[Purpose] Climate change and the rapid depletion of fossil fuel reserves necessitate the development of sustainable and low-carbon energy alternatives. This study aims to enhance the suitability of Brassica juncea oil for biofuel applications by reducing its viscosity and improving its physicochemical properties through metabolic engineering.
[Method] An optimized Agrobacterium-mediated transformation system was employed to develop transgenic B. juncea lines expressing the Euonymus alatus diacylglycerol acetyltransferase (EaDacT) gene, responsible for synthesizing acetyl-triacylglycerols (acTAGs). Additionally, key lipid metabolism enzymes, including DGAT and PDAT, were modulated to redirect carbon flux toward acTAG production.
[Results] The transgenic lines successfully accumulated seed oils enriched in acetyl-TAGs, exhibiting significantly reduced viscosity and enhanced fluidity compared to conventional oils. These improved properties make the modified oils highly suitable for direct use as biodiesel and advanced biofuel feedstocks. [Consideration] The study highlights the effectiveness of metabolic engineering in tailoring oil composition; however, further evaluation under field conditions, regulatory considerations, and large-scale production feasibility are essential for commercial deployment.
[Conclusion] This research demonstrates that metabolic engineering of oilseed crops can produce customized plant oils with improved fuel properties, contributing to sustainable bioenergy systems, reduced greenhouse gas emissions, and climate-resilient energy solutions.
