Abstract (en)
[origin: WO03093482A2] The invention relates to a method for producing fatty acid esters which contain unsaturated fatty acids with at least three double-bonds, and free unsaturated fatty acids having a content of at least 1 wt.- %, in relation to the total amount of fatty acids contained in plants, by expression of at least one nucleic acid sequence which codes for a polypeptide having D-6-desaturase activity, and at least one nucleic acid sequence which codes for a polypeptide having D-6-elongase activity. Advantageously, said nucleic acid sequences can be expressed, optionally, together with a third nucleic acid sequence in the transgenic plant, which codes for a polypeptide having D-5-desaturase activity. The invention also relates to the use of defined nucleic acid sequences which code for polypeptides having a D-6-desaturase activity, D-6-elongase activity or D-5-desaturase activity, selected from a group of nucleic acid sequences, or to the use of nucleic acid structures containing the above-mentioned nucleic acid sequences.
