Cross‐stage single‐cell and spatial metabolome analyses reveal periderm specialization and tanshinone biosynthesis in Salvia miltiorrhiza roots

New Phytologist, EarlyView.
Biosynthesis and accumulation of tanshinones in the periderm of Salvia miltiorrhiza during secondary root growth. Summary Perennial herbs develop long‐lived roots that undergo repeated cycles of secondary growth, during which the periderm functions as a protective barrier and a major site of specialized metabolite accumulation.

The Cadin-2-en-1β-ol-1β-d-glucuronopyranoside Suppresses TPA-Mediated Matrix Metalloproteinase-9 Expression Through the ERK Signaling Pathway in MCF-7 Human Breast Adenocarcinoma Cells

Journal of Pharmacological Sciences, 2012
A sesquiterpene glycoside, cadin-2-en-1β-ol-1β-D-glucuronopyranoside (known as CR4-1), was isolated from Catharanthus roseus (Apocynaceae) hairy root cultures. C. roseus is widely used as an ornamental and medicinal plant and is cultivated mainly for its

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Discovery of a Plant Pictet–Spenglerase With R‐Stereoselectivity

Angewandte Chemie, Volume 138, Issue 20, 11 May 2026.
Strictosidine synthases (STRs) are plant Pictet–Spenglerases catalyzing the coupling of a secoiridoid with tryptamine. All previously characterized strictosidine synthases are strictly S‐selective. Here, we report the discovery of Epi‐STR, an R‐selective STR ortholog from the medicinal plant Pogonopus speciosus.
