Two secondary metabolic pathways in A. mongolicus. A) Enzymes involved in the pathway of isoflavonoid biosynthesis. B) Enzymes involved in the putative pathway of triterpenoid biosynthesis. Blue boxes indicate the highly expressed enzymes in root and stem, while green boxes indicate the highly expressed in leaf. Red boxes indicate important compounds in the pathway. C) Structural formulas of compounds synthesized in the putative downstream pathway of astragalosides biosynthesis.
