Caper latent
carlavirus
Index
Data collated by D. Gallitelli, 1991.
Nomenclature
Synonyms
caper vein banding virus.
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Capparis spinosa; from Apulia, southern Italy; by Gallitelli and Di
Franco (1987).
Natural host range and symptoms
Symptoms persist.
Symptoms vein yellowing.
- Capparis spinosa - vein yellowing in plants also infected
with caper vein yellowing rhabdovirus (Di Franco and Gallitelli, 1985).
Transmission
Virus transmitted by mechanical inoculation;
transmitted by grafting.
Geographical distribution
Spreads in
Italy (Apulia).
Experimental host range
Several (3-9) families
susceptible. Experimentally infected plants mostly show chlorotic or necrotic
local lesions, systemic mosaic and leaf malformation.
Diagnostically susceptible host species and symptoms
- Chenopodium amaranticolor - pinpoint local lesions.
- C.
quinoa, Nicotiana glutinosa - chlorotic local lesions.
- Capparis
spinosa var. rupestris - latent.
- Vigna radiata - red
local lesions.
- Phaseolus vulgaris - necrotic local lesions.
- Petunia × hybrida - chlorotic ringspots.
- Nicotiana
clevelandii, N. megalosiphon, N. benthamiana - systemic mosaic.
Diagnostically insusceptible host species
Nicotiana
tabacum cvs Samsun, White Burley, Gomphrena globosa, Celosia
cristata.
Maintenance and propagation hosts
Nicotiana benthamiana, N. clevelandii.
Assay hosts (Local lesions or Whole plants)
Chenopodium amaranticolor (L), C. quinoa (L), Phaseolus
vulgaris (L), Nicotiana megalosiphon (W), N. benthamiana (W).
Susceptible host species

Physical and
biochemical properties
Properties of particles in sap
Leaf sap
contains many virions.
Purification method
Sap-clarification with Triton X-100, differential centrifugation, centrifugation
through a 30% sucrose or 49% CsCl.
Particle morphology
Virions filamentous; not enveloped;
usually flexuous; of 662 nm. Axial canal obscure.
Physical properties
One sedimenting component in purified
preparations; sedimentation coefficient 168 S. Density 1.31 g cm-3
in CsCl.
Biochemical properties
Genome consists of RNA;
single-stranded; linear. Total genome size 8 kb. Genome unipartite; largest
(or only) genome part 8 kb. Genomic nucleic acid isolated by Gallitelli: phenol
SDS.
Features of the genome
Non-genomic nucleic acid
not found in the virions.
Features of proteins
Virion protein(s) one;
Mr 35000; coat protein. Method of preparation: Laemmli (1970).
Replication
Replication does not depend on a helper
virus.
Cytopathology
Virions found in leaves and mesophyll; in
cytoplasm. Inclusions present in infected cells; are membranous bodies; they
contain virions.
Taxonomy and
relationships
Virus(es) with serologically related virions
Virus(es) with serologically unrelated
virions
Carnation latent, poplar mosaic, potato
M, potato S, shallot latent, chrysanthemum B and pea streak viruses.
Best tests for diagnosis
Inoculation onto Capparis spinosa.
