Fig. 1. Distribution of pairwise L1 nucleotide sequence comparisons of 189 Papillomaviruses.

Fig. 1

L1 nucleotide global multiple sequence alignments were guided by amino acid alignment using MUSCLE v3.7 (Edgar, 2004) and Seaview v4.1 (Galtier et al., 1996) software. A matrix of 189 L1 regions compared to each other, resulted in a total of 17766 percent identity values. Gaps were included and counted as one position. The Y-axis represents the percent of the total number of comparisons. The X-axis shows the L1 nucleotide sequence percent identity. The figure has a predominantly bimodal distribution with overlap at around 60% nucleotide sequence identity.
