Volcanogram (a represents root, b represents shoot), cluster map (c indicates shoot, d indicates root), e number of differentially expressed genes in wheat, and f Venn map under nitrogen-deficient condition. R_0 and L_0 represent the root and shoot of N0 (nutrition solution without nitrogen) group of plants, respectively; R_1 and L_1 represent the root and shoot of N1 (complete nutrition solution) group of plants, respectively. In volcanogram (a, b), gray points were the genes with a non-significant difference, red and green points were the genes with significant differences; X-axis display of log2 foldchange (FC), and Y-axis display p-value. In the cluster map (c, d), red represent up-regulated and blue represent down-regulated protein-coding genes
