Figure 3From: Predicting gene regulatory networks of soybean nodulation from RNA-Seq transcriptome dataDetermination of number of clusters. The initial cluster number for each group is determined based on the change trend between average correlation coefficient of expression values of genes in the same clusters and average size of clusters (i.e. number of genes in the cluster). The rectangle fields show the drastic change on correlation coefficients and cluster sizes. Here, group 1 represents the DEGs based on the comparison at 12Â hours; group 2 represents the DEGs based on the comparison at 24Â hours; group 3 represents the DEGs based on the comparison at 48Â hours; overlap represents the genes differentially expressed based on the comparisons at all three time points.Back to article page
