Fig. 4. Phylogenetic analysis of the TRP gene family. The phylogenetic tree was constructed using neighbour-joining algorithms with bootstrap analysis of 100 pseudo-datasets for node support. Scale bar represents replacement of 5% of the amino acid in the protein alignment. See Table 3 for description of genes used in this tree; c, chicken; cf, crayfish; f, Fugu; h, human; m, mouse; rt, rainbow trout; x, Xenopus; z, zebrafish.
