Abstract
MaizeDB (http://www.agron.missouri.edu/) has existed since the early 90’s as a genomespecific database that is grounded in genetic maps, their documentation and annotation. The database management system is robust and has continuously been Sybase. In this brief review we provide an introduction to the database as a functional genomics tool and new accesses to the data: 1) probe tables by bin location 2) BLAST access to map data 3) cMap, a comparative map graphical tool.
