Genome‐based discovery of pachysiphine synthases in Tabernaemontana elegans

The Plant Journal, Volume 120, Issue 5, Page 1880-1900, December 2024.
Significance Statement While pachysiphine is a monoterpene indole alkaloid of high interest and the precursor of an anti‐Alzheimer compound, its biosynthesis involving the epoxidation of tabersonine remains uncharacterized. By sequencing and assembling the genome of Tabernaemontana elegans, we identified two P450s exhibiting a pachysiphine synthase ...

Jasmonic Acid Effect on the Fatty Acid and Terpenoid Indole Alkaloid Accumulation in Cell Suspension Cultures of Catharanthus roseus

Molecules, 2014
The stress response after jasmonic acid (JA) treatment was studied in cell suspension cultures of Catharanthus roseus. The effect of JA on the primary and secondary metabolism was based on changes in profiles of fatty acids (FA) and terpenoid indole ...

The evolution and history of Vinca alkaloids: From the Big Bang to the treatment of pediatric acute leukemia

Pediatric Blood &Cancer, Volume 71, Issue 11, November 2024.
Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...

An updated version of the Madagascar periwinkle genome [version 1; peer review: 2 approved]

F1000Research, 2022
The Madagascar periwinkle, Catharanthus roseus, belongs to the Apocynaceae family. This medicinal plant, endemic to Madagascar, produces many important drugs including the monoterpene indole alkaloids (MIA) vincristine and vinblastine used to treat cancer worldwide. Here, we provide a new version of the C.
