Host of Isolate and Habitat Details
Source of isolate: Capsicum annuum.

Natural host and symptoms
Capsicum annuum, C. frutescens — dark green mottling adjacent to main leaf veins, reduction in leaf area and distortion; plants stunted (severity dependent upon cultivar and duration of infection).

Capsicum ssp. — veinal mottle, malformation.

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: 00.057.0.01.016. Virus accession number: 57001016. Obsolete virus code: 57.0.1.0.016; superceded accession number: 57010016.
NCBI Taxon Identifier NCBI Taxonomy ID: 52280.

Name, Synonyms and Lineage

ICTV approved acronym: ChiVMV. Virus is an ICTV approved species 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, flexuous with a clear modal length with a length of 750 nm and a width of 12 nm.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 60°C. The longevity in vitro (LIV) is 7 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 4.

Nucleic Acid

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

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to potato Y, tobacco etch, pepper veinal mottle and pepper mottle (S.K. Green, personal communication).

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

General Symptoms in Plants Symptoms veinal mottle, malformation.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation; transmitted by grafting; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Aphis craccivora, A gossypii, A spiraecola, Myzus persicae, Toxoptera citricidus, Hysteroneura setarieae, Rhopalosiphum maidis. 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 Solanaceae. The following species were susceptible to experimental virus infection: Capsicum annuum, Capsicum frutescens, Hyoscyamus niger, Nicandra physalodes, Nicotiana megalosiphon, Nicotiana tabacum, Physalis floridana.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Apocynaceae, or Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, Gramineae, or Leguminosae-Caesalpinioideae, Leguminosae-Papilionoideae, Passifloraceae, Solanaceae, Tetragoniaceae. Species inoculated with virus that do not show signs of susceptibility: Ageratum conyzoides, Arachis hypogaea, Brassica juncea, Brassica oleracea var. capitata, Cassia occidentalis, Catharanthus roseus, Chenopodium amaranticolor, Chenopodium capitatum, Chenopodium quinoa, Cucumis sativus, Datura stramonium, Gomphrena globosa, Luffa acutangula, Lycopersicon esculentum, Nicotiana glutinosa, Nicotiana rustica, Passiflora edulis, Phaseolus vulgaris, Solanum melongena, Solanum nigrum, Tetragonia tetragonioides, Vigna unguiculata, Vigna unguiculata ssp. sesquipedalis , Zea mays, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Capsicum annuum — systemic vein clearing, followed by leaf mottling.

Diagnostic host: insusceptible host species Chenopodium quinoa, Datura stramonium, Gomphrena globosa, Cucumis sativus.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Capsicum annuum, Nicandra physalodes, Nicotiana megalosiphon, Physalis floridana, Nicotiana tabacum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Capsicum annuum (W).

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Cytoplasmic inclusions are pinwheels.

Geographical Distribution

The virus occurs in Korea (North), Korea (South), Malaysia, the Philippines, Taiwan, and Thailand.
