Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; 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 Cruciferae, Rosaceae. The following species were susceptible to experimental virus infection: Armoracia rusticana, Brassica campestris, Brassica campestris ssp. napus, Brassica campestris ssp. pekinensis, Brassica campestris ssp. rapa, Malus sylvestris, Matthiola incana.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Chenopodiaceae, Compositae, Cruciferae, or Cucurbitaceae, Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Beta vulgaris, Brassica juncea, Chenopodium amaranticolor, Chenopodium quinoa, Cucumis melo, Cucumis sativus, Datura stramonium, Lactuca sativa, Lycopersicon esculentum, Nicotiana bigelovii, Nicotiana glutinosa, Nicotiana tabacum, Phaseolus vulgaris, Pisum sativum, Vigna unguiculata, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Brassica campestris ssp. rapa — local chlorotic lesions; mild systemic chlorotic mottling and faint chlorotic banding of main veins.

Matthiola incana — mild chlorotic mottling of systemically infected leaves.

Diagnostic host: insusceptible host species Beta vulgaris, Chenopodium quinoa, Cucumis sativus, Nicotiana tabacum, Phaseolus vulgaris.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Brassica campestris cv. Just Right.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Brassica campestris cv. Just Right (W).

References to host data: Richins and Shepherd (1986).

Geographical Distribution

The virus occurs in Denmark.
