Nomenclature

Synonyms

chilli mottle virus, Indian pepper mottle virus.

Acronym

IPMV

ICTV decimal code

57.0.1.T.045

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Capsicum annuum - systemic mottling and leaf malformation, including narrowing and split tips.

Transmission

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

Ecology and control

Studies reported by Sandhu and Chohan (1979).

Geographical distribution

Spreads in India.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show systemic mosaics, mottles, ringspots or necrosis showing first on youngest leaves usually as vein clearing.

Diagnostically susceptible host species and symptoms

• Capsicum annuum - systemic mottle.
• Capsicum frutescens cv. Tabasco - necrotic local lesions, then systemic necrosis.
• Physalis floridana - systemic mottle.
• Nicotiana glutinosa, N. tabacum cv. Turkish - systemic mottle.
• Chenopodium amaranticolor - necrotic local lesions.

Diagnostically insusceptible host species

Chenopodium album, Gomphrena globosa, Datura stramonium, Nicotiana rustica, Petunia × hybrida.

Maintenance and propagation hosts

Cucurbita pepo.

Assay hosts (Local lesions or Whole plants)

Physical and biochemical properties

Properties of particles in sap

TIP: 50-55 °C. LIV: 3 days. DEP: log₁₀ minus 2.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Pepper mottle and potato Y viruses.

Virus(es) with serologically unrelated virions

Tobacco mosaic, tobacco etch, potato X and cucumber mosaic viruses.

Best tests for diagnosis

Indian pepper mottle virus (PeMV-I) can be distinguished from tobacco mosaic (TMV), cucumber mosaic (CMV) and potato X virus (PVX) viruses which naturally infect chilli (Capsicum annuum) in India by host range, serology and virion morphology. In India chilli (Capsicum annuum) is also infected by potyviruses such as potato Y virus (PVY; Jayarajan and Ramakrishna, 1969; Joshi and Bhargava, 1962; Khatri and Sekhon, 1984) and pepper veinal mottle (PVMV; Bidhari and Reddy, 1981; Prasadrao, 1976). PeMV-I, as reported by Sandhu and Chohan (1979) from the Punjab, can be distinguished from the potyviruses by the reactions of six pepper cultivars (Avelar, Agronomico-S, Yolo Y, Early Calwonder, Fla-23-1-7 and Tabasco) as recommended by Zitter (1973); its host range is similar to that reported by Purcifull et al. (1975).
