Rodney NCBI Viral Genomes Resource 2015-01-28 .txt text/plain 3863 186 37 This, in turn, has placed increased emphasis on leveraging the knowledge of individual scientific communities to identify important viral sequences and develop well annotated reference virus genome sets. Whereas primary databases are archival repositories of sequence data, reference databases provide curated datasets that enable a number of activities, among them are transfer annotation to related genomes (11) (12) (13) , sequence assembly and virus discovery (14) (15) (16) (17) , viral dynamics and evolution (18) (19) (20) and pathogen detection (14, (21) (22) (23) . The second model captures and standardizes host information for all viruses, and whenever a new RefSeq record is created, a manually curated 'viral host' property is assigned to the relevant species within the NCBI Taxonomy database.
