Data collated by J.R. Diaz-Ruiz, I. Garcia Luque and M.T. Serra, 1992.

Nomenclature

Synonyms

tobacco mosaic virus - P11 pepper isolate.

Acronym

PaMMV

ICTV decimal code

71.0.1.0.006

Host range and symptoms

Natural host range and symptoms

Symptoms persist.

Capsicum annuum - mild mosaic.

Transmission

Virus transmitted by mechanical inoculation; possibly transmitted by seed.

Geographical distribution

Spreads in the Eurasian region; the Netherlands.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show small chlorotic or necrotic local lesions, mosaic and stunting.

Diagnostically susceptible host species and symptoms

• Capsicum spp. with either L⁺L⁺ or L¹L¹ genotypes - mild mottle or mosaic.
• Nicotiana benthamiana - mosaic, stunting.
• Nicotiana clevelandii - mosaic, malformation.
• Solanum pseudocapsicastrum - mosaic.

Diagnostically insusceptible host species

Lycopersicon esculentum.

Maintenance and propagation hosts

Capsicum annuum, Nicotiana benthamiana and N. clevelandii.

Assay hosts (Local lesions or Whole plants)

Capsicum annuum (W), C. frutescens (L), Nicotiana clevelandii (W), N. sylvestris (L), N. tabacum cv Xanthi (L).

Susceptible host species

• Capsicum annuum
• Capsicum frutescens
• Nicotiana benthamiana
• Nicotiana clevelandii
• Nicotiana glutinosa
• Nicotiana sylvestris
• Nicotiana tabacum
• Petunia × hybrida
• Solanum melongena
• Solanum pseudocapsicastrum
• Trifolium subterraneum

Insusceptible host species

• Lycopersicon esculentum

Families containing susceptible hosts

Sources of host-range data

Tobias et al. (1982).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains many virions.

Particle morphology

Virions rod-shaped; not enveloped; usually straight; with a clear modal length.

Biochemical properties

Virions contain 5 % nucleic acid; 95 % protein.

Genome consists of RNA; single-stranded; linear. Total genome size 6.5 kb. Genome unipartite; largest (or only) genome part 6.5 kb. Genomic nucleic acid isolated by Alonso et al. (1991). Infectivity retained when deproteinised with phenol or detergent. Additional factor not required for infectivity.

NCBI sequence data (Entrez search)

Sequence database accession code(s)

• X72586 Gb(84)_vi:PMMVCP Paprika mild mottle virus (Pepper strain P11) coat protein gene and 3´ non-coding region. 7/9.

Features of proteins

Virion protein(s) one; M_r 17706; coat protein.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves; in cytoplasm.

Taxonomy and relationships

Tobamovirus

Virus(es) with serologically unrelated virions

Tobacco and tomato mosaic tobamoviruses.
