Here, we characterize IRAMC:0087, a rhizobial strain isolated from root nodules of the Saharan shrub Calobota saharae in southern Tunisia. Phenotypic assays showed high tolerance to heat, salinity, and osmotic stress, together with plant growth-promoting traits including indole-3-acetic acid production, phosphate solubilization, and siderophore secretion. In vivo assays demonstrated effective nitrogen-fixing nodulation of Vachellia tortilis , whereas Medicago and Trifolium species were not nodulated despite growth promotion through non-symbiotic mechanisms. Confocal microscopy confirmed root colonization and nodule occupancy, indicating host-dependent infection behavior. To better understand the physiological behavior of this strain, its complete genome sequence was generated, revealing a 7.37 Mb circularized genome comprising five replicons: a 3.65 Mb chromosome, two megaplasmids corresponding to pSymA (0.59 Mb) and pSymB (1.67 Mb), and two accessory plasmids, with an overall GC content of 62%. Phylogenomic, Average Nucleotide Identity (ANI), and digital DNA–DNA hybridization (dDDH) analyses assigned IRAMC:0087 to Sinorhizobium meliloti . However, comparative genomics revealed marked structural and functional divergence of pSymA_IRAMC:0087 from S. meliloti 1,021, with greater similarity to S. garamanticum and S. numidicum . NodC phylogeny placed the strain within symbiovar tunisiaense , consistent with its distinct host range. Genome annotation further identified determinants linked to stress tolerance, rhizosphere competitiveness, bioactive metabolite production, signaling, and symbiosis, including genes located on accessory plasmids. These findings highlight IRAMC:0087 as a desert-adapted rhizobium with distinctive symbiotic properties and strong ecological fitness, providing insights into rhizobial evolution in arid environments.","干旱生态系统促进了适应严重非生物胁迫且保留共生能力的根瘤菌菌株的产生。在此，我们对IRAMC:0087进行了表征，该菌株是从突尼斯南部撒哈拉灌木Calobota saharae的根瘤中分离得到的根瘤菌菌株。表型分析显示，该菌株对高温、盐度和渗透胁迫具有高度耐受性，并具有促进植物生长的特性，包括产生吲哚-3-乙酸、溶解磷酸盐和分泌铁载体。体内试验表明，该菌株能有效结瘤固氮于Vachellia tortilis，而Medicago和Trifolium物种虽通过非共生机制获得生长促进，却未被结瘤。共聚焦显微镜证实了根系定殖和根瘤占据，表明其感染行为具有宿主依赖性。为更好地理解该菌株的生理行为，我们生成了其完整基因组序列，揭示出一个7.37 Mb的环化基因组，包含五个复制子：一个3.65 Mb的染色体、两个分别对应pSymA（0.59 Mb）和pSymB（1.67 Mb）的大质粒，以及两个附属质粒，总体GC含量为62%。系统发育基因组学、平均核苷酸一致性（ANI）和数字DNA–DNA杂交（dDDH）分析将IRAMC:0087归属于Sinorhizobium meliloti。然而，比较基因组学揭示，pSymA_IRAMC:0087与S. meliloti 1,021相比存在显著的结构和功能分化，而与S. garamanticum和S. numidicum更为相似。NodC系统发育将该菌株置于symbiovar tunisiaense内，与其独特的宿主范围一致。基因组注释进一步鉴定出与胁迫耐受、根际竞争力、生物活性代谢物产生、信号传导和共生相关的决定因子，包括位于附属质粒上的基因。这些发现凸显了IRAMC:0087作为一种适应沙漠的根瘤菌，具有独特的共生特性和强大的生态适应度，为理解干旱环境中根瘤菌的进化提供了见解。","Frontiers in Sustainable Food

我国首创面源污染智能监测系统，实现水体污染物动态追踪\n\n时间：2025-04-06 14:00:00 来源：科技日报 作者：马爱平\n\n记者从中国农业科学院获悉，该院农业质量标准与检测技术研究所（以下简称质标所）农业环境污染物研究室在农业面源污染监测领域取得突破。团队成功研发出全球首套面源污染智能监测系统，并制定《农业面源污染智能监测技术规范》，首次实现对流动水体中高风险抗生素、农药残留等新发污染物的实时、在线、动态监测。相关系列成果发表于《聚集体》《分析化学》《美国化学会材料快报》等国际期刊，并获2项发明专利授权。该系统已应用于海河、太湖等流域示范工程。\n\n据项目负责人、研究员程劼介绍，该项目在面源污染智能监测系统材料、技术和装备领域实现三重突破：创制多功能传感材料，开发出具有分子识别与信号增强功能的纳米复合材料，可同时捕获多类污染物，材料稳定性较传统吸附剂提升5倍以上；研发多靶标动态识别技术，结合人工智能算法，实现3类9种农药和3类10种抗生素的同步检测，检测灵敏度达ng\u002FmL级（相当于一滴水溶解十亿分之一的污染物），响应时间缩短至1分钟以内；集成全自动分析装备，采用物联网技术构建智能监测系统，集成自动采样、预处理、分析等模块，实现连续180天无人值守运行，运维成本降低70%。\n\n“新型智能监测系统针对流动水体干扰物多、对痕量污染物捕获识别难的瓶颈难题，发明了系列多功能传感材料，实现污染物高效捕获、动态富集与高灵敏识别。”程劼表示，该系统还可在河流、沟渠、养殖塘等复杂水文环境中稳定运行，耐受-20℃至50℃极端温度，防腐蚀设计使其适用于高盐度水域。通过监测数据实时上传至云端平台，结合GIS技术生成污染热力图，该系统的预警准确率达90%以上。\n\n目前，该系统已应用于太湖、海河等流域新发污染物预警监测，大幅减少了人力成本，显著提高了监测效率。程劼表示，下一步，该系统将新增全氟化合物、内分泌干扰物、微塑料等新污染物检测功能，未来有望应用在日常水质监测、水产养殖等更多领域。\n\n编辑：韦璐\n\n本作品如有侵权，请联系我们及时删除。联系电话：010-67175015\n\n*

low supply of nitrogen from the organic reserves and the losses of the inorganic fertilizers in irrigated fruit crops. Methods We tested two cover crop mixtures, one with more and the other with less legume proportions, and one treatment where the spontaneous weeds were left to grow, before planting melon or intercropping in a mango orchard. Biomass of the cover crops and the weeds were cut and incorporated or left on the soil surface. Results In general, incorporation or surface placement did not significantly differ. The cover crop aboveground biomass production in the mixtures varied from 5.82 to 11.95 Mg ha −1 y −1 while the spontaneous weeds biomass varied from 2.18 to 6.56 Mg ha −1 y −1 . The N contents of the cover crop mixtures varied from 125 to 333 kg ha −1 y −1 , while those of the spontaneous weeds from 25 to 160 kg ha −1 y −1 . The N fixation varied from 56 to 106 kg ha −1 y −1 in the cover crop mixtures and from 17 to 102 kg ha −1 y −1 in the spontaneous weeds. Discussion These amounts are of the same order as those exported with the fruits. Thus, cover crops, especially those with high legume proportions, are promising practices in tropical irrigated fruit production system, deserving further agronomic and economic studies to validate their recommendation to producers.","引言 覆盖作物或覆盖植物，尤其是豆科植物，可以抵消灌溉果树作物中土壤有机质的耗竭、有机储备氮供应不足以及无机肥料损失的问题。方法 我们在种植甜瓜或在芒果园中间作之前，测试了两种覆盖作物混播组合，一种豆科比例较高，另一种豆科比例较低，并设置了一个让自然杂草生长的处理。覆盖作物和杂草的生物量被刈割后翻压或留在土壤表面。结果 总体而言，翻压或表面覆盖之间没有显著差异。混播组合中覆盖作物的地上部生物量产量在5.82至11.95 Mg ha⁻¹ y⁻¹之间变化，而自然杂草生物量在2.18至6.56 Mg ha⁻¹ y⁻¹之间变化。覆盖作物混播组合的氮含量在125至333 kg ha⁻¹ y⁻¹之间变化，而自然杂草的氮含量在25至160 kg ha⁻¹ y⁻¹之间变化。覆盖作物混播组合的固氮量在56至106 kg ha⁻¹ y⁻¹之间变化，自然杂草的固氮量在17至102 kg ha⁻¹ y⁻¹之间变化。讨论 这些数量与果实带走的养分量处于同一数量级。因此，覆盖作物，尤其是豆科比例较高的覆盖作物，是热带灌溉水果生产体系中具有前景的实践措施，值得进一步开展农艺学和经济学研究，以验证其向生产者推广的可行性。","2026-10-13T00:00:00Z",72,{"impact":19,"substance":287,"depth":288,"authority":106,"freshness":21,"relevant":22,"comment":289},21,17,"巴西半干旱区灌溉果园覆盖作物固氮的实测数据扎实，对绿肥与果园土壤管理有参考价值，但属区域性研究，未达每日精选门槛。",[291],{"name":100,"url":281},[29,293,294,295,296],"绿肥覆盖作物","果园生草","热带灌溉农业","土壤培肥",{"code":298,"slug":299,"name":300,"path":301,"parent_code":302},"B2","fruit","果树","\u002Ftopic\u002Fhorticulture\u002Ffruit","B",[],{"status":203,"locked":14,"version":36,"method":37,"evidence":305},{"candidates":306,"agricultural_evidence":45},[307,313,320,326,332,338],{"code":298,"score":21,"supported":45,"title":308,"abstract":309,"tags":312},[],[300,310,311],"芒果","orchard",[],{"code":314,"score":53,"supported":45,"title":315,"abstract":316,"tags":319},"A7",[],[317,318],"间作","intercropping",[],{"code":121,"score":53,"supported":45,"title":321,"abstract":322,"tags":325},[],[323,324],"土壤","soil",[],{"code":41,"score":327,"supported":45,"title":328,"abstract":329,"tags":331},4,[],[330],"肥料",[29],{"code":333,"score":130,"supported":45,"title":334,"abstract":335,"tags":337},"B1",[],[336],"甜瓜",[],{"code":339,"score":130,"supported":45,"title":340,"abstract":341,"tags":343},"H3",[],[342],"灌溉",[],[345,346],"巴西半干旱区
