A search database for rice reverse genetics. OryGenesDB contains flanking sequence tags of various mutagens and functional genomics data, collected from both international insertion collections and the literature. OryGenesDB is also a user-oriented web application that automates and organizes web queries in rice functional genomics. Users can run their queries and store the output and update the results as the source databases are continuously independently updated. OryGenesDB offers a way to accelerate the manual process of integrating and compiling data from heterogeneous sources.
