All three N-responsive gene classes rapidly respond to a change in N-dose. a Rice seedlings were treated with a N-dose for 120 min (see Methods). During this period, we monitored shoot gene expression responses and shoot N-uptake (via 15N labeling). 15N-uptake significantly correlated with the total number of differentially expressed N-response genes (Pearson R = 0.86, p = 2.8 × 10−3). The table shows that the number of genes found in N, N/W, and N×W classes that were upregulated by N within our factorial N-by-W matrix experiment intersect significantly with the number of genes upregulated in response to a change in N-dose in the time-course experiment (Monte Carlo, adj. p < 0.05). b The same analysis as in a was performed in root tissue (Pearson R = 0.84, p = 4.3×10−3). Overlaps of downregulated N-response genes are presented in Supplementary Fig. 4. Figure 3 source data are provided in Source Data file
