An overview of the maize GGM network. a A histogram showing the distribution of the partial correlation coefficients of all the gene pairs. Most genes pairs have their Pcors in the range between −0.01 and 0.01, indicating no interactions. b A sub-network for the largest 25 modules identified from the network. Each dot represents a gene, and a connection between two genes indicates interaction between the two. The color of a node indicates its module identity, as shown in the legend
