Research advances in genetic engineering of plantibody

The combination of engineering antibody and plant biotechnology creates the plantibody. It has been reported that the engineering antibodies expressed in plant, no matter whether they are intact or small-molecular antibodies, keep their antigen-binding specificity, which means they are functional. This trait makes plantibody notable. Now the researches are focused mainly on the following three aspects: (i) Therapeutic antibody in clinic. It is expected to offer the opportunity of large-scale antibody procluction in agriculture systems, for the purpose of decreasing the cost greatly. Moreover, the property of multiple sexual hybridization between plants can be used to produce bior multi-functional antibodies and create new antibody medicines. (ii) Plant physiology. Engineering antibodies against plant hormones or some active materials can block their activities in plant, so the trait of plantibody could be used to study the growth and development of plant. (iii) Plant disease-resistance. The gene of antibody against plant virus can be transferred into plant to defend the intrusion of virus in order to cure the disease.
