Secondary database construction is an important subject in the field of bioinformatics. As the full genomic sequences of some organisms are being completed and followed by structural and functional studies, construction of secondary database becomes essential on the agenda. The rice dwarf virus (RDV) is a pathogen infecting rice in China, Japan and the Southeastern Asia region and leading to considerable economic loss. Based on the data generated from recent genomic research and earlier biochemical studies scattered in various primary databases and scientific journals, we have constructed a compact, user-friendly and non-redundant job-oriented secondary database. This work will provide compiled useful information for plant molecular biologists as well as in achieving preliminary experiences in secondary database construction.
