Plant lipids, mainly stored in seeds and other plant parts, are not only a crucial resource for food and fodder but are also a promising alternative to fossil oils as a chemical industry feedstock. Oil crop cultivation and processing are always important parts of agriculture worldwide. Vegetable oils containing polyunsaturated fatty acids, very long chain fatty acids, conjugated fatty acids, hydroxy fatty acids and wax esters, have outstanding nutritional, lubricating, surfactant, and artificial-fibre-synthesis properties, amongst others. Enhancing the production of such specific lipid components is of economic interest. There has been a considerable amount of information reported about plant lipid biosynthesis, including identification of the pathway map of carbon flux, key enzymes (and the coding genes), and substrate affinities. Plant lipid biosynthesis engineering to produce special oil compounds has become feasible, although until now, only limited progress has been made in the laboratory. It is relatively easy to achieve the experimental objectives, for example, accumulating novel lipid compounds in given plant tissues facilitated by genetic modification. Applying such technologies to agricultural production is difficult, and the challenge is to make engineered crops economically attractive, which is impeded by only moderate success. To achieve this goal, more complicated and systematic strategies should be developed and discussed based on the relevant results currently available.

主要储存在种子和其他植物部位的植物脂质不仅是食品和饲料的重要资源，而且还是有前途的矿物油替代化学工业原料的植物。油料作物的种植和加工一直是全世界农业的重要组成部分。含有多不饱和脂肪酸，超长链脂肪酸，共轭脂肪酸，羟基脂肪酸和蜡酯的植物油具有出色的营养，润滑，表面活性剂和人工纤维合成性能。增强此类特定脂质成分的生产具有经济意义。关于植物脂质生物合成的报道已有大量信息，包括鉴定碳通量，关键酶（和编码基因）和底物亲和力的途径图。尽管迄今为止，在实验室中仅取得了有限的进展，但用于生产特殊油类化合物的植物脂质生物合成工程已变得可行。相对容易达到实验目的，例如，通过遗传修饰在给定的植物组织中积累新型脂质化合物。将这样的技术应用于农业生产是困难的，挑战是使工程农作物在经济上具有吸引力，这只能通过适度的成功而受到阻碍。为了实现这一目标，应根据当前可获得的相关结果，开发和讨论更复杂，系统的策略。相对容易达到实验目的，例如，通过遗传修饰在给定的植物组织中积累新型脂质化合物。将这样的技术应用于农业生产是困难的，挑战是使工程农作物在经济上具有吸引力，这只能通过适度的成功而受到阻碍。为了实现这一目标，应根据当前可获得的相关结果，开发和讨论更复杂，系统的策略。相对容易达到实验目的，例如，通过遗传修饰在给定的植物组织中积累新型脂质化合物。将这样的技术应用于农业生产是困难的，挑战是使工程农作物在经济上具有吸引力，这只能通过适度的成功而受到阻碍。为了实现这一目标，应根据当前可获得的相关结果，开发和讨论更复杂，系统的策略。
