Pollen grain of barley (Hordeum vulgare L.) - pattern of development

Acta Societatis Botanicorum Poloniae, 2014
Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

The cytoskeleton of pollen tubes and how it determines the physico-mechanical properties of cell wall

, 2017
The growth of pollen tubes is a complex process that requires the synchronized activity of many different factors. Pollen tubes grow by penetrating through relatively solid tissues of the pistil.

Peptide‐based antibacterial nanoplatforms: Design principles, stimuli‐regulated behaviors, and applications

Responsive Materials, EarlyView.
Peptide‐based antibacterial nanoplatforms, encompassing self‐assembled peptides and peptide‐engineered inorganic, polymeric, and lipid nanocarriers, are systematically reviewed. The article highlights design principles and stimuli‐responsive regulation for improving peptide stability, delivery efficiency, and antibacterial performance.

CaZAT5 delays the flowering time in tomato and affects pollen viability and anther dehiscence.

PLoS Genetics
Male sterility (MS) plays a crucial role in plant reproduction and hybrid breeding as it is associated with pollen viability and release. However, the regulatory mechanisms governing anther dehiscence in peppers remain poorly characterized.

The ultrastructure of pollen grain surface in allotetraploid petunia (Petunia hybrida hort. superbissima) as revealed by scanning electron microscopy

Acta Societatis Botanicorum Poloniae, 2015
The ultrastructure of pollen grain surface in allotetraploid petunias was analyzed by scanning electron microscopy. The pollen grain wall is developed into characteristic pattern of convulations.

Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

Sustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Short pollen profiles CF I (peat and underlying mineral soil) and CF III (mineral soil beneath wall), and pollen spectra from a plough mark

, 2020
The short monolith (19 cm of peat and 10 cm of the mineral soil beneath), CF Ib, was taken at 40 m NW of the Visitor Centre (VC), immediately to the north of a transverse stone-wall. Mineral soil from nearby that was sealed by the stone wall also sampled

Larvae of the Solitary Bee Epicharis bicolor Are a Rich Source of Yeasts, Including Four Novel Species of the Genera Starmerella, Wickerhamiella and Zygoascus

Yeast, EarlyView.
Four novel yeast species are described associated with larvae of the ground‐nesting solitary bee Epicharis bicolor in Brazil. These yeasts are described based on sequencing of the ITS‐5.8S region and D1/D2 domains of the large subunit of the rRNA gene and phylogenomic analyses.

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

Journal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.
