Figure 1From: Genome wide evolutionary analyses reveal serotype specific patterns of positive selection in selected Salmonella serotypesExample of neighbor joining tree used for positive selection analysis. Gene specific trees were used for all positive selection analysis. The tree showed here represented the phylogeny of 849 genes. Branches used for branch specific analyses are indicated; Ch# = Choleraesuis branch specific test; Ty# = Typhi branch specific test; Tym# = Typhimurium branch specific test; Pty# = Paratyphi A branch specific test.Back to article page
