This study aims to evaluate the potential of genome editing technologies in improving wood quality traits of Eucalyptus, focusing on the current advancements of tools such as CRISPR/Cas9, base editing, and prime editing, and their application in Eucalyptus breeding programs. Significant progress has been identified in modifying lignin content and composition, enhancing cellulose content and fiber quality, and optimizing wood density and pulp yield using genome editing technologies. The results demonstrate the successful application of CRISPR/Cas9 targeting lignin biosynthesis genes, precise genetic modifications using base and prime editing, and the development of genomic selection models for predicting wood traits in Eucalyptus. Case studies highlight integrative approaches to simultaneously improve growth and wood quality traits, the use of regional heritability mapping to identify stable QTLs, and the implementation of genomic selection in breeding programs. The findings emphasize the transformative potential of genome editing in Eucalyptus, providing a pathway for efficient and sustainable improvement of wood quality traits. Integrating genome editing with traditional breeding methods and omics technologies can accelerate the development of superior Eucalyptus varieties. Future research should focus on advancing genome editing tools, conducting extensive field trials, and addressing ethical and regulatory issues to fully realize the potential benefits of these technologies.
