1, transgenic papaya
It is reported that more than 95% of the papaya sold in the market is papaya, which may be unimaginable to many people.
Soybeans and bean products (including soybean oil)
2. Non-GM soybeans:
Oval, slightly flat. The navel is light brown. Beans come in different sizes. Soymilk is milky white.
3. Genetically modified soybeans
Turn around. The navel is yellow or brown. Beans are about the same size Soymilk is light yellow, and bean products made from this bean are a little yellow.
4. Some rice and rice
Hubei is an area where China has obtained the legal planting right of genetically modified rice, and the slender and bright rice may be genetically modified rice. It is easy to be confused with the "long grain fragrance" in the northeast.
5. Corn and corn oil
20 1 1 year, the proportion of transgenic cotton planting in China is as high as 7 1.5%, and there are too many varieties of domestic transgenic cotton approved, at least hundreds.
Genetically modified corn: sweet, crisp, full and graceful, with similar head and tail particles, commonly known as sweet corn (but not all sweet corn is genetically modified), and all imported corn is basically genetically modified corn.
Genetically modified corn oil: When you buy corn oil in the supermarket, you can check the label and tell whether it is genetically modified corn oil.
According to statistics, by the beginning of 1999, USDA had approved the production of 35 kinds of transgenic crops in 7 categories, including 5 kinds of late-maturing tomatoes and 2 kinds of herbicide-resistant soybeans.
Only these two kinds of papaya saved the papaya industry in Hawaii, USA. China has approved four commercial productions, including the transgenic tomato "8805R" with resistance to cucumber mosaic virus cultivated in Peking University.
Extended data:
A biotechnology developed rapidly in 1980s is to cultivate new varieties through transgenic means. Its main technology is to obtain DNA fragments with specific excellent genetic traits from target donor species.
Attention should be paid to the introduction of the target gene directly or through a vector into the embryo of the transformed species, that is, the "recipient species", so as to cultivate excellent new varieties.
