Weighted Gene Correlation Network Analysis (WGCNA) of Arabidopsis Somatic Embryogenesis (SE) and Identification of Key Gene Modules to Uncover SE-Associated Hub Genes

Figure 1

Hierarchical clustering of somatic embryo transcriptomes based on their Euclidean distance using average linkage clustering (replicates of each stage are labeled as “a” and “b”). (a) Unrooted hierarchical clustering dendrogram (the length between nodes corresponds to the distance between samples). (b) Hierarchical clustering heatmap visualizing the correlations between the samples.
