Nomenclature

Acronym

PrMoV

ICTV decimal code

57.0.1.T.074

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Primula malacoides - mild mosaic of green and chlorotic areas, flower colour breaking and stunting.

Transmission

Transmitted by a vector; an insect; Aphis gossypii, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation.

Ecology and control

Studies reported by Singh et al. (1970); Mali (1985).

Geographical distribution

Spreads in India (in Delhi).

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor - chlorotic local lesions.
• C. album - necrotic local lesions.
• Datura stramonium - systemic mild mottle, young leaves filiform, malformed and with enations.
• Gomphrena globosa, Nicotiana glutinosa, N. rustica, N. tabacum, Petunia alba - systemic mild mottle, vein-clearing.

Diagnostically insusceptible host species

Chenopodium quinoa, Datura metel, Nicandra physalodes, Solanum nigrum and Zinnia elegans.

Sources of host-range data

Physical and biochemical properties

Properties of particles in sap

TIP: 60-65 °C. LIV: 2 days. DEP: log₁₀ minus 1. Leaf sap contains few virions.

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 720-745 nm.

Taxonomy and relationships

unassigned potyvirus

Additional comments on relationships

PMtV shows some similarities to tobacco etch (TEV) and datura enation mosaic viruses (DEMV).

Best tests for diagnosis

Primula mosaic caused by alfalfa mosaic virus (AMV) in India (Nagaich and Giri, 1968) can be distinguished from primula mottle virus (PMtV) by its host range, virion morphology and by serology.
