LI Huiqiang;XIAO Fuxing;WANG Lulu;NENG Furong;WEI Yihao;JIAO Hao;ZHANG Xi;DU Zhen;WANG Xiaochun;

【Objective】To identify and analyze expression characteristics of NIN-like protein(NLP) in wheat with different nitrogen use efficiency(NUE), and provide a theoretical basis for improving nitrogen use efficiency in wheat.【Method】 The conserved RWP-RK and PB1 domains of NLPs were used to identify wheat NLP using the WheatOmics 1.0 database, and the chromosome distribution and evolutionary relationship of TaNLP were analyzed by bioinformatics software.Transcriptomic data from the high-NUE cultivar Zhoumai27(ZM27) and low-NUE cultivar Aikang58(AK58) wheat under reduced nitrogen(120 kg·hm^-2, N8) and normal nitrogen(225 kg·hm^-2, N15) conditions were used to analyze the expression characteristics of TaNLP gene family at the jointing stage.【Result】 A total of 18 TaNLP genes were identified in wheat, unevenly distributed on the chromosomes A, B and D, and divided into four subfamilies according to evolutionary analysis.Most of TaNLP were located in the nucleus.There was no significant difference in the expression of TaNLP in leaves of different NUE cultivars under different nitrogen treatments, whereas distinct expression patterns were detected in roots.TaNLP6D was specifically expressed in the roots of ZM27 under normal nitrogen conditions, while TaNLP4B.2, TaNLP5A2 and TaNLP5D were specifically expressed in the roots of AK58 under reduced nitrogen conditions.The expression levels of TaNLP3A and TaNLP3D were higher in the roots of the ZM27 and AK58 under nitrogen reduction conditions.TaNLP2A and TaNLP2D were positively regulated by nitrogen levels in the roots of ZM27, but the opposite expression was shown in the roots of AK58.【Conclusion】 There were significant differences in root expression among NLP family members of different nitrogen-efficient wheat varieties, and their expression were affected by nitrogen application, indicating these genes play an important role in regulating root nitrogen uptake at wheat seedling stage.

Advances in the study of high use efficiency on phosphorus in cereals and legumes intercropping systems

ZHANG Yinjie;GENG Sainan;YU Xiaona;LI Lantao;ZHANG Qian;WANG Yilun;

Based on a theoretical analysis of the biological differences in phosphorus uptake between cereal and legume crops and the principles of intercropping， this review focuses on how cereal and legume intercropping systems achieve complementary niche advantages and promote efficient phosphorus uptake and utilization. This is accomplished through a crop-microorganism-soil interaction network involving mechanisms such as light regulation， spatial niche differentiation mediated by root architecture， soil phosphorus mobilization mediated by root exudates， root-microorganism symbiosis， rhizosphere microbial regulation， and soil structure optimization. Furthermore， future research directions to enhance the potential of cereal/legume intercropping systems for reducing phosphorus input and increasing use efficiency are discussed. These prospects are considered from the perspectives of mining key genes and signaling pathways for efficient phosphorus regulation using multi-omics technologies， as well as constructing synthetic functional microbial communities and optimizing their colonization techniques.

SUN Chaoxiang;YUAN Liuzheng;LIU Hailin;ZHAO Bin;WANG Dezhe;ZHU Chenhui;LI Lianhao;YANG Shaoqi;XIAO Yatao;

【Objective】This study aims to design an automated， small-scale crawler-type micro-sprinkler tape laying and retrieval device to address the current issues of low automation levels and high labor input associated with existing micro-sprinkler tape laying and retrieval equipment.【Methodology】By conducting an in-depth analysis of practical operational requirements， a small-scale crawler-type mobile chassis and a micro-sprinkler tape laying and retrieval mechanism were designed. Basic parameters， including ground contact pressure， track pitch， and the required power for travel and reeling， were determined. Prototypes of the load-bearing wheel system， guide wheel system， and reeling roller system were fabricated using 3D printing technology with acrylonitrile-butadiene-styrene (ABS) copolymer as the raw material. ANSYS software was employed， in conjunction with actual operational conditions， to verify the strength of the designed components. Additionally， the motion process during micro-sprinkler tape retrieval was analyzed using SolidWorks Motion. A control system integrating remote control， autonomous navigation， and real-time monitoring functions was developed using an STM32 microcontroller combined with remote control modules， ultrasonic modules， and navigation modules.【Results】The strength of the components met the design requirements， and the prototype exhibited good structural integrity. It demonstrated excellent traversability over furrows， gentle slopes， and steps. The maximum actual travel speed achieved was 5.334 km·h?1， with an average deviation rate of 2.984% over a 50 m distance on firm ground. The micro-sprinkler tape laying and retrieval process proceeded smoothly， and all components of the control system operated stably， with a maximum navigation error of 1.87 m.【Conclusion】The equipment integrates remote control， autonomous navigation， and real-time monitoring functions into one unit， meeting the needs for automated laying and retrieval of micro-sprinkler tape in farmland environments.

Preparation and safety evaluation of a novel nano-lyophilized powder for rafoxanide， a veterinary antiparasitic drug

ZHANG Haoze;HAO Zhenxin;ZHANG Chaojun;YI Kaifang;HE Kun;MA Xiaoyuan;HU Gongzheng;YUAN Li;

【Objective】To improve the insolubility of the veterinary drug rafoxanide (RFN) in water， and to enhance its application effectiveness and operational convenience in intensive farming systems.【Method】First， novel rafoxanide nanoparticles (RFN-NPs) were prepared using monomethoxy polyethylene glycol–polylactic acid–glycolic acid copolymer (mPEG-PLGA) as the carrier. Using particle size， polydispersity index (PDI)， encapsulation efficiency， and drug loading capacity as evaluation indicators， the effects of the organic solvent volume ratio (acetone/dichloromethane)， polyvinyl alcohol (PVA) mass fraction， oil-to-water phase volume ratio， carrier mass fraction， and RFN mass were investigated through single-factor experiments. Combined with response surface methodology， the preparation process of the novel RFN-NPs was optimized. Subsequently， lyophilization technology was applied to convert the nanoparticles into a nano lyophilized powder (hereinafter referred to as the lyophilized powder). The lyophilized powder was then characterized and evaluated for safety. Morphological and structural characterization was performed using techniques such as particle size analysis， transmission electron microscopy (TEM)， Fourier transform infrared spectroscopy (FTIR)， and X-ray diffraction (XRD). Stability was characterized through in vitro release tests and stability studies. Safety evaluation was conducted both in vitro and in vivo， including biochemical parameter analysis， histopathological examination， and hemolysis assays.【Result】The optimized RFN-NPs had a particle size of 256.6 nm， a polydispersity index of 0.082， an encapsulation efficiency of 96.48%， and a drug loading capacity of 17.07%. After lyophilization， the reconstituted lyophilized powder exhibited high dispersion and a distinct Tyndall effect. The prepared lyophilized powder appeared fluffy with a granular texture. Transmission electron microscopy (TEM) revealed that the particles of the lyophilized powder displayed a relatively regular spherical structure with smooth edges and no significant agglomeration. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) confirmed that RFN was successfully encapsulated into the carrier and had integrated with the carrier material. In vitro， the lyophilized powder released the drug slowly under different pH conditions. The fastest release rate was observed in a medium with a pH of 6.8， where the cumulative release reached 44.17% at 72 hours. After storage at 4℃ or 25℃ for 30 days， the reconstituted lyophilized powder showed no significant changes in particle size or PDI， indicating good stability. The lyophilized powder was administered intraperitoneally to mice at doses of 20， 40， and 80 mg·kg?1 once daily for 7 consecutive days. Necropsy results showed that the morphological structures and histopathological sections of organs such as the heart， liver， spleen， lungs， and kidneys in all dose groups showed no significant differences compared to the negative control group. Biochemical indicators further confirmed no significant alterations in liver or kidney function. Additionally， the lyophilized powder did not induce hemolysis of red blood cells.【Conclusion】The new RFN-NPs and their nano lyophilized powder were successfully prepared. The lyophilized powder exhibits the advantages of uniform particle size， high stability， no hemolytic effect on red blood cells， and excellent safety.

Identification and Functional Characterization of the RNA Silencing Suppressor FpPLA in Fusarium pseudograminearum

QIN Cancan;YU Miao;WANG Zhifang;WANG Limin;WANG Min;LI Honglian;DING Shengli;LI Haiyang;

【Objective】This study identified potential RNA silencing suppressors and elucidated their functions in the pathogenicity of Fusarium pseudograminearum， thereby uncovering molecular mechanisms underlying the interaction between this pathogen and host.【Methods】Potential RNA silencing suppressors were screened by co-expressing candidate effectors with GFP (Green Fluorescent Protein) in 16C transgenic tobacco. Their protein structures were analyzed using bioinformatics approaches， and the secretory function of their signal peptides was validated through a yeast secretion system. The impact of the RNA silencing suppressor on inhibiting pathogen infection was assessed by inoculating pathogens onto tobacco leaves expressing the candidate effector. Additionally， the pathogenicity of knockout mutants was determined after deleting the FpPLA gene via homologous recombination. 【Results】First， strong green fluorescence signals were exclusively detected in 16C tobacco leaves co-infiltrated with FpPLA (F. pseudograminearum Phospholipase A) and GFP gene， indicating that the expression of FpPLA suppresses the plant's RNA silencing pathway. Second， it was experimentally confirmed that FpPLA is a secretory protein， and its expression in plants can inhibit plant pathogen infection. Finally， the knockout of the FpPLA gene did not significantly affect virulence on wheat coleoptiles compared to the wild-type strain WZ-8A. 【Conclusion】 During the infection of wheat by F. pseudograminearum， the effector protein FpPLA is secreted into plant cells. It inhibits the plant RNA silencing pathway， thereby suppressing the pathogen infection process. However， knocking out a single FpPLA gene has no impact on the pathogenicity of F. pseudograminearum.
