Abstract: The prime editing system based on CRISPR/Cas9 is a novel gene editing technology, which enables all 12 base-to-base conversions or transition, precise small insertion and deletion without requiring double-strand breaks or exogenous donor DNA templates. This review summarizes the development of gene editing approaches, the principle and characteristics of prime editing technique, as well as applications in animal and plant breeding and human gene therapy. It provides a reference for scientists to get insight into prime editing system and further use it in basic research and animal or plant breeding.

Key words: CRISPR/Cas9, prime editing(PE), pegRNA, application research
