Precise genome editing process and its applications in plants driven by AI

Genome editing technologies have emerged as the keystone of biotechnological research, enabling precise gene modification. The field has evolved rapidly through revolutionary advancements, transitioning from early explorations to the breakthrough of the CRISPR-Cas system. The emergence of the CRISPR-Cas system represents a huge leap in genome editing, prompting the development of advanced tools such as base and prime editors, thereby enhancing precise genomic engineering capabilities. The rapid integration of AI across disciplines is now driving another transformative phase in genome editing, streamlining workflows and enhancing precision. The application prospects of genome editing technology are extensive, particularly in plant breeding, where it has already presented unparalleled opportunities for improving plant traits. Here, we review early genome editing technologies, including meganucleases, ZFNs, TALENs, and CRISPR-Cas systems. We also provide a detailed introduction to next-generation editing tools—such as base editors and prime editors—and their latest applications in plants. At the same time, we summarize and prospect the cutting-edge developments and future trends of genome editing technologies in combination with the rapidly rising AI technology, including optimizing editing systems, predicting the efficiency of editing sites and designing editing strategies. We are convinced that as these technologies progress and their utilization expands, they will provide pioneering solutions to global challenges, ushering in an era of health, prosperity, and sustainability.
