Method For The Production Of Gamma-Linolenic Acid And/Or Stearidonic Acid In Transgenic Brassicaceae And Linaceae

摘要

The present invention relates to the production of gamma-linolenic acid (18:3^Delta6,9,12) or stearidonic acid (18:4^{Delta6,9,12,15}) or gamma-linolenic acid (18:3^Delta6,9,12) and stearidonic acid (18:4^{Delta6,9,12,15}) in transgenic plants of the family Brassicaceae, where the transgenic plants comprise at least 10% by weight of oleic acid based on the total fatty acid content and, as the result of the activity of the Delta6-desaturases used in the method, have an increased Delta6-C₁₈-fatty acid content. The invention furthermore relates to novel nucleic acid sequences which code for the Delta6-desaturases used in the method, gene constructs comprising these nucleic acid sequences, a vector and transgenic plants comprising at least one nucleic acid sequence or a gene construct.
