KEGG pathway enrichment analysis. a-c Functional classification of DEUs in KEGG term “organismal systems” from s-H vs c-H (a), s-F vs c-F (b) and s-A⁺ vs c-A⁺ (c). The ID and percentage of each KEGG term are indicated in the pie chart. d-i Top 30 enriched KEGG pathways of specifically up- or down-regulated DEUs from s-H vs c-H, s-F vs c-F and s-A⁺ vs c-A⁺, respectively. The x-axis indicates the rich factor of each pathway and y-axis shows pathway. The color and size of dot indicates Q value and the number of DEUs assigned to the corresponding pathway respectively
