Tomato pseudo
curly top (?) hybrigeminivirus
Index
Data collated by A.A. Brunt, 1991.
Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Lycopersicon esculentum; from the U.S.A.; by Giddings et al.
(1951).
Natural host range and symptoms
- Lycopersicon
esculentum - chlorosis (especially at leaf edges), vein-clearing, leaf
curling and cupping and shoot proliferation. Plants often severely stunted and
set few fruit.
- Ambrosia sp., Solanum nigrum - vein-clearing
and leaf rolling.
Transmission
Transmitted by a vector; an insect;
Micrutalis malleifera; Membracidae. Not transmitted by Acutalis
sp., Micrutalis clava, Spissistilus festinus. Transmitted in a
semi-persistent manner. Virus retained when the vector moults; not
transmitted by mechanical inoculation; not transmitted by seed.
Ecology and control
Studies reported by Tsai and Brown
(1991).
Geographical distribution
Spreads in the USA
(Florida).
Experimental host range
Several (3-9) families
susceptible.
Diagnostically susceptible host species and
symptoms
- Ambrosia sp., Datura stramonium, Lactuca
sativa, Lycopersicon esculentum, Nicotiana glutinosa, N. × edwardsonii,
Solanum melongena, Solanum nigrum - systemic vein-clearing, chlorosis,
leaf rolling or cupping and plant stunting.
Diagnostically
insusceptible host species
Beta vulgaris, Capsicum annuum, Cucumis
sativus, Nicotiana tabacum, Solanum melongena.
Maintenance and
propagation hosts
Lycopersicon esculentum, Nicotiana ×
edwardsonii, Solanum nigrum.
Assay hosts (Local lesions or Whole plants)
Lycopersicon esculentum (W), Solanum nigrum (W).
Susceptible host species

Physical and biochemical properties
Particle morphology
Virions geminate; not enveloped.
Biochemical properties
Genome consists of DNA;
single-stranded; circular.
Cytopathology
Virions found in leaves; in nuclei.
Inclusions present in infected cells; are viroplasms and unusual in shape;
fibrillar rings in nuclei; they contain virions.
Taxonomy and
relationships
Virus(es) with serologically related virions
Beet curly top hybrigeminivirus.
Additional comments on relationships
Reported to have virions that are serologically related to those of
beet curly top hybrigeminivirus, however this virus is transmitted by the
treehopper Micrutalis malleifera (Hemiptera: Membracidae) and fails to
infect Beta vulgaris, whereas beet curly top hybrigeminivirus is
transmitted by the leafhopper Circulifer tenellus (Hemiptera:
Cicadellidae).
