Phylogenetic relationship of zebrafish (Dr) β1 integrin chains with representative deuterostome orthologs. Maximum Likelihood tree is shown with supporting Neighbor Joining bootstrap replicates (black), Maximum Parsimony bootstrap replicates (blue) and Bayesian clade credibility values (brown). Horizontal scale is amino acid replacements per site. Ciona intestinalis β1 (Ci_b1) was used to root the tree; homo sapiens β1 (Hs_b1) is shown as an example of tetrapod sequence.
