The DNA is modified using genetic engineering methods. We can use technology to transfer genes between organisms now. Most of purpose is to introduce a new biology to the plant. Most of purpose is to introduce a new biology to the plant. This system gives advantages like improving shelf life, higher yield, infection resistance, etc. Also they made up of vaccines, so it is good for human diseases. Especially, children can be infected diseases, but transgenic plants can protected for diseases.

In 1983, the first transgenic plants were reported. Then, many recombinant proteins have been expressed species of plants including tobacco, corn, tomato, potato, banana, etc. Tobacco plants were usually used, however, banana and potato are considered for vaccines.

GMO corn                        

It needs 6% less pesticide and produces 7.6% higher yield. Also increased farmer pay $44.1 billion. Corn is including bacteria, so it is good for diseases. Actually, they are thinking for vaccines of human.

GMO tobacco

 We are usually used for medical research. For example, experiment drug called ZMAPP, which was developed virus disease.
