DPVweb database of plant viruses

DPVweb database of plant viruses provides a curated repository of genomic sequences and taxonomic information for viruses, viroids, and satellites affecting plants, fungi, and protozoa to support comparative and evolutionary genomic analyses.

Key Features:

• Organism and genome scope: Covers viruses, viroids, and satellites infecting plants, fungi, and protozoa.
• Sequence collection: Contains approximately 9,000 complete or partially complete viral, viroidal, and satellite sequences.
• Feature annotation: Sequence entries include curated annotations of gene features, non-translated regions, and other genetic elements with precise start and end positions.
• Taxonomic descriptions: Provides concise descriptions of each virus family and genus alongside classified lists of viral sequences.
• Representative species coverage: Includes a single representative sequence from all fully sequenced virus species with RNA or single-stranded DNA genomes.
• Nomenclature standardization: Standardizes gene and protein names within genera and families wherever possible.
• Data format: Sequence entries include FASTA-format sequences.

Scientific Applications:

• Comparative genomics: Enables comparative genomic studies across plant, fungal, and protozoan viruses and across RNA and single-stranded DNA viral species.
• Evolutionary and virology research: Supports evolutionary biology and virology investigations through representative species and curated sequence data.
• Genomic analyses: Provides curated sequences and precise feature annotations for genomic analyses.
• Domain-specific research: Serves as a resource for researchers in plant pathology, mycology, and protozoology.

Methodology:

Manually curated sequence annotations specifying gene features, non-translated regions, and precise start/end coordinates, with nomenclature standardized within genera and families.
