Genome organization and phylogenetic relationship of Pineapple mealybug wilt associated virus-3 with family Closteroviridae members.
The nucleotide sequence of Pineapple mealybug wilt associated virus-3 (PMWaV-3) (Closteroviridae: Ampelovirus), spanning seven open reading frames (ORFs) and the untranslatable region of the 3' end was determined. Based on the amino acid identities with orthologous ORFs of PMWaV-1 (54%-73%) and PMWaV-2 (13%-35%), we propose PMWaV-3 is a new species in the PMWaV complex. PMWaV-3 lacks an intergenic region between ORF1b and ORF2, encodes a relatively small, 28.8 kDa, coat protein, and lacks a coat protein duplicate. Phylogenetic analyses were used to analyze seven different domains and ORFs from members of the family Closteroviridae. Two distinct clades within the recognized genus Ampelovirus were observed; one that includes PMWaV-3 and PMWaV-1 and several GLRaVs and another that includes PMWaV-2 and GLRaV-3, the type member of the genus Ampelovirus.
