Abstract
A unique circular molecule of 358 nucleotides was detected in American persimmon (Diospyros virginiana L.). The molecule was graft-transmissible and had genetic characteristics of members of the genus Apscaviroid. It had the highest sequence similarity (72-73 %) to citrus viroid VI (CVd-VI) and formed a clade with CVd-VI, citrus dwarfing viroid, and apple dimple fruit viroid in a phylogenetic tree. The molecule was not detected in citrus, unlike CVd-VI, which infects citrus and persimmon, and it was genetically distant from persimmon latent viroid, which infects persimmon only. The genetic and biological features indicated that the molecule may be a member of a new apscaviroid species.
