Database Description

The NCBI Viral Genomes Resource ( provides sequence information, as well as precomputed comparative analyses and Web tools, for all viruses and viroids for which (nearly) complete genomic sequences have been established and deposited to DDBJ, EMBL, or GeneBank. The collection currently contains over 2200 reference sequences (RefSeq) and about 6,500 additional complete sequences for more than 1,500 different viral species. The reference sequences are maintained in separate records that are further curated and updated. Whenever more than one complete genome for a species is available, a pairwise global alignment of a reference sequence with each additional sequence is provided. Precomputed clusters of related proteins (VOG) from the reference sequences help navigate among viral proteomes and summarize available functional information for most major virus groups. The data are accessible via Entrez as well as from specialized Web pages offering visualization of the sequence information at various levels of detail.


The NCBI Viral Genomes Resource is a collaborative effort between NCBI staff and many dedicated scientists worldwide.
