C. Metabolite profile following three cycles of rapamycin and glucosamine treatment. The abundance of isoprenoid biosynthestic intermediates (1-deoxy-xylulose-5-P (DOXP), methyl-erithritol-4-P (MEP), methyl-erithritol-cyclo-2,4-PP (MEcPP), and isopentyl-PP), and hemoglobin-like peptides are presented as the mean log2 fold change from four biological replicates (±SD).
