Figure 6

Hierarchical clustering of the differentially expressed genes identified in the four comparisons. The four columns of the cluster report in red and green the genes up and down-regulated in the four comparisons considered: (1) DB110 strain grown at low pressure vs. DB110 grown at high pressure (in red genes up-regulated at low pressure, in green those more expressed at high pressure); (2) TW30 strain grown at high pressure vs. DB110 strain grown at high pressure; (3) TW30 grown at low pressure vs. DB110 grown at low pressure; (4) TW30 grown at low pressure vs. TW30 grown at high pressure. Some gene clusters are highlighted in colour and a general description of the role of the genes is reported. The expression profile behaviour of the genes belonging to each cluster is visualized also in the right part of the figure using a different visualization.
