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