The Madagascar periwinkle produces a large palette of Monoterpenoid Indole Alkaloids (MIAs), a class of complex alkaloids including some of the most valuable plant natural products with precious therapeutical values. Evolutionary pressure on one of the hotspots of biodiversity has obviously turned this endemic Malagasy plant into an innovative alkaloid

Missing enzymes in the biosynthesis of the anticancer drug vinblastine in Madagascar periwinkle
Science, 2018How to make bioactive alkaloids Vinblastine and vincristine are important, expensive anticancer agents that are produced by dimerization of the plant-derived alkaloids catharanthine and vindoline. The enzymes that transform tabersonine into vindoline are known; however, the mechanism by which the scaffolds of catharanthine and ...

Green grabbing at the ‘pharm’ gate: rosy periwinkle production in southern Madagascar
Journal of Peasant Studies, 2012The following article contrasts contemporary rosy periwinkle (Catharanthus roseus) extraction in southern Madagascar with original bioprospecting research conducted 50 years ago. My study shows how plant extraction firms have shifted their approaches by creating new labor forms, which devolve risk and increase exploitation in attempts to capture the ...

A 7-Deoxyloganetic Acid Glucosyltransferase Contributes a Key Step in Secologanin Biosynthesis in Madagascar Periwinkle [PDF]
Plant Cell, 2013 Abstract Iridoids form a broad and versatile class of biologically active molecules found in thousands of plant species. In addition to the many hundreds of iridoids occurring in plants, some iridoids, such as secologanin, serve as key building blocks in the biosynthesis of thousands of monoterpene indole alkaloids (MIAs) and many ...

Transformation in Catharanthus Species (Madagascar Periwinkle)
1993Secondary metabolite production by plant cell cultures has been the subject of many investigations. Indole alkaloids such as ajmalicine, an antihypertensive drug, or vinblastine and vincristin, two antitumor compounds produced by Catharanthus roseus, are very important in the pharmaceutical industry.

Molecular Biology Reports, 2010
Phytoplasmas are small (0.2-0.8 μm), wall-less, pleiomorphic prokaryotes responsible of numerous economically important plant diseases. They are characterized by a very small genome and are obligate parasites of phloem tissues and some insects that act as vectors of infection.

NADPH-cytochrome P450 oxidoreductase (CPR, EC 1.6.2.4) is the redox partner of classical P450-monooxygenases, which have crucial roles in the metabolism of terpenes, alkaloids, flavonoids, phytoalexins, etc. It becomes evident that, contrary to animals and yeast, various CPR isoforms occur in some plants, although their specific physiological functions
