Tocopherol composition and levels in leaves of 5-week-old wild-type, 35S::γ-TMT, 35S::HPT1, and double 35S::γ-TMT/ 35S::HPT1 overexpressers. Leaf tissue (approximately 70 mg) was extracted, and individual tocopherols were separated and quantified by normal phase HPLC. Each line is represented as an average ± sd from three plants. Total tocopherol levels of 35S::HPT1 and 35S::γ-TMT/35S::HPT1 plants were significantly higher than wild-type levels (P < 0.005). The excess γ-tocopherol in double transgenics was methylated to α-tocopherol.
