Fig. 4.

Summary of the evolution of TRPS channels. The TRPS family is largely restricted to protostome lineages. Figure derived from reconciled maximum likelihood tree of TRPS sequences (supplementary fig. S5, Supplementary Material online). Red dots and colored branches indicate phylum-specific duplication events. Gray and dashed branches indicate that no TRPS sequences were found for the indicated phylum and were inferred to be loss events.
