Weeds, as ancillary hosts, pose disproportionate risk for virulent pathogen transfer to crops

Linde, Celeste C; Smith, Leon M; Peakall, Rod

Description

BACKGROUND: The outcome of the arms race between hosts and pathogens depends heavily on the interactions between their genetic diversity, population size and transmission ability. Theory predicts that genetically diverse hosts will select for higher virulence and more diverse pathogens than hosts with low genetic diversity. Cultivated hosts typically have lower genetic diversity and thus small effective population sizes, but can potentially harbour large pathogen population...[Show more]
