ICTVdB Virus Code: 00.088.0.81.003. Virus accession number: 88001003. Obsolete virus code: 00.027.0.81.011; 27.0.1.T.011; superceded accession number: 27081011; 2701t011.

Name, Synonyms and Lineage

ICTV approved acronym: RSNV. Virus is now a tentative member of the genus 00.088.0.01. Benyvirus, but was considered a 00.027.0.01. Furovirus (until 2002 Reference: Morales, J.F., Lozano, I., Castano, M., Arroyave, J.A., and Adams, M.J. Emergence and partial characterization of rice necrosis virus in the Americas.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. Virus preparations contain more than one particle component. The capsid is rod-shaped with a clear modal length with a length of 110-160 nm, or 270-380 nm and a width of 20 nm.

Electron microscopic preparation and references: Reference for electron microscopic methods: Fauquet and Thouvenel (1983).

Physicochemical and Physical Properties

There are 3 sedimenting component(s) found in purified preparations. The thermal inactivation point (TIP) is at more than 50°C.

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. The multipartite genome is divided among more than one type of particle.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to Beet necrotic yellow vein, Nicotiana velutina mosaic and Peanut clump viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Class Liliopsida (Monocotyledonae)
Subclass COMMELINIDAE; Order Poales;
Family Poaceae. Virus found in Oryza sativa.

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; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by fungi; Polymyxa graminis.

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 Chenopodiaceae, Gramineae, Solanaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Nicotiana benthamiana, Oryza sativa.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium amaranticolor — chlorotic local lesions.

Nicotiana benthamiana — necrotic ringspots.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chenopodium amaranticolor (L).

References to host data: Fauquet and Thouvenel (1983).

Geographical Distribution

The virus spreads in Africa and South and Central Americas. The virus occurs in Cote d'Ivoire.
