Abstract

Plant diseases and insect pests are major threats to agricultural production and food security. Genome editing offers a precise, efficient way to breed resistant crops, addressing key limitations of traditional breeding methods. This paper reviews the latest advances in CRISPR-Cas9-mediated genome editing for disease and insect resistance in crops including strawberry, cucumber, tobacco, and cotton. It highlights representative cases of key target gene discovery worldwide, and discusses current technological developments, global regulatory frameworks, and future prospects of genome editing. Research confirms that this technology enables precise trait improvement without exogenous gene integration, providing critical support for food security and the green transformation of agriculture.
