- Abstract
Jojoba (Simmorulsia chinensis) is a unique oil plant that has attracted worldwide attention due to its high content o£ liquid wax esters in its seeds・ The oil content of jojoba seeds accounts for approximately 60% of the dry weight of the seeds, wjith 丘quid wax esters accounting for over 95% of the total oil content. Liquid wax esters have excellent properties such as oxidation resistance, high temperature resistance, and high insulation, making them widely applicable in fields such as cosmetics, pharmaceutical industry, and lubricants・ In the early stage, our research showed that fatty acyl CoA reductase (FAR) and wax synthase (WS) in jojoba seeds are key enzymes for liquid wax ester synthesis, while the high expression of WS and extremely low expression of diacylglycerol acyltransferase (DGAT) in jojoba seeds cotyledon are the main reasons why jojoba seeds can accumulate a large amount of liq・ uid wax esters・ The WS in jojoba seeds mainly synthesizes liquid wax esters of C42-C44 using C20:1-C22:1 fatty alcohols and fatty acids as substrates・ High erucic acid rapeseed contains abundant C22:l, making it an excellent receptor material for heterologous biosynthesis of jojoba oil. This article systematically describes the research progress and application prospects of jojoba oil. Combining the biosynthetic pathway of jojoba oil and the substrate preference of WS, it proposes the idea of using biotechnology to synthesize jojoba oil in high erucic acid rapeseed, providing reference for the industrial development of jojoba oil.
