Venomics of cottonmouth subspecies. The venom proteins of A. p. conanti, Florida cottonmouth, (panel A); A. p. leucostoma, western cottonmouth, (panel B); and A. p. piscivorus, eastern cottonmouth, (panel C) were fractionated and analyzed as described in the legend of Fig. 2. The results are listed in Supplementary Tables S8–S10. Panels D–F display pie charts showing the relative occurrence of proteins from different toxin families in the venoms of cottonmouths fractionated in panels A–C, respectively.
