Fig. 4: Gene expression in BIA metabolism pathways.

The four numbers in parentheses indicate gene copy numbers in Papaver somniferum (Pso), Macleaya cordata (Mco), Aquilegia coerulea (Aco), and Nelumbo nucifera (Nnu). The heatmaps represent the gene expression level in two different Pso samples (HN1 and CHM). In each heatmap, the columns from left to right represent stem (stem of HN1, one day after the onset of anthesis), stem_5days (stem of HN1, five days after the onset of anthesis), stem_c (stem of CHM in fructescence), stem_cz (stem of CHM in the growth period), stem_gc (stem of CHM in early fruit development), and stem_gz (stem of CHM in the metaphase of fruit development)
