Abstract:

Long-chain polyunsaturated fatty acids(LCPUFAs)play an important role in maintaining human health. The demand of edible EPA and DHA has significantly increased in recent years. However,the fish oil resource is obviously reduced due to the environmental pollution and the decline of the fishery resources,thus can’t meet the demands of people. The researchers have successively separated multiple genes that involved in LCPUFA synthesis and clarified the multiple LCPUFA synthetic pathways. LCPUFAs,especially DHA and EPA,have been successfully produced in monocot and dicot plants through genetic engineering. We summarized the latest research progress of LCPUFAs bio-synthesis and genetic engineering in higher plants,and analyzed the issues of LCPUFA synthesis,then proposed the possible solutions,and had an prospect of LCPUFA by genetic engineering.

Key words: long-chain polyunsaturated fatty acids, EPA, DHA, transgenic plant
