Abstract:
The complete genome sequence of a virus from lily (Lilium lancifolium Thunb.) growing in Huoshan County, Anhui Province, China, was determined. The whole genome consists of 9558 nucleotides, excluding the poly(A) tail, and encodes a 3061-amino-acid polyprotein (GenBank number ON365558) typical of potyviruses. This is the first complete genome sequence of iris potyvirus B (IPB), for which only a partial sequence from Iris domestica was reported previously. Comparative analysis of this genome sequence with those of closely related potyviruses identified nine cleavage sites and the conserved motifs typical of potyviruses. The complete polyprotein ORF shares 73.6% nucleotide and 81.6% amino acid sequence identity with that of iris potyvirus A (IPA, GenBank number MH898493). Phylogenetic analysis showed that IPB is related to IPA and clusters in a group with lily yellow mosaic virus (LYMV). This is the first report of IPB infecting lily plants.
