Explicit weighted consensus horizontal gene transfer networks inferred for the Archaebacteria dataset. A) species tree obtained by Matte-Tailliez et al. ; B) network obtained from full-length sequences using all the nine gene trees from Figure 8 (which were inferred using the ML, NJ, MP and BT approaches) and depicting complete horizontal gene transfer events; C) network obtained by the sliding window procedure with a ML method used for tree inference and depicting complete and partial horizontal gene transfers; D) network obtained by the sliding window procedure with a Bayesian method used for tree inference and depicting complete and partial horizontal gene transfers. The sequence interval corresponding to each partial horizontal gene transfer (see parts C and D of the figure) is given between brackets. The transfer number corresponds to its order of appearance in the gene transfer scenario found by our method. The bootstrap scores of internal branches of the species (backbone) tree and the weights of horizontal gene transfers are also indicated.
