Host range and symptoms

Natural host range and symptoms

Symptoms vary cyclically over a few weeks.

Sources of host-range data

Chagas et al. (1984); Oliveira (1986).

Physical and biochemical properties

Properties of particles in sap

TIP: 60-65 °C. LIV: 7 days. DEP: log₁₀ minus 5. Leaf sap contains many virions.

Particle morphology

Virions isometric; not enveloped; 30 nm in diameter; angular in profile; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 129 S.

Biochemical properties

Virions contain 15 % nucleic acid.

Genome consists of RNA; single-stranded.

Features of proteins

Virion protein(s) one; M_r 35500; coat protein.

Cytopathology

Virions found in all parts of the host plant; in cytoplasm and in cell vacuoles. Inclusions absent from infected cells. Other cellular changes: filamentous material within the cristae of mitochondria.

Taxonomy and relationships

(ungrouped)

Virus(es) with serologically unrelated virions

Tymoviruses, comoviruses, cucumoviruses, sobemoviruses, ilarviruses, mimosa mosaic virus and maize rayado fino virus.

Best tests for diagnosis

Serology, symptoms in Passiflora spp. and host range. (N.B. CMV infects species outside Passifloraceae). Passionfruit yellow mosaic tymovirus produces bright yellow mosaic in most Passiflora spp., but is not serologically related.
