Long‐term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

New Phytologist, Volume 251, Issue 4, Page 2091-2106, August 2026.
Documented incursions of Puccinia striiformis 2009–2023 based on sequential resampling of MLGs/pathogen races on different continents. Summary Evolutionary forces affecting crop pathogens, including hybridization and long‐distance dispersal (LDD), may have strong implications for food security and sustainable plant disease control at global scales ...

Identification of Pyrrolizidine Alkaloids in Senecio Plants by Liquid Chromatography-Mass Spectrometry

Journal of Analytical Methods in Chemistry, 2021
Pyrrolizidine alkaloids (PAs) are considered as the major constituents that cause hepatoxicity in Senecio plants. PAs can be found in about 3%–5% of the world’s flowering plants.

Deciphering Darwin's Conundrum Through the Asteraeceae Family in an Oceanic Archipelago: A Phylogenomic‐Functional Approach

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Biological invasions are a major threat to global biodiversity, with a particular strong impact on oceanic islands and their unique and fragile biotas. However, the complexity of the processes underlying invasions has prevented the identification of general patterns explaining why some plant species successfully establish and spread beyond

Seasonal Drought Timing Shapes Flowering Phenology Directly and Through Biotic Interactions

Ecology Letters, Volume 29, Issue 7, July 2026.
The effects of drought on flowering depend on when drought occurs during the growing season. In experimental monocultures and mixtures, autumn drought delayed flowering onset whereas spring drought advanced flowering termination, with both reducing flowering duration through direct physiological effects and competition‐mediated interactions.
