Meiotic Genes and Meiosis in Maize

Meiosis is the specialized cell division required to produce gametes with a haploid chromosome content in all eukaryotes with a sexual cycle. The cellular events that occur in meiosis are evolutionarily conserved, as are many of the proteins associated with meiosis, especially those required for homologous recombination. Maize stands out as one of the premier cytological model organisms for studying meiosis because of its large, well defined chromosomes, the ease in which meiotic stages can be identified cytologically, and its many genetics resources. Powerful forward genetics screens have led to the identification of a large number of maize meiotic mutants although only a few of them have been cloned. In this chapter, we describe the mutant collection, major findings associated with working with these mutants, and the promise of maize cytogenetics for future research.
