KEGG enrichment of DEGs in willow under Co treatment. Top 20 enriched pathways from Tops (a) and Roots (b) are presented, respectively. Rich factor indicated the ratio of enriched DEGs number to the total number of genes have been annotated in this pathway. The numbers of DEGs enriched in each pathway are indicated by circle size. The enrichment scores (−Log10 (Q value)) of each KEGG pathways are shown by color gradient.
