Nomenclature

Acronym

WVMV

ICTV decimal code

57.0.1.0.074

Host range and symptoms

Natural host range and symptoms

Symptoms persist and vary seasonally. Symptoms irregular vein mosaic.
• Wisteria floribunda, W. sinensis - yellowing, vein clearing, flecking, mottling or mosaic, some malformation.

Transmission

Transmitted by a vector; an insect; Aphis craccivora, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by seed.

Geographical distribution

Spreads in the former Czechoslovakia, Italy, and the Netherlands (and probably several other countries).

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show chlorotic, sometimes necrotic local lesions, sometimes followed by chlorotic mottling to mosaic.

Diagnostically susceptible host species and symptoms

• Atriplex hortensis, Chenopodium amaranticolor - chlorotic local lesions.
• Chenopodium quinoa - chlorotic to yellow local lesions, becoming green.
• Cicer arietinum - chlorotic local lesions, then necrotic mosaic, stunting and withering.
• Lupinus albus - chlorotic, later necrotic, local lesions followed by bright mosaic.
• Nicotiana clevelandii - systemic chlorotic spots and rings, sometimes faint chlorotic local lesions.
• N. tabacum cv. White Burley - chlorotic local lesions.
• Phaseolus vulgaris - chlorotic, later necrotic local lesions then, usually, systemic mottling, flecking or stippling.
• Pisum sativum - interveinal chlorotic spotting or mottling.
• Vicia faba - chlorotic ring-like local lesions; diffuse chlorotic systemic spots.

Diagnostically insusceptible host species

Beta vulgaris, Cucumis sativus cv. Gele Tros, Datura stramonium, Nicotiana glutinosa, Vigna unguiculata.

Maintenance and propagation hosts

Pisum sativum, Nicotiana clevelandii.

Sources of host-range data

Bos (1970); Conti and Lovisolo (1970).

Physical and biochemical properties

Properties of particles in sap

TIP: 55 °C, or 60 °C. LIV: 2 days, or 12 days. DEP: log₁₀ minus 3, or 5. Leaf sap contains few virions.

Purification method

Bos (1970).

Particle morphology

Virions filamentous; usually flexuous; with a clear modal length; of 750-775 nm. Axial canal obscure. Basic helix obscure.

Cytopathology

Virions found in leaves. Inclusions present in infected cells; are pinwheels and unusual in shape; granular cytoplasmic inclusions; they contain virions.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Bean yellow mosaic, bean common mosaic and clover yellow vein viruses.

Best tests for diagnosis

The virions of WVMV are only distantly related serologically to those of bean yellow mosaic virus and clover yellow vein virus when using polyclonal antisera. WVMV differs from bean yellow mosaic virus in not infecting red clover and cowpea and in infecting Chenopodium quinoa systemically. It differs from clover yellow vein virus in not infecting cucumber (in which clover yellow vein virus causes local lesions) and in not infecting white clover.
