RESUMEN
The complete genome sequence of a new polerovirus found naturally infecting Artemisia princeps, artemisia virus B (ArtVB), was determined using high-throughput sequencing. The ArtVB genome comprises 6,141 nucleotides and contains six putative open reading frames (ORF0 to ORF5) with a genome structure typical of poleroviruses. A multiple sequence alignment showed that the complete ArtVB genome shares 50.98% nucleotide sequence identity with ixeridium yellow mottle virus 1 (IxYMaV-1, GenBank accession no. KT868949). ArtVB shares the highest amino acid sequence identity in P0 and P3-P5 (21.54%-51.69%) with other known poleroviruses. Phylogenetic analysis indicated that ArtVB should be considered a member of a new species within the genus Polerovirus, family Luteoviridae.
