• Publication
  • Metabolic redesign of vitamin E biosynthesis in plants for tocotrienol production and increased antioxidant content, 2003, Nat Biotechnol.
  • SGD1, a key enzyme in tocopherol biosynthesis, is essential for plant development and cold tolerance in rice., 2017, Plant Sci.
• Genbank accession number
  • AX046728
• Key message
  • cDNAs encoding homogentisic acid geranylgeranyl transferase (HGGT), which catalyzes the committed step of tocotrienol biosynthesis, were isolated from barley, wheat and rice seeds
  • Overexpression of the barley HGGT in corn seeds resulted in an increase in tocotrienol and tocopherol content of as much as six-fold
  • Our results indicate that SGD1 is essential for plant development and cold tolerance in rice
  • A map-based cloning strategy and subsequent complementation test showed that SGD1 encodes homogentisate phytyltransferase (HPT), a key enzyme in tocopherol biosynthesis
