Science》上。这是该团队继在国际首次解析十字花科作物感病基因介导的根肿病隐性广谱抗性后，在十字花科作物根肿病研究领域取得的又一突破性进展。\n\n根肿病是危害油菜、白菜、甘蓝等十字花科作物的共性重大土传病害，近年来在我国大范围流行，对油料和蔬菜生产造成重大损失。引起根肿病的病原根肿菌是一类具有动物行为的低等单细胞真核生物（原生动物），与已知植物病原物分类不同，其分子基础长期缺乏深入认识。RNAi是真核生物中广泛存在的一种基因调控现象，具有靶向性好、适用性广、环境友好等特点，作用机制多样，已广泛应用于农作物病虫害的抗性改良和绿色高效防控，但根肿菌是否具有RNAi系统、其作用机制如何长期未知。\n\n为此，研究团队聚焦根肿菌分子生物学及其侵染路径开展研究，首次发现了根肿菌中存在一套区别于经典RNAi调控的新模式，且侵染早期的根肿菌含有一种高分子多聚糖几丁质，是油菜根肿病绿色高效防控的理想靶标。研究团队通过RNAi技术干扰根肿菌不同生理小种的几丁质合成，成功阻断了根肿菌的早期侵染，实现了油菜根肿病的广谱抗性改良。上述研究打通了从病原基础机制解析、防控靶点挖掘到抗病材料创制的完整研究链条，丰富了真核生物RNAi机制多样性的理论认知，为十字花科根肿病广谱抗性改良和绿色高效防控提供了新的理论依据和技术路径。\n\n(单位:

Science》上。这是该团队继在国际首次解析十字花科作物感病基因介导的根肿病隐性广谱抗性后，在十字花科作物根肿病研究领域取得的又一突破性进展。\n\n根肿病是危害油菜、白菜、甘蓝等十字花科作物的共性重大土传病害，近年来在我国大范围流行，对油料和蔬菜生产造成重大损失。引起根肿病的病原根肿菌是一类具有动物行为的低等单细胞真核生物（原生动物），与已知植物病原物分类不同，其分子基础长期缺乏深入认识。RNAi是真核生物中广泛存在的一种基因调控现象，具有靶向性好、适用性广、环境友好等特点，作用机制多样，已广泛应用于农作物病虫害的抗性改良和绿色高效防控，但根肿菌是否具有RNAi系统、其作用机制如何长期未知。\n\n为此，研究团队聚焦根肿菌分子生物学及其侵染路径开展研究，首次发现了根肿菌中存在一套区别于经典RNAi调控的新模式，且侵染早期的根肿菌含有一种高分子多聚糖几丁质，是油菜根肿病绿色高效防控的理想靶标。研究团队通过RNAi技术干扰根肿菌不同生理小种的几丁质合成，成功阻断了根肿菌的早期侵染，实现了油菜根肿病的广谱抗性改良。上述研究打通了从病原基础机制解析、防控靶点挖掘到抗病材料创制的完整研究链条，丰富了真核生物RNAi机制多样性的理论认知，为十字花科根肿病广谱抗性改良和绿色高效防控提供了新的理论依据和技术路径。\n\n(单位:

The crop is predominantly grown in states such as West Bengal, Uttar Pradesh, Gujarat, Madhya Pradesh, and Rajasthan, which contribute substantially to national production. Over the years, the acreage under sesamum has gradually contracted, reflecting changes in cropping patterns and production conditions; however, advances in yield performance have helped maintain production levels. An assessment of long-term production trends and market dynamics is crucial for designing strategies that support sustainable crop diversification, strengthen farmers’ livelihoods, and improve market efficiency through enhanced price transmission and integration across regions. Methods This study analyzed the long-term performance of sesamum cultivation in India by examining changes in area, production, and productivity over the period 1980–81 to 2025–26. Wholesale price data from major sesamum-producing states were also utilized to investigate price movements and the extent of market integration. Growth performance and production dynamics were assessed using techniques such as Compound Annual Growth Rate (CAGR), decomposition analysis, instability measures, seasonal indices, and correlation analysis. To examine the nature of price relationships across markets, econometric tools including the Augmented Dickey–Fuller (ADF) unit root test, Johansen co-integration test, Granger causality analysis, Vector Error Correction Model (VECM), impulse response analysis, and forecast error variance decomposition were employed. These methods facilitated an evaluation of both short-run and long-run price transmission mechanisms within the Indian sesamum market. Results The study revealed that the expansion of sesamum production in India has largely resulted from gains in crop productivity, even though the area under cultivation has shown a declining trend over time. Measures of instability indicated noticeable variations in cultivated area, output, and market prices across the major producing states. Seasonal analysis demonstrated clear price movements, with lower prices during harvest and peak market arrivals and higher prices during periods of limited supply. The presence of strong market linkages was confirmed through high correlations, significant long-run co-integration, and effective price transmission among markets. Causality analysis identified Gujarat, Rajasthan, and Telangana as key markets influencing price movements in other regions. Trade performance showed that India continues to hold an important position in global sesamum exports, while imports have also risen due to increasing domestic demand and periodic supply shortages. These findings emphasize the need to improve productivity, strengthen market integration, and enhance trade competitiveness to support the long-term development of the sesamum sector. Conclusion Sustainable growth of the sesamum sector requires a strategic focus on enhancing productivity through the development and dissemination of improved, climate-resilient cultivars suited to diverse agro-ecological conditions. Strengthening post-harvest infrastructure, including storage, processing, and transportation facilities, will help minimize losses and improve product quality. Efficient market information services, wider adoption of digital marketing platforms such as e-NAM, and better market integration can enhance transparency and ensure remunerative prices for farmers. In view of the expanding domestic and international demand for sesame and value-added products, greater attention should be given to export promotion and value-chain strengthening. Furthermore, encouraging sesamum cultivation in rainfed and resource-constrained regions through appropriate policy support and market incentives can foster crop diversification, improve farm profitability, and contribute to sustainable agricultural development.","背景 芝麻（Sesamum indicum L.）是最古老的栽培油料作物之一，因其含油量丰富、营养价值高且适应多种农业气候环境，在印度农业中占有重要地位。该作物主要种植于西孟加拉邦、北方邦、古吉拉特邦、中央邦和拉贾斯坦邦等地区，这些地区对全国产量贡献显著。多年来，芝麻种植面积逐渐缩减，反映了种植模式和生产条件的变化；然而，单产水平的提高有助于维持产量水平。评估长期生产趋势和市场动态对于制定支持可持续作物多样化、增强农民生计以及通过改善价格传导和跨区域市场整合提高市场效率的策略至关重要。方法 本研究通过考察1980-81年至2025-26年期间面积、产量和生产率的变化，分析了印度芝麻种植的长期表现。同时利用芝麻主产区的批发价格数据，研究了价格变动和市场整合程度。采用复合年增长率（CAGR）、分解分析、不稳定性测度、季节指数和相关性分析等方法评估增长表现和生产动态。为考察市场间价格关系的性质，采用了增广迪基-富勒（ADF）单位根检验、约翰森协整检验、格兰杰因果分析、向量误差修正模型（VECM）、脉冲响应分析和预测误差方差分解等计量经济学工具。这些方法有助于评估印度芝麻市场中的短期和长期价格传导机制。结果 研究表明，印度芝麻产量的增长主要源于作物生产率的提高，尽管种植面积随时间呈下降趋势。不稳定性测度表明，各主产区的种植面积、产量和市场价格存在明显波动。季节性分析显示价格变动明显，收获期和市场到货高峰期价格较低，供应有限时期价格较高。通过高相关性确认了市场间存在较强的联动关系，显著……","Frontiers in Sustainable Food Systems","2026-10-14T00:00:00Z","论文",76,{"impact":19,"substance":274,"depth":222,"authority":275,"freshness":276,"relevant":22,"comment":277},21,13,9,"基于1980-2025年长序列数据对印度芝麻产销与市场整合的实证研究，方法扎实、结论可靠，对我国油料作物市场监测与数字营销平台建设有借鉴价值。",[279],{"name":269,"url":266},[29,281,282,283,284],"农产品市场","芝麻产业","价格传导","e-NAM",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":288},{"candidates":289,"agricultural_evidence":47},[290],{"code":33,"score":114,"supported":47,"title":291,"abstract":292,"tags":294},[],[293],"芝麻",[],[296,297],"印度 芝麻 市场整合","印度 芝麻 出口","印度芝麻市场整合-4981","10.3389\u002Ffsufs.2026.1938242",{"doi":299,"openalex_id":301,"authors":302,"venue":269,"cited_by_count":209,"oa_url":266,"card":311,"direction":315,"ingested_from":317},"W7221827064",[303,305,307,309],{"name":304,"orcid":8},"Ramalingareddy Vijaya Kumari",{"name":306,"orcid":8},"SREENIVAS AKULA",{"name":308,"orcid":8},"Ramakrishna Gundu",{"name":310,"orcid":8},"VENKATESH PANASA",{"tldr":312,"method":313,"finding":314,"direction":315,"opportunity":316},"分析印度芝麻1980-2025年生产动态、价格波动与主要产区市场整合关系。","CAGR、分解分析、ADF、协整、Granger因果、VECM等时间序列方法。","产量增长主要靠单产提升而非面积扩张，各主产州市场间存在显著长期价格联动。","农业人工智能与决策模型","可将价格传导与市场整合模型扩展到气候、政策变量，构建农产品市场预警与决策支持系统。","openalex","2026-10-15T23:30:06.727107Z",{"id":320,"title":321,"url":322,"summary":323,"summary_zh":324,"content":8,"source_name":325,"source_url":322,"published_at":326,"category":271,"cover_url":8,"hotness":13,"is_selected":14,"score":327,"score_detail":328,"sources":330,"tags":332,"primary_topic":337,"secondary_topics":338,"classification":339,"search_phrases":356,"slug":359,"view_count":209,"doi":360,"paper":361,"created_at":381},3983,"Numerical and experimental investigation on the cutting mechanism of rapeseed stalk using abrasive gas jet based on SPH-FEM coupling","https:\u002F\u002Fdoi.org\u002F10.1016\u002Fj.compag.2026.112469","Numerical and experimental investigation on the cutting mechanism of rapeseed stalk using abrasive gas jet based on SPH-FEM coupling。Computers and Electronics in Agriculture","基于SPH-FEM耦合的磨料气体射流油菜茎秆切割机理数值与实验研究。《计算机与电子农业》","Computers and Electronics in Agriculture","2026-10-01T00:00:00Z",72,{"impact":46,"substance":221,"depth":222,"authority":223,"freshness":276,"relevant":22,"comment":329},"核心期刊论文，SPH-FEM耦合方法研究油菜秸秆磨料气体射流切割机理，方法有新意但属细分领域基础研究，产业影响有限。",[331],{"name":325,"url":322},[333,28,334,335,336],"智慧农业","数值模拟","农业机械","秸秆处理",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":340},{"candidates":341,"agricultural_evidence":47},[342,347,351],{"code":33,"score":20,"supported":47,"title":343,"abstract":345,"tags":346},[344],"rapeseed",[28,344],[28],{"code":201,"score":22,"supported":14,"title":348,"abstract":349,"tags":350},[],[],[335],{"code":352,"score":22,"supported":14,"title":353,"abstract":354,"tags":355},"I1",[],[],[333],[357,358],"油菜秸秆 磨料气体射流 切割","SPH-FEM 耦合 秸秆切割","油菜秸秆磨料气体射流切割-3983","10.1016\u002Fj.compag.2026.112469",{"doi":360,"openalex_id":362,"authors":363,"venue":325,"cited_by_count":209,"oa_url":8,"card":376,"direction":315,"ingested_from":317},"W7215128671",[364,367,369,371,373],{"name":365,"orcid":366},"Mun-Sung Han","https:\u002F\u002Forcid.org\u002F0009-0000-4043-6982",{"name":368,"orcid":8},"Xiaokang Qin",{"name":370,"orcid":8},"Kai Yu",{"name":372,"orcid":8},"Yun Chen",{"name":374,"orcid":375},"Kaixiong Hu","https:\u002F\u002Forcid.org\u002F0000-0001-9904-6137",{"tldr":377,"method":378,"finding":379,"direction":315,"opportunity":380},"采用SPH-FEM耦合方法数值与实验研究磨料气体射流切割油菜茎秆的机理。","SPH-FEM耦合数值模拟结合切割实验，分析磨料气体射流切割过程。","揭示了磨料气体射流切割油菜茎秆的力学机制与切割参数影响规律。","可将SPH-FEM耦合仿真拓展至其他作物茎秆切割，并融合机器视觉实现切割参数智能优化。","2026-10-02T23:30:03.593073Z"]
