New way to produce high-vitamin corn could improve nutrition in developing countries
Date:1/17/2008

rely by visual inspection. "Therefore, identifying crops that have high levels of vitamin A precursors has traditionally been like finding a needle in a haystack."

But the team led by Buckler and Rocheford has significantly simplified the task of sifting through that proverbial haystack. They did so by identifying genetic markers in corn that are associated with high levels of vitamin A precursors. These markers can be used by "scientists working in very basic labs in developing countries to quickly screen for local corn strains that are high in vitamin A precursors," says Buckler. Then, these high-vitamin strains may be bred, cultivated and consumed by local people.

Corn is the dominant subsistence crop in sub-Saharan Africa and Latin America, where 17 to 30 percent of children under age five are vitamin A deficient, says Buckler. Because corn is consumed for all three meals a day in much of Africa, it is a good target for vitamin biofortification, he added.

Buckler says that his team's method for analyzing the genetic makeup of corn is "much simpler and faster and up to 1,000-fold cheaper" than running the types of chemical tests that were previously available for identifying corn high in vitamin A precursors. He expects it to significantly accelerate the vitamin biofortification of corn crops.

The Buckler and Rocheford team is currently working with various international organizations, such as CIMMYT (the International Maize and Wheat Improvement Center) and the International Institute for Tropical Agriculture, to help train plant breeders in developing countries to use their techniques.

Buckler says that this new method of increasing cultivation of high-vitamin corn was made possible by recent breakthroughs in statistical analyses and the advent of rapid DNA sequencers -- instruments that are used to automate genetic profiling of crops. The researchers expect this new method to have broad applications beyond corn imp
