Metabolic Atlas of Physarum polycephalum. All P. polycephalum cDNAs (Refs [5,6] and our results) were sent for KEGG Ortholog  (KO) prediction using the KAAS server . The output list of orthologs was used to plot this atlas with the KEGG mapping tool . Nodes represent metabolites and edges (lines) correspond to enzymatic reactions. Colors are assigned to either down- (light blue) or upregulated (green) transcripts. Transcripts with equivalent relative frequencies in both novel cDNA libraries (relL/relD = 1) are also depicted (yellow); white represent those cDNAs with no expression data. After photoinduction, most enzymes from the N-glycan biosynthesis (A) and the urea cycle (D) pathways are upregulated. In contrast, cDNAs mapped to the oxidative phosphorylation (C) had higher relative frequencies in competent plasmodia, whereas a change from fatty acid synthesis to degradation is seen after photoinduction (B).
