Name, Synonyms and Lineage

Virus is an ICTV approved species of the genus 81.001.4. single-stranded RNA Satellite Viruses; family 81. Satellites.

Virion Properties

Nucleic acid is not encapsidated and virus relies for encapsidation on a helper virus.

Virion Properties

Morphology

Satellite capsid is isometric and exhibits icosahedral symmetry with a diameter of 30-35 nm. Capsids appear round.

Electron microscopic preparation and references: Reference for electron microscopic methods: Gingery and Louie (1984).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.355 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 47 S20w.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, single-stranded RNA is recovered. The genome is fully sequenced and complete sequence is 1168 nucleotides long. Sequence has the accession number [M55012] Em(40)_vi:SVMSECG Gb(84)_vi:SVMSECG Satellite virus of maize white line mosaic virus ORF, complete cds. 2/91 1,168bp. 1 sequence.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins. Virions consist of 1 structural protein(s).

Antigenicity

The virus does not show serological relationships to panicum mosaic satellite and tobacco necrosis satellite viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

Transmission and Vector Relationships

Probably in soil.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Gramineae. The following species were susceptible to experimental virus infection: Zea mays.

Histopathology: Virus can be best detected in leaves and roots. Virions are found in the cytoplasm.

Cytopathology: Inclusions are not present in infected cells.

Geographical Distribution

The virus occurs in France and the United States of America (Ohio).
