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: 00.029.0.01.003. Virus accession number: 29001003. Obsolete virus code: 29.0.1.0.003; superceded accession number: 29010003.
NCBI Taxon Identifier NCBI Taxonomy ID: 10820.

Name, Synonyms and Lineage

Synonym(s): Australian wheat striate mosaic virus. ICTV approved acronym: CSMV. Virus is an ICTV approved species of the genus 00.029.0.01. Mastrevirus in the family 00.029. Geminiviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid is elongated and exhibits icosahedral symmetry. The capsid is geminate and has a diameter of 18 nm. With a length of 30 nm (Hatta and Francki, 1979).

Electron microscopic preparation and references: Virus preparation contains many virions. Use UA not PTA-H. Reference for electron microscopic methods: Francki et al. (1979).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.35 g cm-3 (after fixation in glutaraldehyde). There are 1 sedimenting component(s) found in purified preparations.

Nucleic Acid

The Mr of the genome constitutes 19% of the virion by weight. The genome is not segmented and contains a single molecule of circular, ambisense, single-stranded DNA. The complete genome is 2750 nucleotides long. The DNA is fully sequenced, complete sequence is 2750 nucleotides long. Sequence has the accession number

[M20021] Em(40)_vi:GECHMGEN Gb(84)_vi:CHMGEN Chloris striate mosaic virus DNA, complete genome. 7/89 2,750bp. 1 sequence. "]

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to bean golden mosaic virus, cassava African mosaic virus (Francki et al., 1979, 1980).

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.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is possibly transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Cicadellidae; Nesoclutha (obscura) pallida. Virus is transmitted in a persistent manner.

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, Chloris gayana, Dactylis glomerata, Eleusine coracana, Hordeum vulgare, Ixophorus unisetus, Triticum aestivum, Zea mays.

Host:
Experimentally infected hosts mainly show symptoms of chlorotic streaks.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chloris gayana, Hordeum vulgare — yellow or grey streaks.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Chloris gayana — for maintaining cultures by vegetative propagation, the leaves are a good source of virus.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chloris gayana (W) and the vector Nesoclutha pallida assayed by feeding on Chloris gayana (Grylls and Waterford, 1976; Francki et al., 1979).

References to host data: Grylls (1963).

Histopathology: Virus can be best detected in leaves, mesophyll, meristem and phloem (Francki et al., 1979). Virions are found in the sometimes cytoplasm, nucleus, and cell vacuole (Francki et al., 1979).

Geographical Distribution

The virus occurs in Australia.

List of Strains and Isolates in the Species

Chloris (C) and Microlaena.
