Confirming infection of hop plants inoculated with Verticilium nonalfalfae

Hop (Humulus lupulus L.) is grown mostly as flavouring and bittering ingredient for beer and is also appreciated in the herbal and cosmetic industry, as well as in pharmacology. Among several diseases that damage hop growing, the most devastating in European hop production is verticillium wilt, caused by the soil-borne fungal pathogen Verticillium nonalfalfae. Colonization pattern and differential expression of selected genes after artificial infection of susceptible and resistant hop cultivars with V. nonalfalafae in stems and roots have been analysed recently Svara et al., 2019. Here, we present the dataset related to verification of plant samples infections after artificial inoculation (fungi- and mock-inoculated). After inoculation plant samples were tested for the positive infection by PCR amplification of the V. nonalfalfae ITS DNA region with species specific primers developed and optimised for this purpose.
