Plant Responses to Climate Change: The Case Study of Betulaceae and Poaceae Pollen Seasons (Northern Italy, Vignola, Emilia-Romagna)

open access: yesPlants, 2016
Aerobiological data have especially demonstrated that there is correlation between climate warming and the pollination season of plants. This paper focuses on airborne pollen monitoring of Betulaceae and Poaceae, two of the main plant groups with ...

Phylogenetic and Population Genetic Analysis Decipher the Taxonomic Consistency on Cryptic Betula costata Trautv. (Betulaceae) Populations in Japan and the Process on Its Divergence and Isolation

open access: yesPlant Species Biology, Volume 41, Issue 3, May 2026.
Betula costata, a deciduous broad‐leaved tree habits in the cool‐cold temperate forests in East Asia, is an ideal species for studying the persistence of relict plants. Although cryptic populations of this species have been reported in central Japan in recent years, species delineation of them using molecular evidence has not been undertaken.

Functional and Phylogenetic Implications of Canopy Mesophication in Temperate Hardwood Forests

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Mesophication describes the shifting of forests fire‐adapted systems to those dominated shaded‐adapted species, but the functional underpinnings of forest mesophication have received less quantitative testing. Using 20th century legacy datasets of changing forest composition in Wisconsin, USA, we characterized broad declines in drought tolerance, fire ...

Assessment of genetic diversity in natural European hophornbeam (Ostrya carpinifolia Scop.) populations in Turkey

open access: yesBiotechnology & Biotechnological Equipment, 2016
Genetic diversity is a crucial component for plant survivability and fitness in terms of adaptation, genetic stability and variability. In this study, a total of 160 genotypes were investigated using 12 random amplified polymorphic DNA (RAPD) primers to ...

Molecular IgE Reactivity Profiling With Micro‐Arrayed Allergens Reveals Distinct Interregional Patterns of Sensitization and a Hypoallergenic Region in Türkiye

open access: yesAllergy, Volume 81, Issue 4, Page 1247-1264, April 2026.
A prospective, systematic and cross‐sectional population study was performed involving 1000 adult subjects from five centers representing different climatic areas of Türkiye (Turkey). Molecular IgE profiling demonstrated substantial interregional variation and identified a hypoallergenic region in the easternmost area with a continental climate.

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe

open access: yesPlant Biology, Volume 28, Issue 3, Page 732-737, April 2026.
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Characterization of a Casuarina glauca Nodule-Specific Subtilisin-like Protease Gene, a Homolog of Alnus glutinosa ag12

open access: yesMolecular Plant-Microbe Interactions, 2000
In search of plant genes expressed during early interactions between Casuarina glauca and Frankia, we have isolated and characterized a C. glauca gene that has strong homology to subtilisin-like protease gene families of several plants including the ...
