摘要：

Cotton (Gossypium hirsutum L.), a vital global cash crop, significantly impacts both the agricultural and industrial sectors, providing essential fiber for textiles and valuable byproducts such as cottonseed oil and animal feed. The cultivation of cotton supports millions of livelihoods worldwide, particularly in developing regions, making it a cornerstone of rural economies. Despite its importance, cotton production faces numerous challenges, including biotic stresses from pests and diseases, and abiotic stresses like drought, salinity, and extreme temperatures. These challenges necessitate innovative solutions to ensure sustainable production. Genome editing technologies, particularly CRISPR/Cas9, have revolutionized cotton breeding by enabling precise genetic modifications. These advancements hold promise for developing cotton varieties with enhanced resistance to pests, diseases, and environmental stresses. Early genome editing tools like ZFNs and TALENs paved the way for more precise modifications but were limited by complexity and cost. The introduction of CRISPR/Cas-based technology with its simplicity and efficiency, has dramatically transformed the field, making it the preferred tool for genome editing in crops. Improved version of the technology like CRISPR/Cas12a, CRISPR/Cas13, base and prime editing, developed from CRISPR/Cas systems, provide additional tools with distinct mechanisms, further expanding their potential applications in crop improvement. This comprehensive review explores the impact of genome editing on cotton breeding and production. It discusses the technical challenges, including off-target effects and delivery methods for genome editing components, and highlights ongoing research efforts to overcome these hurdles. The review underscores the potential of genome editing technologies to revolutionize cotton cultivation, enhancing yield, quality, and resilience, ultimately contributing to a sustainable future for the cotton industry.
