title: Enhanced tolerance to drought stress in transgenic tobacco plants overexpressing VTE1 for increased tocopherol production from Arabidopsis thaliana.
abstract: Tocopherol cyclase (VTE1, encoded by VTE1 gene) catalyzes the penultimate step of tocopherol synthesis. Transgenic tobacco plants overexpressing VTE1 from Arabidopsis were exposed to drought conditions during which transgenic lines had decreased lipid peroxidation, electrolyte leakage and H(2)O(2) content, but had increased chlorophyll compared with the wild type. Thus VTE1 can be used to increase vitamin E content of plants and also to enhance tolerance to environmental stresses.
