The ability to genetically engineer plants has facilitated the generation of oilseeds synthesizing non-native fatty acids. Two particular classes of fatty acids are considered in this review. First, so-called industrial fatty acids, which usually contain functional groups such as hydroxyl, epoxy, or acetylenic bonds, and second, very long chain polyunsaturated fatty acids normally found in fish oils and marine microorganisms. For industrial fatty acids, there has been limited progress toward obtaining high-level accumulation of these products in transgenic plants. For very long chain polyunsaturated fatty acids, although they have a much more complex biosynthesis, accumulation of some target fatty acids has been remarkably successful. In this review, we consider the probable factors responsible for these different outcomes, as well as the potential for further optimization of the transgenic production of unusual fatty acids in transgenic plants.

转基因植物中异常脂肪酸的产生

基因工程植物的能力促进了合成非天然脂肪酸的油籽的产生。本综述考虑了两类特定的脂肪酸。一是所谓的工业脂肪酸，通常含有羟基、环氧或炔键等官能团；二是通常存在于鱼油和海洋微生物中的超长链多不饱和脂肪酸。对于工业脂肪酸，在转基因植物中获得这些产品的高水平积累方面进展有限。对于非常长链的多不饱和脂肪酸，虽然它们的生物合成要复杂得多，但一些目标脂肪酸的积累已经非常成功。在本次审查中，我们考虑了导致这些不同结果的可能因素，
