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: 01.062.0.05.004. Virus accession number: 62005004. Obsolete virus code: 62.0.5.0.004; superceded accession number: 62050004.
NCBI Taxon Identifier NCBI Taxonomy ID: 279896.

Name, Synonyms and Lineage

Synonym(s): virus del enanismo rayado maiz, maize stripe Indian virus (Sharma and Payak, 1983), sorghum chlorosis virus, zea mays virus. ICTV approved acronym: MMV. Virus is an ICTV approved species of the genus Nucleorhabdovirus in the family 01.062. Rhabdoviridae; order 01. Mononegavirales.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. Virus capsid is enveloped. Virions are bullet-shaped. Virions measure 90 nm in diameter (48m in thin sections, 225 nm in length (242 nm in thin sections). Capsid/nucleocapsid is elongated and exhibits helical symmetry.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Lastra and Acosta (1979).

Physicochemical and Physical Properties

Virions have a buoyant density in sucrose of 1.181 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 774 S20w. The infectivity is lost when deproteinized with proteases; lost when deproteinized with phenol or detergent.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear single-stranded RNA. Minor species of non-genomic nucleic acid are also found in virions. The encapsidated nucleic acid is mainly of genomic origin, but virions may also contain subgenomic RNA that is mRNA. The complete genome is 12540 nucleotides long, is sequenced, complete sequence is about 12540 nucleotides long. Reference to nucleotide sequence Lastra and Acosta (1979).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 5 structural protein(s).

Structural Proteins: Reference to method of preparation: Autrey (1983, Falk and Tsai (1983).

Lipids

Lipids are present. The lipids are of host origin.

Genome Organization and Replication

By itself, genomic nucleic acid is not infectious; a successful infection by the virus requires virus protein(s) (probably a polymerase).

Transcription: Sub-genomic RNA is present in infected cells; encoding the coat protein (N protein).

Translation: Coat protein mRNA is translated in probably in cytoplasm.

The genome replicates in the nucleus.

Replication cycle Virions accumulate in the cell nucleus.

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; not transmitted by contact between hosts; not transmitted by seeds; not transmitted by pollen.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Delphacidae; Peregrinus maidis. Virus is transmitted in a persistent manner; retained when the vector moults; replicates in the vector; not 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: Rottboellia exaltata, Setaria vulpiseta, Sorghum bicolor, Zea mays.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Zea mays.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Zea mays (W).

Histopathology: Virus can be best detected in all parts of the host plant. Virions are found in the perinuclear space (and the cores bud through the inner nuclear membrane).

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Inclusions are aggregates. Inclusions contain mature virions.

Geographical Distribution

The virus occurs in possibly Australia, Colombia, Costa Rica, Fiji, India, Mauritius, Mexico, Peru, Spain, Tanzania, and the United States of America (and the Caribbean Islands).
