Potato virus X (PVX) has a wide natural host range,
occurring in at least 62 plant species of 27 families. In
particular, the virus can infect the economically important
solanaceous crops (potato, tomato, tobacco), winter cherry, turnip,
artichoke, grapevine, and red clover. Many of the natural hosts of
PVX are weeds as well. The virus mainly spreads via mechanical
transmission, but limited transmission has been observed by biting
insect vectors.
