Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Saccharum spp., Sorghum bicolor, Panicum spp., Eleusine spp., Setaria spp., Zea mays - mosaic and/or ringspots, stunting.
• Sorghum halepense (particular strains) - mosaic and/or necrosis.

Transmission

Transmitted by a vector; an insect; Dactynotus ambrosiae, Hysteroneura setariae, Rhopalosiphum maidis, Toxoptera graminum; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by grafting; transmitted by seed; not transmitted by pollen.

Geographical distribution

Probably distributed worldwide. Spreads in Australia.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Saccharum sp. - systemic mosaic.
• Sorghum bicolor - necrotic local lesion, then systemic mosaic, necrosis.
• S. halepense - systemic mosaic.

Physical and biochemical properties

Properties of particles in sap

TIP: 50-60 °C. LIV: 2-4 days. DEP: log₁₀ minus 2-4. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains few virions.

Purification method

Moghal and Francki (1976); Shukla et al. (1989a); Bond and Pirone (1971).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 730-755 nm; 13 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 148-176 S. Density 1.3327 g cm^-3 in CsCl.

Biochemical properties

Virions contain 5.5-6 % nucleic acid; 94-94.5 % protein.

Genome consists of RNA; single-stranded. Total genome size 9.5 kb. Genome unipartite; largest (or only) genome part 9.5 kb.

NCBI sequence data (Entrez search)

Sequence database accession code(s)

• D00094 Gb(84)_vi:MSCVCP Sugarcane mosaic virus (SCMV), the 3´terminal 1782 nucleotides of the genome, encoding the vi
• D00948 Em(40)_vi:MSCCP Gb(84)_vi:MSCCP Sugarcane mosaic virus mRNA for coat protein, 3´-terminal region. 8/92 1,330bp.
• X05040 Em(40)_vi:POSCMVCA Gb(84)_vi:POSCMVCA Sugar cane mosaic virus RNA for capsid/nuclear inclusion protein (3´ terminal genome). 7/89 1 3 sequences.

Features of proteins

Virion protein(s) one; M_r 34998 (328 residues (MDMV-B)). Method of preparation: Francki and McLean (1968).

Cytopathology

Virions found in mesophyll; in cytoplasm and in Golgi apparatus (bundles, scrolls, tubes and laminated aggregates, namely inclusion group III (Edwardson, 1974)). Inclusions present in infected cells; are pinwheels; they do not contain virions. Other cellular changes: alteration of chloroplasts organisation (i.e. small grana with few thylakoids and uniform distribution of intergrana (stromal) lamellae).

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Using electro-blot immunoassay with cross-absorbed polyclonal antibodies against the N-terminus of the virion proteins that the potyviruses infecting sugarcane, maize and sorghum are of four distinct potyviruses: 1) Johnson grass mosaic potyvirus - SCMV-JG and maize dwarf mosaic virus strain O. 2) Maize dwarf mosaic potyvirus - MDMV-A, MDMV-D, MDMV-E and MDMV-F. 3) Sugarcane mosaic potyvirus - MDMV-B, SCMV-A, SCMV-B, SCMV-D, SCMV-E, SCMV-Sc, SCMV-Bc and SCMV-Sabi. 4) Sorghum mosaic potyvirus - SCMV-H, SCMV-I and SCMV-M (Shukla et al., 1989).
