用于在转基因生物中产生具有至少四个双键的多不饱和C20-和C22-脂肪酸的方法
摘要：
本发明涉及用于通过将核酸导入植物而在转基因植物中产生多不饱和脂肪酸的方法，其中所述的核酸编码具有Δ6‑去饱和酶、Δ6‑延长酶、Δ5‑去饱和酶、Δ5‑延长酶、Δ4‑去饱和酶、Δ12‑去饱和酶和/或ω3‑去饱和酶活性的多肽。这些去饱和酶和延长酶有利地衍生自大豆疫霉(Phytophthora sojae)。本发明还涉及核酸序列、核酸构建体、包含本发明核酸序列的载体和生物、包含核酸序列和/或核酸构建体的载体，并且涉及包含上述核酸序列、核酸构建体和/或载体的转基因植物。本发明的又一部分涉及由本发明方法产生的脂肪酸组合物及它们的用途。
摘要（英）：

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 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 fattyacid compositions produced according to the inventive method, and to the use thereof.
