^{Transgenics are genetically engineered organisms into which one or more genes from other species have been introduced. For example, transgenic corn grown in Spain contains a gene from the bacterium Bacillus thuringiensis. If you ever see or hear about genetically modified organisms (GMOs), they are also talking about transgenics.}

What kind of genes are used in transgenic crops and products?

^{The transgenic crops and foods currently on the market basically incorporate bacterial genes, but the possibilities are very broad. Research is being done with mouse genes in pigs, fish genes in tomatoes, human genes in rice and so on.}What kind of transgenic crops are there?
^{There are only a few: basically soybean, corn, cotton and rapeseed, which account for practically 100% of the area cultivated with GMOs worldwide.}]]> 2021-08-28 19:58:36 UTC https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702146342 Infographic-GM Crops melanyvargasr2000 https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702184075 2021-08-28 21:46:10 UTC https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702184075 melanyvargasr2000 https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702185213 What are the benefits of GMOs?

_{After more than a decade and a half of commercial cultivation, the biotechnology industry has not been able to demonstrate a single benefit of transgenics, neither in economic, environmental or health aspects.
It has been demonstrated that they do not have a higher yield, that the environmental impacts are serious (mainly due to the increased use of pesticides) and that the socioeconomic costs are high (due to the impossible coexistence with the organic sector and the lack of responsibility in the face of contamination).
There are also serious doubts about their cumulative and long-term effects on health.}
Transgenic crops under development are:_{- Virus resistant: potato, sweet potato, cassava, sugarcane, tomato, hemp, bean, grapevine, corn, citrus, peanut, melon, cabbage, wheat, zuchini, banana, chili.
- Bacteria resistant: rice, sugar cane, potato.
- Resistant to fungi: banana, strawberry, grapevine, wheat, pasture, soybean, rice, apple, tomato.
- Insect resistant: rice, apple, broccoli, potato, tomato, sorghum, cabbage.
- Drought tolerant: rice, alfalfa, sugar beet, potato, soybean, wheat.
- Frost tolerant: tomato, corn, alfalfa, potato, rice, canola.
- Higher nutrient use efficiency: rice.
- Herbicide tolerant: potato, tomato, wheat, rice, sugarcane}.

Golden rice
_{This is a type of rice to which the genes needed to produce beta carotene, the precursor of vitamin A, have been added. Golden rice is intended to provide vitamin A to populations that do not consume enough of this vitamin on a daily basis.}
_{It is estimated that around 500,000 children worldwide lose their eyesight each year due to this deficiency, which is particularly prevalent in Southeast Asia, where rice is a staple food. Although not yet commercially available, it is already being field-tested in several Asian countries. The Philippines has approved golden rice for direct consumption and processing, joining Australia, New Zealand and the United States, which have already affirmed its safety.}

Better oils
_{The list of crops with modifications in oil content includes those aimed at avoiding hydrogenation (high stearic, high oleic or low linolenic soybeans), incorporating omega 3 (in soybeans, canola and flax) and increasing vitamin E levels (in corn, soybeans and canola).}
Tomatoes with more lycopene

^{Lycopene is an antioxidant carotenoid that neutralizes the free radicals produced in the body that lead to cellular aging and the development of cardiovascular diseases and certain types of cancer. That is why both tomatoes and their derivatives are being considered as functional foods and there are already lycopene capsules on the market. However, like most active ingredients in foods, the levels of lycopene in tomatoes are too low to achieve the desired effect through ingestion.}]]> 2021-08-28 21:56:24 UTC https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702187337 Science in the NewsSame Science, Different Policies: Regulating Genetically Modified Foods in the U.S. and Europe. melanyvargasr2000 https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702188515 _{Approval of GM foods at the EU level may conflict with the regulatory policies of individual member state governments, and the ultimate decision-making power has recently shifted to the latter. Before this year, EU countries could ban the use and cultivation of approved GM foods within their borders if additional data not used during the original approval process demonstrated that the foods pose a risk to human or environmental health.}]]> 2021-08-28 22:00:20 UTC https://padlet.com/melanyvargasr2000/wgoqz99bq87r4h9/wish/1702188515
