Abstract
With the global challenges of climate change and biodiversity loss, the sustainable utilization of forest resources is facing severe tests. This study focuses on gene editing technology, exploring its application potential and future development directions in forest tree improvement. By employing advanced gene-editing tools such as CRISPR/Cas9, targeted experiments were conducted on specific tree species to enhance abiotic stress tolerance, growth rate, and wood quality. The results demonstrate that gene-editing technologies can accurately target and efficiently modify genes of interest, significantly improving trees' adaptability to environmental stresses such as drought and pest infestations. Moreover, this technology successfully optimized the fiber structure of wood, offering new avenues for the development of high-value-added forest products. Innovatively, this study proposes a multi-gene协同editing strategy, overcoming the low efficiency bottleneck of traditional breeding methods and opening up new pathways for forest tree genetic improvement. Overall, the application of gene-editing technologies in forestry exhibits immense potential, promising to advance forest production toward precision and intelligence while providing robust technical support for ecological conservation and the sustainable use of resources.
