Data collated by R.W. Fulton, 1985.

Nomenclature

Synonyms

cherry chlorotic ringspot virus, peach stunt virus, sour cherry yellows virus.

Acronym

PDV

ICTV decimal code

10.0.2.04.01

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Prunus domestica - leathery, strap-like leaves.
• Prunus cerasus - leaf yellowing and abscission.
• Prunus persica - stunting.

Transmission

Transmitted by means not involving a vector. Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; transmitted by seed (to 10% in Prunus cerasus); transmitted by pollen to the seed and transmitted by pollen to the pollinated plant.

Geographical distribution

Probably distributed worldwide.

Experimental host range

Many (>9) families susceptible.

Diagnostically susceptible host species and symptoms

• Cucumis sativus - small chlorotic local lesions; systemic mosaic.
• Cucurbita maxima - interveinal chlorosis.
• Sesbania exaltata - small dark local lesions in cotyledons; not systemic.
• Crotalaria spectabilis - small dark local lesions.
• Momordica balsamina - chlorotic local lesions; systemic mottle.
• Tithonia speciosa - prominent chlorotic lines and rings.
• Phlox drummondii - systemic mottle.
• Thunbergia alata - systemic chlorotic rings.
• Melilotus officinalis - systemic mottle.

Physical and biochemical properties

Properties of particles in sap

TIP: 45-54 °C (in extracts with antioxidant). LIV: 0.5-0.75 days (12-18 hours). DEP: log₁₀ minus 2-3. Electron microscopy: Fixation in 0.5% acrolein plus 0.5% glutaraldehyde.

Particle morphology

Virions isometric and bacilliform; not enveloped; 19-20 nm in diameter; 20 nm in length, or 23 nm in length, or 26 nm in length, or 38 nm in length (some 20×73 nm); rounded in profile; without a conspicuous capsomere arrangement.

Physical properties

Five sedimenting components in purified preparations (Halk and Fulton, 1978); sedimentation coefficient of the fastest 113 S; of the other(s) 75 S, or 81 S, or 85 S, or 98 S (the 98 and 113 S virions contain the genome). Density 1.33 g cm^-3 in CsCl (when fixed in formaldehyde). A₂₆₀/A₂₈₀ ratio 1.56 (for each).

Biochemical properties

Virions contain 14 % nucleic acid; 86 % protein; 0 % lipid.

Genome consists of RNA; single-stranded. Genomic nucleic acid isolated by Halk and Fulton (1978).
