Fig. 3From: 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 differentially expressed genes (DEGs) in genotype A at different time points and common DEGs in genotypes A and C during the response to low N stress. T0 special, T2 special, T4 special, and T6 special represent the specific DEGs at T0, T2, T4, and T6 in genotype A, respectively. “Common” indicates the common DEGs at T0, T2, T4, and T6 in genotypes A and CBack to article page
