Genetic Composition of Pepino mosaic virus Population in North American Greenhouse Tomatoes

Ecological and genetic determinants of Pepino Mosaic Virus emergence.

UNLABELLED Virus emergence is a complex phenomenon, which generally involves spread to a new host from a wild host, followed by adaptation to the new host. Although viruses account for the largest fraction of emerging crop pathogens, knowledge about their emergence is incomplete. We address here the question of whether Pepino Mosaic Virus (PepMV) emergence as a major tomato pathogen worldwide c...

Mixed infections of Pepino mosaic virus strains modulate the evolutionary dynamics of this emergent virus.

Pepino mosaic virus (PepMV) is an emerging pathogen that causes severe economic losses in tomato crops (Solanum lycopersicum L.) in the Northern hemisphere, despite persistent attempts of control. In fact, it is considered one of the most significant viral diseases for tomato production worldwide, and it may constitute a good model for the analysis of virus emergence in crops. We have combined ...

Population genetic structure of North American thinhorn sheep (Ovis dalli).

The thinhorn sheep (Ovis dalli ssp.) provides a rare example of a North American large mammal that occupies most of its native range and maintains close to ancestral population size. There are currently two recognized subspecies, Dall's sheep (O. d. dalli) and Stone's sheep (O. d. stonei), the validity of which remains uncertain. We investigated the spatial genetic structure of thinhorn sheep p...

Effectiveness of Chemo- and Thermotherapeutic Treatments on Pepino mosaic virus in Tomato Seed

In the 10 years since its first report to infect tomato (Solanum lycopersicum L.) in 1999 (19), Pepino mosaic virus (PepMV), a Potexvirus sp., has become an important virus infecting greenhouse tomato plants in Europe (2,5,6,13–16), North America (3,10,12), South America (8,18), and Asia (20). Although commercial tomato seed has long been suspected to be a source of initial virus inoculum, earl...
