Resumo
A new polerovirus, named “arachis mottle-associated virus” (ArMoV), was identified by high-throughput sequencing in a Pinto peanut (Arachis pintoi) plant. The genome sequence was confirmed by Sanger sequencing and contains 5775 nucleotides and seven predicted open reading frames (ORFs), showing a typical polerovirus genome structure. All of the proteins encoded by ArMoV showed less than 90% amino acid sequence identity to those of other poleroviruses, the threshold to establish a new species in the genus. Phylogenetic analysis based on P1-P2 fusion protein and coat protein amino acid sequences showed that tobacco polerovirus 1 and chickpea chlorotic stunt virus, respectively, were the most closely related to ArMoV. These data suggest that ArMoV is a member of a new species of the genus Polerovirus, for which the binomial name Polerovirus ARMOV is proposed.
