Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms stunting, enations, deep blue colour in Avena sp.
• Avena sativa - stunting, short stiffened leaves, bluish leaves, enations along leaf veins, sterility of florets.
• Hordeum vulgare, Chrysanthemum morifolium, Hordeum jubatum, Spinacia oleracea, Stellaria media, Thlaspi arvense - dwarfing and stiffening of leaves, enations.
• Linum grandiflorum, L. usitatissimum - stunting, prominent enations along leaf veins.

Transmission

Transmitted by a vector; an insect; Macrosteles fascifrons; Cicadellidae. Not transmitted by Macrosiphum avenae. Transmitted in a persistent manner. Virus retained when the vector moults; multiplies in the vector; not transmitted by mechanical inoculation; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Ecology and control

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

Geographical distribution

Spreads in Canada, Finland, Sweden, and the USA.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show stunting, enations along leaf veins, bluish color, sterility of florets.

Diagnostically susceptible host species and symptoms

• Avena sativa, Hordeum vulgare - enations, blue colour, stunting, sterility, excess tillering.
• 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).

Sources of host-range data

Westdal (1968).

Physical and biochemical properties

Properties of particles in sap

TIP: 60-70 °C. LIV: 16-32 days. DEP: log₁₀ minus 5.

Purification method

Banttari and Zeyen (1969).

Particle morphology

Virions isometric; not enveloped; 28-30 nm in diameter; probably rounded in profile; with a conspicuous capsomere arrangement.

Physical properties

Three sedimenting components in purified preparations; sedimentation coefficient of the fastest 119 S. A₂₆₀/A₂₈₀ ratio 1.63.

Biochemical properties

Genome consists of RNA; single-stranded; linear. Total genome size 6.74 kb. Genome unipartite; largest (or only) genome part 6.74 kb. Genomic nucleic acid isolated by Pring et al. (1973). Additional factor not required for infectivity.

Replication

Genome replicates in phloem cells. Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves, roots, meristems and phloem; in cytoplasm. Inclusions present in infected cells; are crystals in the cytoplasm, membranous bodies, and viroplasms; they contain virions. Other cellular changes: see Banttari and Zeyen (1971); Zeyen and Banttari (1972).

Taxonomy and relationships

Marafivirus

Virus(es) with serologically related virions

Bermuda grass etched line viruses.

Virus(es) with serologically unrelated virions

Maize rayado fino virus.

Best tests for diagnosis

Transmission to flax, barley and oats using the aster leafhopper. Crinkle in flax, leaf enations, serology, blue colour and dwarfing in leaves.
