Tocopherol Content of Soybean Lines with Mid-oleate and 1%-Linolenate

Genetic variation of g-tocopherol methyltransferase gene contributes to elevated a-tocopherol content in soybean seeds

Background: Improvement of a-tocopherol content is an important breeding aim to increase the nutritional value of crops. Several efforts have been conducted to improve the a-tocopherol content in soybean [Glycine max (L.) Merr.] through transgenic technology by overexpressing genes related to a-tocopherol biosynthesis or through changes to crop management practices. Varieties with high a-tocoph...

Gamma Tocopherol Content of Iranian Sesame Seeds

Gamma tocopherol content of 7 Iranian sesame seeds (sesamum indicum L.) was determined by high performance liquid chromatography using C8 column and methanol, water and butanol as mobile phase. The gamma-tocopherol content varied from 563 to 1095 mg/kg in oil and 293 to 569 mg/kg in sesame seed and was in broad agreement with the Codex range. A large variation was found in the concentration of ...

Oxidative Stress Affects [alpha]- Tocopherol Content in Soybean Embryonic Axes upon Imbibition and following Germination.

The content of [alpha]-tocopherol ([alpha]T) in isolated soybean (Glycine max, var Hood) embryonic axes was measured upon germination. Dry, high-vigor axes contained 1.2 [plus or minus] 0.1, nmol/axis and after an increase during the initial 6 h of imbibition, there was a decline to 1.0 [plus or minus] 0.1 nmol/axis at 24 h of incubation. Incubation in the presence of the redox-cycling agent pa...
