Nomenclature

Acronym

CaLV

ICTV decimal code

14.0.T.1.007

Host range and symptoms

Natural host range and symptoms

• Cardamine lilacina ssp. B and C - latent.

Transmission

Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in Australia (southern New South Wales, but probably not in Tasmania).

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show local lesions vein-clearing.

Diagnostically susceptible host species and symptoms

• Chenopodium quinoa - large local lesions; not systemic.
• Sinapis alba cv. White Mustard - systemic vein clearing with leaves malformed.

Diagnostically insusceptible host species

Brassica campestris ssp. pekinensis.

Maintenance and propagation hosts

Cardamine lilacina spp. B and C.

Assay hosts (Local lesions or Whole plants)

Chenopodium quinoa (L); Sinapis alba (W).

Susceptible host species
