Comparison between our supertree (left) and the NCBI Taxonomy reference tree (right): This example section of the supertree corresponds to taxa mostly from Rhodospirillaceae with the exception of rogue taxa indicated with a red asterisk. This section is related to the NCBI taxonomy reference tree on the right, containing those Rhodospirillaceae species leaves included in the supertree analysis (27). Nine taxa out of the 27 Rhodospirillaceae included were reconstructed elsewhere in our supertree (not shown). This is representative of the phylogenetic placement errors found throughout the supertree: individual rogue taxa, as well as misplaced clades of related taxa.
