Urban rendezvous: Spatiotemporal overlap is more important than abundance and trait matching for urban plant–pollinator interactions

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

open access: yesNew Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Pathogenicity and Protein Expression Analysis of Macrophomina pseudophaseolina in Cucumis melo

open access: yesJournal of Phytopathology, Volume 173, Issue 6, November/December 2025.
ABSTRACT Melon is a major crop cultivated in the Brazilian Semiarid region. Several soilborne fungal pathogens cause root rot and vine decline (RRVD) in commercial production areas. This study evaluated the pathogenicity of Macrophomina pseudophaseolina isolates in melon accessions and characterised their differentially expressed protein profiles using

Exploring the importance of aromatic plants' extrafloral volatiles for pollinator attraction

open access: yesNew Phytologist, Volume 248, Issue 2, Page 517-528, October 2025.
Summary Aromatic plants occur in many plant lineages and have widespread ethnobiological significance. Yet, the ecological significance and evolutionary origins of aromatic volatile emissions remain uncertain. Aromatic emissions have been implicated in defensive interactions but may also have other important functions.
