Annotated Sequence Record


A potyvirus (isolate PFV-FJ) infecting passion fruit in China was identified by small-RNA sequencing. The complete genome sequence of PFV-FJ was determined to be 9974 nucleotides, excluding the poly(A) tail. PFV-FJ shares 70–72% nucleotide and 69–74% amino acid sequence identity at the polyprotein level with seven reported potyviruses, but 89% nucleotide and 91% amino acid sequence identity with an unreported potyvirus, tentatively named “passionfruit Vietnam potyvirus” (PVNV-DakNong). This suggests that PFV-FJ and PVNV-DakNong should belong to the same potyvirus species and that PFV-FJ is a new member of the genus Potyvirus. This new potyvirus was tentatively named “passion fruit severe mottle-associated virus”.
