Abstract:

Efficient genetic transformation technology is the prerequisite for the identification of functional genes for important traits in plants and the basis for transgenic breeding.With the development of nanotechnology,the genetic transformation technology of plant based on gene vector constructed by nano particle has shown great application potential. The type and properties of nano particle applied in gene vector of plant,its combination way with DNA and the basic principle of gene transfection technology were reviewed. In the meanwhile,the important factors that affect the performance and transformation efficiency of nano-gene vector,as well as the transformation methods by which nano-gene vectors mediate exogenous genes into plant cells,were expounded emphatically. The advantages of nano-gene vectors were analyzed compared with that of other vectors. Further researches are needed to improve the stable genetic transformation,gene editing and in planta transformation with nano-gene vector,which will provide new ideas for plant genetic transformation technology and methods.

Key words: nanoparticle, gene vector, vector performance, transformation method
