A Systematic Review of the Pharmacological and Phytochemical Profiles of Madagascar periwinkle as Potential Dietary Supplement

Chinese Journal of Applied Physiology, 2023
Madagascar periwinkle (Catharanthus roseus) is a plant species known for its rich pharmacological and phytochemical properties. This systematic review aims to comprehensively evaluate the potential of Madagascar periwinkle as a dietary supplement. A thorough search of relevant databases yielded studies focusing on the pharmacological activities and ...

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 ...

Colonization of Madagascar periwinkle (Catharanthus roseus), by endophytes encoding gfp marker

Archives of Microbiology, 2013
This study reports the introduction of gfp marker in two endophytic bacterial strains (Pantoea agglomerans C33.1, isolated from cocoa, and Enterobacter cloacae PR2/7, isolated from citrus) to monitor the colonization in Madagascar perinwinkle (Catharanthus roseus).

Transformation in Catharanthus Species (Madagascar Periwinkle)

1993
Secondary 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.

Gene expression profiling of phytoplasma-infected Madagascar periwinkle leaves using differential display

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.

Molecular cloning and characterisation of two calmodulin isoforms of the Madagascar periwinkle Catharanthus roseus

Plant Biology, 2010
AbstractInvolvement of Ca2+signalling in regulation of the biosynthesis of monoterpene indole alkaloids (MIA) in Catharanthus roseus has been extensively studied in recent years, albeit no protein of this signalling pathway has been isolated. Using a PCR strategy, two C.

Multiple forms of NADPH-cytochrome P450 oxidoreductases in the madagascar periwinkle Catharanthus roseus

In Vitro Cellular & Developmental Biology - Plant, 2001
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

Growth and alkaloids production in Madagascar periwinkle plants grown under red LED

IFAC Proceedings Volumes, 2013
Abstract Madagascar periwinkle plants containing physiologically active indole alkaloids were grown hydroponically under red light (R) from red Light-Emitting Diodes (LEDs; 660nm peak wavelength) or white light (FL) from fluorescent lamps in the enclosed artificial lighting plant factory. The effects of light quality on growth and vindoline (VIN) and

Anthracnose of Madagascar periwinkle caused by species belonging to the Colletotrichum gloeosporioides species complex

Journal of General Plant Pathology, 2013
Severe blight of stems was found on Madagascar periwinkle (Catharanthus roseus) in Shizuoka and Okinawa prefectures, Japan, in July 2003 and September 2004, respectively. Similar fungi were isolated from the diseased plants. The isolated fungi caused the disease after inoculation and subsequently were reisolated from diseased tissues.
