What is the background and usefulness of genetically modified animals and plants?

Genetically modified animals and plants have always been a topic of social concern, and people are eager to bring great benefits to human beings, but on the other hand, they are afraid of what it brings. Human beings breed genetically modified organisms in order to increase the yield of certain production substances, such as genetically modified potatoes, wheat, genetically modified cattle and sheep, etc., and also to breed certain fungi to produce drugs that cannot be synthesized artificially... This will remain the focus of attention in the future.

1. Genetically modified soybeans.

Genetically modified soybeans are resistant to the herbicide glyphosate (poison drop mixture). Glyphosate kills common soybean plants along with weeds. This soybean is known as genetically modified soybean.

And this genetically modified technology has finally moved out of the laboratory and experimental fields into the daily cultivation of crops like corn, soybeans and cotton.

2. Cassava. Cassava is the third most numeric plant in the world after rice and maize, and is one of the staple foods in African countries. Currently, cassava production is stagnant due to fungal, bacterial and viral diseases. The Shanghai Institute for Biological Sciences, Chinese Academy of Sciences used small molecule RNA interference technology to inhibit the expression of related starch synthesis genes, and obtained a series of new cassava varieties with changes in the ratio of amylose and amylopectin content.

3. Papaya. Caricapapaya is a kind of herbaceous fruit tree with high edible and medicinal value, and papain is widely used in medicine, beauty, daily chemicals and other industries. Papaya ringspot mosaic virus (PRSV) is a worldwide virus that harms papaya production, and the plant cannot be effectively infected**, and current chemical fungicides cannot effectively control its spread.

Breeding disease-resistant varieties is one of the most urgent tasks for the prevention and control of ring-spotted mosaic virus, but there is a lack of effective disease resistance gene resources in papaya cultivars. It was not until 1986 that Abel et al. reported that the virus gene was transferred to the host plant, resulting in the phenomenon of plant resistance, inspired by this, breeders began to use transgenic technology to solve the problem of papaya's resistance to ringspot mosaic virus, and transgenic papaya resistant to ringspot virus came into being.

4. Cotton. Monsanto of the United States inserted the gene of Bacillus thuringiensis into cotton plants to obtain transgenic cotton plants, and after two consecutive years of field trials with the Agricultural Research Bureau and some university scientists, the effect of pest control is good.

5. Genetically modified potatoes.

Genetically modified potatoes are genetic techniques that scientists use to change the genes of potatoes as needed to obtain different types of potatoes. Some produce potatoes that need to change potato genes to obtain a single ingredient, some potatoes that are directly eaten by people after adding antiviral vaccines, and some that change potato genes to obtain different flavors of potatoes.

Hello, dear, sorry for the long wait, genetically modified plants are genetically engineered by introducing one or more exogenous DNA sequences into plant cells, so that plants can obtain new traits or characteristics. Here are some of the advantages of genetically modified plants:1

Increase yields: Genetically modified plants can increase yields by increasing disease resistance, drought tolerance, salt tolerance, etc. 2.

Reduced pesticide use: Genetically modified plants can be designed to be insect-resistant, antibacterial, or disease-resistant, thereby reducing the amount of pesticide used and reducing harm to the environment and humans. 4.

Increased resistance: Transgenic plants can be designed to be resistant to weed, drought, salt, etc., thereby increasing the plant's resistance and survivability. 5.

Promote environmental protection: Genetically modified plants can be designed to have the ability to absorb pollutants, thereby helping to purify the environment. It should be noted that genetically modified plants also have some controversies and risks, such as possible impacts on the natural environment and ecosystems, and may cause new human health problems.

Therefore, adequate safety assessment and regulation are required when using and promoting genetically modified plants. I hope mine can help you, if you don't understand anything, you can ask me again.

Genetically modified plants refer to the genetic modification of plants through genetic engineering technology to make them have certain new traits or functions. Here are some of the advantages of genetically modified plants:1

Improve the yield and quality of crops: Through transgenic technology, the crop can change the disease resistance, insect resistance, drought tolerance, salt tolerance and other traits of plants, so as to improve the yield and quality of crops. 2.

Reduce the use of pesticides: Genetically modified plants are insect resistant or disease resistant, which can reduce the amount of pesticides used, thereby reducing environmental pollution and health hazards to farmers. 3.

Improve food safety: Through transgenic technology, the disease resistance, insect resistance and other traits of crops can be improved, thereby reducing the use of pesticides and reducing the impact of pesticide residues on food safety. 4.

Conservation of resources: Genetically modified technology can improve the yield and quality of crops, thereby saving agricultural production resources such as land, water and fertilizers. 5.

Improve economic efficiency: Genetically modified technology can improve the yield and quality of crops, thereby increasing farmers' incomes and driving regional economic development. It should be noted that transgenic plants also have some potential risks and uncertainties, such as the impact on the environment and ecosystems, genetic drift and other issues, which need to be strictly evaluated and supervised.

Dear users, I think genetically modified plants have the following advantages:1Increased yields:

Genetically modified plants can increase the yield of crops by altering their genomes, such as increasing insect resistance, disease resistance, drought tolerance, etc. 2.Improving nutritional value:

Genetic plants can be genetically engineered to improve their nutritional value, such as increasing vitamin content and improving protein quality. 3.Reducing the use of chemical pesticides

Genetically modified plants can reduce the use of chemical pesticides by increasing their insect resistance, disease resistance, and other characteristics, thereby reducing pollution to the environment and impacts on human health. 4.Adapting to changes in the environment:

Genetically modified plants can be genetically engineered to increase their drought tolerance, cold tolerance and other characteristics, so as to adapt to climate change and adverse environmental conditions. 5.Improving economic efficiency:

Genetically modified plants can improve the yield and quality of crops, thereby increasing farmers' incomes and promoting the development of agriculture. Off-topic: Despite the many advantages of genetically modified plants, there are also some controversies.

Some people are concerned that genetically modified plants may pose potential risks to human health and the environment, such as potentially leading to new allergic reactions or diseases. In addition, the commercialization and patenting of genetically modified plants has sparked some controversy, with some arguing that it could lead to a reduction in farmers' dependence on rent-making and cultivation diversity. Therefore, there is a need to weigh the pros and cons, conduct scientific evaluation and regulation to ensure the safety and sustainability of genetically modified plants.

2.The survival rate of the organism or the effect that people want.

Cons: 1There are certain unknown dangers, such as the new virus2Biological diversity is threatened.

Existence is reasonable, even if it is ugly, it is normal.
