Figure 7. Hierarchical clustering of DEGs.

Figure 7

(A) Heatmap plot of DEGs using the hierarchical clustering method; eight main clusters are shown; expression values of six individual germination stages are presented after being centered and log-transformed; decreased (blue) and increased (red) expression of DEGs are distinguished from different species and stages; (B) Expression patterns of genes in the eight main clusters, namely K1-K8, corresponding to the hierarchical heatmap.
