Figure 1From: PSAT: A web tool to compare genomic neighborhoods of multiple prokaryotic genomesEvidence of gene orthology through sequence homology and gene order conservation. The Francisella tularensis subspecies novicida U112 gene FTN_0453 does not have any homologous genes in other Francisella strains. The PSAT genomic neighborhood browser, however, highlighted a gene cluster between F t novicida U112 and genomes from genera such as Shewanella and Vibrio. The conserved order of the homologs provided secondary evidence that the genes in this cluster are orthologs.Back to article page
