Diagram of differential gene expression analysis. A Heatmap of DEGs. The horizontal coordinates indicate the sample clusters. The more identical genetic expression levels between specimens, the closer they are in the graph. The color scale denotes the richness of genetic expression. The yellow color denotes upregulation and the red color indicates downregulation. B Volcanic map. The red dots indicate downregulated DEGs; the blue dots indicate upregulated DEGs; the gray dots indicate genes with no differential expression
