NCBI Taxon Identifier NCBI Taxonomy ID: 12331.

Name, Synonyms and Lineage

Synonym(s): ine shima-ha gare uirusu. ICTV approved acronym: RSV. Virus is the type species. Virus is of the genus 00.069.0.01. Tenuivirus; not assigned to a family.

Virion Properties

Morphology

Virions consist of a nucleocapsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. Virus preparations contain more than one particle component. The nucleocapsid is filamentous, flexuous, or spiral, or branched, or circular, or tightly coiled; and segments have a length proportional to the size of their RNA and a width of 8 nm. Axial canal is distinct (canal- like structures are seen in some virions). Basic helix is obvious. The nucleocapsid is segmented.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Toriyama (1982a).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.282 g cm-3 (not fixed with aldehydes). There are 4 sedimenting component(s) found in purified preparations (T, M1, M2, B and nB). The sedimentation coefficient is 98 S20w (nB, of the other(s) are 68 S20w (M), or 80 S20w (B). Isoelectric point pH is 4.5. The thermal inactivation point (TIP) is at 50-55°C. The longevity in vitro (LIV) is 4 days in extracts of viruliferous insects kept at 4°C, 8-12 months in viruliferous insects and diseased rice plants at -20°C and 1-2 months in purified preparations at -20°C. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3-4 (from plants, 10-4 to 10-5 from viruliferous insects).

Nucleic Acid

The Mr of the genome constitutes 12% of the virion by weight. The genome is segmented and consists of four segments of linear, negative-sense and ambisense, single-stranded RNA, is fully sequenced, or partially sequenced, complete sequence is 9000 nucleotides long. Sequence has the accession number

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 transmitted by mechanical inoculation (but only with great difficulty, not transmitted by contact between hosts; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Delphacidae; Laodelphax striatellus, Terthron albovittatum, Unkanodes sapporona, U. albifascia. 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: Avena sativa, Cynodon dactylon, Dactylis glomerata, Digitaria adscendens, Digitaria violascens, Eragrostis multiflorum, Hordeum vulgare, Lolium perenne, Oryza sativa, Oryza sativa var. japonica, Phleum pratense, Secale cereale, Setaria italica, Setaria viridis, Triticum aestivum, Zea mays.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Gramineae. Species inoculated with virus that do not show signs of susceptibility: Anthoxanthum odoratum, Echinochloa crus-galli, Elymus tsukushiensis var. transiens, Festuca arundinacea, Phalaris arundinacea, Poa pratensis.

Diagnostic Hosts

Diagnostic host species and symptoms:

Oryza sativa (Japonica type), Triticum aestivum, Zea mays — chlorotic stripe and pale streaking. Diagnostic host: insusceptible host species Anthoxanthum odoratum, Elymus tsukushiensis var. transiens, Festuca arundinacea, Phalaris arundinacea, Poa pratensis.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Oryza sativa Japonica type varieties, Triticum aestivum, Zea mays.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Oryza sativa japonica type cvs Norin 8, Kinmaze, Triticum aestivum, Zea mays cv. Golden Cross Bantam, all (W).

References to host data: Iida (1969, Toriyama (1983a).

Histopathology: Virus can be best detected in epidermis. Virions are found in the nucleus (rarely), or cytoplasm.

Cytopathology: Inclusions are present in infected cells. Cytoplasmic inclusions are crystals and amorphous X-bodies. Inclusions do not contain mature virions.

Geographical Distribution

The virus spreads in East Asia. The virus occurs in China, Japan, Taiwan, and the USSR (former).
