Nomenclature

Acronym

PeSMV

Strains

PSMV/type, PSMV₂₀, PSMV₁₂₇ and PSMV₁₅₁.

ICTV decimal code

57.0.1.0.051

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Capsicum annuum - necrotic spots and streaks in leaves and stems, leaf abscission, then chlorotic leaves. Fruit yield greatly decreased.

Transmission

Transmitted by a vector; an insect; Aphis craccivora, Macrosiphum euphorbiae and, except for type strain, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by grafting.

Ecology and control

Studies reported by Feldman and Gracia (1977).

Geographical distribution

Spreads in Argentina.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor, C. quinoa - local lesions; not systemic.
• Nicandra physalodes, Nicotiana debneyi, N. rustica, N. tabacum - local lesions, followed by systemic vein-clearing mosaic and/or chlorotic rings.
• Capsicum annuum, Nicotiana clevelandii, N. glutinosa, N. sylvestris - systemic leaf mottling and malformation.

Diagnostically insusceptible host species

Datura stramonium, Solanum tuberosum, Gomphrena globosa, Cucumis sativus, Phaseolus vulgaris.

Maintenance and propagation hosts

Nicotiana tabacum, N. sylvestris.

Sources of host-range data

Feldman and Gracia (1977).

Physical and biochemical properties

Properties of particles in sap

TIP: 85-90 °C. LIV: 32-64 days. DEP: log₁₀ minus 6-7 (values for type strain, but some strains less stable). Leaf sap contains few virions.

Purification method

Feldman and Gracia (1977).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 761 nm; 13 nm wide. Axial canal obscure. Basic helix obscure.

NCBI sequence data (Entrez search)

Sequence database accession code(s)

Cytopathology

Inclusions present in infected cells; are pinwheels; they do not contain virions.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Tobacco etch and potato Y viruses, but very distantly.

Virus(es) with serologically unrelated virions

Pepper mottle, pepper veinal mottle and turnip mosaic viruses.
