Plant Gene and Trait 2024, Vol.15, No.5, 243-252 http://genbreedpublisher.com/index.php/pgt 250 crucial support for future genetic improvements. Through these studies, transgenic E. ulmoides has shown great potential in increasing rubber yield, enhancing stress resistance, and optimizing the production of secondary metabolites. These developments have profound implications for the future of the Eucommia ulmoides industry. With further optimization of transgenic technologies, E. ulmoides is expected to significantly strengthen its position as a sustainable alternative to natural rubber. Furthermore, the medicinal value and production of other secondary metabolites in E. ulmoides will also be enhanced through these genetic engineering technologies, expanding its applications in the pharmaceutical and related industries. These advancements not only have the potential to improve the economic benefits of E. ulmoides but also reduce reliance on traditional rubber sources, promoting more environmentally friendly and sustainable industrial practices. Looking forward, the development potential of transgenic E. ulmoides is vast. However, as these technologies mature, ethical and ecological considerations must also be addressed. The long-term environmental impact of transgenic plants needs to be continuously monitored to ensure they do not negatively affect natural ecosystems. Additionally, as the E. ulmoides industry expands, it is necessary to establish clear regulatory frameworks to balance technological progress with social responsibility. Overall, transgenic E. ulmoides opens new horizons for rubber production and other industrial applications, but these advancements must be aligned with global sustainability goals to ensure their long-term environmental and economic benefits.
