Figure 2From: The society of genes: networks of functional links between genes from comparative genomicsThe combined network in H. pylori. The networks of the three individual methods (shown in Figure 1) are superimposed. Links colored yellow were obtained by phylogenetic profiling; links colored blue by conserved chromosomal proximity, and links colored red by domain fusion. The remaining links are coded as composites of the three primary colors: purple, links found by both fusion and chromosomal proximity; green, links found by chromosomal proximity and phylogenetic profiling, orange, links found by phylogenetic profiling and fusion; and brown, links found by all three methods. The nodes highlighted in red and blue identify genes that participate in oxidative phosphorylation and aromatic amino-acid biosynthesis, respectively (see Figure 4).Back to article page
