Comparative transcriptomics of the PL and the cht7 mutant. A and B, Global gene expression analysis of the PL and cht7 following N resupply. Blue circles: total number of genes changed in expression in a comparison of PL after 48 h of N deprivation followed by 6 h (A) or 12 h (B) of N resupply over PL N-deprived for 48 h. Yellow circles: total number of genes changed in expression in a comparison of PL NR6 over cht7 NR6 (A) or PL NR12 over cht7 NR12 (B). NR6 and NR12, 6 and 12 h of N resupply, respectively. C, Heat map of the overrepresented MapMan categories in the overlapping gene groups as depicted in A and B. The first column has the bin code of the categories and the second column lists the explanation of each category. The color in the heat map represents the -log10 of the q-value obtained from Fishers exact test ranging from 1.3 to 10 (0.05–1E-10). The number of genes in each gene group is given in parentheses near the gene group name in the legend of the heat map.
