DNB members and correlations among these molecules were visualized in molecular networks by using Cytoscape. Node color reflects the standard deviation of the corresponding genes. The strength of correlations is represented by edge width, where a wider edge corresponds to a higher correlation. For clarity, the strength of correlations was also reflected by edge color. a A more reliable co-expression gene regulatory network of the Arabidopsis floral transition. b Three key subnetworks in DNB given separately
