Natural gene selection can produce orange corn rich in provitamin A
Researchers have identified a set of genes that can be used to naturally boost the provitamin A content of corn kernels, a finding that could help combat vitamin A deficiency in developing countries and macular degeneration in the elderly. Professor of agronomy Torbert Rocheford and fellow researchers of Purdue University, USA, found gene variations that can be selected to change nutritionally poor white corn into bio-fortified orange corn with high levels of provitamin A carotenoids. Their study provides the genetic blueprint to quickly and cost-effectively convert white or yellow corn to orange corn that is rich in carotenoids, by using natural plant breeding methods, not transgenics.
