Arachis mottle-associated virus, a new polerovirus infecting pinto peanut

Abstract

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