Figure 1

Similarity plot for unique recombination events (a–e) detected using RDP4 and phylogenetic reconstruction. The query sequence name (recombinant) is indicated at the top of each panel. The x axis indicates the nucleotide position (ORF) of the query sequence at the center of the sliding window (k). The y axis indicates the similarity, s(k), between the corresponding window of the query sequence and each of the reference sequences. A non-recombinant reference sequence from a given lineage was used to represent the relationship between the query (recombinant) sequence and each lineage. The colored bar at the top of each plot indicates the ‘best match’, which is the reference sequence with the highest identity to the query sequence. The specific reference sequence and lineages of the viruses contributing to the recombinant virus are indicated in the legend.
