Vitamin E Discovery in Maize could Lead to More Nutritious Crop

It could improve the nutritional profile of this staple crop.


Maize, also known as corn, is higher in energy density and starch content and has a slower rate of rumen fermentation. It contains healthy nutrients, high amounts of insoluble fiber, etc.

A new research discovered the genes that control vitamin E content in maize grain. It is believed that the findings could improve the nutritional profile of this staple crop.

Scientists identified 14 genes across the genome that were involved in the synthesis of vitamin E. Six of them were unknown, but encode proteins that contribute to a class of antioxidant compounds called tocochromanols, collectively known as vitamin E.

The tocochromanols offers good heart health in humans and proper functioning in plants.

Michael Gore, associate professor of plant breeding and genetics said, “We have established a near-complete foundation for the genetic improvement of vitamin E in the grain of maize and other major cereals.”
