Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The highly threatened African cycad genus Encephalartos faces severe threats such as habitat loss and poaching. In addition, the lack of sexual recruitment due to the absence of pollinators (pollinator collapse) has emerged as another major threat.

Plant Biotechnology Journal, EarlyView.BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Resilience of floral scent emission after florivory
Plant Biology, EarlyView.Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Regiodivergent C3 and C4 Amination of Quinolines via Radical and Ionic Pathways
Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.A regiodivergent strategy converts a single N‐aminoquinolinium precursor into either C3‐ or C4‐aminated quinolines. Nucleophile‐induced dearomatization diverges into light‐driven N‐centered radical capture (C3) or base‐promoted SNAr (C4), enabling rapid assembly of aminoquinoline libraries and late‐stage diversification.

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism
New Phytologist, Volume 250, Issue 5, Page 3428-3443, June 2026.Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

Mo‐Catalyzed Synthesis of N‐Polyheterocycles From Functionalized Nitroarenes and Aldehydes
Asian Journal of Organic Chemistry, Volume 15, Issue 5, May 2026.Mo(VI)‐catalyzed one‐pot conversion of readily available functionalized nitroarenes and aldehydes yielded fused N‐polyheterocycles by sequential nitro reduction, imine formation, and cyclization. Using pinacol as a benign reductant, this sustainable tandem strategy suppresses side reactions and grants rapid access to diverse pharmacologically relevant ...

Flavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Small, Volume 22, Issue 26, 8 May 2026.Incorporation of p‐phenylenediamine (pPD) into the polymer–pPD supramolecular artificial SEI reduces the activation energy for Li‐ion desolvation at the interface and promotes Li‐ion transport through the layer, thereby ensuring uniform delivery of Li‐ion into the SCN and stable cycling performance regardless of the inherently uneven thickness of the ...

Fungal Pathogen Activity and Stress‐Dependent Responses of Grapevine Wood to Esca and Drought
Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.ABSTRACT Biotic and abiotic stresses alter the physiology of perennial plants, with consequences for fungal endophytes and disease expression. In grapevine, drought inhibits esca disease expression, but the underlying molecular interactions between the plant and fungi are unknown. We combined wood metatranscriptomics, metabolomics, and metabarcoding to
