Pelargonium leaf
curl tombusvirus
Index
Data collated by A.A. Brunt, 1995.
Nomenclature
Synonyms
geranium crinkle virus (Pethybridge and Smith,
1952), tomato bushy stunt virus - pelargonium strain (Martelli et al.,
1971).
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Pelargonium zonale; from Germany; by Pape (1927).
Natural host range and symptoms
- Pelargonium
zonale - pale chlorotic spots, which later become stellate and necrotic,
leaf crinkling and plant degeneration.
Transmission
Virus transmitted by mechanical inoculation;
transmitted by grafting; not transmitted by seed.
Ecology and
control
Studies reported by Hollings (1962); Hollings and Stone (1965).
Geographical distribution
Spreads in the Eurasian region, the
Mediterranean region, and the North American region.
Diagnostically susceptible host species and symptoms
- Chenopodium amaranticolor, Datura stramonium, Phaseolus
vulgaris - chlorotic and/or necrotic local lesions; systemic chlorosis
and necrosis.
- Nicotiana clevelandii - local chlorotic lesions and
rings; severe systemic chlorotic and semi-necrotic spots and rings.
Maintenance and propagation hosts
Datura stramonium,
Nicotiana clevelandii.
Assay hosts (Local
lesions or Whole plants)
Chenopodium
amaranticolor (L), Datura stramonium (L), Phaseolus vulgaris
(L).
Susceptible host species
Families containing susceptible hosts
Physical and
biochemical properties
Properties of particles in sap
TIP: 90
°C. LIV: 21 days. DEP: log10 minus 4.
Purification method
Gallitelli
et al. (1985).
Particle morphology
Virions isometric; not enveloped; 28
nm in diameter.
Physical properties
One sedimenting component in purified
preparations; sedimentation coefficient 136 S. Density 1.34 g cm-3
in CsCl.
Biochemical properties
Virions contain 17 % nucleic acid;
83 % protein; 0 % lipid.
Genome consists of RNA; single-stranded. Total genome size 4.7 kb. Genome
unipartite; largest (or only) genome part 4.7 kb.
Features of proteins
Virion protein(s) one;
Mr 41000; coat protein.
Cytopathology
Virions found in cytoplasm, in nuclei, in
nucleoli, in the perinuclear space, in chloroplasts, and in cell vacuoles.
Inclusions present in infected cells; are crystals in the cytoplasm; they do not
contain virions. Other cellular changes: nucleoli enlarged, chromatin depleted.
Taxonomy and
relationships
Virus(es) with serologically related virions
Carnation Italian ringspot and tomato bushy stunt viruses.
Additional comments on relationships
The genome of the virus has 24% sequence identity with that of tomato
bushy stunt virus.
