Transcript induction under LowP is repressed by LowN. a Reaction norm plot of differential transcript accumulation (log2 fold change, LFC) for 444 genes induced by lowP in the leaf with respect to Full (green) under LowN (red), LowP (yellow) and combined LowNP (blue). Numbers indicate the count of genes above/below the +/− 1 LFC threshold. b Heat map showing the mean LFC in each treatment of genes associated with selected GO terms enriched in the 1555 gene set (Supplemental File 2). LFC calculated with respect to Full, separately for roots and leaves. GO term names are abbreviated. GO term identifiers are given in parentheses along with the number of genes assigned in the test set over the total number in the GO term. The significance of GO term enrichment is indicated to the left of the heat map as *** p < 0.001, ** p < 0.01, * p < 0.05
