Expression patterns of P. sibiricum DEGs during seed dormancy release and seedling establishment. A Hierarchical clustering of all DEGs. Red and blue represent increased and decreased transcript abundances, respectively. The eight main subclusters are indicated at the branching points (left side). B Results of the K-medoids clustering. The Z-scores of log2 (FPKM+ 1) were used for the K-medoids clustering with the MEV software (v. 4.9.0) and Pearson correlations. The subcluster number is provided in the upper right corner of each subgraph. The numbers in dark blue indicate the number of DEGs in each subcluster. The numbers of DEGs in the Corm vs Seed, Str_S vs Corm, and Eme vs Corm comparisons are summarized (top to bottom) under the expression curves for each subcluster. Red and green numbers represent the number of transcripts with increased and decreased abundances, respectively
