Data collated by J.A. Tomlinson, 1982. Revised 1984.

Nomenclature

Synonyms

lactuca virus 1.

Acronym

LMV

Strains

three pathotypes of the virus are recognised.

ICTV decimal code

57.0.1.0.038

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Lactuca spp., Senecio vulgaris, Sonchus spp. - necrotic or chlorotic local lesions and streaking, then mosaic, vein yellowing, leaf malformation.
• Cicer arietinum - leaf chlorosis.
• Pisum sativum - chlorotic mottling.

Transmission

Transmitted by a vector; an insect; Aphis gossypii, Macrosiphum euphorbiae, M. gei, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by seed (3-10%); transmitted by pollen to the seed.

Geographical distribution

Probably distributed worldwide (wherever Lactuca sativa is grown).

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Gomphrena globosa - necrotic local lesions; not systemic.
• Chenopodium amaranticolor, C. quinoa - necrotic local lesions; then systemic mosaic, rugosity.
• Carthamus tinctorius, Nicotiana benthamiana - systemic mosaic.

Maintenance and propagation hosts

Chenopodium quinoa, Lactuca sativa.
