Podophyllotoxin is the natural product precursor of the chemotherapeutic etoposide, yet only part of its biosynthetic pathway is known. We used transcriptome mining in Podophyllum hexandrum (mayapple) to identify biosynthetic genes in the podophyllotoxin pathway. We selected 29 candidate genes to
Plants contain a large number of proteins homologous to isoflavone reductase, an NADPH-dependent reductase involved in the biosynthesis of isoflavonoid phytoalexins in legumes. Although some are bonafide isoflavone reductases, others may catalyze distinct reductase reactions. Two tobacco genes, TP7
