Abstract excerpt
Wildtype sunflower (Helianthus annuus L.) seeds are a rich source of alpha-tocopherol (vitamin E). The g = Tph(2) mutation disrupts the synthesis of alpha-tocopherol, enhances the synthesis of gamma-tocopherol, and was predicted to knock out a gamma-tocopherol methyltransferase (gamma-TMT) necessary for the synthesis of alpha-tocopherol in sunflower seeds--wildtype (g(+) g(+)) lines accumulated > 90%...
