Abstract: With the development and improvement of CRISPR/Cas9 system in genomic editing technology, the system has been applied to the prevention and control of animal viral infectious diseases, which has made considerable achievements. It has also been applied to the study of highly efficient gene targeting editing in plant virus genomes. The CRISPR/Cas9-mediated targeted gene modification has not only achieved the genome editing of plant DNA virus, but also showed the genome editing potential of plant RNA virus. In addition, the CRISPR/Cas9 system functions at the gene transcriptional and post-transcriptional level, indicating that the system could regulate the replication of plant viruses through different ways. Compared with other plant viral disease control strategies, this system is more accurate in genome editing, more stable in gene expression regulation, and has broader spectrum of resistance to virus disease. In this review, we summarized the advantages, main problems and development tendency of CRISPR/cas9 system in breeding of new antiviral plant germplasms.

Key words: CRISPR/Cas9 System, virus disease prevention and control, genome targeting modification
