Data collated by Sc.H. Kleinhempel, 1987.

Nomenclature

Synonyms

beet leaf crinkle virus, beta virus 3, Rübenkräusel-Virus, sugarbeet leafcurl rhabdovirus.

Acronym

BLCV

ICTV decimal code

62.U.P.0.002

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Beta vulgaris - vein deformation, leaves curved towards the apex.

Transmission

Transmitted by a vector; an insect; Heteroptera, Lygaeidae: Piesma quadratum. Transmitted in a persistent manner. Virus retained when the vector moults; multiplies in the vector; not transmitted congenitally to the progeny of the vector; not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants.

Ecology and control

Studies reported by Proeseler (1980).

Geographical distribution

Spreads in the Eurasian region and the Mediterranean region; the former Czechoslovakia, Germany, Poland, Turkey, and the former USSR.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show vein clearing, leaf curling, stunting.

Diagnostically susceptible host species and symptoms

• Beta vulgaris, Chenopodium quinoa, Spinacia oleracea, Tetragonia tetragonioides - vein clearing, leaf curling, stunting.

Maintenance and propagation hosts

Beta vulgaris.

Assay hosts (Local lesions or Whole plants)

Beta macrocarpa (W), Atriplex patula (W), Chenopodium murale (W), Spinacia tetranda (W).

Susceptible host species

• Atriplex patula
• Beta macrocarpa
• Beta vulgaris
• Chenopodium album
• Chenopodium amaranticolor
• Chenopodium capitatum
• Chenopodium foliosum
• Chenopodium murale
• Chenopodium quinoa
• Spinacia oleracea
• Spinacia tetranda
• Tetragonia tetragonioides

Families containing susceptible hosts

• Chenopodiaceae (11/11)
• Tetragoniaceae (1/1)

Sources of host-range data

Proeseler (1966); Schmutterer and Ehrhardt (1966).

Physical and biochemical properties

Properties of particles in sap

TIP: 54-58 °C. LIV: less than 1 days. DEP: log₁₀ minus 4-5.

Purification method

Eisbein and Proll (1978).

Particle morphology

Virions rhabdo- or bullet-shaped; enveloped; of 225-350 nm (longer in roots); 80 nm wide.

Physical properties

One sedimenting component in purified preparations.

Cytopathology

Virions found in leaves, roots mesophyll and vascular parenchyma; in cytoplasm, in the perinuclear space, and in cell vacuoles. Inclusions present in infected cells; are crystals in the cytoplasm; they contain virions.

Taxonomy and relationships

unassigned rhabdovirus
