How genetic engineering is used in agriculture?

Answer 1

In the USA, there are at least three major ways that genetic engineering is used in agriculture that I know of. Probably the most well known: herbicide resistance such as Glyphosphate resistant has been genetically engineered into crops (beans, corn, for ex) so that farmers can then apply Glyphospate to fields, killing the nonresistant weeds. Another example - the gene that encodes the insecticidal crystal protein of Bacillusthuringiensis has been introduced into some crop plants to make these plants lethal to herbaceous insect pests. A third example - scientists have introduced genes that produce nutrients, such as carotene into staple foods such as rice. The first two applications are controversial, as evidence of herbicide and insecticidal resistance spreading to "weeds" has been confirmed.

Answer 2

Genetic engineering is used in agriculture to develop crops with desirable traits such as pest resistance, drought tolerance, and increased yield. This technology allows for more efficient and sustainable farming practices by reducing the need for pesticides and improving crop performance in challenging environments. Additionally, genetic engineering can help address food security and nutritional needs by producing crops with enhanced nutritional content.
