Rhizosphere iron plaques derived from Fe-based nanomaterials (NMs) are a promising tool for sustainable agriculture. However, the requirement flooded conditions to generate plaque limits scope of NM application. In this study, we achieved in situ Fenton oxidation highly chlorinated persistent organic pollutant (2,2′,4,5,5′-pentachlorobiphenyl, PCB101) through mediated by interaction between α-Fe2O3 NMs and plant-rhizobacteria symbionts under dryland conditions. Mechanistically, coexistence Pseudomonas chlororaphis JD37 stimulated alfalfa roots secrete acidic reductive agents as well H2O2, which together rhizosphere reaction converted into rich Fe(II)-silicate. Further verifications reproduced vitro using compounds, confirming critical role •OH oxidative degradation PCB101. Significant reductions PCB101 content 18.6%, 42.9%, 23.2% were respectively found stem, leaf, soil after 120-d treatment, proving effectiveness NMs-plant-rhizobacteria technique simultaneously safe crop production remediation.

Detritusphere is a hotspot of carbon cycling in terrestrial ecosystems, yet the mineralization soil organic (SOC) within this microregion associated with reactive oxygen species (ROS) remains unclear. Herein, we investigated ROS production and distribution detritusphere six representative soils evaluated their contributions to SOC mineralization. We found that was significantly correlated several chemical biological factors, including pH, water-soluble phenols, water-extractable carbon, phenol oxidase activity, surface-bound or complexed Fe(II) low-crystalline minerals, highly crystalline Fe(II)-bearing SOC. These factors collectively contributed 99.6% variation production, as revealed by redundancy analyses. Among ROS, hydroxyl radicals (•OH) were key contributors mineralization, responsible for 10.4%-38.7% CO2 emissions quenching experiments. Inhibiting •OH decreased C-degrading enzyme activities, indicating stimulates increasing activity. Structural equation modeling further demonstrated promotes activities degrading phenols unlock "enzyme latch" availability upregulate gene expression. pathways equally exceeded its direct effect. findings provide detailed insight into mechanistic •OH-mediated dynamics detritusphere.

Reactive oxygen species (ROS), as redox messengers, play an important role in regulating plant growth, sensing biotic and abiotic stresses, integrating different environmental signals. As the microenvironment of interaction between root, soil microorganism, rhizosphere is hotspot ROS production action. Root exudates are medium for communication roots environment, they have a significant regulatory effect on rhizosphere. At same time, formation determined by coupling various factors, it also affected stresses such temperature, humidity, disease. This review summarizes how root affect growth induce defense mechanisms generation distribution ROS. It discusses promoting decomposition organic matter, nutrient cycling, pollutant degradation transformation. In-depth study regulation mechanism not only helps to reveal molecular adaptation stress but provides theoretical support practical guidance sustainable agricultural development ecological environment protection.

Hydroxyl radicals (•OH) are extensively produced from crystalline iron minerals under redox oscillation, during which their oxidizing impact on pollutant dynamics is often limited by low transportation. While natural organic matter exists as a ubiquitous mediator, how it regulates the distance scale of •OH production in heterogeneous system remains poorly understood. This study, for first time, reports an unrecognized route mediated humic acid (HA) extending spatial range oxygenation reduced hematite (rHem). The results showed that HA facilitated redistribution surface to solution, posing inverse impacts oxidation efficacies pollutants with varying accessibilities. It was difficult explain enhanced free using electron shuttling quinones or dissolved Fe-HA complexes. Comprehensive evidence demonstrated adsorbed preferentially consumed surface-bound trigger solid-to-liquid propagation carbon-centered (CCR•), dominantly promoting formation secondary far surface. Reactive-transport simulation and situ fluorescence visualized interfacial centimeter-scale long-range CCR•. Fourier transform ion cyclotron resonance mass spectrometry verified role decarboxylation CCR• generation. These findings offer new insights into environmental fate cycling engineered systems, including those matter.
