Impact of heat stress during seed development on soybean seed metabolome (2016, background): “The vte2-1 Arabidopsis mutant, which is nearly devoid of tocopherols, exhibits loss of seed viability and showed severe growth defects due to lipid peroxidation (Sattler et al. 2004).”
Specific Roles of α- and γ-Tocopherol in Abiotic Stress Responses of Transgenic Tobacco1[W][OA] (2007, background): “…protecting lipids and the photosynthetic apparatus against oxidative dam- age together with the antioxidants ascorbate, glutathione, and the photosystem-associated xanthophyll cycle (Porfirova et al., 2002; Sattler et al., 2004; Foyer and Noctor, 2005; Havaux et al., 2005; Kanwischer et al., 2005).”
The reduction of seed-specific dehydrins reduces seed longevity in Arabidopsis thaliana (2011, background): “The seeds of the Arabidopsis vte (vitamin E) mutants, which are deficient in several forms of tocopherols, lipophilic antioxidants, exhibit decreased germination compared to wild-type seeds after accelerated ageing for 3 d at 408C and 100% relative humidity (RH) (Sattler et al., 2004).”
Age-related biochemical changes during storage of beech (Fagus sylvatica L.) seeds (2007, background): “However, recent investigations of Sattler et al. (2004) with mutants of Arabidopsis thaliana, lacking synthesis of tocopherols in seeds, showed that vitamin E is essential for seed longevity.”
Vitamin synthesis in plants: tocopherols and carotenoids. (2006, background): “Indeed, the only well-defined tocochromanol function in plants to date is the protection of seed-storage lipids from oxidation during dormancy and germination in Arabidopsis (106).”
Increased α-tocopherol content in soybean seed overexpressing the Perilla frutescens γ-tocopherol methyltransferase gene (2006, background): “Seed germination and seedling development are an oxidative bottleneck for plants in which tocopherols play an essential role ( Sattler et al. 2004 ).”
Prolonging the longevity of ex situ conserved seeds by storage under anoxia (2014, background): “The importance of tocopherols for seed survival has been demonstrated by the strongly reduced seed longevity of a tocopherol-deficient Arabidopsis mutant (Sattler et al., 2004).”
First off the mark: early seed germination. (2011, background): “In addition, the lipophilic antioxidant tocopherol, which protects membranes from lipid peroxidation, is essential for seed longevity and germination characteristics, as was shown in a mutant approach in Arabidopsis (Sattler et al., 2004; Mene-Saffrane et al., 2010).”
Response and effect traits of arable weeds in agro‐ecosystems: a review of current knowledge (2017, background): “However, oily seeds have to prevent oxidation of their energy stores during seed dormancy, a process that could reduce seed longevity (Sattler et al., 2004) or need thicker and less permeable seed coats.”
