Abstract excerpt
The m (Tph(1)) mutation partially disrupts the synthesis of alpha-tocopherol (vitamin E) in sunflower (Helianthus annuus L.) seeds and was predicted to disrupt a methyltransferase activity necessary for the synthesis of alpha- and gamma-tocopherol. We identified and isolated two 2-methyl-6-phytyl-1,4-benzoquinone/2-methyl-6-solanyl-1,4-benzoquinone methyltransferase (MPBQ/MSBQ-MT) paralogs from sunflower (MT-1...
