Relationship dendrogram constructed from sequence distance data.
The relationship dendrogram was constructed using TreeView, from output from the neighbour-joining option in DNAMAN 3.0, calculated from pairwise nucleotide sequence distances derived from the alignment shown in Figure 1. Horizontal scale indicates sequence divergence, vertical scale is arbitrary. The dataset was subjected to 1000 bootstrap replicates: only nodes supported by >80% scores are shown, all others were collapsed to form polytomies. Sequences derived in this work are italicised.
