[5] Two different strains of ApVY were found in Washington state, one in domestic celery crops and other in the weed poison hemlock.

ApVY was recently also found in Balıkesir province of Turkey, and might be distributed widely there as all 10 symptomatic parsley samples were tested positive using RT-PCR detection method.

The study also successfully generated a new pair of primer for amplification of 1066 bp of ApVY genome, including the complete coat protein (CP) gene.

In another host range study, the virus causes local lesions and other symptoms on Chenopodium quinoa, Blitum capitatum, and Beta macrocarpa which belong to Amaranthaceae.

[11] Symptoms reported included mosaic, vein clearing or banding, necrotic/chlorotic line patterns and stunting.
