Vitamin E find paves way for ‘more nutritious’ maize

SLAMABAD: A new research from the Cornell University has identified genes that control vitamin E content in maize grain, a finding that could lead to improving the nutritional profile of this crop, Health News reported.

Researchers combined different types of genetic association analysis to identify 14 genes across the genome that were involved in the synthesis of vitamin E. Six genes were newly discovered to encode proteins that contribute to a class of antioxidant compounds called tocochromanols, collectively known as vitamin E.

Along with antioxidant properties, tocochromanols have been associated with good heart health in humans and proper functioning in plants.

Co-corresponding author Michael Gore revealed that they have established a near-complete foundation for the genetic improvement of vitamin E in grain of maize and other major cereals.

“There has been talk, among breeders working to increase pro vitamin A in maize, that we could increase vitamin E at the same time,” said first author Christine Diepenbrock.

She added, “They are related compounds biochemically, and tocochromanols are essential for seed viability in that they prevent seed oils from going rancid throughout seed storage, germination and early seedling development.
