ICTV decimal code

57.0.1.0.060

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Saccharum officinarum - mosaic.
• Sorghum bicolor - mosaic, red-leaf.

Transmission

Transmitted by a vector; an insect; Aphididae. Transmitted in a non-persistent manner.

Experimental host range

Few (<3) families susceptible.

Susceptible host species

• Saccharum officinarum
• Sorghum bicolor

Families containing susceptible hosts

• Gramineae (2/2)

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 702-714 nm. Axial canal obscure.

NCBI sequence data (Entrez search)

Sequence database accession code(s)

• U07219 Em(40)_vi:SM07219 Gb(84)_vi:SMU07219 Sorghum mosaic virus strain Sugarcane mosaic virus H polyprotein (nuclear inclusion II protei 1 sequence).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm. Inclusions present in infected cells; are pinwheels and unusual in shape; bundles, scrolls, tubes and laminated aggregates; group I inclusions (Edwardson, 1974).

Taxonomy and relationships

Potyvirus: Potyviridae

Additional comments on relationships

This virus is one of a complex of potyviruses infecting tropical grasses. These have been shown by immunoblot and virion protein sequencing to fall into four species; maize dwarf mosaic, sugarcane mosaic, sorghum mosaic and Johnson grass mosaic. For details also check descriptions of the other three species.
