Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Syringa vulgaris - chlorotic local lesions, which may coalesce, enlarge and produce indistinct line patterns.

Transmission

Not transmitted by Aphis gossypii, Macrosiphoniella sanborni, Myzus ligustri, M. persicae. Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by seed.

Geographical distribution

Found, but with no evidence of spread, in south east England.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Beta vulgaris, Chenopodium quinoa - irregular necrotic local lesions, then systemic leaf chlorosis.
• Chenopodium amaranticolor, C. capitatum, C. murale - few necrotic local lesions; not systemic.
• Nicotiana clevelandii, N. glutinosa, N. glutinosa × N. clevelandii, N. rustica - faint systemic leaf chlorosis.
• Phaseolus vulgaris - systemic chlorotic local lesions.

Physical and biochemical properties

Properties of particles in sap

TIP: 65 °C. LIV: 8-16 days (at 20ºC). DEP: log₁₀ minus 4. Leaf sap contains few virions.

Purification method

Brunt (1978).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 1536 nm; 12.5 nm wide. Axial canal obscure. Basic helix occasionally obvious, or obscure (usually); pitch of basic helix 3.69 nm.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 96 S. Density 1.302 g cm^-3 in CsCl. A₂₆₀/A₂₈₀ ratio 1.69.

Features of proteins

Virion protein(s) one; M_r 27000; coat protein.

Cytopathology

Virions found in leaves, mesophyll and the vascular parenchyma; in cytoplasm. Inclusions present in infected cells; are viroplasms; they contain virions. Other cellular changes: enlarged and sinuous thylakoids in chloroplasts near inclusions.

Taxonomy and relationships

Capillovirus

Virus(es) with serologically unrelated virions

Beet yellow stunt, beet yellows, carnation necrotic fleck and apple chlorotic leafspot viruses.
