First report of Plantago asiatica mosaic virus in Hungary
During a survey, unusual symptoms were observed during winter 2013 on Lilium plants in a 2-ha greenhouse in Dabas city, Hungary. Extensive necrotic areas were observed along the veins of lily leaves. The lower leaves withered, flower production declined, and the plants gradually died. In the case of cv. ‘Rialto’, the disease incidence reached more than 50%, and 30% infection was observed on cv. ‘Conca d’Or’ during the visual inspection of 10 000 plants. Laboratory analysis (electron microscopy, RT-PCR, sequencing) confirmed the presence of Plantago asiatica mosaic virus (Potexvirus, PlAMV) in symptomatic plants. This is the first time that this virus is detected in Hungary. Based on sequences similarity of PlAMV isolates detected in Hungary with a Dutch isolate, and the fact that the lily bulbs originated from the Netherlands, it is suspected that the import of bulbs from the Netherlands was the source of infection.
The situation of Plantago asiatica mosaic virus in Hungary can be described as follows: Present, first found in 2013 in a Lilium greenhouse in Dabas (Pest county).
