Nomenclature

ICTV decimal code

57.0.1.T.D.03

Host range and symptoms

Natural host range and symptoms

Symptoms none.
• Apium graveolens var. dulce, A. graveolens var. rapaceum - symptomless.

Transmission

Transmitted by means not involving a vector. Not transmitted by Acyrthosiphon pisum, Aphis fabae, Cavariella aegopodii, Macrosiphum euphorbiae, Myzus persicae, Aulacorthum circumflexum. Virus transmitted by mechanical inoculation; transmitted by grafting; transmitted by seed.

Ecology and control

Studies reported by Verhoyen et al. (1976); Bos et al. (1978). The virus was detected in seedlings of commercial cultivars of celery and celeriac. The virus seemed to reduce the yield and the use of virus-free mother plants for seed production was advised. The availability of antiserum facilitates this control.

Geographical distribution

Spreads in Belgium, Italy, and the Netherlands.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show no symptoms. Some Chenopodium and Amaranthus species and Atriplex hortensis give local lesions and generally systemic rings, flecks, deformations and dwarfing.

Diagnostically susceptible host species and symptoms

• Apium graveolens var. dulce, A. graveolens var. rapaceum - no visible symptoms.
• Anthriscus cerefolium, Coriandrum sativum - symptomless.
• Chenopodium quinoa - local lesions, chlorotic flecks and rings with slight leaf deformation.
• Chenopodium amaranticolor - local lesions; less distinct systemic symptoms.
• Amaranthus hypochondriacus - necrotic local lesions; sometimes severe systemic symptoms.

Diagnostically insusceptible host species

Anethum graveolens, Daucus carota, Pastinaca sativa, Petroselinum crispum, Nicotiana rustica.

Maintenance and propagation hosts

Apium graveolens var. dulce (for maintaining the virus long term), Chenopodium quinoa (for maintaining and propagating the virus short term).

Assay hosts (Local lesions or Whole plants)

Sources of host-range data

Bos et al. (1978); Brandes and Luisoni (1966); Luisoni (1966); Verhoyen et al. (1976).

Physical and biochemical properties

Properties of particles in sap

TIP: 54 °C. LIV: 10 days. DEP: log₁₀ minus 4. Leaf sap contains few virions.

Purification method

Bos et al. (1978).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 860 nm. Axial canal obvious.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 161 S.

Cytopathology

Virions found in leaves; in cytoplasm. Inclusions absent from infected cells. Other cellular changes: bundles of virions in the cytoplasm, often near or parallel to the tonoplast (Verhoyen et al., 1976; Bos et al., 1978).

Taxonomy and relationships

Potyvirus: Potyviridae (possibly)

Best tests for diagnosis

ISEM and decoration is diagnostic. Susceptibility of C. quinoa is not as some strains of celery mosaic virus.
