Data collated by A.A. Brunt, 1992.

Nomenclature

ICTV decimal code

57.0.1.T.D.10

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Petroselinum crispum - green mottling of leaves; the virus and a strain of chicory yellow mottle nepovirus in complex together cause parsley bushy stunt disease.

Transmission

Transmitted by a vector; an insect; Acyrthosiphon pisum, Aphis spiraecola, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by seed.

Geographical distribution

Spreads in Italy.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Apium graveolens cv. Doré Barbier - conspicuous chlorosis in systemically infected leaves (infection is symptomless in some other cultivars).
• Ammi majus - transient systemic leaf chlorosis.
• Chenopodium amaranticolor, C. quinoa - local lesions, general chlorosis and/or vein yellowing.
• Petroselinum crispum - mosaic, reduced laminae and distortion of systemicallly infected leaves.
• Pimpinella anisum - symptomless systemic infection.

Diagnostically insusceptible host species

Beta vulgaris.

Maintenance and propagation hosts

Petroselinum crispum, Apium graveolens cv. Doré Barbier.

Assay hosts (Local lesions or Whole plants)

Petroselinum crispum (W), Apium graveolens (W).

Susceptible host species

• Ammi majus
• Apium graveolens
• Chenopodium amaranticolor
• Chenopodium quinoa
• Petroselinum crispum
• Pimpinella anisum

Insusceptible host species

• Beta vulgaris

Families containing susceptible hosts

• Chenopodiaceae (2/3)
• Umbelliferae (4/4)

Families containing insusceptible hosts

Physical and biochemical properties

Properties of particles in sap

TIP: 53 °C. LIV: 6 days. DEP: log₁₀ minus 3. Leaf sap contains few virions.

Purification method

Angelis and Quacquarelli (1974).

Particle morphology

Virions filamentous; usually flexuous; with a clear modal length; of 758 nm; 12-15 nm wide. Axial canal obscure. Basic helix obscure.

Taxonomy and relationships

unassigned potyvirus

Virus(es) with serologically unrelated virions

Celery mosaic potyvirus.
