Schematic presentation of the putative recombination regions in the 3' end half of the genomes of the pepper-infecting poleroviruses <i>Pepper yellow leaf curl virus</i> (PYLCV) and <i>Pepper vein yellowing virus</i> (PeVYV).

<p>(<b>A1</b>) The 3' part of the PYLCV genome, including its adjacent ORFs. (<b>A2</b>) A scheme describing the distribution of nucleotide sequences in PYLCV genome, which illustrates the high level of similarity of the PYLCV sequences with sequences found in the homologous ORFs of the two poleroviruses <i>Tobacco vein-distorting virus</i> (TVDV) and <i>Cucurbit aphid-borne yellows virus</i> (CABYV). (<b>A3</b>) A scheme describing the distribution of nucleotide sequences in the PeVYV genome that are very similar to sequences found in the homologous locations in the genomes of TVDV, CABYV and <i>Potato leaf roll virus</i> (PLRV). The putative recombination regions were identified by BLAST search analysis. The solid arrows indicate the positions of the putative recombination sites in ORF3, ORF4, ORF5 and the 3' NCRs of PYLCV and PeVYV.
