Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.057.0.01.081. Virus accession number: 57001081. Obsolete virus code: 57.0.1.T.059; superceded accession number: 5701t059.

Name, Synonyms and Lineage

Synonym(s): Nerine virus. ICTV approved acronym: NV. Virus is an ICTV approved species. Virus is of the genus 00.057.0.01. Potyvirus in the 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 780 nm and a width of 12 nm. Axial canal is indistinct. Basic helix is obscure.

Electron microscopic preparation and references: Virus preparation contains few virions. ISEM best for finding virions in sap. Reference for electron microscopic methods: Phillips: Homogenise infected leaves in 0.25M phosphate: 0.1M ascorbic acid: 0.14M mercaptoacetic acid (3:9:1 vols/wt; pH7.0), then ether and finally carbon tetrachloride (1:1 vols). Stir for 15 minutes then two cycles differential centrifugation.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 65°C.

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 potato Y (SDI 5), henbane mosaic (SDI 8), clover yellow vein, (SDI 9) and alstroemeria mosaic (SDI 10) viruses. The virus does not show serological relationships to bean yellow mosaic (gladiolus and crocus strains), carnation vein mottle, freesia mosaic, hippeastrum mosaic, iris mild mosaic, narcissus degeneration, narcissus late season yellows, pea mosaic, pepper veinal mottle, tobacco severe etch, and watermelon mosaic viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).

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; not transmitted by contact between hosts.

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

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in several families. Susceptible host species are found in the Family Amaryllidaceae, Chenopodiaceae, Solanaceae, Tetragoniaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium capitatum, Chenopodium murale, Chenopodium quinoa, Hyoscyamus niger, Nerine bowdenii, Nerine sarniensis, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana glutinosa x N. clevelandii, Nicotiana megalosiphon, Nicotiana rustica, Nicotiana sylvestris, Nicotiana tabacum, Tetragonia tetragonioides.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Alstroemeriaceae, Amaranthaceae, or Compositae, Cruciferae, Cucurbitaceae, Iridaceae, or Leguminosae-Papilionoideae, Liliaceae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Alstroemeria caryophylla, Belamcanda chinensis, Brassica campestris ssp. pekinensis, Calendula officinalis, Cucumis sativus, Dahlia pinnata, Datura metel, Gomphrena globosa, Helianthus annuus, Lactuca sativa, Lilium formosanum, Lycopersicon esculentum, Phaseolus vulgaris, Solanum demissum, Solanum tuberosum, Trifolium incarnatum, Vicia faba, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Nicotiana clevelandii — systemic chlorotic vein-banding.

Chenopodium quinoa — chlorotic local lesions.

Chenopodium amaranticolor — small chlorotic local lesions.

Chenopodium murale — diffuse chlorotic local lesions.

Hyoscyamus niger — chlorotic local lesions.

Nicotiana benthamiana — chlorotic local lesions, then systemic chlorotic vein-banding.

Tetragonia tetragonioides — green chlorotic rings.

Diagnostic host: insusceptible host species Alstroemeria caryophylla, Phaseolus vulgaris, Solanum tuberosum, Belamcanda chinensis, Trifolium incarnatum.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Nicotiana clevelandii, Nicotiana benthamiana.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Nicotiana clevelandii (W), Nicotiana benthamiana (W), Chenopodium quinoa (L), Chenopodium amaranticolor (L), Hyoscyamus niger (L).

Histopathology: Virus can be best detected in all parts of the host plant.

Geographical Distribution

The virus occurs in the Netherlands and the United Kingdom.
