| 摘要 |
The invention relates to a method for producing polyunsaturated fatty acids in transgenic plants, whereby nucleic acids coding for polypeptides with &Dgr;-6-desaturase, &Dgr;-6-elongase, &Dgr;-5-desaturase, &Dgr;-5-elongase, &Dgr;-4-desaturase, &Dgr;-12-desaturase and/or ω-3-desaturase activity are introduced into the plants. Advantageously, said desaturases and elongases come from phytophtora sojae. The invention also relates to nucleic acid sequences, nucleic acid constructs, vectors and organisms containing the inventive nucleic acid sequences, vectors containing the nucleic acid sequences and/or the nucleic acid constructs, and transgenic plants containing the cited nucleic acid sequences, nucleic acid constructs and/or vectors. The invention further relates to fatty acid compositions produced according to the inventive method, and to the use thereof. |
