Consomatins and signaling SSRP-like sequences show contrasting evolutionary patterns. (A) Bayesian gene tree of consomatin and nerve ring SSRP-like sequences from diverse cone snail species. Branch lengths are proportional to estimated amino acid change, highlighting the speed with which consomatins have diverged, as compared with the nerve ring sequences. Only posterior probabilities values below 0.95 are depicted for visual clarity. (B) Position-specific evolutionary rates of SSRP-like 1 (top), SSRP-like 2 (middle), and consomatin (bottom) sequences as determined using rate4site. Amino acids of the corresponding sequences from Conus rolani are shown for clarity. Color codes are the same as in fig. 2.
