|a The previously reported properties of a small circular RNA isolated from plants of cultivar Starking Delicious with symptoms similar to those of the dapple apple disease induced by Apple scar skin viroid (ASSVd), strongly suggested that it is a distinct viroid species of genus Apscaviroid to which ASSVd also belongs. Nevertheless, the autonomous replication of this novel RNA, termed Apple dimple fruit viroid (ADFVd), and the nature of the symptoms incited when inoculated free of other pathogens that might be present in the original source, were not determined. We addressed these questions by mechanically inoculating purified ADFVd into young apple seedlings (Golden). Dot blot hybridization of leaf extracts collected ten months after inoculation showed the presence of ADFVd in most of the inoculated seedlings, thus proving the ability of this RNA to replicate independently. Material from these ADFVd-infected seedlings grafted onto the ASSVd indicator Starkrimson incited the appearance on the fruit skin of discolored spots more or less depressed which were particularly frequent around the calyx cavity. Apple cultivars such as Gala, Pink Lady, and Braeburn reacted to ADFVd with similar symptoms, occasionally accompanied by scar skin in Braeburn, whereas ADFVd replicated without eliciting any visible symptoms in other apple cultivars such as Golden, or in the pear indicator Fieud 37. No interference in symptom expression or viroid accumulation were observed in plants inoculated first with ASSVd and then with ADFVd
