Papaya mosaic virus (PapMV) is a plant pathogenic virus in the genus Potexvirus and the family Alphaflexiviridae. PapMV is a filamentous, flexuous rod, 530 nm in length.[1]
The virus is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. The genome has been completely sequenced[2] and is 6656 nucleotides long. It is transmitted by mechanical inoculation. No insect vector is involved and it is not transmitted in seeds.
Mature virions form banded inclusions[3] that can be seen in leaf strips of infected plants[4][5] when stained with either the Orange-Green protein stain or the Azure A nucleic acid stain.[6][7]
