1, Bt crops can resist pests and reduce the use of pesticides; This crop can produce a kind of protein which is toxic to some pests. This kind of protein exists in Bacillus thuringiensis, a common soil bacterium.
2. Herbicide-resistant crops.
3. antiviral crops;
4. Nutritionally fortified crops; Its specific nutrients and vitamins are high.
Transgenic crops use genetic engineering to add the genes of the original crops to the genetic material of other organisms and remove the bad genes, thus producing better quality crops. Generally speaking, transgenic crops can increase crop yield, improve quality, and improve drought resistance and cold resistance.
Extended data:
Harmfulness of genetically modified crops;
1. Ecological hazards of genetic crops: natural crops are not afraid of pests, otherwise there will be no such crops in nature. After the first hybridization of crops, it is similar to gene transfer, but the proportion of gene change is very low, so people will begin to be afraid of pests. No matter how many times crops cross, the proportion of gene changes is always very low, and the highest is no more than 3%, which is the fundamental function of nature to maintain life. In this way, the harm to the human body is also very small.
2. The products made of genetically modified organisms are also very dangerous: injecting transgenic bovine growth hormone into cows to increase milk production, causing unnecessary diseases in cows, and increasing the concentration of IGF- 1 (growth promoting factor-1) in milk. IGF- 1 is known to be related to human breast cancer and prostate cancer.
3. In transgenic plants, the DNA after gene transformation is unstable: the transgenic genes often remain inactivated, some or all of the transgenic DNA will be lost, and even the transgenic DNA retained in the breeding period will be lost.
