Database Description

The Maize Genetics and Genomics Database (MaizeGDB) is a central repository for maize sequence, stock, phenotype, genotypic and karyotypic variation, and chromosomal mapping data. In addition, MaizeGDB provides contact information for over 2,400 maize cooperative researchers, facilitating interactions among members of the rapidly expanding maize community. MaizeGDB represents the synthesis of all data available previously from ZmDB and from MaizeDB - databases that have been superseded by MaizeGDB. MaizeGDB provides web-based tools for ordering maize stocks from several organizations including the Maize Genetics Cooperation Stock Center and the North Central Regional Plant Introduction Station (NCRPIS). Sequence searches yield records displayed with embedded links to facilitate ordering cloned sequences from various groups including the Maize Gene Discovery Project and the Clemson University Genomics Institute (CUGI). An intuitive web interface is implemented to facilitate navigation among related data, and analytical tools are embedded within data displays. Web-based curation tools for both designated experts and general researchers facilitate community-aided data acquisition.

Recent Developments

MaizeGDB is actively expanding the scope of the database to include novel data types. For example, MaizeGDB now includes chromosome images from cytogenic FISH mapping.


MaizeGDB is funded by the USDA-ARS Specific Cooperative Agreement No. 58-3625-1-192.
