Figure 4

Heat map representing 2026 regulated genes. Only those genes are displayed that are covered by reads in all of the conditions sequenced on the SOLiD system. Genes are clustered for similar regulation patterns among the conditions (vertical columns). Each horizontal column represents a different condition. On the right a similarity tree for the conditions is shown. The heat map was calculated on the relative differences (logFCs) in transcription levels to the reference condition LB. Transcription values higher than in LB are shown in shades of blue, transcription values lower are shown in shades of red. LB, lysogeny broth; pH9, LB-pH9; nitrite, LB-nitrite; spinach, spinach medium; radish, radish shoots; MM, minimal medium; antib, LB-antibiotics; solid, LB-solid; pH4, LB-pH4; faeces, cattle feces; 15°C, LB-15°C.
