Apium virus Y Apium virus Y "Apium virus Y" (ApVY) is a plant pathogenic virus in the genus "Potyvirus" and the virus family "Potyviridae". Apium virus Y is a recently described member of the potyvirus family. It was first found in Australia in 2002 in poison hemlock ("Conium maculatum": an immigrant weed in Australia). A survey of native and weed species in the family Apiaceae found ApVY to be widespread in Australia. In addition, this survey and others found two other potyviruses. One was a well-known potyvirus infecting the Apiaceae, "Celery mosaic virus" (CeMV). CeMV has been found in celery ("Apium graveolens") crops
