Phylogenetic tree of the insect TRP channels. Amino acid sequences of channel-forming six transmembrane domains of Drosophila melanogaster (Dm), Bombyx mori (Bm), Tribolium castaneum (Tc), Apis mellifera (Am), Nasonia vitripennis (Nv), and Pediculus humanus (Ph) TRP channels were aligned by the Muscle program, and then PhyML3.0 algorithm was applied for the maximum likelihood analyses, under the WAG amino acid substitution model and with 100 bootstrapped data sets using the PhyML Online server. The statistical confidence (bootstrap value) is indicated next to each interior branch. The insect TRP channels can be classified into 7 subfamilies, TRPC (red), TRPV (green), TRPM (light blue), TRPP (purple), TRPML (blue), TRPN (yellow), and TRPA (brown). The amino acid sequences of the insect TRP channels are listed in an Additional file 2.
