Hierarchical Clustering Analysis (HCA) of the differentially phosphorylated proteins during SE. Cluster identification and number of profiles included in each cluster are indicated on the left. The color of the line indicates the affiliation of the protein to the current class. For the heat map, the x-axis represents the samples, the y-axis represents the different phosphoproteins, and the color indicates the relative abundance of each protein in the sample. The top 2 most significantly enriched items from the GO and KEGG enrichment analyses are shown to the right of the corresponding cluster enrichment pattern clustering graph. GO_CC, cellular component; GO_BF, biological process; GO_MF, molecular function
