Data collated by E.D. Ammar, 1989.

Nomenclature

Synonyms

maize yellow stripe virus, maize fine stripe virus, maize chlorotic stunt virus.

ICTV decimal code

69.0.1.T.DE.2

Host range and symptoms

Natural host range and symptoms

Symptoms persist, or vary cyclically over a few weeks.
• Zea mays, Sorghum vulgare, S. bicolor, Triticum aestivum, Hordeum vulgare - yellow striping or chlorosis.

Transmission

Transmitted by a vector; an insect; Cicadulina chinai; Cicadellidae. Transmitted in a persistent manner. Virus retained when the vector moults; not transmitted by mechanical inoculation; not transmitted by contact between plants.

Ecology and control

Studies reported by Ammar et al. (1987); Ammar et al. (1989).

Geographical distribution

Spreads in Egypt.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show systemic mosaics.

Diagnostically susceptible host species and symptoms

• Zea mays, Sorghum vulgare, S. bicolor, Triticum aestivum, Hordeum vulgare - yellow leaf striping.

Maintenance and propagation hosts

Zea mays, Sorghum vulgare, S. bicolor, Triticum aestivum, Hordeum vulgare.

Assay hosts (Local lesions or Whole plants)

Zea mays (W).

Susceptible host species

• Hordeum vulgare
• Sorghum bicolor
• Sorghum vulgare
• Triticum aestivum
• Zea mays

Families containing susceptible hosts

• Gramineae (5/5)

Sources of host-range data

Aboul-Ata and Ammar (1985); Ammar et al. (1987, 1989).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains many virions. Electron microscopy: UA or PTA may be used without fixation.

Purification method

Ammar et al. (1990).

Particle morphology

Virions filamentous; usually flexuous; 5-7 nm wide. Axial canal obscure.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 87 S.

Features of proteins

Virus-coded non-virion proteins isolated (Ammar et al. (1990)); one protein found. M_r 13800.

Cytopathology

Virions found in leaves, mesophyll, vascular parenchyma, phloem and companion cells; in cytoplasm. Inclusions present in infected cells; are amorphous X-bodies; they contain virions (helical filaments are found). Other cellular changes: tubular helical structures which are found abundantly in cytoplasmic inclusions, sometimes associated with mitochondria.

Taxonomy and relationships

Possible Tenuivirus

Virus(es) with serologically related virions

Maize mottle - chlorotic stunt.

Virus(es) with serologically unrelated virions

Maize stripe, maize chlorotic dwarf, maize chlorotic mottle, maize dwarf mosaic (A, B or D), maize streak and maize mosaic viruses (Ammar et al., 1990).

Additional comments on relationships

Like tenuiviruses it has thin filamentous virions and similar non-virion proteins, but differs in cytopathology and in being transmitted by a leafhopper and not a planthopper.

Best tests for diagnosis

Transmission with Cicadulina chinai (leafhoppers).
