Abstract: Gene editing technology, as a disruptive technology, has been widely used in crop genetic improvement, showing great development potential and application value. While increasing technology research and development, countries are also very concerned about the potential safety problems, and have introduced safety regulatory policies for gene editing crops. This paper mainly introduced the latest research progress of CRISPR system in plants (the mechanism of various newly developed variants of CRISPR, the application and challenges of CRISPR system), detection methods of gene editing plants and international regulatory policies. The paper was expected to provide theoretical data for the formulation of regulatory policies for gene editing crops in China.

Key words: CRISPR-Cas system variant, CRISPR-Cas system application, CRISPR-Cas system regulatory policy
