Transgenic soybean is a soybean plant whose genome has been changed by genetic engineering technology.
these techniques usually include introducing genes from other species or genes that change soybean itself into soybean plants, so as to increase soybean resistance, yield, quality or other characteristics. These technologies aim to create more stress-tolerant, high-quality and high-yield soybean varieties by changing the plant genome.
traditionally, the methods of improving crop varieties include breeding, hybridization and mutation. However, these technologies need to spend a lot of time, manpower and material resources, and progress is slow. With the introduction of genetic engineering technology, scientists can modify the genes of plants more quickly and accurately, and create new and high-quality crop varieties.
genetically modified soybeans are widely planted all over the world, and the largest producers are the United States, Brazil and Argentina. According to the data of USDA, the planting area of genetically modified soybeans in the United States is about 95 million acres, accounting for more than 9% of the soybean planting area in the country. The planting area of genetically modified soybeans in Brazil and Argentina is also very large.
Principle of transgenic soybean:
The development of transgenic soybean is to cooperate with the use of glyphosate herbicide. Herbicide is selective and non-selective, while glyphosate is a non-selective herbicide. Glyphosate-resistant transgenic crops are the largest transgenic crops in the world at present. The principle of glyphosate killing plants is to destroy EPSPS in chloroplasts or woody bodies of plants.
through transgenic method, plants can produce more EPSPS enzymes to resist glyphosate, so that crops will not be killed by glyphosate herbicide. With this transgenic soybean, farmers don't need to use a variety of herbicides as in the past, but only glyphosate herbicide can kill all kinds of weeds.
