Pepino Mosaic Virus: A Globally Important Tomato Pathogen and a Rising Model in Molecular Virology.

ABSTRACT:

Taxonomy

Pepino mosaic virus (PepMV); species: Potexvirus pepini; family: Alphaflexiviridae; order: Tymovirales.

Virion and genome properties

PepMV virions are rod-shaped, non-enveloped, and flexuous particles. They encapsidate a monopartite, single-stranded, positive-sense RNA genome of approximately 6.4 kb, that encodes, in the sense orientation, a replicase, three triple gene block proteins, and the coat protein.

Host range

PepMV is widespread and causes a major disease in intensive tomato crops. Natural infections have also been reported in kachuma (also known as cachum or pepino dulce; Solanum muricatum), basil, wild tomato species, and weeds from various families growing near affected tomato crops. Experimentally, PepMV can infect plants of virtually all Solanac
