Abstract: Transgenic technology plays an important role in the cultivation of excellent new varieties of animals and plants. With the development of nanobiotechnology, genetic transformation technology of animals and plants, which is based on gene vector constructed by nano-materials, is of great significance in developing novel transgenic methods for animals and plants, accelerating the largescale preparation of genetically modified germplasm materials and the process of cultivating new varieties. The types and properties of nano-gene vectors were reviewed. And in combination with the progress on genetics and breeding of animals and plants, the characteristics and advantages of nano-gene vectors compared with other vectors were analyzed. In the meantime, the basic principle and operation process of gene transfection technology based on nano-gene carrier, as well as its application in genetic transformation of animals and plants were expounded emphatically, which was expected to provide a new thought for genetic engineering transformation of animals and plants.

Key words: transgenosis, genetic engineering of animals and plants, gene transfection technology, nano-gene vector
