Effect of age and top removal on alkaloid biosynthesis of Catharanthus roseus roots

, : Effect of age and top removal on alkaloid biosynthesis of Catharanthus roseus roots. Acta Horticulturae (188): 207-214

The plants were sampled at monthly intervals (11 dates) starting 60 days after transplanting. The content of ajmalicine and serpentine varied considerably with age. Root yield, and the percentages of total alkaloid and of ajmalicine increased progressively up to 210 days. The accumulation of serpentine continued with age reaching a maximum in 330-day-old plants.

The Catharanthus roseus plant is the source of many valuable terpenoid indole alkaloids (TIAs), including the anticancer compounds vinblastine and vincristine. Transcription factors (TFs) are promising metabolic engineering targets due to their ab...
