Plant transgenic technology refers to the transfer of target genes separated from animals, plants or microorganisms into the genome of plants through various methods, so that they can be stably inherited and endowed with new agronomic traits, such as insect resistance, disease resistance, stress resistance, high yield and high quality. With the rapid development of modern biotechnology, plant transgenic technology is in the ascendant.

Since 1983 first obtained transgenic plants, more than 20 plants belonging to 35 families have been successfully transgenic. From 65438 to 0986, the first batch of transgenic plants were approved for field experiments. Up to now, 30 countries have approved thousands of transgenic plants for field experiments, involving more than 40 plant species.

Advantages of transgenic plants

Taking plants as experimental materials for biotechnology has its specific advantages, that is, most plant cells are totipotent and can differentiate into whole plants from a single cell. In this way, a single plant cell after genetic engineering may produce a complete transgenic plant.

Potential harm of transgenic plants

1, high yield and strong stress resistance will inevitably lead to the simplification and desalination of varieties.

2. The target gene of transgenic plants escapes, that is, cross-pollination with wild related species may produce new weeds.

3. Transgenic plants have strong stress resistance and can adapt to various harsh environments. Some crops share many characteristics with their overgrown ancestors. Therefore, some genetic changes may make crops themselves weeds. For example, genetically modified rice varieties with high salt tolerance may invade the harbor and breed into weeds.
