The Celery Virus Y ( scientifically Apium Virus Y , ApVY ) is a plant virus from the genus Potyvirus . It was first isolated in 2002 in plants of the spotted hemlock ( Conium maculatum ) that invasively migrated to Australia . It was isolated in celery ( Apium graveolens ) growing areas in California from two different plant species of the genus angelica ( Angelica , family Apiaceae ), Angelica lucida ("wild celery") and Angelica genuflexa . Its previously proven distribution areas are, besides Australia and North America, New Zealand and possibly Europe.

Experimentally, several plant species of the umbelliferae (Apiaceae), foxtail family ( Chenopodiaceae ) and nightshade family ( Solanaceae ) can be infected. The naturally occurring transmission to umbellifers occurs through the green peach aphid when sucking the sap. Infected plants show leaf chlorosis , stunted and crooked growth.

Genome

The genome of the celery virus Y is 9917  nt long, and encoded in a single open reading frame ( English open reading frame , ORF) for a polyprotein of 3184 amino acids . Comparisons of the genome sequences show a match of up about 26 to 53% with other potyviruses, the most closely related virus, the Celery mosaic virus ( English Celery mosaic virus represents CEMV). It shows serological cross-reactivity with this and is often detected as a co-infection .
