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 3-4 nm. The nucleocapsid is segmented.

Electron microscopic preparation and references: Reference for electron microscopic methods: Gingery et al. (1981).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.28 g cm-3. There are usually 4 sedimenting component(s) found in purified preparations (sometimes more). The sedimentation coefficient is 187 S20w.

Nucleic Acid

The Mr of the genome constitutes 5.2% of the virion by weight (~0.3). The genome is segmented and consists of five segments of linear, negative-sense and ambisense, single-stranded RNA. The complete genome is 18600 nucleotides long. RNA-1 is fully or partially sequenced. Complete sequence is 9120 nucleotides long. Sequence has the accession number

Proteins

Proteins constitute about 94.8% of the particle weight.

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

Non-Structural Proteins: Virus-coded non-structural proteins have been isolated and 1 non-structural protein(s) are found.

Lipids

Lipids are not reported.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Antigenicity

The virus is serologically related to rice stripe virus is closely related; rice grassy stunt virus is distantly related. The virus does not show serological relationships to rice hoja blanca and European wheat striate mosaic viruses.

The maize stripe virus reported from India (Raychaudhuri et al., 1977) is maize mosaic virus (Sharma and Payak, 1983).

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 (chlorosis becomes progressively more severe).

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; transmitted congenitally to the progeny of the vector (via eggs).

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: Hordeum vulgare, Rottboellia exaltata, Secale cereale, Sorghum bicolor, Zea mays.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Gramineae. Species inoculated with virus that do not show signs of susceptibility: Avena sativa, Chloris gayana, Eleusine coracana, Oryza sativa, Saccharum officinarum, Triticum aestivum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Rottboellia exaltata, Zea mays — systemic chlorotic striping, apical bending.

Sorghum bicolor — variable. Diagnostic host: insusceptible host species Avena sativa, Oryza sativa, Triticum aestivum.

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).

References to host data: Gingery et al. (1981, Greber (1981).

Histopathology: Virus can be best detected in mesophyll and phloem. Virions are found in the cytoplasm.

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Inclusions are amorphous, semi-opaque, and filamentous electron dense laminated aggregates. Inclusions do not contain mature virions (apparently the filamentous electron dense inclusions contain non-capsid protein. No nucleoprotein has been shown in either type of inclusion). Other cellular changes include induction of smaller vacuoles and increasing amounts of electron dense cytoplasm after 4-5 weeks apparently due to the large volume of amorphous semi-opaque inclusions.

Geographical Distribution

The virus occurs in Australia, Botswana, Guadeloupe, India, Kenya, Mauritius, Nigeria, Peru, the Philippines, Reunion, Sao Tome and Principe, the United States of America, and Venezuela.
