Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, Volume 81, Issue 8, Page 2675-2712, August 2026.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Effect of temperature on pollen germination for several Rosaceae species: influence of freezing conservation time on germination patterns [PDF]

PeerJ, 2019
Between February 2018 and April 2018, flowers were collected from eight Rosaceae species. Flowers were kept in a freezer at −20 °C for three freezing times (Treatment 1, two months; Treatment 2, four months; Treatment 3, six months).

Dehydration‐driven organization of metabolites into NaDES‐like assemblies in orthodox seeds

New Phytologist, Volume 251, Issue 3, Page 1172-1187, August 2026.
Summary Desiccation tolerance in plants, especially during orthodox seed dehydration, relies on compatible solute accumulation, complex molecular mechanisms, and intermolecular organizations that remain poorly understood. We combined metabolite profiling, mass spectrometry imaging, and electrospray and cold‐spray ionization mass spectrometry to ...

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development

New Phytologist, Volume 251, Issue 4, Page 2027-2040, August 2026.
Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.

Pollen longevity and viability dataset: an integrated resource for plant research and conservation

New Phytologist, Volume 251, Issue 4, Page 1631-1639, August 2026.
The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...
