Abstract: Genome editing based on sequence-specific nucleases could introduce targeted genome modifications, such as site-directed gene disruption, gene replacement or insertion in various species. As a preciseand efficient tool for genome engineering, genome editing has been extensively studied and widely applied during pastseveral years, and it would eventually change the current status of biotechnology. Genome editing system has now been established in plants, especially crops and already displayed its great potential in the field of plant biotechnology.In this review, we first briefly explain the working principles of different genome editing systems, and then list some examples of different applications of genome editing in plant research and breeding. Finally, we discuss the opportunities and challenges brought by genome editing to plant biotechnology.

Key words: sequence-specific nuclease, genome editing, plant genome engineering
