Total tocopherol, anthocyanin, chlorophyll, and carotenoid levels in stressed wild-type and 35S::HPT1 leaves. Plants of the indicated genotypes were grown in a 10-h/14-h light/dark cycle at 75 to 100 μmol photons m–2 s–1 for 6 weeks and then transferred to approximately 900 μmol photons m–2 s–1 growth conditions. A, Total tocopherol levels in leaves of stressed wild-type and 35S::HPT1 plants. High-light stress resulted in a significant elevation of total tocopherol levels in both 35S::HPT1 transgenic and wild-type plants. B, Anthocyanin accumulation in leaves of stressed wild-type and 35S::HPT1 Arabidopsis plants. Anthocyanin levels increased within the first 3 d of stress and reached high steady-state levels after 6 d of stress treatment. C, Chlorophyll and carotenoid degradation in leaves of stressed wild-type and 35S::HPT1 plants. Total chlorophyll and carotenoid levels decreased gradually to approximately 50% of the initial levels in all stressed lines.
