Mène-Saffrané, Laurent Pellaud, Sébastien 2017-03-16 Vitamin E refers to four tocopherols and four tocotrienols that are exclusively synthesized by photosynthetic organisms. While α-tocopherol is the most potent vitamin E compound, it is not the main form consumed since the composition of most major crops is dominated by γ-tocopherol. Nutritional studies show that populations of developed countries do not consume enough vitamin E and that a large proportion of individuals exhibit plasma α-tocopherol deficiency. Following the identification of vitamin E biosynthetic genes, several strategies including metabolic engineering, classic breeding and mutation breeding, have been undertaken to improve the vitamin E content of crops. In addition to providing crops in which vitamin E content is enhanced, these studies are revealing the bottlenecks limiting its biosynthesis. application/pdf https://folia.unifr.ch/global/documents/305556 https://folia.unifr.ch/documents/305556/files/men_csv.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.copbio.2017.01.007 info:eu-repo/semantics/openAccess License undefined Current Opinion in Biotechnology. - 2017, vol. 44, p. 189–197 info:eu-repo/classification/udc/57 Current strategies for vitamin E biofortification of crops http://purl.org/coar/resource_type/c_6501
