Isolate Description

Location: Nigeria.

Host of Isolate and Habitat Details
Source of isolate: Solanum melongena.

Natural host and symptoms
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).

Reference to Isolation Report
Ladipo et al. (1988).

Classification

This is a description of a plant virus at the species level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 00.057.0.81.035. Virus accession number: 57081035. Obsolete virus code: 57.0.1.T.035; superceded accession number: 5701t035.

Name, Synonyms and Lineage

Synonym(s): eggplant severe mosaic virus. ICTV approved acronym: ESMV. Virus is a tentative member. Virus is of the genus 00.057.0.01. Potyvirus; family 00.057. Potyviridae .

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 55-65°C. The longevity in vitro (LIV) is 7-9 days (eggplant strain). Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to dioscorea green banding mosaic, eggplant green mosaic, groundnut eyespot, peanut stripe (mungbean isolate), pepper veinal mottle and telfairia mosaic viruses. The virus does not show serological relationships to amaranthus leaf mottle, bean common mosaic, bean yellow mosaic, beet mosaic, celery mosaic, Colombian datura, henbane mosaic, pea seed-borne mosaic, pepper mild mottle, pepper mottle, Peru tomato, potato A, potato Y, soybean mosaic, sugarcane mosaic, sweet potato feathery mottle, tobacco etch, turnip mosaic, watermelon mosaic 2, wild potato mosaic and zucchini yellow mosaic viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Aphis craccivora, Myzus persicae. Virus is transmitted in a non-persistent manner.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in few families. Susceptible host species are found in the Family Leguminosae-Papilionoideae, Solanaceae. The following species were susceptible to experimental virus infection: Capsicum annuum, Capsicum frutescens, Datura metel, Datura stramonium, Lycopersicon esculentum, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana debneyi, Nicotiana glutinosa, Nicotiana megalosiphon, Nicotiana occidentalis, Nicotiana rustica, Nicotiana sylvestris, Nicotiana tabacum, Physalis floridana, Physalis peruviana, Solanum melongena, Vigna unguiculata.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Leguminosae-Papilionoideae. Species inoculated with virus that do not show signs of susceptibility: Arachis hypogaea, Cajanus cajan, Vigna unguiculata, Vigna unguiculata ssp. cylindrica.

Diagnostic Hosts

Diagnostic 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.

Diagnostic host: insusceptible host species Arachis hypogaea, Cajanus cajan, Vigna unguiculata, Vigna unguiculata ssp. cylindrica.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Solanum melongena (eggplant strain), Nicotiana megalosiphon, N. occidentalis (tomato strain).

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Nicotiana occidentalis (W), Solanum melongena (W).

References to host data: Ladipo et al. (1988).

Histopathology: Virus can be best detected in leaves. Virions are found in the cytoplasm.

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Cytoplasmic inclusions are pinwheels. Inclusions do not contain mature virions. Other cellular changes include enlarged, unusually vesiculated and disrupted mitochondria.

Geographical Distribution

The virus occurs in Nigeria.

List of Strains and Isolates in the Species

Eggplant and tomato strains.
