The so-called genetically modified plant breeding is the human application of biological genetic engineering self-proclaimed to cut and suture a biological gene to another organism. This genetic engineering can be carried out between animals, plants and bacteria. The genetic DNA is transferred to each other and recombined. According to human will to transform the genetic traits of plants, to cultivate new varieties of plants that cannot be found in nature.
How will bioengineering and plant genetic engineering develop in the 21st century?
The 21st century crop bio-engineering and transgenic plant engineering will make a major contribution to the sustainable development of the world's agriculture. Genome research will shift from structural genomes to functional genomes. The gene banks are constructed for major crops such as rice, wheat, corn, potatoes, and the like. The genes are then isolated and cloned using transposon tagging T-DNA tags or positional cloning techniques. In the 21st century, whoever first learned to understand the function of genes, whoever has the intellectual property rights of the gene.
In the 21st century, plant genetic engineering will evolve from single gene traits to multiple genes. That is to say, combining various genes such as insect resistance, disease resistance, and high yield, the plants will get better varieties.
At the same time, more research will be conducted on the use of genetic engineering to transfer healthy genes to plants and crops to change the quality of plants. Foods made from food crops become healthy foods, functional foods, and nutritious foods.
For example, ordinary rice does not contain the vitamin A needed by the human body. Through genetic engineering, it can make rice rich in vitamin A. People who eat this kind of rice cannot suffer from night blindness or various diseases caused by lack of vitamin A.
Tomatoes and potatoes are people's favorite vegetables. Through genetic engineering, people will cultivate new varieties of tomatoes on the ground and a long underground potato. Potatoes with a protein content equal to that of meat can also be cultivated. Add the watermelon gene and let the bell pepper grow like a watermelon.
Through genetic engineering, people will soon develop plants that are drought-resistant, alkali-resistant, resistant to land-poor ridges, and resistant to heavy metal pollution. Provide excellent tree species and grass species for the transformation of desertification and environmental pollution.
Transgenic plant breeding
People say that the 21st century will be the century of biotechnology. In recent years, bioengineering, crop genetic engineering and plant genetic engineering technology have made great achievements. A number of new crop varieties with insect resistance, disease resistance, herbicide tolerance and high yield and quality have been successfully cultivated. Modern biological sciences have discovered that the proliferation of various organisms is due to the presence of genetic material DNA in biological cells. This double helix of DNA, or biological genes, dominates the history of biological transmission.
