This site provides a central source of information about viruses, viroids and satellites of plants, fungi and protozoa, with some additional data on animal viruses and phages with RNA or ssDNA genomes. The regular updating of information is assisted by sponsorship from the Zhejiang Academy of Agricultural Sciences, Hangzhou, People's Republic of China.
** NOW UPDATED WITH THE LATEST (FEBRUARY 2013) ICTV TAXONOMY! **

An introductory overview of plant viruses, their importance, transmission and classification.
Over 400 individual descriptions of plant viruses or virus groups. Nos 1-354 were originally published
in paper form by the Association of Applied Biologists (AAB) between 1970 and 1989, while additional
descriptions have been added to a CD-ROM (also published by the AAB) since 1998. These can now be accessed
from the indexes in the DPV menu or from the Taxonomy pages. New descriptions are being commissioned and will be added as they become available.
A brief description is provided for each genus and family. This includes all viruses, viroids and satellites infecting plants, fungi and protozoa and additionally all other RNA and ssDNA viruses infecting animals. The genome organisation is described wherever this is known and there are links to a genome map and a representative electron micrograph (for plant viruses only). Lists of species with their acronyms and synonyms are provided for each genus. There are also links to the plant virus Descriptions (DPVs) and to the nucleotide sequences.
We provide the accession numbers used by EMBL and Genbank databases for all the sequences of viruses, satellites and viroids infecting plants, fungi and protozoa. These have been checked to ensure that, as far as possible, they are allocated here to their correct name and the list is updated at least once every two months.
We have constructed a sequence feature database (DPVweb) that contains all sequences of viruses, viroids and satellites of plants, fungi and protozoa, that are complete or which encode one or more gene. The database also includes verified annotations for the open reading frames and other major features. To assist comparisons with related viruses, there are also representative sequences for every completely sequenced animal virus with an RNA or ssDNA genome. Sequence features (genes etc.) can be selected and downloaded in FASTA format (nucleotide sequence and, where appropriate, the amino acid sequence). This can be done either by following the links to Curated Sequences from the Notes pages or by using the software provided.
We are developing software to use this database as a resource for the analysis of plant virus sequences, and this will be made available through these web pages. We have begun by providing software to analyse Codon Use and Transmembrane Domains and hope to add other types of analysis in due course. We would welcome approaches from potential collaborators to help us enhance these facilities.
We also provide some pages that summarise the polyprotein cleavage sites used in the family Potyviridae. This information is based on published data and our own analyses as reported in the paper: Adams, Antoniw & Beaudoin (2005). Overview and analysis of the polyprotein cleavage sites in the family Potyviridae. Molecular Plant Pathology 6, 471-487.
