Abstract: With the development of nanotechnology, nano materials have been increasingly used for delivering genetic materials into plant cells for engineering purposes, which represent a major breakthrough in the 21^st century. In this article, we reviewed the advancement of genetic engineering in plant using nanomaterials, including hydroxyapatite, silica, carbon nanotube, magnetite and quantum dots. The advantages and disadvantages of those materials were summarized. The effects of nanomaterials on the physiology of plant cells, as well as the mechanisms by which those nanomaterials are transported across cells are still largely unclear. The cellular biological and biochemistry mechanisms related to this process also need to be clarified. As a result, developing much safer nanomaterials that can specifically deliver genetic materials into target cells or even sub cellular compartments, with highly efficient payload release and functioning will be a main focus in future nanomaterial research.
