Environmental Influence on the Untargeted Foliar Metabolome of Naturally Growing Mitragyna Species in Thailand

Plant-Environment Interactions, Volume 7, Issue 1, February 2026.
ABSTRACT This study investigates the foliar secondary metabolite profiles of four Mitragyna species naturally occurring in Thailand: M. diversifolia, M. hirsuta, M. rotundifolia, and M. speciosa (kratom). Using untargeted gas chromatography–mass spectrometry (GC–MS), 409 secondary volatile metabolites were annotated across the four species.

A cell‐type‐specific regulon controlling monoterpene indole alkaloid biosynthesis with feedback and feedforward activation loops

New Phytologist, Volume 249, Issue 2, Page 945-960, January 2026.
Summary Monoterpene indole alkaloids (MIA) are a diverse class of plant natural products produced by a subset of lineages within the Asterid clade of eudicots. The diversity of MIAs provides a unique opportunity to study not only the evolution of biosynthetic genes but also their regulation.
