EPMs identified in the heat shock condition. (a) The result by hierarchical clustering of the average expression patterns of EPMs in the heat shock condition. The numbers indicate the EPM indices. (b) Regulator matrix whose entries represent the percentage of genes controlled by each transcription factor in the EPM. The names of transcription factors are shown on the left side. (c) Gene annotation enrichment matrix whose entries represent the enrichment levels of each EPM in the GO 'biological process' categories shown on the left side. For efficient explanation and visualization, only selected GO categories are shown. EPMs identified in the nitrogen depletion and the cell cycle conditions are shown in Additional data file 2.
