Complete nucleotide sequence of chrysanthemum virus D, a polero-like virus

AbstractA putative new polerovirus, named “chrysanthemum virus D” (ChVD), was detected in aChrysanthemum morifolium plant in South Korea. The virus was identified by high-throughput sequencing and confirmed by reverse transcription polymerase chain reaction. The entire ChVD genome is composed of 5,963 nucleotides and contains seven open reading frames (ORF0-5 and ORF3a), which are arranged similarly to those of other poleroviruses. These ORFs encode the putative proteins P0-5 and P3a, respectively. Pairwise amino acid sequence comparisons showed that the ChVD P0-5 and P3a proteins have 30.45 –75% sequence identity to the corresponding proteins of other members of the genusPolerovirus. Since one of the species demarcation criteria for the genusPolerovirus is>  10% difference in the amino acid sequence of any gene product, the sequence comparisons indicate that ChVD represents a new species in this genus. Phylogenetic analysis of the P1-P2 and P3 amino acid sequences further indicate that ChVD is a novel polerovirus.
