Members of Vibrionaceae (Gammaproteobacteria: Wnt inhibitor Vibrionales) have been known since 1854 (Pacini) and were shown to be distinct much before pulsed-field gel electrophoresis selleck products revealed the most distinct diagnostic “morphological” feature, the existence of two chromosomes . The interest in these bacteria is not surprising given that several species are pathogenic to humans and marine organisms and others are bioluminescent symbionts of marine fishes and squids e.g.[2–7]. Some lesser-known species are psychrophiles (live in cold temperatures), piezophiles (live at high pressures), or halophiles (live at high NaCl concentration; ). The diversity of ecologies represented by members of Vibrionaceae has led to enthusiastic genome sequencing in the group, which has focused most heavily
on pathogenic species (more than 31 strains of V. cholerae are available on GenBank as of 2012). A phylogenetic hypothesis based on complete genomes was desired for Vibrionaceae. While the analysis presented in  for Vibrionaceae was the most comprehensive to date (eight gene Cediranib (AZD2171) loci for 95 Vibrionaceae species) and provided the a hypothesis for a phylogenetic taxonomy for the group, the number of genomes already sequenced for Vibrionaceae lends itself to a genome-level analysis. While the specter of horizontal gene transfer always looms over phylogenetic analyses of bacteria, genome-level analyses take a proactive stance in the hopes of recognizing and quantifying problematic data partitions without blind dismissal of all phylogenetic signal. Because members of Vibrionaceae have two chromosomes, as discussed below, the genome-level phylogenetic analyses presented here provide phylogenetic evidence for the evolutionary scenarios that have been postulated for the maintenance of these two separate chromosomes. There are also many Vibrionaceae species that are present on GenBank as multiple contigs. This was not the case for members of Shewanellaceae, the sister taxon to Vibrionaceae, for which a genome-level phylogenetic hypothesis was presented in .
