Scatterplot of the 30 most enriched KEGG pathways of the differentially expressed (DE) circRNAs. The 30 most enriched KEGG pathways at 6, 10, and 14 days post infection (DPI) and at SI (secondary infection, 30 DPI). The y-axis represents the distinct KEGG pathways, while the x-axis represents the rich factor. The rich factor refers to the ratio of DE circRNAs annotated in the pathway to the total number of genes annotated in the pathway. The higher the rich factor, the greater the degree of pathway enrichment. The size of dots represents the number of DE circRNAs, with larger dots denoting a large number of DE circRNAs. The colours of the dots represent the p-values of enrichment
