Abstract
The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

222. A process for producing eicosapentaenoic acid and docosapentaenoic acid, comprising the steps of (i) growing a transgenic oilseed plant which comprises eicosapentaenoic acid and docosapentaenoic acid in an esterified form as part of triglycerides in its seed and a microalgal fatty acid desaturase, wherein the total fatty acid of the seed comprises at least 2.5% ω
- 3 C20 fatty acids (w/w) and wherein the docosapentaenoic acid is present at a level based on a conversion ratio of eicosapentaenoic acid to docosapentaenoic acid of at least 5% (w/w), and (ii) harvesting the seed from the transgenic plant.
