Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Complex engineering of Solanum alkaloids structural diversity in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
Summary Transient expression in Nicotiana benthamiana offers a powerful and versatile platform for rapid production of complex specialized metabolites. Steroidal glycoalkaloids (SGAs) and steroidal saponins produced by members of the Solanaceae family are known for their diverse structures and activities including antimicrobial, anticancer, antiviral ...

Enhanced Selectivity of Chalcogen Bonding over Halogen Bonding Catalyzed C‐glycosylation Through Differentiated Intermediate Activation

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
By harnessing chalcogen bonding (ChB) catalysis, an exclusive access into a highly stereoselective strain‐release C‐glycosylation pathway was discovered. This was surprisingly not replicable by the conceptually similar halogen bonding (XB) catalysis.

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Rewiring Steroidal Metabolic Pathways for Diosgenin Production in Solanum nigrum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Diosgenin is a key starting material for the synthesis of steroidal drugs, such as corticosteroids and sex hormones. While the primary commercial source of diosgenin is the tubers of Dioscorea spp., identifying alternative plant hosts capable of diosgenin biosynthesis could enhance its production.

Advancing Structure Elucidation with a Flexible Multi‐Spectral AI Model

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
The MultiModalSpectralTransformer (MMST) is an automated tool that helps identify molecular structures by combining different spectroscopic methods, including 2D and 1D NMR, IR, and MS, within a unified AI framework. Trained on 4 million simulated compounds, MMST achieves 72% top‐1 accuracy in molecular identification and adapts to new chemical spaces ...
