Fig. 5From: Morphological, physiological, and transcriptional responses to low nitrogen stress in Populus deltoides Marsh. clones with contrasting nitrogen use efficiencyResults of the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of the special and common differentially expressed genes (DEGs) between genotypes A and C during the response to low N stress. A-special and C-special represent the specific DEGs in genotypes A and C, respectively. AC-common indicates the common DEGs in genotypes A and CBack to article page
