Abstract:

As an emerging genome editing system, the CRISPR/Cas system has been widely used in plant functional genome research and variety improvement due to its simplicity, efficiency, and high specificity. In this article, we systematically summarized the development and application of genome editing tools in plants. We focused on the latest advances in plant germplasm and variety improvement based on genome editing technology, and described a new strategy for plant breeding based on genome editing technology, which is difficult to achieve in traditional breeding. Finally, we also discussed the challenges that genome editing technology will face in future crop and food production.
