Nomenclature

Acronym

AlSV

ICTV decimal code

57.0.1.T.001

Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms streaking and stunting.
• Alstroemeria - streaking, stunting and mosaic of leaves.

Transmission

Transmitted by a vector; an insect; Macrosiphum euphorbiae; Aphididae. Virus transmitted by mechanical inoculation; not transmitted by contact between plants.

Geographical distribution

Found, but with no evidence of spread, in Netherlands, UK and USA.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show chlorotic streaking.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor, Hyoscyamus niger, Tetragonia tetragonioides - local chlorotic lesions, not systemic.
• Nicotiana benthamiana, N. clevelandii, N. hesperis 67A, N. occidentalis P1 - local chlorotic lesions, systemic chlorosis.
• Nicotiana occidentalis - systemic chlorosis. Nicotiana occidentalis Japan - systemic chlorotic streaks parallel to midrib.

Diagnostically insusceptible host species

Nicotiana glutinosa, Chenopodium quinoa.

Maintenance and propagation hosts

Nicotiana occidentalis Japan.

Assay hosts (Local lesions or Whole plants)

Nicotiana occidentalis Japan (W).

Susceptible host species

• Alstroemeria
• Chenopodium amaranticolor
• Hyoscyamus niger
• Nicotiana benthamiana
• Nicotiana clevelandii

• Nicotiana glutinosa

Families containing susceptible hosts

• Alstroemeriaceae (1/1)

Physical properties

One sedimenting component in purified preparations. A₂₆₀/A₂₈₀ ratio 1.34.

Biochemical properties

Genome unipartite.

Features of proteins

Virion protein(s) one; M_r 30000; coat protein.

Cytopathology

Virions found in cytoplasm. Inclusions present in infected cells; are pinwheels (and laminated aggregates).

Taxonomy and relationships

Possible unassigned potyvirus

Virus(es) with serologically related virions

Alstroemeria mosaic virus.
