Hosts

Common ash tree (Fraxinus excelsior) and flowering ash trees (Fraxinus ornus) are so far the only known natural host species of FraxGCV1 and FraxGCV2 (Rehanek et al. 2024, Bejerman et al. 2023). The non-native Fraxinus ornus is increasingly planted in German cities as a climate-tolerant tree. To our knowledge, no screening or bioassay has been performed to determine the host range of this virus.
