Abstract: In recent years, nano-materials have become a research hotspot in the field of agriculture, and have been gained much attention internationally. Nanomaterials, because of their small size, can be absorbed by cells through endocytosis after penetrating the cell walls, and then affect the growth of plants. Nanomaterials are widely used in the crop research fields such as plant genetic transformation, crop growth and health, especially in the field of genetic transformation, which can be used as a transformation vector and integrated with gene editing technology for genetic improvement of crops. Based on this, the absorption and transport mechanism of nanomaterials in plants and their application in crops were reviewed, with emphasis on the research progress of nanomaterials in plant genetic transformation. The remaining issues and the future development direction of nanomaterials in crops were prospected, in order to provide reference for broadening the application  of nanomaterials.

Key words: nanomaterials, endocytosis, transportation, genetic transformation, genome editing
