Phylogeny of teleost-specific tlr s. Unrooted phylogenetic tree of teleost-specific tlrs – tlr21, tlr22 and tlr23. Numbers at the nodes indicate posterior probability values from Bayesian inference. Posterior probability values were calculated for each node by Bayesian analysis based on 250,000 generations. Samples were collected every 100 generation and a consensus tree was built after burning the initial 1,250 trees. Only probability values above 0.8 are indicated: 0.95 to 1 shaded in red, 0.9 to 0.94 in blue and 0.8 to 0.89 in green, respectively. Atlantic cod genes are highlighted within red boxes.
