AB  - Tocopherols and tocotrienols have been originally identified as essential 
      nutrients in mammals based on their vitamin E activity. These lipid-soluble 
      compounds are potent antioxidants that protect polyunsaturated fatty acids from 
      lipid peroxidation. The biosynthesis of tocopherols and tocotrienols occurs 
      exclusively in photosynthetic organisms. The biosynthetic precursors and the 
      different pathway intermediates have been identified by biochemical studies and 
      the different vitamin E biosynthetic genes (VTE genes) have been isolated in 
      several plants and cyanobacteria. The characterization of transgenic plants 
      overexpressing one or multiple VTE genes combined with the study of vitamin E 
      deficient mutants allows from now on understanding the regulation and the 
      function of tocopherols and tocotrienols in plants.
