Gaafar & Heiko Ziebell Julius Kühn-Institut, Institute of Epidemiology and Pathogen Diagnostics, Braunschweig Email of corresponding author: yahya.gaafar@julius-kuehn.de Legumes are important crops with high nutritional value for both human and animal consumption. They are suscepti-ble to many viral diseases. The last sea-son showed a high incidence of viral diseases on leguminous crops in Ger-many and Austria. Analyses of sympto-matic plant samples revealed that infec-tions were resulting mainly from pea enation mosaic virus (PEMV) and pea necrotic yellow dwarf virus (PNYDV). Nanoviruses such as PNYDV, are multi-component circular ssDNA viruses. They are transmitted by aphids in a circula-tive, persistent manner and infect mainly legumes. Interestingly, this transmission requires a viral helper fac-tor (HF). In this study, we aim to investigate the interactions between Nanoviruses, their hosts and their aphid vectors. In particu-lar we want to investigate the role of the HF during aphid transmission as well as studying the aphid feeding behaviour on infected and healthy plants. Currently we are characterising the genetic varia-tion of legume viruses in Germany using next-generation sequencing technolo-gies. 14 Berichte aus dem Julius Kühn-Institut 186
