Nomenclature

Acronym

ALiMV

ICTV decimal code

57.0.1.T.002

Host range and symptoms

Natural host range and symptoms

Eucharis grandiflora - leaf mosaic.

Transmission

Transmitted by a vector; an insect; Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus lost by the vector when it moults; transmitted by mechanical inoculation.

Geographical distribution

Geographical distribution probably restricted. Spreads in the Eastern Asian region; Japan.

Experimental host range

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

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor, C. quinoa - necrotic local lesions, not systemic.
• Nicotiana benthamiana - systemic leaf mosaic.

Maintenance and propagation hosts

Nicotiana benthamiana.

Assay hosts (Local lesions or Whole plants)

Chenopodium amaranticolor (L), C. quinoa (L).

Susceptible host species

• Chenopodium amaranticolor
• Chenopodium quinoa
• Eucharis grandiflora
• Nicotiana benthamiana

Families containing susceptible hosts

• Amaryllidaceae (1/1)
• Chenopodiaceae (2/2)
• Solanaceae (1/1)

Purification method

Terami et al. (1993).

Physical and biochemical properties

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 760 nm.

Physical properties

A₂₆₀/A₂₈₀ ratio 1.32.
