Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 28-30 nm. Capsids appear probably round. The capsomer arrangement is clearly visible.

Electron microscopic preparation and references: Reference for electron microscopic methods: Banttari and Zeyen (1969).

Physicochemical and Physical Properties

There are 3 sedimenting component(s) found in purified preparations. The sedimentation coefficient is of the fastest 119 S20w. A260/A280 ratio is 1.63. The thermal inactivation point (TIP) is at 60-70°C. The longevity in vitro (LIV) is 16-32 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, single-stranded RNA is recovered. The complete genome is 6740 nucleotides long, is sequenced and complete sequence is about 6740 nucleotides long. The 3'-terminus has a subgenomic promoter, a conserved region known as "tymobox". Reference to nucleotide sequence Pring et al. (1973).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Translation: The genome replicates in in phloem cells.

Antigenicity

The virus is serologically related to Bermuda grass etched line viruses. The virus does not show serological relationships to Maize rayado fino virus.

Diagnostics and Reference Collections

The best tests for diagnosis are transmission to flax, barley and oats using the aster leafhopper. Crinkle in flax, leaf enations, serology, blue colour and dwarfing in leaves.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include stunting; include stunting of the internodes; include deformation of internodes. Symptoms in leaves include development of patterns or markings that are visible in the leaf margin and venation. Intercostal regions show malformation and change in color. Leaf veins are changed in color. Leaves are turning blue. Symptoms are deep; leaves with striations. Symptoms stunting, enations, deep blue colour in Avena sp.

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 Cicadellidae; Macrosteles fascifrons. Virus is not transmitted by Macrosiphum avenae. Virus is transmitted in a persistent manner; retained when the vector moults; replicates in the vector.

Chrysanthemum morifolium, Stellaria media — enations.

Linum grandiflorum, L. usitatissimum — enations, less tillering, dimples on leaves, stunting.

Spinacia oleracea — wrinkling and cupping of leaves.

Thlaspi arvense — see Westdal (1968). Diagnostic host: insusceptible host species Amaranthus retroflexus, Brassica campestris, Callistephus chinensis, Cucumis sativus, Zinnia elegans.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Avena sativa, Hordeum vulgare, Linum usitatissimum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Avena sativa (W), Hordeum vulgare (W), Linum usitatissimum (W).

References to host data: Westdal (1968).

Histopathology: Virus can be best detected in leaves, roots, meristems 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. Cytoplasmic inclusions are crystals, membranous bodies, and viroplasma. Inclusions contain mature virions. Other cellular changes include see Banttari and Zeyen (1971, Zeyen and Banttari (1972).

Geographical Distribution

The virus occurs in Canada, Finland, Sweden, and the United States of America.

Ecology, Epidemiology and Control

Studies reported by Banttari and Zeyen (1976, Long et al. (1975, Timian (1985, Westdal (1968).
