DPVweb is an aid to researchers in the field of plant virology as well as an educational resource for students of virology and molecular biology.. The site provides a single point of access for all known plant virus genome sequences making it easy to collect these sequences together for further analysis and comparison.
Geminiviridae is a family of plant viruses that encode their genetic information on a circular genome of single-stranded (ss) DNA. There are 520 species in this family, assigned to 14 genera. There are 520 species in this family, assigned to 14 genera.
The tomato chlorosis virus (ToCV) is an RNA virus belonging to the genus crinivirus, a group of plant-infecting viruses in the family Closteroviridae. [ 1 ] Tomato chlorosis virus (ToCV) was originally discovered in the mid-1990s in greenhouse-grown tomato plants in north-central Florida, USA. [ 2 ]
Plant viruses can be pathogenic to vascular plants ("higher plants"). Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely have an envelope. The great majority have an RNA genome, which is usually small and single stranded (ss), but some ...
Caulimoviridae is a family of viruses infecting plants. [1] There are 94 species in this family, assigned to 11 genera. [2] [3] Viruses belonging to the family Caulimoviridae are termed double-stranded DNA (dsDNA) reverse-transcribing viruses (or pararetroviruses) i.e. viruses that contain a reverse transcription stage in their replication cycle.
Tobacco etch virus (TEV) is a plant virus in the genus Potyvirus and family Potyviridae. [1] Like other members of the genus Potyvirus, TEV has a monopartite positive-sense, single-stranded RNA genome surrounded by a capsid made from a single viral encoded protein. The virus is a filamentous particle that measures about 730 nm in length.
Aphid species Myzus persicae. The cauliflower mosaic virus (CaMV) is a member of the family Caulimoviridae.This family is grouped together with the Belpaoviridae, Metaviridae, Pseudoviridae, and Retroviridae (all of which instead have an RNA genome replicated via a DNA intermediate) in the order Ortervirales; the Hepadnaviridae, despite having a DNA genome replicated via an RNA intermediate ...
The coat protein of TSV plays an important role in its life cycle. It protects the viral genome and plays a role in cell to cell movement. [4] Once the virus becomes systemic, it can be transmitted by vectors. TSV requires a living plant to survive for a period of time. The virus may be transmitted by thrips vector, mechanical damage, pollen or ...
