Fig. 5From: Transcriptome of the synganglion in the tick Ixodes ricinus and evolution of the cys-loop ligand-gated ion channel family in ticksMaximum-likelihood phylogenetic tree of cys-loop LGICs, excluding nAChRs. The phylogeny includes sequences from the tick I. ricinus and representative arthropods: P. tepidariorum (house spider), Acariformes, Parasitiformes, and D. melanogaster. Labels indicate accession numbers of protein sequences and abbreviated species name (abbreviations as in Fig. 4, plus Gocci for Galendromus occidentalis). Labels for I. ricinus sequence are in blue. Filled circles on branches indicates bootstrap support (support increases with circle width, ranging from 80 to 100)Back to article page
