Isolate Description

Location: New York; the United States of America.

Host of Isolate and Habitat Details
Source of isolate: Alstroemeria sp.

Natural host and symptoms
Alstroemeria — streaking, stunting and mosaic of leaves.

Reference to Isolation Report
Wong et al. (1992).

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: 00.057.0.81.001. Virus accession number: 57081001. Obsolete virus code: 57.0.1.T.001; superceded accession number: 5701t001.

Name, Synonyms and Lineage

ICTV approved acronym: AlStV. Acronym(s): AlSV. 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.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Wong et al. (1992).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. A260/A280 ratio is 1.34.

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. Virions consist of 1 structural protein(s).

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to alstroemeria mosaic virus.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

General Symptoms in Plants Symptoms streaking and stunting.

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; Macrosiphum euphorbiae.

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 Alstroemeriaceae, Chenopodiaceae, Solanaceae, Tetragoniaceae. The following species were susceptible to experimental virus infection: Alstroemeria, Chenopodium amaranticolor, Hyoscyamus niger, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana hesperis (cv. 67A), Nicotiana occidentalis, Tetragonia tetragonioides.

Host:
Experimentally infected hosts mainly show symptoms of chlorotic streaking.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Chenopodiaceae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Chenopodium quinoa, Nicotiana glutinosa.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium amaranticolor, Hyoscyamus niger, Tetragonia tetragonioides — local chlorotic lesions, not systemic.

Nicotiana benthamiana, N. clevelandii, N. hesperis 67A, N. occidentalis P1 — local chlorotic lesions, systemic chlorosis.

Nicotiana occidentalis — systemic chlorosis. Nicotiana occidentalis Japan — systemic chlorotic streaks parallel to midrib.

Diagnostic host: insusceptible host species Nicotiana glutinosa, Chenopodium quinoa.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Nicotiana occidentalis Japan.

Assay Hosts

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

Histopathology: 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 (and laminated aggregates).

Geographical Distribution

The virus is found, but with no evidence of proliferation, in Netherlands, UK and USA.
