Fig. 5From: Tissue-specific transcriptome analyses reveal candidate genes for stilbene, flavonoid and anthraquinone biosynthesis in the medicinal plant Polygonum cuspidatumScatterplot of differentially expressed Polygonum cuspidatum genes in the top 20 enriched KEGG pathways. a Leaf vs Stem, b Leaf vs Root, and c Stem vs Root. The y-axis shows the KEGG pathways, and the x-axis shows the enrichment factor. The enrichment factor is the ratio of the numbers of DEGs annotated in a certain pathway to the total number of genes mapped to this pathway. The q-value represents the corrected P value. A higher enrichment factor value correlates with a more intensive pathway, and a lower q-value with a more reliable oneBack to article page
