Advantages

In the technology of Plant Genetic Engineering, there are a lot of advantages or benefits that human or technology itself can get especially on agriculture. Genetic engineering has produced a revolution in molecular biology. Plant Genetic Engineering also had produced of valuable proteins and vaccine production in agriculture.

Some useful benefits of genetically modified plants in agricultural biotechnology are :

• Improved nutritional quality
• Better Nitrogen Fixation
• Reduced post harvest losses
• Disease resistant plant
• Enhanced efficiency of minerals used by plants to prevent early exhaustion for fertility of soil

Other than these benefits, Plant Genetic Engineering also have other benefits such as :

Production of Valuable Proteins

Production of valuable proteins is the recombinant DNA made possible the use of bacteria to produce proteins of medical importance. One example that genetically engineered is human insulin. Some important genetically engineered proteins include :

1. Human insulin 
2. Interferon - Antiviral agent which is secreted by cells which are attacked by virus. 
3. Growth hormone - Help in treatment of hypopituitary dwarfs. It also may prove useful in the treatment of bone fractures, skin burns and bleeding ulcers of digestive tract.

Vaccine production

Offer an advantage that the microbial strains from which the proteins are extracted do not contain complete viruses. Cloning directly into vaccinia virus DNA holds great promise, although vaccines so produced are not yet in the market. 

Vaccines can be produced using recombinant DNA technology or using cell culture. Crop plants can bear cheaper bioreactors to produce antigens to be utilized as Edible vaccines. These edible vaccines are said to be cheap alternative as compared to recombinant vaccines.

Production of Disease Resistant Plants

Genetic engineering can boost plant breeding efforts for developing disease resistant varieties. Now the disease resistant genes can be isolated and transferred to high yielding susceptible plants to produce pathogen free plants.
