Nomenclature

Acronym

GAV

ICTV decimal code

39.0.1.T.006

Host range and symptoms

Natural host range and symptoms

Symptoms persist.

Vitis vinifera - no leaf symptoms, fruit are unpalatable because of small sugar content.

Transmission

Transmitted by means not involving a vector. Virus not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants.

Geographical distribution

Found, but with no evidence of spread, in Japan.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Vitis vinifera - no leaf symptoms, fruit unpalatable.

Maintenance and propagation hosts

Vitis vinifera.

Susceptible host species

• Vitis vinifera

Insusceptible host species

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Namba et al. (1991).

Particle morphology

Virions isometric; not enveloped; 28 nm in diameter; angular in profile; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 110 S. Density 1.38 g cm^-3 in CsCl.

Biochemical properties

Virions contain 30 % nucleic acid.

Genome consists of RNA; single-stranded; largest (or only) genome part 6.8 kb.

Features of proteins

Virion protein(s) one; M_r 23000; coat protein.

Cytopathology

Virions found in phloem and companion cells in sieve tubes; in cytoplasm, in nuclei, and in cell vacuoles. Inclusions present in infected cells; are crystals in the cytoplasm; they contain virions. Other cellular changes: necrosis of phloem cells.

Taxonomy and relationships

Possible Luteovirus

Virus(es) with serologically unrelated virions

Barley yellow dwarf and potato leafroll viruses.
