Progress in Vitamin E Synthesis-related Enzyme Genes and in vivo Functions in Plants
植物VE合成相关酶基因克隆及VE在体内功能研究进展

There are 8 natural products of vitamin E designated as a, b, g, d-tocopherol and a, b, g, d-tocotrienol. Vitamin E plays an important role in plants, animals and humans physiologically. Vitamin E has close relations not only with reproduction but also with the central nervous system, digestive system, cardiovascular system and muscles. Also, it can be used as drug therapy for coronary disease, anaemia, and carcinoma. Green plants are basic sources of vitamin E for humans and animals.With the development of plant genomics and tropical genomics by rapid isolation of plant tropic metabolism-related enzyme genes and resolving the metabolism pathways, we are gradually approaching a strategy aimed at a better trophic value plus plant resources using metabolic engineering. In this context, this article discusses the current progress in vitamin E synthesis-related enzyme gene cloning and in vivo function exploration in plants.
