Advances in genetic engineering of plant virus resistance

Plant virus is one of the most economical devastating microorganisms for global agriculture. Although several strategies are useful for controlling viral infection, such as resistant breeds cultivation, chemical bactericides treatment, blocking the infection source, tissue detoxification and field sanitation, viral disease is still a problem in agricultural production. Genetic engineering approach offers various options for introducing virus resistance into crop plants. This paper reviews the current strategies of developing virus resistant transgenic plants.
