The interplay between root exudates and rhizobacteria is essential for enhancing agricultural productivity. Herein, the impacts of cerium dioxide nanomaterials (CeO NMs) on these interactions in soybean plants were investigated. Following 3-5 weeks of exposure to 5 mg·kg CeO NMs, the composition of root exudates changed over time, with isoflavone levels increasing by 6.

Understanding the responses of desert microbial communities to escalating precipitation changes is a significant knowledge gap in predicting future soil health and ecological function. Through a five-year precipitation manipulation experiment, we investigated the contrasting eco-evolutionary processes of desert bacteria and fungi that manifested in changes to the assembly and potential functions of the soil microbiome. Elevated precipitation increased the alpha diversity and network complexity of bacteria and fungi, proportion of non-dominant phyla, and abundance of carbon- and nitrogen-fixing bacteria and saprophytic, symbiotic, and pathogenic fungi.

College of Environment, Hohai University, Nanjing 210024, China.
The expansion of aquaculture areas has encroached upon vast areas of coastal wetlands and introduced excessive nitrogen inputs, disrupting microbial communities and contributing to various environmental issues. However, investigations on how aquaculture affects microbial communities and nitrogen metabolism mechanisms in coastal tidal flats remain scarce. Hence, we explored the composition, diversity, and assembly processes of nitrogen-cycling (N-cycling) microbial communities in tidal flats in Jiangsu using metagenomic assembly methods.

Independent Researcher, Geel, Belgium.
The radionuclide contamination of the environment is an abiotic stress factor that influences biological systems. Plants growing in contaminated areas for many generations provide a unique opportunity to study adaptive strategies aimed at maintaining homeostasis under elevated radiation levels. Using non-targeted metabolomics approaches, we investigated the metabolomic profiles of Achillea millefolium L.

Focal adhesions (FAs), multi-protein complexes that link the extracellular matrix to the intracellular cytoskeleton, are key mediators of cell adhesion, migration, and proliferation. These dynamic structures act as mechanical sensors, transmitting stimuli from the extracellular to intracellular environment activating in this way signaling pathways and enabling cells to adapt to environmental changes. As such, FAs are critical for tissue organization and serve as hubs governing cell spatial arrangement within the organism.
