RESEARCH-PGR: A Genome-level Approach to Balancing the Vitamin Content of Maize Grain

This collaborative research project is directed at identifying a subset of the ~40,000 genes in the corn genome that work together to determine the levels of five essential and limiting dietary vitamins in kernels: vitamin E and the four B vitamins, B1 (thiamin), B2 (riboflavin), B3 (niacin) and B6 (pyridoxine). By combining approaches similar to those used in the Human Genome project, the researchers will identify alleles, special variations in these "vitamin" genes, and learn how to put them together to generate high amounts of vitamins in corn kernels.
