Nomenclature

Synonyms

cucumber yellows virus (Yamashita et al., 1979), muskmelon yellows virus (Liu and Duffus, 1990; Lot et al., 1982).

Acronym

BPYV.

ICTV decimal code

17.0.1.T.3.01

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Beta vulgaris, Lactuca sativa, Cichorium endiva - yellowing, thickening, brittleness of leaves.
• Capsella bursa-pastoris, Cucumis sativus - yellowing, thickening, brittleness and down-curling of leaf margins.
• Taraxacum officinale - interveinal reddening and chlorosis.
• Conium maculatum - symptoms not described.

Transmission

Transmitted by a vector; an insect; Trialeurodes vaporariorum; Aleyrodidae. Transmitted in a semi-persistent manner. Virus does not multiply in the vector; not transmitted congenitally to the progeny of the vector; not transmitted by mechanical inoculation; not transmitted by contact between plants; not transmitted by seed.

Geographical distribution

Spreads in Australia (Tasmania), France, Japan, the Netherlands, the USA (California).

Experimental host range

Many (>9) families susceptible. Experimentally infected plants mostly show yellowing, reddening, curling.

Diagnostically susceptible host species and symptoms

• Beta vulgaris, Capsella bursa-pastoris, Lactuca sativa - yellowing, thickening, brittleness of leaves.
• Taraxacum officinale, Chenopodium capitatum - interveinal reddening and chlorosis.
• Linum usitatissimum, Nicotiana glutinosa, Cucumis melo - interveinal yellowing.

Diagnostically insusceptible host species

Datura stramonium, Lycopersicon esculentum, Physalis floridana, Tetragonia tetragonioides.

Physical and biochemical properties

NCBI sequence data (Entrez search)

Replication

Replication does not depend on a helper virus.

Taxonomy and relationships

Possible Closterovirus

Additional comments on relationships

Beet pseudo-yellows virus seems similar to cucumber yellows virus, from Japan and also transmitted by Trialeurodes vaporariorum, but has a host range restricted to cucurbits and has flexuous virions of c. 1000 nm long (Yamashita et al., 1979).
