Classification

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

ICTVdB Virus Code: 00.057.0.01.079. Virus accession number: 57001079. Obsolete virus code: 57.0.1.T.044; superceded accession number: 5701t044.

Name, Synonyms and Lineage

ICTV approved acronym: HyaMV. Virus is an ICTV approved species 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 740 nm. Axial canal is indistinct. Basic helix is obscure.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Phillips: extract from infected hyacinth leaves and flower stems by blending in 0.4 M Na citrate + 0.2 M urea + 10 mM DIECA + 0.2% (w/v) hemicellulase + 0.1% (v/v) mercapto-acetic acid (pH 6.9) (1 g : 4 ml). Incubate at 37°C for 1 hour. Add Triton X-100 (2% v/v of extractant) and stir for 30 minutes. Leave at 2°C overnight. Filter through cheesecloth and centrifuge (20 minutes at 12,000 g; 75 minutes at 65,000 g). Resuspend pellets in 0.2 M Na-citrate + 0.1 M urea + 0.1% (v/v) mercapto-acetic acid (pH 6.6, 1 ml/1 g of plant material). Leave at 2°C overnight. Give a second cycle of differential centrifugation and resuspend pellets in a 33 mM phosphate buffer (pH 7.3).

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 ornithogalum mosaic, scilla mosaic, freesia mosaic and iris severe mosaic viruses. The virus does not show serological relationships to bean yellow mosaic, hippeastrum mosaic, iris mild mosaic, narcissus yellow stripe, onion yellow dwarf, potato Y, tulip breaking and turnip mosaic viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

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; not transmitted by seeds; not transmitted by pollen.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Myzus persicae, Macrosiphum solanifolii. 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 Hyacinthaceae. The following species were susceptible to experimental virus infection: Hyacinthus orientalis.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Chenopodiaceae, or Leguminosae-Papilionoideae, Liliaceae, Solanaceae, Tetragoniaceae. Species inoculated with virus that do not show signs of susceptibility: Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Gomphrena globosa, Lilium formosanum, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana tabacum, Petunia x hybrida, Phaseolus vulgaris, Tetragonia tetragonioides, Trifolium incarnatum, Vicia faba.

Diagnostic Hosts

Diagnostic host: insusceptible host species Chenopodium quinoa, Lilium formosanum, Nicotiana clevelandii, Phaseolus vulgaris, Tetragonia tetragonioides.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Hyacinthus orientalis.

Geographical Distribution

The virus occurs in Australia, Bulgaria, the Netherlands, the United Kingdom, and the United States of America.
