A number of deuterium labelled 9- and/or 10-oxygenated derivatives of geraniol, geranial, nerol, and neral were used as substrates in feeding experiments with a cell suspension culture of CATHARANTHUS ROSEUS. The 9- and 10-oxo derivatives of geraniol, geranial, nerol, and neral as well as

Jasmonates enhance the expression of various genes involved in terpenoid indole alkaloid (TIA) biosynthesis in Catharanthus roseus. We applied precursor feeding to our C. roseus suspensions to determine how methyl jasmonate (MJ) alters the precursor availability for TIA biosynthesis. C. roseus

The 1-deoxy-D-xylulose-5-phosphate (DXP) pathway (non-mevalonate pathway) leading to terpenoids via isopentenyl diphosphate (IPP) has been shown to occur in most bacteria and in all higher plants. Treatment with the antibiotic fosmidomycin, a specific inhibitor of DXP reductoisomerase, considerably

The effects of terpenoid precursor feeding and elicitation by a biotic elicitor on alkaloid production of Catharanthus roseus suspension cultures were studied. After addition of secologanin, loganin or loganic acid an increase in the accumulation of ajmalicine and strictosidine and a decrease of

We have used a transgenic cell line of Catharanthus roseus (L.) G. Don to study the relative importance of the supply of biosynthetic precursors for the synthesis of terpenoid indole alkaloids. Line S10 carries a recombinant, constitutively overexpressed version of the endogenous strictosidine
Effect of precursor feeding on alkaloid accumulation by a tryptophan decarboxylase over-expressing transgenic cell line T22 of Catharanthus roseus.

To obtain more insight into the regulation of terpenoid indole alkaloid (TIA) biosynthesis in Catharanthus roseus (L.) G. Don cell cultures and particularly to identify possible rate limiting steps, a transgenic cell line over-expressing tryptophan decarboxylase (Tdc), and thus having a high level

The production of pharmaceutically important terpenoid indole alkaloids (TIAs) from Catharanthus roseus is partly regulated at the transcriptional level. In this study, limitations in TIA biosynthesis from C. roseus hairy root cultures were assessed through gene expression profiling and precursor

A rapid and simple reversed phase liquid chromatographic system has been developed for simultaneous analysis of terpenoid indole alkaloids (TIAs) and their precursors. This method allowed separation of 11 compounds consisting of eight TIAs (ajmalicine, serpentine, catharanthine, vindoline,
Characterization of a second secologanin synthase isoform producing both secologanin and secoxyloganin allows enhanced de novo assembly of a Catharanthus roseus transcriptome.

BACKGROUND
Transcriptome sequencing offers a great resource for the study of non-model plants such as Catharanthus roseus, which produces valuable monoterpenoid indole alkaloids (MIAs) via a complex biosynthetic pathway whose characterization is still undergoing. Transcriptome databases dedicated to

An isocratic HPLC system is described which allows the separation of the iridoid and indole precursors of terpenoid indole alkaloids, which are present in a single crude extract. The system consists of a column of LiChrospher 60 RP select B 5 microm, 250 x 4 mm (Merck) with an eluent of 1% formic

Omission of 2,4-D from culture medium during one subculture of Catharanthus roseus cells, strain C20, resulted in an increased alkaloid accumulation, without effect on growth. Alkaloid accumulation, rather than growth, seemed to be more sensitive to 2,4-D. 2,4-D inhibited alkaloid accumulation

Among the pharmacologically important terpenoid indole alkaloids produced by Catharanthus roseus are the anti-cancer drugs vinblastine and vincristine. These two drugs are produced in small yields within the plant, which makes them expensive to produce commercially. Metabolic engineering has focused

Catharanthus roseus (C. roseus) and Vinca minor (V. minor) are two common important medical plants belonging to the family Apocynaceae. In this study, we used non-targeted GC-MS and targeted LC-MS metabolomics to dissect the metabolic profile of two plants with comparable phenotypic and metabolic

Precursors from the terpenoid and tryptophan branches were fed to Catharanthus roseus to determine which of the two branches limits metabolic flux to indole alkaloids. The feeding of tryptophan at 17 days of the culture cycle produced auxin-like effects. Addition of low levels of auxin or tryptophan

Cd(II) is one of the most widespread and toxic heavy metals and seriously threatens plant growth, furthermore negatively affecting human health. For survival from this metal stress, plants always fight with Cd(II) toxicity by themselves or using other external factors. The effects of second metals
