Genetic engineering has been widely used in planting, breeding, medical care and environmental protection. First of all, in agriculture, my country’s genetically modified plants have been developed rapidly with the help of the 863 Program, mainly focusing on the improvement of varieties such as insect resistance and stress resistance, etc., to market Genetically modified crops include herbicide-resistant soybeans, insect-resistant corn, virus-resistant rapeseed, virus-resistant potatoes, and the insect-resistant cotton we just mentioned. The largest planting area is genetically modified soybeans and cotton.
Mouse test
Research on genetically modified animals is also in full swing. Firstly, it has been successful in mice. The research focuses on the improvement of poultry and livestock breeds in order to obtain fast-growing and high-quality poultry and livestock. The genetically modified animals can also be used to produce drugs and ornaments. A successful transgenic animal: the mouse has been transformed into the rat growth hormone gene, and the result is more than twice as large as usual. The transgenic lean pig and the fast-growing fish of high-yielding dairy cows have also entered the practical stage. In addition to improvement, genetically modified animals can also be used to replace fermenters to produce precious proteins. The principle is to express foreign genes in mammary cells and extract the required proteins from the milk. For example, a sheep can be equivalent to a ton each year. The fermenter does not require water, electricity, equipment and so on.
