Abstract
The plant-pathogenic fungus Exobasidium gracile belongs to the basidiomycetous genus Exobasidium and causes leaf abnormalities in Camellia oleifera. Here, we report a novel mycovirus from E. gracile strain Z-2, called "Exobasidium gracile zybavirus 2" (EgZV2), which is related phylogenetically to a member of the genus Zybavirus in the family Amalgaviridae. Like those of other zybaviruses, the EgZV2 genome has two large open reading frames (ORFs) encoding an unknown protein and an RNA-dependent RNA polymerase (RdRp), respectively. In addition, we found a conserved +1 programmed ribosomal frameshifting (PRF) motif (UUUCGG) between ORF1 and ORF2 in EgZV2.
