Phylogenetic tree showing evolutionary relationship of the ICEs harbored by the Vibrio spp. isolated from aquatic products and environment in the Yangze River Estuary, China. Based on the int gene sequences derived from the ICEs characterized in this study and from some known SXT/R391 and Tn916 ICEs in the public databases, the neighbor-joining phylogenetic tree was constructed by using the MEGA 4.0. The accession numbers in the GenBank database of the ICEs displayed in the phylogenetic tree are as following: SXT: AY055428; R391: AY090559; ICEVchind4: GQ463141; ICEPdaSpa1: AJ870986; ICEVflInd1: GQ463144; SXTLAOS: AB114188; ICEVchMex1: GQ463143; ICESpuPO1: CP000503; ICEVchBan9: CP001485; ICEPalBan1: GQ463139; ICEVchBan5: GQ463140; ICEVchInd5: GQ463142; ICEPmiUsa1: AM942759; ICEVchMoz10: NZ_ACHZ01000012.1 and Tn916: EF432727.1. Bootstrap percentages are shown at nodes. The scale bar represents 0.1 changes per amino acid. R and S represent R and S exclusion groups, respectively. ND: not detected.
