GacS-mediated regulatory framework coordinates bacterial competition and rhizosphere microbiome remodeling in Pseudomonas fluorescens”为题，发表于微生物学Top期刊《微生物组（Microbiome）》（5年平均影响因子：18.5）。\n\n假单胞菌是可培养细菌第二大属，荧光类假单胞菌是一类典型的植物根际促生菌（Plant Growth-Promoting Rhizobacteria， PGPR），具有拮抗病原菌、诱导植物抗性、促进植物生长、改善植物健康的特征。当前对 PGPR 的研究多聚焦于单个基因的功能，而对这些基因如何协同作用、共同调控环境–微生物–植物的多界面互作缺乏系统认识。本研究系统解析了荧光假单胞菌16个与蛋白分泌、信号调控和抗菌代谢相关的基因，逐一敲除并系统比较了各突变体的运动能力、生物膜形成、植物免疫激发以及土壤和根际微生物群落变化。研究发现，全局调控因子GacS作为“总开关”，协调下游两条关键通路GacS-FliC与GacS-Phl，参与根际微生物群落重塑与细菌竞争。一方面，GacS 通过调控鞭毛蛋白基因 fliC 的表达影响细菌运动能力、调节植物免疫激发、富集德沃斯氏菌（Devosia）等在内的有益菌，重塑根际微生物群落结构。另一方面，GacS通过调控phl合成基因簇，促进抗菌物质2,4-二乙酰基间苯三酚（2,4-DAPG）的产生，直接抑制土壤中另一大有益微生物类群--链霉菌（Streptomyces）的丰度，重塑微生物互作格局。体外验证表明，荧光假单胞菌对链霉菌属具有广谱的抑制能力，且该作用主要依赖GacS-Phl途径。\n\n![Image

近日，中国农业科学院农业资源与农业区划研究所农业微生物资源创新团队揭示了Ⅲ型分泌系统在根际荧光类假单胞菌中的演化机制。相关研究成果发表在《新植物学家（New Phytologist）》上。 Ⅲ型分泌系统历来被认为是植物病原菌的侵染“专用武器”。致病菌为在宿主体内生存、繁殖、扩散，会分泌一些蛋白性质的毒性因子。目前认为革兰阴性致病菌在长期进化过程中形成入侵宿主细胞的特异性分泌系统共有5种类型(Ⅰ～Ⅴ型)，其中最显著的是细菌Ⅲ型分泌系统。然而近年来，在根际有益荧光假单胞菌中也发现了该系统，其来源及功能分化机制尚不清楚。 科研团队从我国15个省（自治区、直辖市）采集114份根际土壤样品，筛选出110株携带Ⅲ型分泌系统基因的菌株，对其中43株进行基因组测序，结合公共数据库已有数据共获得88株Ⅲ型分泌系统阳性菌株基因组数据。 研究发现，这些菌株分属荧光假单胞菌7个亚群，其Ⅲ型分泌系统可划分为6种演化类型，经历了多次独立的基因横向转移，传播和功能分化受生态位适应驱动。功能分析显示，携带该系统的菌株普遍具有植物促生防病功能。 该研究打破了Ⅲ型分泌系统仅为病原菌致病工具的认知，为理解微生物—植物互作中“致病”与“共生”功能分化奠定了理论基础。

insights into root 2-naphtholic acid exudation, microbiome recruitment, and designing of drought-smart future crops","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffpls.2026.1938013","the wider landscape of rhizosphere ecology, chemical signaling, and stress-adaptive sustainable agricultural solutions.In this paper, we provide opinions relevant to the topic and new dimension of research. First, microbial diversity should be treated as an upstream constraint on host chemical signaling rather than as a correlate of plant performance. Second, 2-NA is the best read as a proof of principle for multifunctional exudates, not as a candidate agricultural input. Third, the distance between the mechanism and field deployment is considerably greater than current enthusiasm for microbiome engineering suggests.The novel insights from Chen et al. (2026) demonstrate that drought stressed plants grown with highestdiversity community (D1) accumulated 2-NA at approximately 16.5 μg•mL⁻¹, while intermediate diversity (D2) yielded around 0.27 μg•mL⁻¹, and the lowest diversity soil (D3) yielded none. Because 2-NA was undetectable in well-watered treatment, drought appears to act as the trigger and diversity as the gain control. Integrated transcriptomic and metabolomic profiling linked 2-NA accumulation to phenylpropanoid-related metabolism consistent with broader evidence that community context reshapes plant secondary metabolism under abiotic stress (Li et al.,2025;Kazarina et al., 2025;Yang et al., 2025).Our reading inverts the conventional framing. The \"cry-for-help\" narrative casts the plant as the agent and microbiome as the respondent, suggest the resident community sets the boundaries of what plant can do. Especially, low-diversity rhizospheres showed far broader transcriptional reprogramming than high diversity ones. We interpret this as a metabolic economy, where a diversity community supplies functional insurance, the host can invest narrowly and precisely; where it does not, the plant is pushed towards costly, diffuse and less targeted responses (Yang et al., 2021;Domeignoz-Horta et al., 2024).On this view, diversity is chemical signaling capital.This carries an uncomfortable agronomic implication. Intensive tillage, monoculture and heavy agrochemical loading erode rhizosphere diversity (Xiang et al., 2025). If precise, drought adaptive signaling depends on a diverse resident community, then diversity erosion may progressively disable the very recruitment mechanism that microbiome-based agriculture hopes to exploit. An important caveat should temper this interpretation. Dilution-to-extinction alters richness but does not hold composition constant, because rare taxa and their functional genes are lost together. \"Diversity\" is therefore an operational rather than a clean variable here, and the design cannot separate the effect of species richness itself from the loss of specific keystone lineages. Resolving this will require synthetic communities of matched composition but varied richness, assembled across contrasting soils. In this study, author elegantly used effective dilutions (10 -1 , 10 -4, 10 -7 ), which allow the quantitative separation of diversity function correlation without confusing community composition effects (CCE)Figure 1) (Chen et al. 2026). In response to drought stress, high-density rhizosphere community (D1), triggers the accumulation of 2-naphtholic acid (2-NA) at 16.54 μg•mL⁻¹, while moderate diversity (D2)and low diversity (D3) soils yielded significantly reduced (0.27 g.mL⁻¹) and undetectable concentration, respectively. However, the 2-NA was totally absent in all well water saturated condition regardless the diversity level, indicating that drought is the triggering signal and indicator of microbial diversity as it confirmed by quantitative amplifier of the specific chemical response (Chen et al. 2026).This overall scenario represents a \"cry-for-help\" model, refers to an adaptive defense mechanism where drought stressed-soybean plant induces root exudates to recruit beneficial microbes (Tharp et al.2026).Li et al. ( 2025) have revealed that drought induces microbiome and metabolic enrichment that help to enhance drought resistance in soybean (Li et al. 2025). In this current study, the microbial variations play crucial role in regulation of root exudates.However, the mechanistic insights into diversity dependence misinterprets in phenylpropanoid biosynthesis. Combined analysis of transcriptome and metabolomic revealed that the pathways related to phenylpropanoid metabolism were particularly high-diversity of microbes, drought-stressed rhizosphere, connecting 2-NA accumulation to this recognized secondary metabolite production route (Chen et al. 2026). This study outputs connect the broader evidence that microbiome variation reshapes secondary metabolism in response to abiotic stress, supporting the production of benzenoids and several lipid-derivative compounds that facilitate to recruit beneficial microbes (Li et al. 2025;Yang et al.2025;Kazarina et al.2025).A conceptual opinion is that microbial diversity acts as an upstream ecological fitter that restricts the breadth of host drought-response rewiring. Low density of rhizosphere showed wider range of transcriptional reprogramming where 3530 genes expressed differentially in D7, while 550 genes expressed in D1. These findings suggest that high diversity communities (HDCs) regulate plant stress responses by providing functional support to plants at molecular level known as molecular self-help (Chen et al. 2026). This connects with the insurance strategy of biodiversity; wherein diverse communities provide redundant functional power that alleviates ecosystem processes in unrest condition (Yang et al.2021;Domeignoz-Horta et al.2024). However, in case of holobiont wherein the microbial diversity modulates the plants stress investment strategy that exchange metabolic breadth for chemical care. These findings explore a cautionary aspect of agricultural intensification. Moreover, Lack of proper strategies on tillage, monoculture and uncontrolled use of agrochemicals significantly damage rhizosphere microbial diversity (Xiang et al. 2025). If microbial diversity (MD) is a requirement for precision chemical signaling that facilitates effective drought-adaptive microbiome recruitment. In contrast, diversity erosion (DE) may steadily impair the plants' ability to organized rhizosphere assembly (RA) under environmental stress, indicating vulnerability that warrants prompt attention for designing climate-smart future crops.Exudate-mediated recruitment is not itself novel: malic acid attacts Bacillus subtilis, strigolactones recruit arbuscular mycorrhizal fungi, flavonoids initiate rhizobial nodulation through NodD (Ruan et al. 2026;Qiao et al. 2024). What distinguishes 2-NA is that a single benzoid appears to three roles at a once (Chen et al. 2026;Niu et al., 2025). It acts as chemoattractant sensed by three methyl-accepting chemotaxis protein (ΔmcpU, ΔmcpY, ΔmcpZ), with a deletion mutant showing substantially reduced chemotaxis and root colonization. It serves as a nutritional reward taken up through an ATP-binding cassette (ABC) transporter system encoded upgBAEI, it functions as a regulatory ligand that binds Ncycling protein NirK, NapA, and FixI, confirmed by molecular docking and microscale thermophoresis, with napA expression strongly induced in co-culture. Comparable metabolite-driven shaping of rhizosphere bacteria has been reported during drought and rehydration in other systems (Lei et al., 2025;Zhao et al.,2025).2-NA identified as diversity-induced root exudate that accumulates in response to drought stress and help to microbiome assembly (Chen et al. 2026). Root exudate-mediated Ku recruitment has previously emphasized on how malic acid attracts Bacillus subtilis, strigolactons recruit arbuscular mycorrizal fungi, and flavonoids initiate rhizobial nodulation (Ruan et al. 2026;Qiao et al. 2024). The emerging role of a specific benzenoid acts as drought-responsive chemoattractant exhibits this functional level that reveals that metabolite variability in root exudates drought-specific information (Niu et al. 2025).Chen et al. ( 2026) explore three different functions of 2-NA that combinedly generate a cascading plant-microbe interaction. First, 2-NA acts as a chemoattractant. Chen et al. (2026) found that Sinorhizobium CS204 induces 87% higher chemotaxis regarding 2-NA compared to control, where the colonization efficiency increased by 361.86% after 2-NA application (Chen et al. 2026). The deletion mutants (ΔmcpU, ΔmcpY, ΔmcpZ) produced three MCPs are the primary sensors mediating this chemotactic response (Figure 1), with binding free energies of -5.9 to -7.0 kcal.mol -1 (Chen et al.). However, loss of function mutants exhibited 54-61% decline in chemotaxis and 17-69% reduction in root colonization, ensuring the genetic proof of the MCP-2-NA sensory axis (Chen et al. strains, so the specificity of 2-NA for beneficial taxa as opposed to the many soil bacteria that metabolize aromatic compound remains open. Until these gaps are closed, 2-Na is a compelling mechanistic exemplar rather than an established lever.The functional payoff reported by Chen et al. ( 2026) is nutritional. Under drought, restricted mass flow limits N delivery, impairing protein synthesis, photosynthesis and reactive-oxygen scavengers (de Vries et al., 2020). Co-application of 2-NA with Sinorhizobium CS204, increased plant biomass roughly 38%, improved photosynthesis and stomatal performance, altered expression of antioxidant and drought-responsive genes and raised tissue concentration of several mineral nutrients (Figure 1). This is consistent with growing evidence that rhizobia influence soil N cycling well beyond classical nodule symbiosis, and with field demonstration that improved rhizobial inoculants can raise nodulation, N-fixation and legume yield (Ling et al.,2022;Shah et al., 2024).One consequence deserves more scrutiny than it has received. The treatment reportedly upregulates denitrification (NirK, NapA, NorB, NosZ) alongside N-fixation. Denitrification is not a uniformly benign process: incomplete denitrification is a major source of nitrous-oxide, a greenhouse gas with high radiative forcing, and drying-rewetting cycles are known hotspots for such emissions. A drought mitigation strategy stimulates denitrification could therefore trade water-stress resilience against climate burden. No N2O flax data accompany the current work, and in our view no scald application should be contemplated until the NosZ-to-NirK balance and the resulting N2O:N2 product ratio are measured directly in soil.The gap between these results and agricultural practice is substantial, and we think it should be started plainly rather than bridged rhetorically. Persistence is the first obstacle: naphthalene-derived acids are readily biodegraded from common soil bacteria and sorb strongly to organic matter and clays, so the effective rhizosphere concentration of an applied dose is unlikely to resemble that achieved in controlled systems. Soil type, pH, temperature and moisture regime will all modulate this, and more has been varied systematically.Second, ecological selectivity is unproven at community scale. Applying an aromatic acid to soil may preferentially favor aromatic-degrading taxa, some of which are opportunists, and could shift community structure in ways that are unhelpful or difficult to reverse. Third, the biosafety and regulatory position of applying a naphthalene derivative to agricultural soil is not trivial and has not been addressed. Fourth, the economics of synthesizing and delivering a defined metabolite at field scale, alongside a live inoculant with its own formulation and shelf-life constrains, remain unexplored.These considerations argue for two parallel and non-exclusive strategies. The more immediately actionable is restoration of soil microbial diversity through reduced tillages, cover cropping, diversified rotation and organic amendment, supporting the endogenous capacity for 2-NA-mediated recruitment.The more speculative is targeted co-application of a metabolite with a compatible keystone strain as a biostimulant, which should be treated as research program rather than a near-term product. Progress of both will depend on standardized multi-omics frameworks capable of linking microbial community composition to function across sites and seasons, an area where methodological harmonization remains a recognized bottleneck (Kumar et al., 2023).Chen et al. ( 2026) provide the latest mechanistic framework to date of how resident microbial diversity conditions a plant's chemical recruitments of beneficial partners under drought. We found it as evidence that diversity is a functional prerequisite for practice host signaling, and that individual exudates can be multifunctional in ways that classical signal-versus-substrate distinctions do not capture.. The priorities we would set are correspondingly modest and testable, identification and genetic validation of the 2-NA biosynthesis pathway; measurement of exudation kinetics under realistic, fluctuating drought rather than imposed step changes; determination of the fate, half-life and sorption behavior of 2-NA across contrasting soils; assessment of community-level and N2O consequences; and examination of whether diversity-conditioned signaling operates in cereals and other legumes (Gahlot, 2026). Multi-side field evaluation should follow, not precede, these steps. Framed this way, the contribution of this work is conceptual rather than immediately applied. It does not yet deliver droughtsmart agriculture but clarifies what such a strategy would need to be built upon and it suggest that protecting the diversity already present in agricultural soils may be a more reliable investment than engineering it. However, this study further opens new dimension of research on diversity-dependent chemical ecology of drought adaptation in soybean that incorporated plant metabolomics, bacterial sensor biology and N biogeochemistry, which merely resolves a long-standing gap in our understanding of diversity function relationship in the rhizosphere but also microbiome-assisted climate-smart crop improvement.","根际生态学、化学信号传导以及胁迫适应性可持续农业解决方案的更广阔图景。本文就相关主题和研究的新维度提出观点。第一，微生物多样性应被视为宿主化学信号传导的上游约束条件，而非植物表现的相关变量。第二，2-NA最好被理解为多功能根系分泌物的原理验证，而非候选农业投入品。第三，机制与田间部署之间的距离远大于当前对微生物组工程的热情所暗示的程度。Chen等（2026）的新颖见解表明，在干旱胁迫下与最高多样性群落（D1）共生的植物积累了约16.5 μg•mL⁻¹的2-NA，而中等多样性（D2）约为0.27 μg•mL⁻¹，最低多样性土壤（D3）则未检出。由于在充分浇水处理中2-NA不可检测，干旱似乎是触发因素，而多样性则充当增益控制。整合转录组学和代谢组学分析将2-NA积累与苯丙烷类相关代谢联系起来，这与更广泛的证据一致，即群落背景在非生物胁迫下重塑植物次生代谢（Li et al., 2025; Kazarina et al., 2025; Yang et al., 2025）。我们的解读颠覆了传统框架。“求救”叙事将植物视为施动者、微生物组视为响应者，而我们则认为 resident community（驻留群落）设定了植物所能做出反应的范围。特别是，低多样性根际表现出远比高多样性根际更广泛的转录重编程。我们将其解释为一种代谢经济：当多样性群落提供功能保险时，宿主可以进行狭窄而精准的投入；当缺乏这种保险时，植物则被迫采取昂贵、弥散且靶向性较弱的响应（Yang et al., 2021; Domeignoz-Horta et al., 2024）。据此观点，多样性是化学信号资本。这带来了一个令人不安的农艺学含义。集约耕作、单作和大量农用化学品投入侵蚀根际多样性（Xiang et al., 2025）。如果精准的干旱适应性信号传导依赖于多样化的驻留群落，那么多样性侵蚀可能逐步削弱基于微生物组的农业所希望利用的正是这一招募机制。一个重要警告应缓和这一解读。稀释至灭绝改变了丰富度，但并未保持组成恒定，","Frontiers in Plant Science","论文",{"impact":81,"substance":17,"depth":19,"authority":82,"freshness":46,"relevant":22,"comment":187},"该文以观点文章形式系统梳理了根际微生物多样性调控大豆干旱信号2-NA的机制与田间应用差距，学术增量明确，但属机理性讨论而非产业级突破。",[189],{"name":184,"url":181},[191,27,192,193,194],"大豆","干旱适应","根系分泌物","微生物组工程",{"code":196,"slug":197,"name":198,"path":199,"parent_code":37},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate",[201],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":203},{"candidates":204,"agricultural_evidence":47},[205,211,216,223,230,237],{"code":196,"score":82,"supported":47,"title":206,"abstract":208,"tags":210},[207],"drought",[209,207],"干旱",[],{"code":33,"score":13,"supported":47,"title":212,"abstract":213,"tags":215},[],[97,49,34,214],"rhizosphere",[27],{"code":217,"score":69,"supported":47,"title":218,"abstract":219,"tags":222},"H6",[],[220,221],"生物多样性","biodiversity",[],{"code":224,"score":225,"supported":47,"title":226,"abstract":227,"tags":229},"A4",4,[],[228],"soybean",[191],{"code":231,"score":232,"supported":47,"title":233,"abstract":234,"tags":236},"B7",3,[],[235],"greenhouse",[],{"code":238,"score":232,"supported":47,"title":239,"abstract":240,"tags":242},"H8",[],[241],"可持续农业",[],[244,245],"2-萘甲酸 根际微生物","Sinorhizobium CS204 大豆","2-萘甲酸根际微生物-5149","10.3389\u002Ffpls.2026.1938013",{"doi":247,"openalex_id":249,"authors":250,"venue":184,"cited_by_count":66,"oa_url":268,"card":269,"direction":275,"ingested_from":276},"W7222595413",[251,254,257,260,263,265],{"name":252,"orcid":253},"Md Atikur Rahman","https:\u002F\u002Forcid.org\u002F0000-0001-6779-9599",{"name":255,"orcid":256},"S.

However, comparative studies of rhizosphere bacterial communities associated with male and female date palm ( Phoenix dactylifera L.) plants remain relatively limited. Therefore, this study aimed to compare the rhizosphere bacterial communities associated with male and female date palm plants. Methods Rhizosphere bacterial communities associated with male and female date palm plants were investigated using 16S rRNA gene amplicon sequencing to evaluate differences in bacterial community composition and diversity associated with plant sex. Results Across both sexes, the rhizosphere microbiome was dominated by Firmicutes, Proteobacteria, Actinobacteriota, Acidobacteriota, and Chloroflexi, with Bacillus -related taxa prominent at lower taxonomic levels. Shannon diversity and observed features did not differ significantly between female and male samples ( p = 0.1266 and p = 0.13, respectively). In contrast, beta diversity analysis revealed no significant separation between male and female communities, indicating similar overall community structure. Although exploratory differences in relative abundance were observed for certain taxa (Bdellovibrionota, Entotheonellaeota, Planctomycetota, Micromonosporales, Thermomicrobiales, Pedosphaerales, and Chitinophagales). Conclusion Male and female date palm plants harbor broadly similar rhizosphere bacterial communities with analyzing differences in selected taxa. These preliminary observations warrant further investigation with larger sample sizes, functional approaches, and explicit consideration of reproductive stage effects, with potential implications for developing microbiome-informed strategies to enhance soil health and sustainable date palm productivity.","背景与目标 根际微生物组在植物营养、健康和抗逆性中发挥着至关重要的作用，有助于支撑可持续农业，并促进实现可持续发展目标2（零饥饿）和可持续发展目标12（负责任消费和生产）。然而，针对雄性和雌性枣椰树（Phoenix dactylifera L.）植株根际细菌群落的比较研究仍相对有限。因此，本研究旨在比较雄性和雌性枣椰树植株相关的根际细菌群落。方法 采用16S rRNA基因扩增子测序技术研究雄性和雌性枣椰树植株相关的根际细菌群落，以评估植物性别相关的细菌群落组成和多样性差异。结果 在两种性别中，根际微生物组均以厚壁菌门（Firmicutes）、变形菌门（Proteobacteria）、放线菌门（Actinobacteriota）、酸杆菌门（Acidobacteriota）和绿弯菌门（Chloroflexi）为主，在较低分类水平上以芽孢杆菌（Bacillus）相关类群最为突出。雌性和雄性样本之间的Shannon多样性和观测特征数无显著差异（分别为p = 0.1266和p = 0.13）。相比之下，β多样性分析未显示雄性和雌性群落之间存在显著分离，表明整体群落结构相似。尽管在某些类群中观察到了相对丰度的探索性差异（蛭弧菌门Bdellovibrionota、Entotheonellaeota、浮霉菌门Planctomycetota、小单孢菌目Micromonosporales、热微菌目Thermomicrobiales、Pedosphaerales和噬几丁质菌目Chitinophagales）。结论 雄性和雌性枣椰树植株拥有大体相似的根际细菌群落，但在部分选定类群上存在分析差异。这些初步观察结果值得通过更大的样本量、功能研究方法以及明确考虑生殖阶段效应来进一步研究，这对于制定基于微生物组的策略以增强土壤健康和可持续枣椰树生产力具有潜在意义。","Frontiers in Sustainable Food Systems","2026-10-09T00:00:00Z",63,{"impact":21,"substance":81,"depth":20,"authority":288,"freshness":46,"relevant":22,"comment":289},13,"基于16S rRNA测序比较雌雄枣椰树根际细菌群落，结论为性别间群落结构总体相似，属探索性研究，对农业信息化与智慧农业的直接价值有限。",[291],{"name":284,"url":281},[241,293,28,294,295],"土壤健康","枣椰树","根系微生物组",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":299},{"candidates":300,"agricultural_evidence":47},[301,305,310,316],{"code":33,"score":81,"supported":47,"title":302,"abstract":303,"tags":304},[214],[97,49,34,214],[293],{"code":238,"score":131,"supported":47,"title":306,"abstract":307,"tags":309},[],[241,308],"sustainable agriculture",[241],{"code":311,"score":232,"supported":47,"title":312,"abstract":313,"tags":315},"I7",[],[314],"研究方法",[],{"code":58,"score":22,"supported":14,"title":317,"abstract":318,"tags":319},[],[],[28],[321,322],"枣椰树 根系细菌 性别差异","根系微生物组 农业微生物 可持续农业 土壤健康","枣椰树根系细菌性别差异-4553","10.3389\u002Ffsufs.2026.1962182",{"doi":324,"openalex_id":326,"authors":327,"venue":284,"cited_by_count":66,"oa_url":334,"card":335,"direction":339,"ingested_from":276},"W7221094157",[328,331],{"name":329,"orcid":330},"Asmita Detroja","https:\u002F\u002Forcid.org\u002F0009-0004-8458-5858",{"name":332,"orcid":333},"Ashok Kumar Bishoyi","https:\u002F\u002Forcid.org\u002F0000-0001-6810-2511","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1962182\u002Fpdf",{"tldr":336,"method":337,"finding":338,"direction":339,"opportunity":340},"比较雌雄枣椰树根际细菌群落，发现整体结构相似但个别类群有差异。","16S rRNA扩增子测序分析雌雄枣椰树根际细菌组成与多样性。","雌雄根际细菌多样性和群落结构无显著差异，仅少数类群相对丰度存在探索性差异。","农业遥感与作物表型","可扩大样本并结合功能宏基因组与生殖阶段，验证性别相关根际微生物差异及其对土壤健康的作用。","2026-10-10T23:30:05.976947Z",{"id":343,"title":344,"url":345,"summary":346,"summary_zh":347,"content":8,"source_name":348,"source_url":345,"published_at":349,"category":185,"cover_url":8,"hotness":350,"is_selected":14,"score":351,"score_detail":352,"sources":354,"tags":358,"primary_topic":363,"secondary_topics":364,"classification":371,"search_phrases":408,"slug":411,"view_count":225,"doi":8,"paper":412,"created_at":422},4351,"Rhizosphere Microbiome Engineering for Climate-Smart Agriculture: From Synthetic Consortia to Precision Decision Support","https:\u002F\u002Fmel.cgiar.org\u002Freporting\u002Fdownloadmelspace\u002Fhash\u002F095138d10184dc7b696f79e27e716f84","Rhizosphere microbiome engineering is a promising approach that can enhance crop resilience and input use efficiency by redirecting plant–microbe–soil interactions toward predictable functions. Here, we review the mechanistic bases underlying rhizosphere assembly and stability, including root exudate-mediated selection, priority effects, keystone taxa, and metabolite-driven signaling, and connect these principles to proposed design rules for microbial inoculants. We present a generalizable Design–Build–Test–Learn (DBTL) framework for engineering synthetic microbial consortia, covering trait-to-module mapping (nutrient acquisition, phytohormone modulation, ACC deaminase activity, stress-protective metabolites, and biocontrol), compatibility screening, minimal yet robust community architectures, and iterative optimization driven by multi-omics and high-throughput phenotyping. Translation to field settings is framed as an engineering challenge defined by formulation and administration limitations, including carrier type, seed coating and encapsulation methods, shelf life, strain invasiveness, and permanence of colonization amid environmental diversity. We also summarize how integrative measurement pipelines (amplicon and shotgun sequencing, transcriptomics, metabolomics, and network or causal analyses) can advance microbiome studies from correlation to actionability. We describe how precision agriculture (sensors, remote sensing, and variable-rate inputs) and AI\u002FML (split-sample comparisons, transfer learning, and active learning) approaches can accelerate strain discovery, mixture optimization, and adaptive experimentation, driven by the need for stringent controls, metadata-rich reporting, and cross-site comparability. Use cases focus on stress conditions (drought, salinity, thermal extremes, and biotic stress) to demonstrate how microbial functions translate to agronomic outcomes and to highlight critical bottlenecks for reproducible, scalable microbiome products.","根际微生物组工程是一种有前景的方法，通过将植物–微生物–土壤相互作用导向可预测的功能，能够增强作物抗逆性和投入品利用效率。本文综述了根际组装与稳定性背后的机制基础，包括根系分泌物介导的选择、优先效应、关键类群和代谢物驱动的信号传导，并将这些原理与微生物接种剂拟议的设计规则相联系。我们提出了一个可推广的设计–构建–测试–学习（DBTL）框架，用于工程化合成微生物群落，涵盖性状到模块的映射（养分获取、植物激素调节、ACC脱氨酶活性、胁迫保护性代谢物和生物防治）、兼容性筛选、最小但稳健的群落架构，以及由多组学和高通量表型驱动的迭代优化。向田间环境的转化被界定为一项工程挑战，其受限于制剂和施用方面的制约，包括载体类型、种子包衣和包埋方法、货架期、菌株入侵性以及在环境多样性中定殖的持久性。我们还总结了整合性测量流程（扩增子和鸟枪法测序、转录组学、代谢组学以及网络或因果分析）如何推动微生物组研究从相关性走向可操作性。我们描述了精准农业（传感器、遥感和变量投入）以及人工智能\u002F机器学习（分样本比较、迁移学习和主动学习）方法如何加速菌株发现、混合优化和自适应实验，其驱动力在于对严格对照、富含元数据的报告和跨站点可比性的需求。应用案例聚焦于胁迫条件（干旱、盐渍、极端温度和生物胁迫），以展示微生物功能如何转化为农艺结果，并突出可重复、可规模化微生物组产品的关键瓶颈。","MELSpace (ICARDA (The International Center for Agricultural Research in Dry Areas))","2026-10-05T00:00:00Z",25,80,{"impact":81,"substance":17,"depth":81,"authority":82,"freshness":21,"relevant":22,"comment":353},"ICARDA 综述提出根际微生物组工程的 DBTL 框架并衔接精准农业与 AI，方法体系完整、结论可靠，对气候智慧型农业有参考价值，但属综述类论文、非全国性政策或重大突破。",[355,356],{"name":348,"url":345},{"name":348,"url":357},"https:\u002F\u002Fhdl.handle.net\u002F20.500.11766\u002F70900",[359,360,27,361,362],"智慧农业","农业人工智能","气候智慧型农业","合成菌群",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[365],{"code":366,"slug":367,"name":368,"path":369,"parent_code":370},"I2","agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai","I",{"status":40,"locked":14,"version":41,"method":42,"evidence":372},{"candidates":373,"agricultural_evidence":47},[374,378,386,393,397,404],{"code":33,"score":81,"supported":47,"title":375,"abstract":376,"tags":377},[214],[97,49,34,214],[27],{"code":379,"score":20,"supported":47,"title":380,"abstract":382,"tags":385},"I1",[381],"smart agriculture",[383,384],"精准农业","precision agriculture",[359],{"code":366,"score":387,"supported":47,"title":388,"abstract":390,"tags":392},12,[389],"decision support",[391],"机器学习",[360],{"code":196,"score":131,"supported":47,"title":394,"abstract":395,"tags":396},[],[209,207],[361],{"code":398,"score":69,"supported":47,"title":399,"abstract":400,"tags":403},"I3",[],[401,402],"遥感","remote sensing",[],{"code":53,"score":232,"supported":47,"title":405,"abstract":406,"tags":407},[],[29],[],[409,410],"ICARDA 根际微生物 合成菌群","根际微生物 精准农业 决策支持","ICARDA根际微生物合成菌群-4351",{"doi":8,"openalex_id":413,"authors":414,"venue":348,"cited_by_count":66,"oa_url":345,"card":417,"direction":275,"ingested_from":276},"W7220812607",[415],{"name":416,"orcid":8},"Nourhan Fouad Mahmoud",{"tldr":418,"method":419,"finding":420,"direction":273,"opportunity":421},"综述根际微生物组工程，提出DBTL框架设计合成菌群，并融合精准农业与AI实现气候智慧型农业。","综述根际组装机制，提出DBTL框架，整合多组学、高通量表型、传感器与AI\u002FML方","微生物组工程需从相关走向可操作，精准农业与AI可加速菌株发现和菌群优化，但田间可重复性仍是瓶颈。","可研究AI驱动的根际微生物组设计-田间验证闭环，重点解决菌群定殖持久性与跨站点可迁移性。","2026-10-07T23:30:12.909703Z"]
