Research Progress on Metabol ic Engineering of Vitamin E in Plants
Plant metabolic engineering is a new orientation in plant research area and vitamin E with the biological activity for life organism is an essential vitamin for animals. Isolation and functional verification of total genes participated in vitamin E metabolic pathway is finished successfully.Adjusting the relevant genes and enzymes in vitamin E synthetic pathway by using plant metabolic engineering is the important significance in enhancing vitamin E content and activity.Research progress on plant vitamin E metabolic engineering is reviewed from five aspects of vitamin E research history,vitamin E metabolic pathway,the relevant enzymes and genes in vitamin E metabolic pathway,vitamin E metabolic engineering in model plants and its utilization in important crops.The vitamin E metabolic flux controlled by the metabolic engineering in future is prospected either.
