Index
Data collated by D.-E. Lesemann, 1991.
Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Limonium sinuatum; from southern Germany; by Lesemann et al.
(1979).
Natural host range and symptoms
Symptoms persist.
Symptoms light green mosaic, stunting, narrow leaves, deformation of leaves.
- Limonium sinuatum.
Transmission
Virus transmitted by mechanical inoculation.
Geographical distribution
Found, but with no evidence of
spread, in southern Germany.
Experimental host range
Several (3-9) families
susceptible. Experimentally infected plants mostly show local lesions, mosaic.
Diagnostically susceptible host species and symptoms
- Chenopodium quinoa - systemic, chlorotic, later
necrotic spots.
- C. amaranticolor, C. murale, C. foliosum - local
lesions.
- Gomphrena globosa, Amaranthus retroflexus - symptomless.
- Lathyrus odoratus - light mosaic.
- Nicotiana clevelandii
- faint mottle.
- Phaseolus vulgaris - yellow mosaic.
- Vicia faba - mosaic.
Diagnostically insusceptible host
species
Beta vulgaris, Nicotiana glutinosa, N. tabacum cv.
Samsun, Pisum sativum cv. Kelvex, Zinnia elegans.
Maintenance and propagation hosts
Assay hosts (Local lesions or Whole plants)
Chenopodium quinoa (W), C.
amaranticolor (L), Phaseolus vulgaris (W).

Physical and
biochemical properties
Properties of particles in sap
TIP:
54-56 °C. LIV: 15 days. DEP: log10 minus 5-6. Leaf sap contains few virions.
Electron microscopy: glutaraldehyde fixation reduces virion breakage.
Purification method
Particle morphology
Virions filamentous; not enveloped;
usually flexuous; with a clear modal length; of 748 nm. Axial canal obscure.
Basic helix obscure.
Features of proteins
Virion protein(s) one;
Mr 31000; coat protein. Method of preparation: Lesemann et al.
(1979): SDS - polyacrylamide electrophoresis.
Cytopathology
Virions found in leaves, mesophyll and the
epidermis; in cytoplasm. Inclusions present in infected cells; are crystals in
the cytoplasm, crystals in the nucleus, and pinwheels; and are hypertrophied
mitochondria; they do not contain virions. Other cellular changes: pinwheels of
laminated aggregate type, small electron dense crystals in nucleolus and
cytoplasm and hypertrophied mitochondria (Lesemann et al., 1979).
Taxonomy and
relationships
Virus(es) with serologically related virions
Bean yellow mosaic, bean common mosaic, clover yellow vein, gloriosa
stripe, pea seed borne mosaic and potato Y viruses.
Virus(es) with
serologically unrelated virions
Best tests for diagnosis
Systemically infects Chenopodium quinoa and fails to infect Pisum
sativum unlike bean yellow mosaic virus. Little or no reaction with antisera
to clover yellow virus (CYVV) and fails to produce local lesions on cucumber
like CYVV.
