Climate warming has intensified the global hydrological cycle, amplifying the differences in precipitation and soil moisture between arid and humid areas. Such a change under regional drought may alter nitrogen (N) and phosphorus (P) releases during litter decomposition in terrestrial ecosystems, but how these biogeochemical processes respond to drought differently between arid and humid areas remains unclear. Here, we compiled 259 and 138 paired observations (with and without drought conditions) to assess the global variations in the drought effects on N and P releases during litter decomposition between arid (aridity index < 0.5) and humid (aridity index > 0.5) areas. Litter N release increased under drought in both arid (0.35%) and humid (3.62%) areas, and P release decreased by 7.32% in arid areas but increased by 2.22% in humid areas under drought. These changes in N and P releases from decomposing litter were positively correlated with drought duration in arid areas, dependent on microclimate, edaphic factors, and litter quality. Our findings highlight the contrasting effects of drought on litter N and P releases between arid and humid ecosystems, and this differential influence will greatly improve our capability to evaluate and forecast nutrient cycling during litter decomposition under different precipitation patterns.
气候变暖加剧了全球水文循环,扩大了干旱和潮湿地区之间降水和土壤湿度的差异。这种变化可能会改变陆地生态系统凋落物分解过程中氮和磷的释放,但这些生物地球化学过程如何在干旱和潮湿地区对干旱做出不同的响应尚不清楚。在此,我们收集了259和138对观测数据(有和没有干旱条件),以评估干旱对凋落物分解过程中N和P释放的全球变化。0.5)和潮湿(干燥指数>;0.5)地区。干旱条件下,干旱区和湿润区凋落物N释放量均增加(0.35%),P释放量减少(7.32%),湿润区增加(2.22%)。这些变化与干旱区干旱持续时间呈正相关,取决于小气候、土壤因子和凋落物质量。我们的研究结果强调了干旱对干旱和湿润生态系统凋落物N和P释放的差异影响,这种差异影响将极大地提高我们评估和预测不同降水模式下凋落物分解过程中养分循环的能力。

It was long accepted that the microgranular structure of many Ferralsols was mainly related to physicochemical processes and to their mineralogical composition. It now appears, however, that this microgranular structure originates from the burrowing activity of termites and ants. Given its importance for the physical properties of Ferralsols, it will be necessary to study the different termite and ant species responsible for this microgranular structure and the characteristics of the burrowing activity associated with species. This is a major point to better understand the possible long-term consequences of agriculture on Ferralsol properties because it strongly affects soil faunal biodiversity.
长期以来,人们一直认为许多费拉索尔的微颗粒结构主要与物理化学过程和矿物组成有关。然而,现在看来,这种微颗粒结构起源于白蚁和蚂蚁的挖洞活动。考虑到其对Ferralsols的物理性质的重要性,有必要研究造成这种微颗粒结构的不同白蚁和蚂蚁物种以及与物种相关的挖洞活动特征。这是更好地理解农业对Ferralsol性质可能产生的长期影响的一个要点,因为它强烈影响土壤动物的生物多样性。

The world is facing a consistent increase in human population and a noticeable decrease in cultivable lands due to soil salinization, abrupt climatic changes, and less rainfall. These problems have increased the importance of finding ecologically sustainable solutions to ensure global food security. Plant growth-promoting rhizobacteria can be advantageous to enhancing plant productivity and safeguarding against environmental stresses. They may assist plants by atmospheric nitrogen fixation, nutrient recycling, phosphate solubilization, iron sequestration via siderophore formation, and production of phytohormones like indole-3-acetic acid and 1-aminocyclopropane-1-carboxylate deaminase. They can also be used as biofertilizers and biocontrol agents as they produce antibiotics, exopolysaccharides, and hydrolytic enzymes. In this review, the connections between microbial populations, as microbial inoculants, and plant systems are highlighted, focusing on the enhancement of plant development, environmental resilience of agricultural systems, ecosystem services, and biological challenges under stressed conditions. This review also emphasizes the use of advanced molecular tools and techniques to effectively characterize potent soil microbial communities, their importance in increasing crop yield in stressed soils, and the prospects for future research.
由于土壤盐碱化、气候突变和降雨减少,世界正面临着人口持续增长和可耕地显著减少的问题。这些问题增加了寻找生态上可持续的解决办法以确保全球粮食安全的重要性。促进植物生长的根瘤菌有利于提高植物生产力和抵御环境胁迫。它们可以通过大气固氮、养分循环、磷酸盐增溶、铁载体形成的铁固存以及吲哚-3-乙酸和1-氨基环丙烷-1-羧酸脱氨酶等植物激素的产生来帮助植物。它们还可以用作生物肥料和生物防治剂,因为它们可以产生抗生素、外多糖和水解酶。在这篇综述中,强调了微生物种群(作为微生物接种剂)与植物系统之间的联系,重点是在逆境条件下增强植物发育,农业系统的环境恢复力,生态系统服务和生物挑战。本文还重点介绍了利用先进的分子工具和技术来有效表征土壤微生物群落,它们在胁迫土壤中提高作物产量的重要性,以及未来研究的前景。

Biochar application to soil is commonly recognized to improve soil fertility and consequently biomass and food production sustainably. We re-examined the robustness of the underlying data and found that, of the 12 000+ publications on “biochar and agriculture” used in meta-studies, only 109 Institute for Scientific Information (ISI) papers (or 0.9%) provide experimental data on the impacts on crop yield and/or biomass production. Our analysis revealed that none (0%) of these studies compared a biochar treatment to a treatment adding to the soil the same amounts of easily accessible nutrients as found in biochar, 0.9% evaluated the toxicity of biochar, and 5.5% considered at least two cropping cycles after a single biochar application, which in all cases are major shortcomings. Finally, when computed only for agricultural soils (n = 65), the mean biomass or grain yield gain, which was 16.1% (median at 7.1%) for all available experiments, decreased to -0.64% (median at 5.2%). Consequently, the underlying evidence base to support biochar application in agricultural soils to enhance biomass production and grain yield is so far limited.},
人们普遍认为,在土壤中施用生物炭可以提高土壤肥力,从而可持续地提高生物量和粮食生产。我们重新检查了基础数据的稳稳性,发现在元研究中使用的1.2万多篇关于“生物炭和农业”的论文中,只有109篇科学信息研究所(ISI)的论文(占0.9%)提供了对作物产量和/或生物质生产影响的实验数据。我们的分析显示,这些研究中没有(0%)将生物炭处理与向土壤中添加与生物炭中发现的相同数量的易于获取的养分的处理进行比较,0.9%评估了生物炭的毒性,5.5%考虑了一次生物炭施用后至少两个种植周期,这些都是主要缺点。最后,当仅计算农业土壤(n = 65)时,所有可用实验的平均生物量或粮食产量增益为16.1%(中位数为7.1%),降至-0.64%(中位数为5.2%)。因此,迄今为止,支持在农业土壤中应用生物炭以提高生物量生产和粮食产量的潜在证据基础有限。

New pollutants have become a significant concern in China's efforts toward ecological and environmental protection. Trichloromethane (TCM, CHCl3), one of these new pollutants, is primarily released into soil and groundwater through various industrial activities. Over the past four decades, researchers have consistently focused on the remediation of TCM-contaminated soil and groundwater using microorganisms and iron-based materials, which hold significant potential for practical application. Understanding the remediation process and the factors influencing TCM degradation through these two methods is crucial for advancing both theoretical research and practical implementation. This review focuses on the degradation mechanisms of TCM in soil and groundwater by microorganisms and iron-based materials. It summarizes the active microorganisms and modified iron-based materials with high TCM degradation capabilities, discusses enhancement measures for both methods in the remediation process, and finally, outlines the challenges faced by these methods. The goal is to provide theoretical references for efficient remediation of TCM-contaminated soil and groundwater.
新污染物已成为中国生态环境保护工作中的一个重要问题。三氯甲烷(TCM, CHCl3)是其中一种新型污染物,主要通过各种工业活动释放到土壤和地下水中。在过去的40年里,研究人员一直致力于利用微生物和铁基材料修复中药污染的土壤和地下水,这具有很大的实际应用潜力。通过这两种方法了解中药降解的修复过程和影响因素对于推进理论研究和实践实施至关重要。本文就中药在土壤和地下水中被微生物和铁基材料降解的机理进行了综述。综述了活性微生物和具有高中草药降解能力的改性铁基材料,讨论了这两种方法在修复过程中的增强措施,最后概述了这些方法面临的挑战。旨在为中药污染土壤和地下水的有效修复提供理论参考。

Salinity poses a significant challenge to global agricultural productivity, impacting plant growth, yield, soil fertility, and the composition of soil microbial communities. Moreover, salinity has a significant impact in shifting soil microbial communities and their functional profiles. Therefore, we explored and analyzed the intricate relationships among plant-associated microbes/microbiome, including plant growth-promoting bacteria, arbuscular mycorrhizal fungi (AMF), archaea, and viruses in alleviating salinity stress in plants. In this review, we have highlighted that salinity stress selectively enhances the growth of certain microbes such as Gammaproteobacteria, Bacteroidetes, Firmicutes, Acidobacteria, Euryarchaeota, Thaumarchaeota, Crenarchaeota, and lysogenic viruses, while decreasing the abundances of others (Alphaproteobacteria and Betaproteobacteria) and AMF root colonization. These microbes regulate water and nutrient uptake, decrease ionic and osmotic toxicity, enhance the syntheses of antioxidant enzymes (catalase and glutathione S-transferases) and osmolytes (erythrose and galactinol), increase phytohormone (indole-3 acetic acid) production, and activate salinity stress tolerance genes (SOD, APX, and SKOR) in plants. Furthermore, we meticulously examined the significance of soil microbiome and the need for multidisciplinary omics studies on the changes in soil microbiome composition and the relationships of synergistic holobiont in mitigating salinity stress in plants. Such studies will provide insights into the use of microbial components as a sustainable and eco-friendly approach to modulate salinity stress and enhance agricultural productivity.
盐度对全球农业生产力构成重大挑战,影响植物生长、产量、土壤肥力和土壤微生物群落组成。此外,盐度对土壤微生物群落及其功能分布有显著影响。因此,我们探索和分析了植物相关微生物/微生物组之间的复杂关系,包括植物生长促进菌、丛枝菌根真菌(AMF)、古细菌和病毒在缓解植物盐胁迫中的作用。在这篇综述中,我们强调了盐度胁迫选择性地促进了某些微生物的生长,如Gammaproteobacteria、Bacteroidetes、Firmicutes、Acidobacteria、Euryarchaeota、Thaumarchaeota、Crenarchaeota和溶原病毒,同时降低了其他微生物(Alphaproteobacteria和Betaproteobacteria)的丰度和AMF的根定殖。这些微生物调节植物对水分和养分的吸收,降低离子和渗透毒性,促进抗氧化酶(过氧化氢酶和谷胱甘肽s -转移酶)和渗透酶(红细胞和半乳糖醇)的合成,增加植物激素(吲哚-3乙酸)的产生,并激活盐胁迫耐受基因(SOD, APX和SKOR)。此外,我们还仔细研究了土壤微生物组的重要性,以及对土壤微生物组组成变化和协同全息剂在减轻植物盐胁迫中的关系进行多学科组学研究的必要性。这些研究将为利用微生物成分作为一种可持续和生态友好的方法来调节盐度胁迫和提高农业生产力提供见解。

Ceratocystis fimbriata is a hazardous fungal pathogen that causes black rot disease in sweet potato roots, leading to devastating losses during sweet potato growth and storage. All methods for managing C. fimbriata on sweet potato based on synthetic fungicides, biocontrol agents, coatings, and natural compounds are reviewed for the first time. The advantages and disadvantages of the different methods are discussed, and their efficacies are compared. Bacillus strains and the synthetic fungicides carbendazim, flutriafol, liguoling, Stadium®, thiabendazole, and thiophanate methyl show the strongest inhibitory effects. Bacillus strains possess an advantage over synthetic fungicides due to the detrimental impact of the latter on human health. The application of filamentous fungi and yeasts as biocontrol agents for C. fimbriata management has not yet been investigated. Coatings exhibit limited protection, and no attempts have been made to combine coatings with nanoparticles or essential oils. Although the natural compounds perillaldehyde and nerol are inexpensive and non-toxic, they are of low efficacy. All management strategies have been used on postharvest sweet potato roots and leaves.

丝状角鼻虫是一种危险的真菌病原体,可引起甘薯根部的黑腐病,导致甘薯生长和储存期间的毁灭性损失。本文首次综述了合成杀菌剂、生物防治剂、涂料和天然化合物等防治甘薯毛霉的方法。讨论了不同方法的优缺点,并对其效果进行了比较。芽孢杆菌菌株和合成杀菌剂多菌灵、氟triafol、立果灵、Stadium®、噻苯达唑和甲基硫代盐的抑制效果最强。由于合成杀菌剂对人体健康的有害影响,芽孢杆菌菌株比合成杀菌剂具有优势。丝状真菌和酵母作为生物防治剂在毛菌管理中的应用尚未进行研究。涂层表现出有限的保护作用,并且没有尝试将涂层与纳米颗粒或精油结合起来。虽然紫苏醛和橙花醇是廉价无毒的天然化合物,但它们的功效较低。所有的管理策略都用于采收后的甘薯根和叶。然而,在植物生长过程中,尚无有效的方法来控制植物根系中的毛霉。尽管近年来已经报道了几种控制甘薯上的红弧菌的方法,但许多知识空白阻碍了有效和安全方法的发展。

To promote growth, terrestrial plants release photosynthetic products into the rhizosphere in the form of root exudates through their root systems. Under the attraction of root exudates, plant growth-promoting rhizobacteria (PGPR) colonize the rhizosphere to stimulate plant growth and/or suppress the growth of pathogenic microorganisms. The rhizospheric recruitment of PGPR, as well as the establishment of root-microbe interactions, is initiated by chemotaxis towards root exudates. Over the past several decades, scientists have made notable strides in identifying representative chemoeffectors in root exudates, as well as the corresponding chemoreceptors. We review here the most recent developments in rhizospheric chemotaxis, particularly the chemoeffectors in root exudates, the structural and functional characterization of methyl-accepting chemotaxis proteins of PGPR, and the impacts of rhizospheric chemotaxis on root colonization, biofilm formation, and other root-microbe interactions during recruitment. Finally, we propose several perspectives that aim to fully unlock the potential of PGPR as bioinoculants in sustainable agriculture.
为了促进生长,陆生植物通过根系将光合产物以根分泌物的形式释放到根际。在根分泌物的吸引下,促进植物生长的根瘤菌(PGPR)在根际定殖,刺激植物生长和/或抑制病原微生物的生长。PGPR的根际募集,以及根与微生物相互作用的建立,是通过对根渗出物的趋化而启动的。在过去的几十年里,科学家们在确定根分泌物中具有代表性的化学效应物以及相应的化学受体方面取得了显著的进展。本文综述了根际趋化研究的最新进展,特别是根分泌物中的趋化效应物,PGPR甲基化趋化蛋白的结构和功能特征,以及根际趋化对根定植、生物膜形成和其他根-微生物在招募过程中的相互作用的影响。最后,我们提出了几个观点,旨在充分释放PGPR作为可持续农业生物接种剂的潜力。

Mechanisms of microbe-assisted metal tolerance in phytoremediators: A review 植物修复剂中微生物辅助的金属耐受机制综述

Escalating anthropogenic activities have caused heavy metal contamination in the environmental matrices. Due to their recalcitrant and toxic nature, their occurrence in high titers in the environment can threaten survival of biotic components. To take the edge off, remediation of metal-contaminated sites by phytoremediators that exhibit a potential to withstand heavy metal stress and quench harmful metals is considered an eco-sustainable approach. Despite the enormous potential, phytoremediation technique suffers a setback owing to high metal concentrations, occurrence of multiple pollutants, low plant biomass, and soil physicochemical status that affect plants at cellular and molecular levels, inducing morphological, physiological, and genetic alterations. Nevertheless, augmentation of soil with microorganisms can alleviate the challenge. A positive nexus between microbes, particularly plant growth-promoting microorganisms (PGPMs), and phytoremediators can prevent phytotoxicity and augment phytoremediation by employing strategies such as production of secondary metabolites, solubilization of phosphate, and synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase and phytohormones. Microbes can mediate tolerance in plants by fortifying their antioxidant machinery, which maintains redox homeostasis and alleviates metal-induced oxidative damage in the plants. Associated microbes can also activate stress-responsive genes in plants and abridge metal-induced toxic effects. An in-depth exploration of the mechanisms employed by plant-associated microbes to trigger tolerance in phytoremediators is crucial for improving their phytoremediation potential and real-world applications. The present article attempts to comprehensively review these mechanisms that eventually facilitate the development of improved/new technology for soil ecosystem restoration.
随着人类活动的加剧,环境基质中的重金属污染日益严重。由于它们的顽固性和毒性,它们在环境中的高滴度会威胁到生物成分的生存。为了减轻压力,植物修复剂对金属污染场地的修复被认为是一种生态可持续的方法,因为植物修复剂具有承受重金属压力和熄灭有害金属的潜力。尽管潜力巨大,但由于金属浓度高、多种污染物的发生、植物生物量低以及土壤理化状况在细胞和分子水平上影响植物,导致形态、生理和遗传改变,植物修复技术受到挫折。然而,用微生物增加土壤可以缓解这一挑战。微生物,特别是促进植物生长的微生物(PGPMs)和植物修复剂之间的积极联系可以通过产生次生代谢物、溶解磷酸盐、合成1-氨基环丙烷-1-羧酸(ACC)脱氨酶和植物激素等策略来预防植物毒性并增强植物修复。微生物可以通过强化其抗氧化机制来调节植物的耐受性,维持氧化还原稳态,减轻金属诱导的植物氧化损伤。相关的微生物也可以激活植物的应激反应基因,减轻金属诱导的毒性作用。深入探索植物相关微生物触发植物修复剂耐受性的机制对于提高植物修复潜力和实际应用至关重要。本文试图全面回顾这些机制,最终促进土壤生态系统修复改进/新技术的发展。
