Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. Virus preparations contain one particle component, or more than one particle component. The capsid is filamentous, flexuous; with a clear modal length, or clear predominate lengths with a length of 680-900 nm, or 500-600 nm; 200-300 nm and a width of 12-15 nm. Pitch of helix is 3.4 nm.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.26-1.34 g cm-3.

Nucleic Acid

The Mr of the genome constitutes 5% of the virion by weight. The genome is linear, positive-sense, single-stranded RNA. The complete genome is 8500-10000 nucleotides long. The 5'-end of the genome has a genome-linked protein (VPg). The 3'-terminus has a poly (A) tract. The multipartite genome is divided among more than one type of particle and the segments are distributed between 2 different types of particles.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 95% of the particle weight.

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are not reported.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae), or Liliopsida (Monocotyledonae).

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses by Dr Cornelia Büchen-Osmond is written in DELTA. The virus descriptions in ICTVdB are coded by, or using data from experts in the field of virology or members ICTV. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations are automatically generated and formatted for display on the Web from the descriptions in DELTA-format. The description has been generated automatically from DELTA files.
