Starch biosynthetic pathway adapted from Bahaji et al. 2014. Metabolites are shown in black, and enzymes are shown in green. Shown are TMM-normalized FPKM values for homologs in all four species (bata = Ipomoea batatas, trif = I. trifida, diss = Distimake dissectus, and quin = D. quinquefolius). Grey boxes indicate genes where orthology could not be determined. Stacked boxes indicate homologs of a particular gene. Gene names with an asterisk were found to be significantly differentially expressed at a FDR < 0.05 in both I. batatas and D. dissectus. The heatmap is colored by percentile, where genes in the 10th percentile were colored yellow and those in the 90th percentile were colored dark blue
