Figure 2From: Evolution of a cluster of innate immune genes (β-defensins) along the ancestral lines of chicken and zebra finchBayesian major consensus tree of the relationship between AvBD genes found in the chicken and zebra finch genome. Genes in blue ending with z denote lineages found in the zebra finch genome and genes marked in red and a c-suffix denotes genes found in the chicken genome. Posterior probabilities are displayed at the branches and corresponding bootstrap values above 50 obtained from neighbour-joining method is displayed in brackets). Highlighted Cluster A and B refer to two clusters of duplicated genes, presumably originating from the genes AvBD1 and 3 (see arrows). Genes with identical signal peptides are noted with similar triangles to the right of the sequence name. The tree is calculated as unrooted and then rooted on mid-point.Back to article page
