Analysis of a Methanogen and an Actinobacterium Dominating the Thermophilic Microbial Community of an Electromethanogenic Biocathode

Figure 4

Heatmap and hierarchical clustering of the differentially expressed genes of the Methanothermobacter sp. strain EMTCatA1. The scale of the heatmaps was the average of the TMM-normalized count values transformed so that the mean was 0 and the standard deviation was 1 (-score). The assigned clusters were indicated at the rightmost column, with the number of genes contained in each cluster shown in brackets. The red arrowheads indicate the stress-related genes.
