摘要：
Organic matter (OM) derived from the decomposition of crop residues plays a key role as a sorbent for cadmium (Cd) immobilization. Few studies have explored the straw decomposition processes with the presence of minerals, and the effect of newly generated organo-mineral complexes on heavy metal adsorption. In this study, we investigated the variations in structure and composition during the rice straw decomposition with or without minerals (goethite and kaolinite), as well as the adsorption behavior and mechanisms by which straw decomposition affects Cd immobilization. The degree of humification of extracted straw organic matter was assessed using excitation-emission matrix (EEM) fluorescence and Ultraviolet-visible spectroscopy (UV-vis), while employing FTIR spectroscopy and XPS to characterize the adsorption mechanisms. The spectra analysis revealed the enrichment of highly aromatic and hydrophobic components, indicating that the degree of straw decomposition and humification were further intensified during incubation. Additionally, the existence of goethite (SG) accelerated the humification of OM. Sorption experiments revealed that the straw humification increased Cd adsorption capacity. Notably, SG exhibited significantly higher adsorption performance compared to the organic matter without minerals (RS) and the existence of kaolinite (SK). Further analysis using FT-IR spectroscopy and XPS verified that the primary mechanisms involved in Cd immobilization were complexion with —OH and —COOH, as well as the formation of Cd-π binds with aromatic C=C on the surface of solid OMs. These findings will facilitate understanding the interactions of the rice straw decomposing with soil minerals and its remediation effect on Cd-contaminated farmland.
摘要：
Lignin and cellulose are two essential elements of plant secondary cell walls that shape the mechanical characteristics of the culm to prevent lodging. However, how the regulation of the lignin and cellulose composition is combined to achieve optimal mechanical characteristics is unclear. Here, we show that increasing OsTCP19 expression in rice coordinately repressed lignin biosynthesis and promoted cellulose biosynthesis, resulting in enhanced lodging resistance. In contrast, repression of OsTCP19 coordinately promoted lignin biosynthesis and inhibited cellulose biosynthesis, leading to greater susceptibility to lodging. We found that OsTCP19 binds to the promoters of both MYB108 and MYB103L to increase their expression, with the former being responsible for repressing lignin biosynthesis and the latter for promoting cellulose biosynthesis. Moreover, up-regulation of OsTCP19 in fibers improved grain yield and lodging resistance. Thus, our results identify the OsTCP19-OsMYB108/OsMYB103L module as a key regulator of lignin and cellulose production in rice, and open up the possibility for precisely manipulating lignin-cellulose composition to improve culm mechanical properties for lodging resistance.
摘要：
To investigate the differential immunology in Ningxiang and Berkshire pigs and their F1 offspring (F1 offspring), physiological and biochemical indicators in the plasma and spleen were analyzed. Then, transcriptomic analysis of the spleen identified 1348, 408, and 207 differentially expressed genes (DEGs) in comparisons of Ningxiang vs. Berkshire, Berkshire vs. F1 offspring, and Ningxiang vs. F1 offspring, respectively. In Ningxiang vs. Berkshire pigs, the gene ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that the DEGs included CD163, MARCO, CXCL14, CCL19, and PPBP, which are associated with immunity. GO and KEGG analyses were also conducted comparing F1 offspring and their parents. The DEGs, including BPIFB1, HAVCR2, CD163, DDX3X, CCR5, and ITGB3, were enriched in immune-related pathways. Protein-protein interaction (PPI) analysis indicated that the EGFR and ITGA2 genes were key hub genes. In conclusion, this study identifies significant immune DEGs in different pig breeds, providing data to support the exploration of breeding strategies for disease resistance in local and crossbred pig populations.
摘要：
IL-1 beta is an important proinflammatory cytokine with multifaceted modulatory roles in immune responses. In fish, recombinant IL-1 beta has been employed in the control of bacterial diseases, while the antiviral mechanisms of IL-1 beta remain largely unknown, and the efficacy of recombinant IL-1 beta as an immunomodulator to prevent viral diseases is still not determined. This study evaluated the immunomodulatory effects of recombinant grass carp IL-1 beta against grass carp reovirus (GCRV) in vitro and in vivo. Firstly, the mature form (Ser(111)-Lys(270)) of grass carp IL-1 beta was identified, and its recombinant protein (designated as rgcIL-1 beta) was prepared through prokaryotic expression. Then, an in vitro evaluation model for rgcIL-1 beta activity was established in the CIK cells, with the appropriate concentration (600 ng/mL) and effect time (1 h). In vitro, rgcIL-1 beta could not only induce the production of proinflammatory cytokines such as IL-1 beta, IL-6, IL-8, and TNF-alpha but also a series of antiviral factors including IFN1, IFN-2, IFN-gamma, and ISG15. Mechanistically, transcriptome analysis and western blotting confirmed that rgcIL-1 beta activated multiple transcriptional factors, including NF-kappa B, IRF1, IRF3, and IRF8, and the signal pathways associated with inflammatory cytokines and antiviral factors expression. Expectedly, rgcIL-1 beta treatment significantly inhibited GCRV replication in vitro. In vivo administration of rgcIL-1 beta via intraperitoneal pre-injection significantly aroused an antiviral response to restrict GCRV replication and intense tissue inflammation in grass carp, demonstrating the immunomodulatory effects of rgcIL-1 beta. More importantly, rgcIL-1 beta administrated with 10 ng/g and 1 ng/g could improve the survival rate of grass carp during GCRV infection. This study represents the first time to comprehensively reveal the immunomodulatory and antiviral mechanisms of IL-1 beta in fish and may also pave the way for further developing recombinant IL-1 beta as an immunotherapy for the prevention and control of fish viral diseases.

摘要：
Lipid deposition has emerged as a looming challenge worldwide. Previous studies have confirmed the fat-lowering effect of tea polyphenols (TP) in mice, but the underlying mechanism remains elusive. Furthermore, it remains unclear whether TP has the same effect in larger animals. Herein, we simultaneously investigated the regulatory effects of TP on lipid deposition in rats and Ningxiang pigs. The results showed that TP could effectively reduce fat accumulation in rats on a high-fat diet (HFD). As expected, TP supplementation led to a reduction in backfat thickness, fat rate, and subcutaneous fat cell size in Ningxiang pigs. Additionally, TP attenuated gut microbiota dysbiosis by enhancing microbial diversity and increasing the relative abundance of Bacteroides and Akkermansia in both models. Collectively, our results suggest that TP may reduce fat accumulation in rats and Ningxiang pigs by regulating gut microbiota. Therefore, TP could potentially serve as a functional agent for improving fat deposition in humans and Ningxiang pigs.

摘要：
Experimental studies were conducted on the cultivation of tomatoes (Solanum lycopersicum L.) at Shandong Agricultural University, China, from 2022 to 2023. Three cultivation patterns were designed as follows: a north–south orientation with a row spacing of 1.40 m (NS-1.4m), a north–south orientation with a row spacing of 1.80 m (NS-1.8m) and an east–west orientation with a row spacing of 1.80 m (EW-1.8m). A functional–structural plant model using the open source interactive modeling platform of GroIMP was constructed for the cultivation of tomatoes. The growth of plants as well as the light distribution and light interception capacity of the crop canopy were simulated and analyzed. The impacts of these cultivation patterns on the growth, photosynthetic characteristics, fruit ripening time, quality and yield of tomato plants were analyzed. The studies revealed that compared with the NS-1.4m treatment, the canopy light interception of tomato plants under the NS-1.8m and EW-1.8m treatments increased by 6.08% and 9.80% in a winter–spring crop and 6.80% and 19.76% in an autumn–winter crop, respectively. Their plant height, leaf area, aboveground dry matter accumulation, leaf net photosynthesis rate as well as the lycopene, vitamin C and sugar–acid ratio of the fruit all exhibited increasing trends, while fruit ripening was accelerated. The yield of the NS-1.8m and EW-1.8m treatments increased by 3.92% and 6.18% in a winter–spring crop and 4.17% and 9.78% in an autumn–winter crop, respectively. Structural equation modeling was used to further analyze the data, confirming that the cultivation of an east–west orientation with wide row spacing is beneficial for tomato cultivation in Chinese solar greenhouses. This cultivation pattern maximizes the canopy’s light interception, thus leading to improved fruit quality and yield. Overall, this study provides valuable insights for optimizing the cultivation pattern of solar greenhouse crops.
摘要：
A gel electrolyte with molecular anchors is synthesized. It reduces the activity of H2O by anchoring them through ternary hydrogen bonds, which effectively inhibits hydrogen evolution reaction. Furthermore, multiple charged groups of the gel electrolyte induce the deposition of Zn2+ in an orderly manner and promote the directional deposition of Zn2+ on the Zn (002) plane, obtaining a highly reversible dendrite‐free anode. Abstract The high activity of water molecules results in a series of awful parasitic reaction, which seriously impede the development of aqueous zinc batteries. Herein, a new gel electrolyte with multiple molecular anchors is designed by employing natural biomaterials from chitosan and chlorophyll derivative. The gel electrolyte firmly anchors water molecules by ternary hydrogen bonding to reduce the activity of water molecules and inhibit hydrogen evolution reaction. Meanwhile, the multipolar charged functional groups realize the gradient induction and redistribution of Zn2+, which drives oriented Zn (002) plane deposition of Zn2+ and then achieves uniform Zn deposition and dendrite‐free anode. As a result, it endows the Zn||Zn cell with over 1700 h stripping/plating processes and a high efficiency of 99.4% for the Zn||Cu cell. In addition, the Zn||V2O5 full cells also exhibit capacity retention of 81.7% after 600 cycles at 0.5 A g−1 and excellent long‐term stability over 1600 cycles at 2 A g−1, and the flexible pouch cells can provide stable power for light‐emitting diodes even after repeated bending. The gel electrolyte strategy provides a reference for reversible zinc anode and flexible wearable devices.
摘要：
Root-knot nematodes (Meloidogyne spp.) are highly destructive pests that cause enormous crop losses worldwide. With the increasing awareness of environmental protection, exploring the potential of biocontrol agents has become crucial for nematode management. Priestia megaterium YB-3 was originally isolated from rice rhizosphere soil. In vitro experiments with the fermentation supernatant of YB-3 exhibited up to 96.0% mortality of M. graminicola second-stage juveniles (J2) and 39.2% egg hatching inhibition rate at 48 h after treatment. In greenhouse and field experiments, the application of YB-3 significantly suppressed the gall index, final nematode and egg populations compared to the untreated control, while it promoted rice (Oryza sativa) growth. YB-3 showed consistently high biocontrol efficacy against M. graminicola. Moreover, YB-3 remarkably enhanced the expression of defence genes involved in salicylic acid (OsNPR1, OsWRKY45, OsPR1a), jasmonic acid (OsJaMYB, OsAOS2) and ethylene (OsACS1) signalling pathways at different levels. In addition, YB-3 steadily colonized rice rhizosphere soil at levels ranging from 3.54 x 103 to 9.08 x 104 cfu/g soil. High-throughput sequencing analysis showed that the application of YB-3 had no significant influence on the rice rhizosphere microbial community structure, and the taxa enriched in the YB-3 treatment were Acidobacteria, Bacteroidetes and Ascomycota. YB-3 effectively suppressed M. graminicola infection, possibly because it colonized the rice rhizosphere, induced plant resistance and increased the relative abundances of beneficial microorganisms. Priestia megaterium YB-3 could be a promising and safe biological component in the integrated management of M. graminicola.
摘要：
Remediation of arsenic contamination is of great importance given the high toxicity and easy mobility of arsenic species in water and soil. This work reports a new and stable adsorbent for efficient elimination of arsenic by coating polyethyleneimine (PEI) molecules onto the surface of iron-doped birnessite (Fe-Bir). Characterization results of surface microstructure and crystalline feature (scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR) and X-ray photoelectron spectroscopy (XPS), etc.) suggest that Fe-Bir/PEI possesses a fine particle structure, inhibiting the agglomeration of birnessite-typed MnO(2) and offering abundant active sites for arsenic adsorption. Fe-Bir/PEI is capable of working in a wide pH range from 3 to 11, with an efficient removal capacity of 53.86mg/g at initial pH (pH(0)) of 7. Meanwhile, commonly coexisting anions (NO(3-), SO(4)(2-), and Cl(-)) and cations (Na(+), K(+), Ca(2+) and Mg(2+)) pose no effect on the arsenic removal performance of Bir/PEI. Fe-Bir/PEI exhibits a good reusability for arsenic removal with low Mn and Fe ions leaching after 5 cycles. Besides, Fe-Bir/PEI possesses efficient remediation capability in simulated As-contaminated soil. The modification of PEI in Fe-Bir/PEI can adsorb newly formed As(V), which is impossible for the adsorbent without PEI. Further, the arsenic removal mechanism of Fe-Bir/PEI is revealed with redox effect, electrostatic attraction and hydrogen bonding.

摘要：
An aqueous rechargeable Al‐ion battery (ARAIB) using a cubic phase cobalt hexacyanoferrate as positive electrode shows excellent rate and cycling performance together with an average discharge voltage of 1.56 V and an energy density of 155 Wh kg−1. Abstract Like other aqueous batteries, aqueous rechargeable Al‐ion batteries (ARAIBs) have attracted much attention due to their high safety and low cost. However, the low energy density of ARAIBs limits its popularization and application. In order to solve this problem, in addition to choosing Al metal as the negative electrode, it is also necessary to choose a suitable positive electrode material. Here, a cubic phase cobalt hexacyanoferrate (CoHCF) with excellent rate and cycling performance is used as the positive electrode material. Due to the reversible catalysis of the Cl−/Cl0 reaction at high potential in saturated AlCl3 solution, it has the characteristics of high capacity up to 103.5 mAh g−1. Combined with the Al metal as negative electrode, an ARAIB with an average discharge voltage of 1.56 V and an energy density of 155 Wh kg−1 is constructed, which shows outstanding cycling and rate performances.

摘要：
BACKGROUND: Tobacco mosaic virus (TMV) is one famous plant virus responsible for substantial economic losses worldwide. However, the roles of bacterial communities in response to TMV in the tobacco rhizosphere remain unclear. METHODS: We explored the soil physicochemical properties and bacterial community succession of the healthy (YTH) and diseased (YTD) plants with TMV infection by 16S rRNA gene sequencing and bioinformatics analysis. RESULTS: We found that soil pH in the YTD group was significantly lower than in the YTH group, and the soil available nutrients were substantially higher. The bacterial community analysis found that the diversity and structure significantly differed post-TMV disease onset. With TMV inoculated, the alpha diversity of the bacterial community in the YTD was markedly higher than that in the YTH group at the early stage. However, the alpha diversity in the YTD group subsequently decreased to lower than in the YTH group. The early bacterial structure of healthy plants exhibited higher susceptibility to TMV infection, whereas, in the subsequent stages, there was an enrichment of beneficial bacterial (e.g., Ramlibacter, Sphingomonas, Streptomyces, and Niastella) and enhanced energy metabolism and nucleotide metabolism in bacteria. CONCLUSION: The initial soil bacterial community exhibited susceptibility to TMV infection, which might contribute to strengthening resistance of Tobacco to TMV.

biomass hot air furnace;adaptive fuzzy PID;temperature control;simulink simulation
摘要：
Timely and effective drying of agricultural products is crucial for ensuring the quality and yield of grains. Biomass drying enhances energy utilization and reduces energy pressure. To this end, a novel multi-channel circulating biomass hot air furnace was designed to provide precise control of the heat source for grain drying, thereby improving the efficiency and quality of the drying process. The combustion process utilizes a multi-channel combined air supply to ensure complete combustion of biomass pellet fuel. During the heat exchange process, heat exchange plates isolate hot and cold areas, discharging combustion exhaust, while ensuring a pure air output. Using rapeseed as the drying subject, a temperature controller based on adaptive fuzzy PID was designed, targeting the biomass hot air furnace’s heat exchange system for modeling and verifying the model with the step response method. Model simulations were conducted in Matlab’s Simulink module using both adaptive fuzzy PID and traditional PID controllers, for a given signal. The settling times for the conventional PID and fuzzy PID were 445 s and 364 s, respectively, with overshoots of 20.1% and 6.3%, showing that the fuzzy PID controller performed better in terms of control performance. The validation tests showed that both control methods could maintain the temperature within ±5 °C. Compared to traditional PID control, the adaptive fuzzy PID control achieved a precision of ±3 °C. At the target temperature of 90 °C, the error was reduced to 3.7%, with a stabilization time of 1014 s. The use of fuzzy PID control exhibited better dynamic response characteristics, meeting the drying needs of rapeseed. This study provides a theoretical basis for the structural design and control system design of biomass hot air furnaces.
