Volcano plot and heatmap analysis of differentially expressed circRNAs after FMDV infection. (A) The red, green, and gray dots represent upregulated, downregulated, and not significantly regulated circRNAs respectively. The x-axis indicates the fold-changes of differentially expressed circRNAs; the greater the absolute x-value, the greater the fold change. The y-axis represents the significance of the differentially expressed circRNAs; the greater the y-value, the smaller the p value. (B) Red indicates higher expression and green indicates lower expression. Each row represents a circRNA parental gene, each column represents a sample, and the tree diagram of the gene cluster is to the left.
