Interpretive Summary:

Technical Abstract: Ammi majus, also known as false Queen Anne’s lace or bishop’s flower, is an annual in the Apiaceae. A. majus is native to the Mediterranean but it is cultivated in major growing areas including Holland, Israel, the UK, and the US and is frequently used in the floral trade to add a lacy look to bouquets. A. majus is frequently confused with roadside Queen Anne’s lace, Daucus carota, which is a common weed in the US. Virus-like symptoms including mosaic, generalized chlorosis, vein clearing, interveinal chlorosis, leaf deformities, and leaf rugosity were observed in two cut-flower production fields in south Florida in March 2005. Cylindrical inclusions typical of a potyvirus infection and testing with a commercially-available enzyme-linked immunosorbent assay for multiple potyvirus species indicated the presence of a potyvirus. An additional inclusion body in A. majus and symptoms on mechanically inoculated Chenopodium quinoa indicated that a second virus may also be present. There are no prior reports of a virus infecting A. majus in Florida. Elsewhere, Anthriscus latent virus, Caraway latent virus, Celery mosaic virus, Parsley green mottle virus, and Parsnip leafcurl virus have been reported.
