Nomenclature

Synonyms

cereal striate mosaic virus (Matthews, 1982).

Acronym

BYSMV

Strains

maize sterile stunt virus (Greber, 1982; 1983a and b; 1984a and b; Milne et al., 1986), Moroccan wheat rhabdovirus (Milne et al., 1986), wheat chlorotic streak virus (Signoret et al. 1976), wheat chlorotic streak mosaic virus (Milne et al., 1986; Signoret et al., 1972; 1977).

ICTV decimal code

62.0.4.0.002

Host range and symptoms

Natural host range and symptoms

• Elytrigia repens, Triticum durum, T. compactum, T. aestivum, Zea mays - chlorotic stripes or mosaic.
• Avena sativa, Secale cereale - yellow mosaic, red basal leaves.
• Setaria viridis, Setaria spp. - chlorotic streaks and stripes in leaves; stunting.

Transmission

Transmitted by a vector; an insect; Laodelphax striatellus (Conti 1969a, 1969b, 1974, 1980; Conti and Plumb, 1977; Leclant and Signoret, 1976; Signoret et al., 1976; Signoret et al., 1977). Javesella pellucida transmits the virus experimentally (Conti, 1980); Delphacidae. Transmitted in a persistent manner. Virus retained when the vector moults; multiplies in the vector; transmitted congenitally to the progeny of the vector; not transmitted by mechanical inoculation; not transmitted by seed (Conti, 1980).

Ecology and control

Studies reported by Conti (1969a); Signoret et al. (1976); Conti and Milne, (1977); Amici et al. (1978); Conti (1980) Lockhart and Elyamani (1983).

Geographical distribution

Spreads in the African region, the Eurasian region, the Middle East, and the Pacific region; Australia, France, Iran, Italy, and Morocco.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show chlorosis, reddening.

Diagnostically susceptible host species and symptoms

• Avena sativa cv. Alba - yellow mosaic, reddening of basal leaves.
• Bromus aleutensis, B. arvensis, B. rigidus (=B. maximus) - stunting.
• Hordeum vulgare cv. Delisa - bright yellow mosaic.
• Setaria italica - chlorotic stripes.

Diagnostically insusceptible host species

Digitaria sanguinalis, Echinochloa crus-galli, Festuca pratensis, Holcus lanatus, Phleum pratense.

Maintenance and propagation hosts

Hordeum vulgare.

Assay hosts (Local lesions or Whole plants)

Comments on host-range

Transmitted by the plant hopper vector to 26 of 44 species in Gramineae only (Conti, 1980).

Sources of host-range data

Conti (1969a); Signoret et al., (1976); Conti and Milne (1977); Amici et al., (1978); Conti (1980); Lockhart and Elyamani (1983).

Physical and biochemical properties

Properties of particles in sap

TIP: 50-60 °C. LIV: 1-2 days (at 22ºC and 2-4 days at 5ºC (Conti, 1980)). DEP: log₁₀ minus 2-3. Leaf sap contains few virions. Electron microscopy: fix in glutaraldehyde; unfixed virions disrupt in neutral PTA and UA.

Purification method

Luisoni (1969); Milne and Conti (1986).

Particle morphology

Virions rhabdo- or bullet-shaped; enveloped; with a clear modal length; of 270 nm (Conti, 1969a), but longer in thin sections or UA (Conti and Appiano, 1974; Appiano and Conti, 1973; Conti and Plumb, 1977)); 55 nm wide. Basic helix of nucleocapsid obvious (after envelope has been removed with chloroform, 0.2% Nonidet P 40 or 0.2% Triton X-100); pitch of basic helix 4.4 nm.

Physical properties

One sedimenting component in purified preparations.

Biochemical properties

Genome consists of RNA; single-stranded (Bassi et al., 1980).

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in phloem; in cytoplasm; within membrane-bound cisternae, from which the virus buds, but not found in nucleus or perinuclear space. Inclusions present in infected cells; are viroplasms.

Taxonomy and relationships

Cytorhabdovirus: Rhabdoviridae

Virus(es) with serologically related virions

Moroccan wheat rhabdovirus, wheat chlorotic streak, maize sterile stunt (SDI:2), northern cereal mosaic (SDI:6), digitaria striate and wheat rosette stunt (SDI:6) viruses. Maize sterile stunt (MSSV) is a serotype of BYSMV (2 SDI units) (Greber, 1984b).

Virus(es) with serologically unrelated virions

Festuca leaf streak virus.
