Context matters: Photoperiodic light spectrum modulates UV-A-induced alkaloid profile and oxidative signaling in Catharanthus roseus

Scientia Horticulturae
Catharanthus roseus produces pharmacologically relevant terpenoid indole alkaloids (TIAs), including vinblastine (VLB) and vincristine (VCR). However, their low natural abundance makes it essential to optimize C.

Chemical and Biological Perspectives of Monoterpene Indole Alkaloids From Rauwolfia species

, 2018
The biosynthesis of monoterpene indole alkaloids (MIAs) starts with a geraniol for the terpenoid portion. Secologanin, a secoiridoid glycoside, is derived from 10-hydroxygeraniol, produced in the presence of geraniol 10-hydroxylase. The indole portion
