Fig. 6: Circle diagrams showing KEGG enrichment analysis of DEGs.

DEGs under drought stress (A) and salt stress (B). From outside to inside, the first circle represents the KO (KEGG ORTHOLOGY) pathway annotated, the second circle represents the number of genes annotated in this pathway, the third circle signifies the number of up- or downregulated genes, and the fourth circle represents rich factor (0–1).
