Abstract: Genome editing using targetable nucleases is an emerging technology for the precise genome modification. The CRISPR (clustered regularly interspaced short palindromic repeats) system, which appeared in 2013, has been modified to serve as RNA-guided endonuclease (known as CRISPR/Cas9). CRISPR/Cas9 has been developed into the third generation of genome editing technology, which is widely used in genome editing among varieties of species including plants with high efficiency and specificity. Furthermore, owing to its simplicity, convenience, and flexibility, CRISPR/Cas9 technology has dramatically accelerated genetic engineering and functional genomics, brought a revolutionary change in every research field of life science studies. This review briefly introduced the emergence and developing of CRISPR/Cas9, described the mechanism of CRISPR/Cas9 mediated genome editing, summarized the application of this tool in crop breeding that aimed at improving crop quality and yield. Finally, we discussed the prospect and application value of CRISPR/Cas9 in crop breeding, so as to provide a theory basis for its use in novel germplasm innovation and crop breeding improvement.
