sinensis）作为全球重要的多年生经济作物，其生产常受炭疽病等真菌病害的严重威胁。植物激素信号网络是介导茶树抵御病原侵染的核心机制，其中水杨酸（SA）、生长素（IAA）和茉莉酸（JA）在防御响应中发挥关键作用。然而，这些激素常以无活性的甲基化形式（如MeSA、MeIAA、MeJA）储存，其向活性形式的转化依赖于特定的甲基酯酶（Methyl Esterase, MES）催化。近期，浙江省农业科学院茶树种质创新与利用团队在国际权威期刊《Journal of Agricultural and Food Chemistry (JAFC)》（农林科学一区TOP期刊）发表题为“Functional Characterization of the Methyl Esterase MES4 in Hydrolytic Activity of Methylated Phytohormones in Tea Plants Based on Multi-Omics Analysis”的研究论文，系统解析了茶树MES基因家族的功能，并首次鉴定了一个具有三重底物特异性的关键酶——CsMES4。\n\n研究团队基于茶树致病菌Colletotrichum camelliae侵染茶树叶的转录组与植物激素代谢组联合分析，筛选出与激素动态变化高度相关的候选基因。通过全基因组鉴定，共获得17个CsMES成员。其中，CsMES4在病原侵染后显著上调表达，且亚细胞定位显示其定位于细胞核与细胞膜，提示其可能参与信号感知与转导。后续通过原核表达、蛋白纯化及体外酶活测定，研究证实CsMES4能高效催化MeSA、MeIAA和MeJA的去甲基化反应，分别生成活性形式的SA、IAA和JA。为进一步验证其生物学功能，研究采用反义寡核苷酸（asODN）技术在茶树叶片中实现CsMES4的瞬时沉默。结果表明，CsMES4沉默显著降低了叶片中SA、IAA和JA的积累水平，并导致炭疽病病斑面积显著扩大，直接证明CsMES4正向调控茶树对炭疽病的抗性。为阐明CsMES4多功能催化的结构基础，研究团队构建了其三维结构模型，并结合分子对接预测潜在底物结合位点。随后，针对非保守但邻近活性中心的氨基酸残基（F60、S127、L128）进行定点突变。功能分析显示：F60L突变显著削弱了酶对三种底物的催化活性；S127Y突变则增强了其催化效率。上述结果不仅明确了CsMES4催化功能的关键决定位点，也为理解其广谱底物特异性的分子基础提供了结构依据。\n\n本研究系统鉴定了茶树MES基因家族，并功能验证了CsMES4作为连接甲基化激素前体与活性防御信号的核心枢纽。该成果不仅深化了对茶树激素代谢与免疫调控网络的认识，也为茶树抗病分子设计育种提供了高价值的候选基因资源。未来通过遗传改良提升CsMES4的表达或活性，有望培育出对炭疽病等主要病害具有持久抗性的新种质，助力绿色、可持续茶产业发展。\n\n本研究由浙江省农业科学院蚕桑与茶叶研究所李达助理研究员为第一作者，浙江农林大学汪瑛琦博士为第二作者，浙江省农业科学院李清声副研究员为通讯作者。工作得到国家自然科学基金项目及浙江省农业茶树新品种选育重大科技专项等项目的资助。","浙江省农业科学院\u002FJAFC

scientific research article \u002F Preprint Description This scientific article presents a comparative evaluation of five coffee cooperative organizations in Oromia, Ethiopia: Chercher Oda Bultum Farmers Cooperative Union, Homa Multipurpose Farmers Cooperative, Kata Muduga Multipurpose Farmers Cooperative Union, Torban Anfillo Multipurpose Farmers Cooperative Union, and Sadetan Chora Farmers Cooperative Union. The research investigates variability in biological production, institutional organization, processing efficiency, digital traceability, product quality, market participation and financial value realization. The study uses institutional questionnaires, cooperative administrative records and previously developed case assessments, supported by recent international, African and Ethiopian scientific literature. Its integrated analytical framework comprises 18 end-to-end value-chain components, nine value-creation and conversion gates, three institutional levels and the eight-stage Big Win methodology. The comparative results demonstrate significant differences in organizational scale, coffee-growing ecology, farmer registration, geospatial mapping, production measurement, processing infrastructure, quality assurance, certification, export-market participation, financial settlement and digital readiness. The findings also identify common weaknesses in upstream traceability, data consistency, coffee-lot genealogy, processing mass balance, producer-level quality differentiation and verifiable links between commercial transactions and farmer payments. The scientific discussion examines how biological productivity, environmental sustainability, quality conservation, processing efficiency, value addition, buyer acceptance, and realized commercial value depend on reliable institutional coordination and information exchange. The analysis draws on recent research concerning digitalization and sustainability (Hidalgo et al., 2023), Ethiopian coffee traceability and buyer trust (Mbakop et al., 2023), digital traceability capabilities (Tadesse et al., 2024), geographical-origin compliance (Urugo et al., 2025), Ethiopian coffee-quality differentiation (Worku, Astatkie, and Boeckx, 2023), and sustainability performance in southwestern Oromia (Botola, Werke, and Birbirsa, 2026). International institutional frameworks from the International Coffee Organization, UNIDO, FAO, GS1, and ISO inform the proposed approaches to value-chain resilience, circular resource management, digital interoperability, and product traceability. The article proposes an integrated Smart Digital Coffee Value Chain architecture linking market intelligence, genetic resources, nursery development, producer and plot identity, extension services, production, harvesting, aggregation, processing, quality assurance, storage, certification, market contracts, buyer acceptance, financial settlement and feedback. A five-year scientific transformation proposal identifies differentiated improvement priorities for each organization, together with harmonized Business Requirements (BR), Functional Requirements (FR), institutional data dependencies, Key Performance Indicators (KPIs), Key Risk Indicators (KRIs) and corrective and preventive actions. The principal scientific contribution is a comparative framework demonstrating how cooperative organizations with different ecological, institutional, and commercial characteristics can implement a common, interoperable digital value-chain system while following locally appropriate transformation pathways. The study contributes to scientific understanding of cooperative value-chain performance, digital agriculture, institutional coordination, biological and economic efficiency, environmental sustainability and commercial value realization. The findings are based principally on documentary and organizational evidence. Reported performance indicators are distinguished from calculated measures and proposed interventions. Differences in reporting periods, measurement units and data completeness limit direct statistical comparability, while the proposed five-year improvements require implementation and independent evaluation.

The manual translates institutional assessment findings, scientific knowledge, digital-system requirements, and value-chain management principles into operational procedures suitable for cooperative organizations and other agricultural value-chain institutions. The manual draws on the Union's institutional questionnaire completed on 7 October 2026 and relevant scientific publications on international, African, and Ethiopian coffee production, processing, traceability, sustainability, and cooperative development. Its integrated methodological structure consists of 18 end-to-end coffee value-chain components, nine value-creation and conversion points, three institutional levels, and eight stages of the Big Win delivery methodology. The institutional baseline includes 28,164 members, 61,270 hectares of coffee-growing land, 49,287 productive hectares, an annual production of 315,337 quintals, 62 washing and collection facilities, 5,127 GPS-mapped farms, and reported direct-export experience. The manual evaluates these existing institutional capacities and identifies priority gaps in farmer-level digital identification, planting-material genealogy, production information, product traceability, processing utilization, quality testing, environmental compliance, market contracts, payment verification, and coordinated performance management. It establishes differentiated responsibilities for three institutional levels: Core value-chain actors: Farmers, primary cooperatives, cooperative unions, processors, exporters, and buyers responsible for biological production, collection, processing, commercial transactions, and payment. Supporting institutions: Research centers, agricultural extension services, financial institutions, quality laboratories, logistics providers, and digital technology organizations responsible for specialized technical and operational services. Policy and enabling institutions: The Oromia Cooperative Promotion Commission, agricultural and trade bureaus, regulatory organizations, and regional and national governments responsible for governance, standards, policy coordination, and enabling infrastructure. The manual specifies practical Business Requirements (BR), Functional Requirements (FR), data ownership, information exposing and consuming relationships, interoperable digital identification, transaction records, quality assurance, institutional accountability, and measurable performance indicators. Recent international and African experiences are incorporated to identify transferable best practices in cooperative modernization, agricultural digitalization, specialty-coffee differentiation, sustainable production, traceability, and circular value creation. The proposed five-year implementation roadmap applies the Big Win methodology through Direction, Mini-Lab, Open Day, Roadmap, KPI\u002FKRI Development, Implementation, Verification, and Annual Performance Reporting. Implementation priorities include reliable farmer and farm registration, verified production data, digital collection receipts, coffee-lot genealogy, quality-preserving processing, transparent market contracts, buyer acceptance, producer-payment reconciliation, and feedback-driven corrective actions. The principal contribution of this manual is a structured and adaptable implementation model for converting agricultural production potential into traceable products, conserved quality, added commercial value, accepted market transactions, and realized producer benefits. The manual is designed for practical application by farmers, cooperatives, cooperative unions, researchers, government organizations, development partners, technology developers, exporters, and investors in Ethiopia, Africa, and other coffee-producing regions.

The study investigates how smallholder coffee production, cooperative aggregation, processing, quality assurance, international marketing, and financial transactions can be integrated into a smart digital coffee value chain that improves traceability, value conservation, economic efficiency, and producer benefits. The research integrates a structured cooperative questionnaire, a farmer-level administrative registry containing 2,000 records, and a comprehensive Business and Functional Requirements Specification (BFRS). The analytical framework comprises 18 end-to-end coffee value-chain components, nine points of value creation (conservation, addition, and conversion), three institutional levels (core value-chain actors, supporting institutions, and the policy environment), and the eight-stage Big Win delivery methodology. The assessment documents 2,000 cooperative members, including 449 women and 204 youth, managing approximately 1,585.2 hectares of coffee production. The cooperative reports annual red-cherry production of 4,968.696 tonnes, while its farmer registry records 4,832.929 tonnes. Reported processing volume is 2,388.254 tonnes of red cherry, equivalent to approximately 477.651 tonnes of green coffee under an indicative 5:1 conversion assumption. Direct green-coffee exports total 264.240 tonnes, with a reported export value of US$2,069,127.329 and an implied export unit value of approximately US$7.83\u002Fkg. The results identify important organizational strengths, including nursery operations, mapped smallholder farms, two washing stations, specialty coffee production, export-market participation, and reported certification activities. However, the analysis reveals weaknesses in planting-material genealogy, reliable source identification, digital transaction continuity, coffee-lot traceability, quality-linked producer payments, data validation, and institutional interoperability. Six farmer-coordinate records require further verification, while discrepancies between questionnaire and registry production figures indicate the need for improved administrative data governance. The scientific discussion compares these findings with recent international, African, and Ethiopian publications on coffee sustainability, digital traceability, geographical differentiation, processing quality, cooperative governance, and market competitiveness. Particular emphasis is placed on the relationship between biological productivity, product quality preservation, processing recovery, buyer acceptance, and realized economic value. The paper proposes an integrated Smart Digital Coffee Value Chain architecture linking market intelligence, research and genetics, nursery systems, farmer and plot identification, agricultural services, production, harvesting, collection, processing, storage, certification, buyer contracts, export acceptance, financial settlement, and performance feedback. It further translates the evaluation into prioritized Business Requirements (BR), Functional Requirements (FR), institutional data-supply and consumption responsibilities, interoperable information flows, corrective and preventive actions (CAPA), and measurable Key Performance and Key Risk Indicators (KPI\u002FKRI). A five-year implementation proposal establishes a phased pathway from baseline reconciliation and digital identity verification to transaction-level traceability, quality conservation, commercial integration, producer-payment transparency, and evidence-based scaling. The principal scientific contribution is a practical and replicable framework for transforming fragmented smallholder coffee activities into an integrated, traceable, and economically accountable value chain. The study demonstrates how biological production, quality conservation, value addition, market conversion, and financial realization can be assessed through connected institutional responsibilities and verifiable digital records. The findings provide useful evidence and implementation guidance for coffee farmers, primary cooperatives, cooperative unions, the Oromia Cooperative Promotion Commission, regional and national government institutions, researchers, exporters, investors, and digital-system developers in Ethiopia and other coffee-producing regions. The reported organizational findings describe the available 2026 baseline, while proposed interventions, performance targets, and anticipated economic benefits require field implementation and independent verification.

In the Eastern Amazon region, this system is used to harvest native fruits such as açaí and cacao. However, different management strategies may be associated with contrasting biochemical and molecular characteristics of these fruits. To evaluate these differences, a comparative observational analysis of açaí pulps and cacao seeds with adhering arils was performed using samples from two neighboring agroforestry systems in Tomé-Açu (Pará, Brazil), with one farm representing an organic management regime (AFS19) and the other representing a conventional management regime (AFS27). The analysis focused on trace element composition, metabolic diversity, and gene expression. The elemental composition of the fruits was broadly similar, although açaí from AFS19 had 35% and 38% higher concentrations of phosphorus and copper, respectively, while cacao from AFS27 had 17%–30% higher concentrations of calcium, manganese, magnesium, and sulfur. The metabolic profiles of both açaí and cacao from AFS19 were more diverse and included several putative compounds, such as apigenin and esculin, tentatively annotated only in samples from AFS19. Transcriptomic data showed that açaí pulps from AFS19 had higher expression of genes associated with antioxidative processes and stress resistance, whereas AFS27 showed higher expression of genes related to ripening, proteolysis, and flavonoid biosynthesis. In cacao seeds, AFS19 showed higher expression of transcripts associated with seed protection and carbohydrate metabolism on reserve mobilization, while AFS27 showed higher expression of genes related to pathogen resistance, seed coating, and maturation. Overall, the combined analysis revealed distinct biochemical and transcriptomic profiles between the two agroforestry systems, providing comparative data on fruit characteristics associated with contrasting management regimes in tropical agroforestry systems.","农林复合经营是一种将生产与可持续性相结合的农业实践。在东亚马逊地区，该系统被用于采收巴西莓（açaí）和可可等本土果实。然而，不同的管理策略可能与该类果实在生化和分子特征上的差异相关。为评估这些差异，本研究对来自巴西帕拉州托梅-阿苏（Tomé-Açu）两个相邻农林复合系统的巴西莓果肉和带假种皮的可可种子进行了比较性观察分析，其中一个农场代表有机管理方式（AFS19），另一个代表常规管理方式（AFS27）。分析聚焦于微量元素组成、代谢多样性和基因表达。果实的元素组成总体相似，但AFS19的巴西莓中磷和铜的浓度分别高出35%和38%，而AFS27的可可中钙、锰、镁和硫的浓度高出17%–30%。AFS19的巴西莓和可可的代谢谱均更为多样，并包含若干推定化合物，如芹菜素（apigenin）和秦皮苷（esculin），这些化合物仅在AFS19样品中被初步注释。转录组数据显示，AFS19的巴西莓果肉中与抗氧化过程和抗逆性相关的基因表达更高，而AFS27中与成熟、蛋白质水解和类黄酮生物合成相关的基因表达更高。在可可种子中，AFS19中与种子保护和碳水化合物代谢（储备动员）相关的转录本表达更高，而AFS27中与病原体抗性、种子包被和成熟相关的基因表达更高。总体而言，联合分析揭示了两类农林复合系统之间不同的生化和转录组谱，为热带农林复合系统中与不同管理方式相关的果实特征提供了比较数据。","Frontiers in Sustainable Food Systems","2026-10-16T00:00:00Z",64,{"impact":151,"substance":18,"depth":325,"authority":326,"freshness":79,"relevant":21,"comment":327},16,13,"该研究对比了亚马逊东部有机与常规管理下巴西莓和可可的生化与转录组差异，方法扎实、数据具体，但属区域性基础研究，公共影响有限，适合作为论文类资讯收录，不进入每日精选。",[329],{"name":321,"url":318},[331,332,333,334,335],"农林复合系统","亚马逊水果","代谢组学","转录组学","有机管理",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":13,"version":39,"method":40,"evidence":339},{"candidates":340,"agricultural_evidence":45},[341],{"code":31,"score":19,"supported":45,"title":342,"abstract":344,"tags":346},[343],"cacao",[345,343],"可可",[],[348,349],"Tomé-Açu 农林复合系统 巴西莓","可可 农林复合系统 转录组","Tomé-Açu农林复合系统巴西莓-5142","10.3389\u002Ffsufs.2026.1970644",{"doi":351,"openalex_id":353,"authors":354,"venue":321,"cited_by_count":188,"oa_url":367,"card":368,"direction":372,"ingested_from":206},"W7222624325",[355,357,359,361,363,365],{"name":356,"orcid":8},"R.
