Leek yellow
stripe potyvirus
Index
Data collated by L. Bos, 1987.
Nomenclature
Acronym
ICTV decimal code
Host range and symptoms
First reported
in Allium porrum; from Germany and several European countries; by Bos
et al. (1978).
Natural host range and symptoms
Symptoms persist.
- Allium porrum - yellow leaf striping.
- Allium cepa
var. ascalonicum, A. cepa - rarely infected.
Transmission
Transmitted by a vector; an insect;
Aphididae. Transmitted in a non-persistent manner. Virus transmitted by
mechanical inoculation; not transmitted by contact between plants; not
transmitted by seed.
Ecology and control
Studies reported by
Bos et al. (1975).
Geographical distribution
Spreads
in the Eurasian region; New Zealand.
Experimental host range
Several (3-9) families
susceptible.
Diagnostically susceptible host species and
symptoms
- Allium porrum - yellow leaf stripes.
- Chenopodium amaranticolor, C. quinoa - chlorotic local lesions,
becoming green rings when leaves senesce.
- Celosia argentea - brown
necrotic local lesions.
Diagnostically insusceptible host species
Allium fistulosum, Cucumis sativus, Nicotiana clevelandii, N.
megalosiphon, Petunia × hybrida.
Maintenance and propagation
hosts
Assay hosts (Local lesions or Whole plants)
Chenopodium quinoa (L), C. amaranticolor (L).

Sources of host-range data
Verhoyen
and Horvat (1973); Bos et al. (1978); Graichen (1978).
Physical and
biochemical properties
Properties of particles in sap
TIP:
50-60 °C. LIV: 3-4 days. DEP: log10 minus 2-3. Leaf sap contains many
virions.
Purification method
Huttinga
(1975); Bos et al. (1978).
Particle morphology
Virions filamentous; not enveloped;
usually flexuous; with a clear modal length; of 820 nm. Axial canal obscure.
Basic helix obscure.
Physical properties
One sedimenting component in purified
preparations. Density 1.326 g cm-3 in sucrose.
Sequence database accession code(s)
- X89711
Em(44)n:Lyspvpoly Gb(90)n:Lyspvpoly Leek yellow stripe potyvirus genomic RNA for
partial nuclear inclusion protein and coat protein.
Features of proteins
Virion protein(s) one;
Mr 34000; coat protein. Method of preparation: Huttinga (1975).
Cytopathology
Virions found in leaves. Inclusions present
in infected cells; are pinwheels and unusual in shape; large fibrous or granular
cytoplasmic inclusion bodies.
Taxonomy and
relationships
Virus(es) with serologically related virions
Onion yellow dwarf virus.
Best tests for diagnosis
Onions
infected by leek yellow stripe virus (LYSV) with difficulty, and leek is very
resistant to onion yellow dwarf virus (OYDV). Allium fistulosum is immune
to LYSV but infected symptomlessly by OYDV. LYSV gives local lesions in
Chenopodium amaranticolor and C. quinoa. LYSV differs from shallot
latent carlavirus in virion size and morphology and in forming larger and later
local lesions on Chenopodium amaranticolor and C. quinoa.
