Data collated by A.A. Brunt and K. Bock, 1987.

Nomenclature

ICTV decimal code

79.0.P.DE.23

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Zea mays - yellow striping along leaf veins but no apical bending or stunting, like that caused by maize stripe virus.

Transmission

Transmitted by a vector; an insect; Peregrinus maidis; Delphacidae. Transmitted in a persistent manner. Virus not transmitted by mechanical inoculation; not transmitted by contact between plants.

Ecology and control

Studies reported by Kulkarni (1973); Smith (1936).

Geographical distribution

Spreads in Kenya and Tanzania (symptoms are swamped by maize streak virus, which is widespread, so this virus may occur more commonly (Kulkarni, 1973)).

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Zea mays (hybrid 511, hybrid 613B, Wisconsin 641AA) - small chlorotic spots at leaf bases, followed by vein chlorosis and mottling.

Diagnostically insusceptible host species

Chenopodium amaranticolor, Chenopodium quinoa, Glycine max, Petunia × hybrida, Phaseolus vulgaris.

Maintenance and propagation hosts

Zea mays.

Assay hosts (Local lesions or Whole plants)

Zea mays (W).

Susceptible host species

• Zea mays

Insusceptible host species

• Chenopodium amaranticolor
• Chenopodium quinoa
• Glycine max
• Petunia × hybrida
• Phaseolus vulgaris

Families containing susceptible hosts

• Gramineae (1/1)

Families containing insusceptible hosts

• Chenopodiaceae (2/2)
• Leguminosae-Papilionoideae (2/2)
• Solanaceae (1/1)

Sources of host-range data

Kulkarni (1973); Storey (1936).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Kulkarni (1973).

Particle morphology

Virions isometric; not enveloped; 34 nm in diameter; rounded in profile; without a conspicuous capsomere arrangement.

Taxonomy and relationships

(ungrouped)

Virus(es) with serologically unrelated virions

Cucumber mosaic, maize mottle chlorotic stunt and maize streak viruses.

Best tests for diagnosis

Maize line virus sometimes occurs together with maize streak and/or sugarcane mosaic viruses.
