Bayesian phylogenetic analysis of scavenger receptor domains (SRCR) from scavenger genes from available arthropod sequences. SRCR copy number varies from 1–3 among the genes analysed. For those genes containing more than one SRCR domain, the gene name has been appended with A, B or C according to the 5' to 3' position of the SRCR domain. Posterior probabilities are indicated at nodes. Genes that have been functionally characterized as members of the immune system repertoire are indicated with bold text.
