Changes in NO3- responsiveness for genes in significant N/H biclusters vs. N-bicluster 9 exclusive genes. Histogram plots of average expression over NO3- treatment conditions in both WT and NR double mutant microarray data showing the nitrate responsiveness of genes that were present in significant hormone biclusters and genes that were not present in any N/H-bicluster (N-bicluster 9 exclusive (E)), data indicates root and shoot responses in WT and NR double mutant plants). Comparison between treatment and control across the different groups indicates a clear difference in both the baseline expression level and average response to nitrate for N/H-biclusters 1, 16, 19 and 20 and was confirmed with ANOVA (see text). (+) KNO3 treatment, (-) KCl treatment.
