MARCHANTIALES-DERIVED UNSATURATED FATTY ACID SYNTHETASE GENE AND USE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To efficiently produce highly unsaturated fatty acids such as arachidonic acid and eicosapentaenoic acid in higher plants.

SOLUTION: From a single species of Marchantia polymorpha, a Δ5 fatty acid desaturase gene, a Δ6 fatty acid desaturase gene, and a Δ6 fatty-acid-chain elongase gene are isolated. By introducing these genes into higher plants to be expressed, transformed plants which can produce arachidonic acid and eicosapentaenoic acid are obtained.
