AI Article Synopsis
- - A new potyvirus named "paris virus 1" (ParV1) was discovered in Paris polyphylla var. yunnanensis, with its complete genome sequence published in GenBank.
- - The genome features a single large open reading frame that encodes a polyprotein of 3240 amino acids, which is predicted to be cleaved into 10 functional proteins, showing typical potyvirus structures.
- - Comparisons with other potyviruses reveal that ParV1 shares a significant portion of its genetic material with related viruses, particularly Thunberg fritillary mosaic virus, suggesting that it is a distinct member of the potyvirus genus.
Article Abstract
The complete genome sequence of a novel potyvirus, tentatively named "paris virus 1" (ParV1, GenBank accession no. MN549985), infecting Paris polyphylla var. yunnanensis was determined in this study. A single large open reading frame (nt 96-9818) encoding a 3240-aa polyprotein that is predicted to be cleaved into 10 mature proteins was detected in the ParV1 genome. Comparative analysis of the ParV1 genome sequence with those of other potyviruses identified nine cleavage sites and conserved motifs that are typical features of potyviruses. Pairwise sequence comparisons showed that the ParV1 polyprotein shares 49.6-65.1% nucleotide and 47.1-68.9% amino acid sequence identity with viruses of the genus Potyvirus. BLAST analysis revealed that ParV1 shares 65.1% nucleotide and 68.9% amino acid sequence identity with Thunberg fritillary mosaic virus (TFMV, accession no. CAI59123), its closest known relative. These results suggest that paris virus 1 (ParV1) is a new member of the genus Potyvirus.
