Summary of the differentially expressed genes among the four comparison groups. a Hierarchical heatmap showing the transformed expressional values for the transcripts. Red indicates upregulation and blue downregulation; b Differentially expressed genes statistics in the four comparison groups; c Venn diagrams for upregulated differentially expressed genes in the four comparison groups; and d Venn diagrams for downregulated differentially expressed genes in the four comparison groups
