Overview for Zea mays (Maize)

Zea mays (also called corn or maize) has the highest world-wide production of all cereal crops, ahead of wheat and rice. Over 60% of the harvest is processed into corn silage and fed to livestock. In addition, corn has become a staple food in many parts of the world and it is used as a renewable raw material for the production of bioethanol and biogas. Maize is not only of economic value, but also an important model organism for studies on plant genetics, physiology and development. It has a large genome of about 2.4 gigabases. In agReg-SNPdb, we store 44,289 genes and 48,830,598 SNPs.
