Nomenclature

Acronym

BRRV

ICTV decimal code

15.0.1.0.002

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Vaccinium corymbosum, V. formosum and possibly V. macrocarpon - red ringspots in leaves and older stems; earlier, but decreased, fruit yield.

Transmission

Virus not transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in the USA.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Vaccinium corymbosum - red ringspots in mature leaves of graft-inoculated plants.

Maintenance and propagation hosts

Vaccinium corymbosum.

Susceptible host species

• Vaccinium corymbosum
• Vaccinium formosum
• Vaccinium macrocarpon (possibly)

Families containing susceptible hosts

• Ericaceae (3/3)

Purification method

Gillet and Ramsdell (1984).

Physical and biochemical properties

Particle morphology

Virions isometric; not enveloped; 42-46 nm in diameter; rounded in profile; without a conspicuous capsomere arrangement.

Physical properties

Two sedimenting components in purified preparations; sedimentation coefficient 275 S; of the other(s) 212 S. Density 1.3 and 1.4 g cm^-3 in CsCl. Isoelectric point pH 4.

Biochemical properties

Genome consists of DNA; double-stranded.

Features of proteins

Virion protein(s) one; M_r 44000; coat protein.

Cytopathology

Virions found in leaves and the mesophyll; in nuclei and in unusual sites; but most are within cytoplasmic inclusions. Inclusions present in infected cells; are viroplasms (enclosed within endoplasmic reticulum); they contain virions.

Taxonomy and relationships

Caulimovirus

Virus(es) with serologically unrelated virions

Cauliflower mosaic, carnation etched ring, dahlia mosaic and figwort mosaic viruses.
