Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Passiflora edulis - mosaic and leaf crinkling.

Transmission

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

Ecology and control

Geographical distribution

Spreads in Peru.

Experimental host range

Sources of host-range data

Fribourg et al. (1987).

Physical and biochemical properties

Properties of particles in sap

TIP: 90 °C. LIV: 90 days. DEP: log₁₀ minus 10 (in Chenopodium quinoa sap). Leaf sap contains many virions.

Purification method

Fribourg et al. (1987); Fribourg and Nakashima (1984).

Particle morphology

Virions rod-shaped; not enveloped; usually straight; with a clear modal length; of 304 nm; 18 nm wide. Axial canal obvious.

Physical properties

One sedimenting component in purified preparations.

Features of proteins

Virion protein(s) two; M_r of the larger 17400. M_r of 2nd largest 15900. Method of preparation: Fribourg et al. (1987).

Cytopathology

Virions found in mesophyll, epidermis, vascular parenchyma and xylem; in cytoplasm. Inclusions present in infected cells; are crystals in the cytoplasm, amorphous X-bodies, and unusual in shape; tonoplast-associated small vesicles; they contain virions (in the crystals), or they do not contain virions (in the others).

Taxonomy and relationships

Possible Tobamovirus

Virus(es) with serologically related virions

Cucumber green mottle mosaic, frangipani mosaic, odontoglossum ringspot, tobacco mosaic and ullucus tobamoviruses, but distantly.

Virus(es) with serologically unrelated virions

Ribgrass mosaic and Sammons' opuntia tobamoviruses.
