    • The present invention relates to methods for large-scale production of conjugated fatty acids, especially conjugated linoleic acids in plants. More specifically, the present invention relates to genes identified from Calendula officinalis coding for a conjugase and its related enzyme, a Δ12 desaturase, and utilization of them for large scale production of conjugated linoleic and linolenic acids in plants. The genes encoding a conjugase can introduce two conjugated double bonds at 8 and 10 positions, and a Δ12 desaturase can introduce a double bond at 12 position of acyl chains. The constructs containing these genes can be transferred to plants with different substrate profiles, which allows for the production of conjugated linoleic acids (18:2, Δ8, Δ10) and linolenic acids (18:3, Δ8, Δ10, Δ12) in plant seeds on a commercial scale.
    • 本发明涉及用于在植物中大规模生产共轭脂肪酸,特别是共轭亚油酸的方法。 更具体地说,本发明涉及从编码结合酶及其相关酶的Calendula officinalis鉴定的基因,DELTA 12去饱和酶,以及它们用于大规模生产植物中共轭亚油酸和亚麻酸的基因 。 编码结合酶的基因可以在8位和10位引入两个共轭双键,并且DELTA 12去饱和酶可以在酰基链的12位引入双键。 含有这些基因的构建体可以转移到具有不同底物轮廓的植物中,这允许生成共轭亚油酸(18:2,DELTA 8,DELTA 10)和亚麻酸(18:3,DELTA 8,DELTA 10,DELTA 12)在商业规模的植物种子中。
