Abstract:
1. A process for the production of arachidonic acid or eicosapentaenoic acid or arachidonic acid and eicosapentaenoic acid in transgenic plants that produce mature seeds with a content of at least 1% by weight of said compounds referred to the total lipid content of said organism which comprises: a) introducing at least one nucleic acid sequence in said transgenic plant, which encodes a polypeptide having a Δ-12-desaturase and Δ-15-desaturase-activity, and b) introducing at least one second nucleic acid sequence in said transgenic plant, which encodes a polypeptide having a Δ-9-elongase-activity, and c) introducing at least one third nucleic acid sequence in said transgenic plant, which encodes a polypeptide having a Δ-8-desaturase-activity, and d) introducing at least one fourth nucleic acid sequence, which encodes a polypeptide having a Δ-5-desaturase-activity, and e) cultivating and harvesting of said transgenic plant, wherein the nucleic acid sequence which encodes a polypeptide having Δ-12-desaturase and Δ-15-desaturase activity comprises a nucleic acid sequence selected from the group consisting of
