The effect of soil physicochemical properties on intraspecific variability of pollen morphology in Staphylea pinnata L.

open access: yesScientific Reports
Soil properties influence various aspects of plant growth, development and reproduction. Despite the importance of the gametophytic phase in the plant life cycle, its response to soil factors remains poorly understood, particularly in wild plants.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Pollen morphology of three invasive Impatiens species in Europe under varying habitat conditions—a case study from Poland

open access: yesScientific Reports
The effect of the habitat conditions on the pollen features of invasive species has not been studied so far, and may affect the quality of their generative reproduction and contribute to the development of more effective methods of their control.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

open access: yesAdvanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes

open access: yesAdvanced Science, EarlyView.
In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

Distribution and habitat preferences of Polygonum arenarium subsp. arenarium ( Polygonaceae ) in Slovakia

open access: yesPlant and Fungal Systematics, 2018
The paper presents data on the distribution and habitat preferences of Polygonum arenarium subsp. arenarium in Slovakia. The study showed a rapid decrease in the number of localities in Slovakia in recent decades, due to destruction of sandy habitats.

Noninvasive Characterization of Tumor Heterogeneity in HNSCC: From Clinical Utility to Biological Correlates

open access: yesAdvanced Science, EarlyView.
This study establishes a CT‐based radiomics framework to quantify intratumoral heterogeneity (ITH) in HNSCC. Using unsupervised clustering, tumor ROIs and VOIs are analyzed to calculate 2D/3D ITH scores. The score shows strong predictive value for prognosis and immunotherapy response, and is associated with tumor metabolism and immune microenvironment,
