Co-occurrence of circadian clock proteins in Cyanobacteria. a The p-values, calculated by pair-wise Fisher’s exact tests, are visualized in a heatmap. Only p-values ≤ 0.01 are considered as significant. Proteins are sorted by a hierarchical agglomerative clustering algorithm. b Network of significant co-occurring circadian clock factors in Cyanobacteria, calculated in regard to the results of the pair-wise Fisher’s exact test. The line color corresponds to the level of significance. Missing links are those that had a higher p-value than 0.01. Node size is proportional to the degree of that node
