Abstract:
We report the complete nucleotide sequence of a new member of the Potyviridae family isolated from passion fruit plants grown in Israel, called Passiflora edulis symptomless virus (PeSV). The PeSV genome is 9,928 nucleotides long and encodes a 3,173 amino acids polyprotein that is predicted to be proteolytically cleaved into 10 mature peptides. Our phylogenetic analysis shows that PeSV represents a new species, and is most closely related to rose yellow mosaic virus (RoYMV). According to currently accepted criteria for genus demarcation, both viruses should be assigned as representative isolates of new species in the recently approved genus, Roymovirus, in the Potyviridae family.
