Protopanaxadiol (PPD) is an aglycone of dammarene-type ginsenoside and has high medicinal values. In this work, we reported the PPD production in transgenic tobacco co-overexpressing PgDDS and CYP716A47. PPD is an aglycone of ginsenosides produced by Panax species and has a wide range of pharmacological activities. PPD is synthesized via the hydroxylation(More)
BACKGROUND The roots of Panax ginseng contain noble tetracyclic triterpenoid saponins derived from dammarenediol-II. Dammarene-type ginsenosides are classified into the protopanaxadiol (PPD) and protopanaxatriol (PPT) groups based on their triterpene aglycone structures. Two cytochrome P450 (CYP) genes (CYP716A47 and CYP716A53v2) are critical for the(More)
