Abstract ：
Viruses are ubiquitous, and their potential impacts on biogeochemical cycles in soil have largely been inferred from correlation evidence and virome studies. Manure has been demonstrated to affect nitrogen cycle by altering soil nutrients and microbial communities. However, the direct impacts of viruses derived from manure on microbial community, nitrification, and denitrification remained exclusive. In this study, concentrated viral extracts obtained from manure were added into an agricultural soil in varying dosages: a one-time addition of 10-fold viruses or a weekly addition of 1-fold viruses for ten weeks. The results showed that both viral extracts and manure significantly changed the microbial community compositions and structures. The effect of manure on microbial diversity was concentration-dependent, differing from the viral impact on microbial diversity in soil. Deterministic processes predominated in the assembly of microbial communities in both viral and manure treatments, with an increased contribution of deterministic processes observed after these treatments. Additionally, a high concentration (10-fold) of viruses enhanced N2O production and reduction in soil. In the control treatment, N2O production was driven by bacterial denitrification, fungal denitrification, and chemodenitrification. However, bacteria became the dominant driver of N2O production in both virus and manure treatments. Overall, experimental evidence for viral impacts on the composition and assembly of microbial community, as well as on nitrification and denitrification processes, was provided through a 70-day microcosm experiment. These findings highlight the importance of viruses in regulating the distribution and functioning of microbes in terrestrial ecosystems.

Abstract ：
Mercury (Hg) contamination in paddy systems poses severe environmental and public health threats due to the microbial transformation of inorganic Hg into highly toxic methylmercury (MeHg). Although biochar (BC) has been widely applied for heavy metal remediation, its limited capacity to immobilize Hg constrains its practical effectiveness. Here, we present a comprehensive study combining batch experiments and density functional theory (DFT) calculations to elucidate the molecular mechanisms by which iron-modified biochar (Fe-BC) enhances Hg stabilization and inhibits MeHg formation in paddy systems. Our results reveal that Fe modification induces the coordination of FeOOH clusters with oxygen-containing functional groups and aromatic domains on the BC surface, significantly enhancing its Hg-affinity. Notably, the structural stability and adsorption performance of Fe-BC are strongly size-dependent, with the FeOOH dimer (FeOOH)2 showing the most robust binding to BC and the highest capacity for Hg immobilization. Fe-BC application markedly reduces both MeHg production and bioavailability in the contaminated paddy by strengthening Hg adsorption through interactions with sub-nanometer FeOOH clusters, especially (FeOOH)2 anchored on the aromatic structures of BC. Furthermore, we demonstrate that coexisting soil ions modulate Hg adsorption: Na+ reduces Hg binding via electrostatic competition, whereas Cl-and SO42-promote stable complex formation (Fe-BC-Hg-Cl and Fe-BC-Hg-SO4), further enhancing Hg retention. These findings provide molecular-level insight into Fe-BC's stabilization mechanisms and highlight the importance of optimizing Fe cluster structures and ion interactions to maximize remediation efficiency. This study offers both theoretical and practical guidance for advancing Fe-BC-based strategies for sustainable Hg immobilization in contaminated paddy systems.

Abstract ：
The co-contamination of arsenic (As) and cadmium (Cd) in paddy soils threatens rice safety, yet synergistic mitigation strategies using silicon (Si) and ferrous sulfate (FeSO4) remain underexplored. This study integrated hydroponic and soil pot experiments to evaluate Si-FeSO4 interactions on As/Cd accumulation and rice growth. Hydroponic trials employed 21-day-old rice seedlings exposed to 0.5 mg As(III)/Cd(II) L-1 with/without 70 mg Si L-1 and 30-70 mg Fe L-1, followed by sequential harvesting at 14 and 21 days. Soil experiments utilized co-contaminated paddy soil (50 mg As kg(-1) and 1.2 mg Cd kg(-1)) amended with Si (80 or 400 mg kg(-1)) and Fe (100 or 1000 mg kg(-1)), with pore water dynamics monitored over 120 days. Hydroponic results demonstrated that 70 mg Si L-1 combined with 30 or 70 mg Fe L-1 enhanced shoot biomass by 12-79% under As stress, while simultaneously reducing shoot As concentrations by 76-87% and Cd concentrations by 14-33%. Iron plaque induced by FeSO4 exhibited contrasting adsorption behaviors: hydroponic roots immobilized both As and Cd (p < 0.01), whereas roots in soil primarily retained Cd (p < 0.05). In soil experiments, the optimal treatment of 100 mg Fe kg(-1) and 400 mg Si kg(-1) (Fe-1 + Si-2) increased grain biomass by 54%, while reducing As and Cd concentrations by 37% and 42%, respectively. However, a higher Fe dosage (Fe-2: 1000 mg kg(-1) Fe) paradoxically increased grain Cd concentrations. Mechanistically, Si amendment elevated soil pH (Delta + 0.72), facilitating Cd immobilization, while FeSO4 lowered pH (Delta-0.07-0.53), increasing Cd mobility. A strong correlation between soluble Cd and plant uptake was observed (p < 0.01), while changes in As accumulation were unrelated to aqueous behavior. The optimized Si/Fe molar ratio of 7.95:1 effectively mitigated As and Cd co-accumulation, offering a dual-functional strategy for safe rice cultivation in contaminated soils.

Abstract ：
This study aimed to evaluate the effects of specific LED light spectra on the growth and physiology of Changchuan No. 3 Capsicum annuum L. seedlings. The experimental design involved exposing pepper seedlings to six different spectral light combinations for 7, 14, and 21 days, with the treatments consisting of 2R1B1Y (red/blue/yellow = 2:1:1), 2R1B1FR (red/blue/far-red = 2:1:1), 2R1B1P (red/blue/purple = 2:1:1), 4R2B1G (red/blue/green = 4:2:1), 2R1B1G (red/blue/green = 2:1:1), and 2R1B (red/blue = 2:1). The results demonstrated distinct spectral regulation of seedling development: compared to the white light (CK), the 2R1B1FR (far-red light supplementation) treatment progressively stimulated stem elongation, increasing plant height and stem diameter by 81.6% and 25.9%, respectively, at day 21, but resulted in a more slender stem architecture. The 2R1B1G (balanced green light) treatment consistently promoted balanced growth, culminating in the highest seedling vigor index at the final stage. The 2R1B1P (purple light supplementation) treatment exhibited a strong promotive effect on root development, which became most pronounced at day 21 (126% increase in root dry weight), while concurrently enhancing soluble sugar content and reducing oxidative stress. Conversely, the 2R1B1Y (yellow light supplementation) treatment increased MDA content by 70% and led to a reduction in chlorophyll accumulation, while 2R1B (basic red-blue) resulted in lower biomass accumulation compared to the superior spectral treatments. The 4R2B1G (low green ratio) treatment showed context-dependent outcomes. This study elucidates how targeted spectral compositions, particularly involving far-red and green light, can optimize pepper seedling quality by modulating photomorphogenesis, carbon allocation, and stress physiology. The findings provide a mechanistic basis for designing efficient LED lighting protocols in controlled-environment agriculture to enhance pepper nursery production.

Abstract ：
To reveal differences in arsenic (As) accumulation among indica rice cultivars and assess the human health risks arising from inorganic arsenic (iAs) intake via rice consumption, a total of 320 field indica rice samples and corresponding soil samples were collected from Fujian Province in China. The results showed that available soil As (0.03 to 3.83 mg/kg) showed a statistically significant positive correlation with total soil As (0.10 to 19.45 mg/kg). The inorganic As content in brown rice was between 0.001 and 0.316 mg/kg. Among the cultivars, ten brown rice samples (3.13%) exceeded the maximum contaminant level (MCL) of iAs in food of 0.2 mg/kg in China. The estimated daily intake (EDI) and calculated individual incremental lifetime cancer risk (ILCR) ranged from 0.337 mu g/day to 106.60 mu g/day and from 8.18 x 10(-6 )to 2.59 x 10(-3), respectively. Surprisingly, the average EDI and the EDIs of 258 (80.63%) brown rice samples were higher than the maximum daily intake (MDI) of 10 mu g/day in drinking water as set by the National Research Council. The mean ILCR associated with iAs was 54.3 per 100,000, which exceeds the acceptable upper limit (AUL) of 10 per 100,000 set by the USEPA. Notably, the cultivars Y-Liang-You 1 and Shi-Ji 137 exhibited significantly higher mean ILCRs compared to the AUL and other cultivars, indicating that they pose more serious cancer risks to the local population. Finally, this study demonstrated that the cultivars Yi-Xiang 2292 and Quan-Zhen 10 were the optimal cultivars to mitigate risks associated with iAs to human health from rice consumption.

Abstract ：
Excessive cadmium (Cd) in rice, caused by Cd pollution of farmlands, poses a serious threat to human health. In this study, a pot experiment was conducted to investigate the effects of two doses of CaCO3 (Ca1: 2 g kg -1, Ca2: 10g kg -1), two types of Fe(II) (EDTA-Fe(II) and FeSO4; 0.14 g Fe kg -1), and their combined application on the uptake and accumulation of Cd in rice plants grown in Cd-contaminated acidic soil. The results revealed that FeSO4 significantly increased rice grain biomass, whereas the other treatments had no significant effects. Further, the addition of EDTA-Fe(II) or FeSO4 significantly enhanced iron plaque formation on the root surface and increased the Fe content in the rice plants and porewater. Compared to the control, CaCO3 addition weakened the formation of iron plaque and reduced the Fe concentration in the porewater and root tissue, stems and leaves, whereas the Fe concentration in brown rice and the husks remained unaffected. Combined application of CaCO3 and Fe(II) significantly promoted the formation of iron plaque and increased the Fe concentration in brown rice. However, the Cd concentration in the iron plaque was reduced by CaCO3 addition but increased by Fe(II) treatment. Notably, all treatments reduced the Cd concentration in all rice plant tissues. The application of Ca1, Ca2, EDTA-Fe(II), FeSO4, Ca1+EDTA-Fe(II), Ca1+FeSO4, Ca2+EDTA-Fe(II) and Ca2+FeSO4 significantly reduced the Cd concentration in brown rice by 69%, 63%, 51%, 60%, 46%, 39%, 38%, and 29%, respectively. These results indicate that the application of CaCO3, EDTA-Fe(II)/FeSO4, or their combination can effectively reduce Cd accumulation and translocation in rice plants.

Abstract ：
Despite extensive research on Fe-based materials for soil cadmium(Cd) passivation, the combined effects with Ca agents on rice Cd migration remain unclear. This study examined the effects of NZVI, FeSO4 and their mixtures with CaCO3 on iron plaque formation and Cd translocation in rice plants grown in Cd-contaminated paddy soils. Results showed both NZVI and FeSO4 significantly increased rice biomass. FeSO4, NZVI, FeSO4+CaCO3, and NZVI+CaCO3 enhanced iron plaque by 65%, 72%, 77%, and 20%, respectively. Cd adsorption by iron plaque increased by 88% with FeSO4, 39% with NZVI, 49% with FeSO4+CaCO3, and decreased by 44% with NZVI+CaCO3. All treatments reduced Cd content in rice tissues, with brown rice Cd concentrations reduced by 66% with FeSO4, 58% with FeSO4+CaCO3, 45% with NZVI, and 39% with NZVI+CaCO3, respectively. This study highlights Fe-based amendments' potential in safely utilizing Cd-contaminated farmlands, showing standalone Fe treatments outperform Fe-Ca combination for reducing Cd in brown rice.

Abstract ：
Sulfur and biochar are two important agents for remediating heavy metal-polluted soils. Nevertheless, the double-edged sword effect of sulfur and the relatively limited efficacy of biochar in addressing soil mercury (Hg) contamination have constrained its practical use in Hg-polluted areas. This study developed an optimized strategy involving the combined application of biochar and sulfate to reduce soil methylmercury (MeHg) production and grain MeHg accumulation and revealed the underlying molecular mechanisms governing the interactions among sulfate, biochar, and Hg, based on both batch experiments and density functional theory calculations. Our findings demonstrate that the combined use of biochar and sulfate at optimal proportions can effectively promote rice crop growth while mitigating grain MeHg accumulation. This positive effect is attributed to the strong adsorption capacity of carboxylic and phenolic hydroxyl groups in biochar for soil Hg. Sulfate can further enhance the stability of adsorbed Hg(II), forming a highly stable biochar-Hg(-SO4)-Cl structure in soil, thereby mitigating MeHg production. Meanwhile, the suppression of Hg methylator activity, coupled with alterations in soil pH, and the chemical speciation of Fe and Mn upon biochar addition, indirectly counteracts sulfate-stimulated microbial Hg-methylation in paddy soils. This research highlights the effectiveness of a combined biochar and sulfate application strategy in Hg sequestration and reduction of MeHg accumulation in grains. By unveiling the molecular mechanisms underlying the interactions among sulfate, biochar, and Hg in soil, our study offers fresh insights for designing more efficient and safe strategies aimed at enhancing rice yields while mitigating the risks associated with soil Hg pollution.

Excessive cadmium (Cd) in rice, caused by Cd pollution in farmland, poses a serious threat to human health. A pot experiment was conducted to investigate the effects of two doses of CaCO3 (Ca1: 2 g kg-1, Ca2: 10g kg-1), two types of Fe(II) (EDTA-Fe(II) and FeSO4 (0.14 g Fe kg-1)), and their combination application on the uptake and accumulation of Cd in rice plant in pot trials with Cd-contaminated acidic soil. Results revealed that FeSO4 significantly increased rice grain biomass, whereas other treatments had no significant effect. The application of CaCO3 weakened the formation of Fe plaque and reduced Fe concentration in porewater and root tissue, stem and leaf, but Fe concentration in brown rice and husk remained unaffected. Fe(II) and CaCO3+Fe(II) significantly promoted the formation of Fe plaque and increased Fe concentration in brown rice. Cd concentration in Fe plaque was reduced by CaCO3, while it was increased by Fe(II), respectively. All treatments significantly reduced Cd concentration in all tissues of rice plant. The application of Ca1, Ca2, EDTA-Fe(II), FeSO4, Ca1+EDTA-Fe(II), Ca1+FeSO4, Ca2+EDTA-Fe(II) and Ca2+FeSO4 resulted in a significant reduction of Cd concentration in brown rice by 69%, 63%, 51%, 60%, 46%, 39%, 38%, and 29%, respectively. Soil pH decreased after rice harvest, but all treatments significantly increased soil pH by 0.71-1.65 units. During the growth period of the rice plant, Cd and Fe concentrations in porewater generally showed a gradual decrease trend. At 90 and 120 days, all treatments reduced Cd concentration in porewater, but Fe(II) or CaCO3+Fe(II) increased Fe concentration in porewater. These results indicate that the application of CaCO3, EDTA-Fe(II)/FeSO4, and their combination is effective in immobilizing Cd and reducing Cd uptake by rice plants, although long-term trials are required to validate these findings. © 2023, The Authors.
