Enriched KEGG pathways among DEGs between plants grown in canga and forest substrates. Scatterplots of enriched KEGG pathways in up-regulated (yellow shades) and down-regulated (purple shades) gene groups for P. platycephala (left) and S. pulcherrimum (right). The significantly enriched pathways were indicated as dots (FDR < 0.05), and the dot sizes represent the number of the genes included in each cluster. The x-axis represents the ratio of the number of differentially expressed genes and all genes in the pathway. The deeper the color, the smaller the FDR corrected p-value. Colored letters next to the names of the routes indicate uniquely altered pathways in one species. P in cyan—P. platycephala; S in pink—S. pulcherrimum
