Prune Dwarf Virus (PDV) The primary hosts of PDV are cherry, plum and peach. PDV can replicate in many tissues and is pollen transmissible. Some strains may find a natural reservoire in hedges of Prunus spinosa , from where other Prunus species flowering at the same time may be contaminated. It exists in distinct strains causing demaging lesions and necrotic spots on cherry leaves and stunting of peach and plum trees. In some apricots it can induce gummosis on the trunk. On sweet cherry the infection rate can be above 30 % without major economic impact, since most of the isolates are not very virulent or epidemic. Sour cherry trees are in contrast very susceptible. Trees become skeletal and defoliated with low yield. Nomenclature and Host Range (VIDE database) Sequence Info (NCBI database) Isolates in the Vienna Collection Detection methods
