Figure 2. A global view of transcriptome/transcriptome comparisons for each organism.

Each point is the mean (across replicates) log2 RPKM for one condition vs. another, as indicated. Colored circles highlight some of the differentially expressed modules. Pilus, the unique Type II secretion module; Xox, the Mmol_1769/Mmol_1770 gene pair; Flagellum, flagellum cluster 1; NMGP, genes of N-methylglutamate pathway for methylamine oxidation.
