Nomenclature

Acronym

FDV

ICTV decimal code

60.0.7.1.001

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Saccharum spp. - leaf deformation and leaf galls.

Transmission

Transmitted by a vector; an insect; Perkinsiella saccharicida, P. vitiensis and P. vastatrix; 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.

Geographical distribution

Spreads in the African region and the Pacific region (New Britain and the New Hebrides); Australia, Fiji, Papua New Guinea, the Philippines, Thailand, and Western Samoa. Found, but with no evidence of spread, in the U.S.A.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Saccharum spp., Sorghum spp., Zea mays - enations on deformed leaves and leaf sheaths.

Susceptible host species

• Saccharum officinarum
• Sorghum bicolor
• Zea mays

Families containing susceptible hosts

• Gramineae (3/3)

Sources of host-range data

Hutchinson et al. (1972).

Physical and biochemical properties

Properties of particles in sap

Leaf sap galls contains many virions, or contains few virions (in leaves). Electron microscopy: stain with UA.

Purification method

Van der Lubbe et al. (1979).

Particle morphology

Virions isometric; 71 nm in diameter (intact virions), or 54 nm in diameter (subvirions); rounded in profile; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations.

Biochemical properties

Virions 0 % lipid.

Genome consists of RNA; double-stranded; linear. Total genome size 27.109 kb (pairs). Genome of 10 parts (named S1-10); largest (or only) genome part 3.998 kb (pairs); the 2nd largest 3.385 kb (pairs); the 3rd largest 3.38 kb (pairs); the 4th largest 3.38 kb (pairs); the 5th largest 3.1 kb (pairs); the 6th largest and other parts 2.5 kb (pairs; also 2.190, 1.732, 1.724 and 1.720 kb pairs).

Features of proteins

Virion protein(s) at least three (in the core); M_r 145000-150000. M_r of 2nd largest 125000-129000. M_r of 3rd largest 36000-39000. Method of preparation: Van der Lubbe et al. (1979).

Cytopathology

Virions found in gall tissue; in cytoplasm and in cell vacuoles. Inclusions present in infected cells; are unusual in shape; round, containing strands and amorphous material; they contain virions. Other cellular changes: proliferations in both phloem and xylem.

Taxonomy and relationships

Fijivirus: Reoviridae (the type species)
