Classification

This is a description of a plant virus at the species level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 00.060.0.07.001. Virus accession number: 60007001. Obsolete virus code: 60.0.7.1.001; superceded accession number: 60071001.
NCBI Taxon Identifier NCBI Taxonomy ID: 77698.

Name, Synonyms and Lineage

ICTV approved acronym: FDV. Virus is the type of the genus 00.060.0.07. Fijivirus in the family 00.060. Reoviridae.

Virion Properties

Morphology

Virions consist of a capsid, a core, and a nucleoprotein complex. Virus capsid is not enveloped. Capsid/nucleocapsid is isometric with icosahedral symmetry and has a diameter of 71 nm (intact virions), or 54 nm (subvirions (ie. core)). The capsid shells of virions are composed of two layers. All shells are usually present. Capsids appear round. The capsid surface structure reveals a regular pattern with distinctive features. The capsomer arrangement is not obvious. Surface projections are distinct spikes protruding from the 12 vertices. Inner capsids consist of a 55 nm consists of a rough shell (showing B-type spikes, about 8 nm long and 12 nm in diameter). Virus preparations contain one particle component. The core is spherical with a diameter of 35-40 nm.

Only one species is recovered in preparations. Incomplete particles are common. They are disintegrated particles.

Electron microscopic preparation and references: Virus preparation contains galls many virions, or few virions (in leaves). Stain with UA. Reference for electron microscopic methods: Van der Lubbe et al. (1979).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations.

Nucleic Acid

The genome is monomeric; segmented and consists of ten segments of linear double-stranded RNA. The complete genome is 27109 nucleotides long. RNA-1 is fully sequenced and complete sequence is 3998 nucleotides long, is sequenced and complete sequence is about 3385 nucleotides long, is sequenced, but only an estimate is given, complete sequence is 3380 nucleotides long, has been sequenced, but only an estimate is provided; complete sequence is 33800 nucleotides long and has been sequenced, but only an estimate is presented, complete sequence is 3100 nucleotides long. RNA-6 has been fully sequenced, complete sequence is 2500 nucleotides long. RNA-7 has been sequenced, but only an estimate is presented, complete sequence is 2190 nucleotides long. RNA-8 has been sequenced, complete sequence is about 1732 nucleotides long. RNA-9 has been sequenced, but only an estimate is available, complete sequence is 1724 nucleotides long. RNA-10 has been sequenced, but only an estimate is available; complete sequence is 1720 nucleotides long. The 5'-terminal sequence has conserved regions. The 3'-terminus has conserved nucleotide sequences; in species of same genus; in all RNA species. The multipartite genome is found in one type of particle only. Each virion contains a single copy of the genome; a full length copy.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of at least 3 structural protein(s) (in the core).

Structural Proteins: Reference to method of preparation: Van der Lubbe et al. (1979).

Lipids

Lipids are absent.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is not transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Delphacidae; Perkinsiella saccharicida, P. vitiensis and P. vastatrix. Virus is transmitted in a persistent manner; retained when the vector moults; replicates in the vector; transmitted congenitally to the progeny of the vector.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in few families. Susceptible host species are found in the Family Gramineae. The following species were susceptible to experimental virus infection: Saccharum officinarum, Sorghum bicolor, Zea mays.

Diagnostic Hosts

Diagnostic host species and symptoms:

Saccharum ssp., Sorghum ssp., Zea mays — enations on deformed leaves and leaf sheaths.

References to host data: Hutchinson et al. (1972).

Histopathology: Virus can be best detected in gall tissue. Virions are found in the cytoplasm and cell vacuole.

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Inclusions are round, containing strands and amorphous material. Inclusions contain mature virions. Other cellular changes include proliferations in both phloem and xylem.

Geographical Distribution

The virus spreads in Africa and Australasia and Pacific Islands (New Britain and the New Hebrides). The virus occurs in Australia, Fiji, Papua New Guinea, the Philippines, Thailand, and Samoa. The virus is found, but with no evidence of proliferation, in the U.S.A.
