Alterations in tocopherol cyclase activity in transgenic and mutant plants of Arabidopsis affect tocopherol content, tocopherol composition, and oxidative stress.

Abstract excerpt

Tocopherol belongs to the Vitamin E class of lipid soluble antioxidants that are essential for human nutrition. In plants, tocopherol is synthesized in plastids where it protects membranes from oxidative degradation by reactive oxygen species. Tocopherol cyclase (VTE1) catalyzes the penultimate step of tocopherol synthesis, and an Arabidopsis (Arabidopsis thaliana) mutant deficient in VTE1 (vte1) is totally...
