Abstract

During surveys conducted in dahlia plants in Japan, 2 viroids belonging to the family Pospiviroidae, Potato spindle tuber viroid (PSTVd) and Dahlia latent viroid (DLVd), were identified using various genetic and pathogenicity analyses. This is thought to be the first report of DLVd infecting commercial dahlia in Japan and also of the mixed-infection of DLVd and PSTVd in commercial dahlia plants.
