    Abstract:
    Zea mays ssp. mays is one of the world's most important crop plants, boasting a multibillion dollar annual revenue. In addition to its agronomic importance, maize has been a keystone model organism for basic research for nearly a century. Within the cereals, which include other plant model species such as rice (Oryza sativa), sorghum (Sorghum bicolor), wheat (Triticum spp.), and barley (Hordeum vulgare), maize is the most thoroughly researched genetic system. Several attributes of the maize plant, including a vast collection of mutant stocks, large heterochromatic chromosomes, extensive nucleotide diversity, and genic colinearity within related grasses, have positioned this species as a centerpiece for genetic, cytogenetic, and genomic research. As a model organism, maize is the subject of such far-ranging biological investigations as plant domestication, genome evolution, developmental physiology, epigenetics, pest resistance, heterosis, quantitative inheritance, and comparative genomics. These and other studies will be advanced by the completed sequencing and annotation of the maize gene space, which will be realized during 2009. Here we present an overview of the use of maize as a model system and provide links to several protocols that enable its genetic and genomic analysis.
