Bayesian phylogenetic analysis of Toll genes from insects and crustaceans, with C. elegans as an outgroup. All Toll genes thought to be involved in the immune system are highlighted in bold text. Genes marked with * need further in vivo experiments to prove their role in immunity. Branch numbers are posterior probabilities.
