is gene editing important in agriculture?

“In agriculture, gene editing is an enabling tool, supporting rather than supplanting, the fundamentals of plant breeding.” Gene editing is being used to develop plants that are thriftier users of water, support carbon capture, and are healthier to eat , said Chou.

Does the USDA regulate GE livestock?

Just before leaving office, the Trump administration pushed through an interdepartmental memorandum allowing the USDA to regulate food-bearing GE livestock while the FDA would remain in charge of other types of GE animals. Some lawmakers at the House Agriculture subcommittee hearing said the memorandum of understanding should be the foundation for federal regulation of GE livestock. Farm groups expect the USDA would be quicker to act on requests for approval.
