Fig. 6From: Duplication and concerted evolution of MiSp-encoding genes underlie the material properties of minor ampullate silks of cobweb weaving spidersBayesian tree for combined N- and C-terminal spidroin-encoding nucleotide sequences. See Table 1 for accessions. Bold branches are supported by > 50% bootstrap parsimony and > 95% posterior probability in all analyses of combined N- and C-terminal sequences (see Additional file 1: Figure S7). Asterisks (*) indicate > 95% posterior probability in Bayesian analyses of N- and C-terminal sequences. Units are substitutions per site. The tree is rooted with Bc fibroin1. Duplications inferred by reconciliation with the species trees in Fig. 1 are shown as red dots at nodes. The red dots with yellow outlines indicate that concerted evolution of terminal encoding regions could also explain the observed relationshipsBack to article page
