Isolate Description

Location: the United Kingdom.

Host of Isolate and Habitat Details
Source of isolate: Apium graveolens.

Natural host and symptoms
Apium graveolens — yellow flecking and vein banding, leaves malformed.

Reference to Isolation Report
Hollings (1964).

Classification

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

ICTVdB Virus Code: 00.065.0.01.003.00.002. Virus accession number: 65201003. Obsolete virus code: 00.079.0.70.013.; 79.0.P.DE.13; accession number: 79070013; 790pde13.

Name, Synonyms and Lineage

The taxon is not listed in the current ICTV Report.

Virus is unclassified. Virus is not assigned to a genus; not assigned to a family.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 45°C. The longevity in vitro (LIV) is 2 days (at 18°C). Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 2.

Proteins

The viral genome encodes structural proteins.

Lipids

Lipids are not reported.

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 mechanical inoculation; transmitted by grafting; not transmitted by seeds.

Vector Transmission: Virus is not transmitted by Myzus persicae.

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 Umbelliferae. The following species were susceptible to experimental virus infection: Apium graveolens, Apium repens, Daucus carota, Petroselinum crispum.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Chenopodiaceae, Cucurbitaceae, or Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Chenopodium amaranticolor, Cucumis sativus, Nicotiana tabacum, Petunia x hybrida, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Apium graveolens — yellow vein-netting vein-banding, necrotic spotting and malformation.

Petroselinum crispum — green systemic spotting then chlorotic or necrotic spots and rings.

Daucus carota, Apium repens — transient spots or systemic yellow-netting.

Diagnostic host: insusceptible host species Chenopodium amaranticolor, Cucumis sativus, Nicotiana tabacum, Petunia x hybrida, Vigna unguiculata.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Apium graveolens, Petroselinum crispum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Apium graveolens (W).

Geographical Distribution

The virus occurs in the United Kingdom.
