A Catharanthus roseus mutant accumulates high levels of ajmalicine at the expense of catharanthine and vindoline. The altered chemistry depends on increased expression and biochemical activities of strictosidine β-glucosidase and ajmalicine synthase activities and reduced expression and
The important anticancer drugs, vinblastine, vincristine and analogs, are composed of the monoterpenoid indole alkaloids (MIAs), catharanthine and vindoline, found uniquely in the medicinal plant, Catharanthus roseus. While 26 genes involved in the assembly of these two MIAs are known, two key
Antihypertensive compound ajmalicine and antileukemic vincristine and vinblastine are three important terpenoid indole alkaloids produced by Catharanthus roseus (Apocynaceae). This study has been done to investigate the effects of methyl jasmonate (100 μM) and silver nitrate (50 and 100 μM)
To compare the effects of different carbon sources on physiological aspects, especially medicinal alkaloid biosynthesis and related gene expression in Catharantus roseus (L.) G.Don, we employed sucrose and sorbitol with two concentrations (87.64 mM, the equimolar concentration of sucrose in MS basal
Monoterpene indole alkaloids (MIAs) are specialized metabolites synthesized in many plants of the Apocynaceae family including Catharanthus roseus and Rauvolfia sp. MIAs are part of the chemical arsenal that plants evolved to face pet and herbivore attacks, and their high biological activities also
