Figure 5

Bayesian consensus tree from spidroin N- and C-termini reconstructing structural motifs and gene duplications. 50% majority-rule consensus of post-burnin Bayesian trees from combined spidroin N+C terminal domains. Numbers above branches indicate PP values; thickened branches supported > 0.95 PP in Bayesian nucleotide analysis (Additional file 5b). Circles at nodes show inferred gene duplication events. Shown below branches are terminal domain amino acid synapomorphies by position (N-terminal positions from 1-168; C-terminal positions from 169-277). Gain of motif along a branch indicated as symbol in legend, and loss by an "X" of the same color. There are other equally parsimonious reconstructions for the evolution of (GA)n and (GGX)n motifs to those shown.
