| Abstract: | In recent years, many genes in biosynthesis of long-chain polyunsaturated fatty acids （LCPUFAs） have been cloned and identified, and their biosynthetic mechanism has been elucidated. However, most higher plants dont produce LCPUFAs which have been playing important roles in human health. This review covered the latest advances on LCPUFAs biosynthesis in higher plants by genetic engineering, and discussed the current problems in genetic improvement and some feasible solutions to solve these problems. |
