Nomenclature

Synonyms

eggplant severe mosaic virus.

Acronym

ESMV

Strains

eggplant and tomato strains.

ICTV decimal code

57.0.1.T.035

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Lycopersicon esculentum - conspicuous leaf mosaic.
• Solanum melongena - severe mottling, blistering and distortion of leaves, and abnormal serration of leaf margins (but cv. New York is resistant to infection).

Transmission

Transmitted by a vector; an insect; Aphis craccivora, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in Nigeria.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Capsicum annuum, Datura metel, Nicotiana megalosiphon, Physalis floridana - systemic vein-clearing and/or vein-banding.
• Datura stramonium, Lycopersicon esculentum, Nicotiana clevelandii, Nicotiana benthamiana - systemic leaf mottling.
• Nicotiana sylvestris, N. tabacum - diffuse local lesions; no systemic infection.
• Nicotiana occidentalis - local chlorotic spots and rings; systemic leaf mottling.

Diagnostically insusceptible host species

Arachis hypogaea, Cajanus cajan, Vigna unguiculata, Vigna unguiculata ssp. cylindrica.

Maintenance and propagation hosts

Physical and biochemical properties

Properties of particles in sap

TIP: 55-65 °C. LIV: 7-9 days (eggplant strain). DEP: log₁₀ minus 5.

Cytopathology

Virions found in leaves; in cytoplasm. Inclusions present in infected cells; are pinwheels; they do not contain virions. Other cellular changes: enlarged, unusually vesiculated and disrupted mitochondria.
