Rhizosphere microorganisms,as crucial biological groups at the soil-plant interface,play a significant role in advancing sustainable agriculture.This review systematically synthesizes three decades of research to elucidate the mechanisms and applications of rhizosphere microbes—including nitrogen-fixing bacteria,phosphate-solubilizing microorganisms,and plant growth-promoting rhizobacteria(PGPR)—in enhancing soil health,improving crop stress tolerance,and optimizing ecosystem functioning.Key findings indicate that replacing 50%of synthetic nitrogen with organic fertilizer in maize-wheat rotation systems can reduce nitrous oxide emissions by up to 68%in loamy soils.Long-term no-till systems enhance carbon sequestration through microbial-driven soil organic matter accumulation.Under controlled stress conditions in greenhouse trials,microbial inoculants increase drought and salinity tolerance in tomato and rice by 50%.Modern molecular tools such as CRISPR-edited nitrogen-fixers and nano-encapsulation techniques improve microbial survival under stress by up to 68%,while tailored microbial inoculants boost crop yields by 12-40%.Case studies highlight the efficacy of synergistic microbial consortia in promoting nutrient cycling and suppressing pathogens.However,challenges remain in the field stability of microbial inoculants,low survival rates—especially below 20%in arid or acidic soils—and regulatory frameworks lag behind technological advances.Future research should prioritize developing scalable microbial technologies,fostering interdisciplinary collaboration,and refining policy frameworks to promote the widespread adoption of biofertilizers,thereby aligning with the United Nations Sustainable Development Goals(SDGs),particularly Zero Hunger and Climate Action.Effective implementation of rhizosphere engineering offers a viable pathway to translate laboratory breakthroughs into global agricultural systems,ensuring food security while mitigating environmental degradation. 展开更多

Sediment properties have a crucial effect on the growth and recovery of aquatic plants in lakes.Addition of various chemical substances has been proposed to reinforce the recovery of plants after a nutrient loading reduction.However,the effects of such sediment amendments on plant growth,especially those from rhizosphere microorganisms,is limited.We added Kaolin clay to sediments in different concentrations to explore its impact on the growth of Vallisneria natans and Ottelia acuminate and the concurrent shift in rhizosphere microorganisms using high-throughput sequencing technology.We found that the addition of low doses(10%and 20%in mass ratio)of Kaolin significantly modified sediment conditions(oxidation reduction potential and pH),with implications also for the composition,diversity,and stability of rhizosphere microorganisms.LEfSe analysis revealed that low-dose addition of Kaolin increased the abundances of functional microbial groups that benefit plant nutrient absorption and enhance plant stress resistance,such as Spirillaceae,Rhodocyclaceae,and Burkholderiales.Moreover,low doses of Kaolin significantly promoted the photosynthesis and nutrient absorption of submerged macrophytes,thereby facilitating plant growth.A structural equation model(SEM)indicated that the direct impact of Kaolin on the growth of submerged plants was relatively minor,while the indirect effect through modulation of rhizosphere microorganisms was important.Our study suggests that low doses of Kaolin may be used to promote the growth of submerged macrophytes when lakes with a high organic content in the sediment are recovering after nutrient loading reduction. 展开更多

Rhizobial inoculation in soybean is an effective strategy in sustainable agriculture to reduce chemical fertilizer application and to increase crop production.It not only provides nitrogen sources for host plants but also improves the rhizosphere soil environment.However,the inoculation efficiency of rhizobia remains to be improved.In this study,we investigated the nodulation efficiency of Bradyrhizobium and Sinorhizobium strains under different soil conditions and evaluated their impacts on the rhizocompartment bacterial community.We found that inoculation with Bradyrhizobium diazoefficiens UASD 110 increased the number of soybean nodules in acidic soil,while Sinorhizobium fredii CCBAU 45436 was more effective in alkaline soil.However,inoculation with neither strain significantly affected nodulation in neutral soil.Then,we demonstrated that UASD 110 was more competitive in nodulation than CCBAU 45436,which was related to its higher abundance in the rhizosphere.Furthermore,we showed that while single inoculation with UASD 110 or CCBAU 45436 failed to alter the bacterial diversity,these two strains differentially influenced the rhizosphere microbial composition.Finally,we identified the main rhizosphere microorganisms that were affected by these two strains.Our findings revealed that the nodulation capacity of rhizobia and their colonization of rhizosphere and nodules are soil-type dependent,yet their impact on the rhizobacterial community exhibited consistent patterns.These findings provide valuable insights into optimizing rhizobial inoculation strategies to enhance nitrogen fixation efficiency. 展开更多

Diclofop-methyl（DM）,a widely used herbicide in food crops,may partly contaminate the soil surface of natural ecosystems in agricultural area and exert toxic effects at low dose to nontarget plants.Even though rhizosphere microorganisms strongly interact with root cells,little is known regarding their potential modulating effect on herbicide toxicity in plants.Here we exposed rice seedlings（Xiushui 63） to 100 μg/L DM for 2 to 8 days and studied the effects of DM on rice rhizosphere microorganisms,rice systemic acquired resistance（SAR） and rice-microorganisms interactions.The results of metagenomic 16 S rDNA Illumina tags show that DM increases bacterial biomass and affects their community structure in the rice rhizosphere.After DM treatment,the relative abundance of the bacterium genera Massilia and Anderseniella increased the most relative to the control.In parallel,malate and oxalate exudation by rice roots increased,potentially acting as a carbon source for several rhizosphere bacteria.Transcriptomic analyses suggest that DM induced SAR in rice seedlings through the salicylic acid（but not the jasmonic acid） signal pathway.This response to DM stress conferred resistance to infection by a pathogenic bacterium,but was not influenced by the presence of bacteria in the rhizosphere since SAR transcripts did not change significantly in xenic and axenic plant roots exposed to DM.The present study provides new insights on the response of rice and its associated microorganisms to DM stress. 展开更多

To analyze the intrinsic relationship between rhizosphere microbial community structure and variety of rice, the microbial community structures in rhizosphere of different hybrid rice cultivars were determined with phospholipid fatty acids （PLFA） analysis. Three series of new-breeding hybrid rice cultivars in China were tested in the experiment, Ilyouming 86 （II-32A/Minghui 86）, Ilyouhang 1 （II-32A/Hang 1）, and Ilyouhang 2 （II-32A/Hang 2） with H-32A as female parent, XinyouHK02 （XinA/HK02） and YiyouHK02 （YXA/HK02） with HK02 as male parent, Chuanyou 167 （ChuanxiangA/MR167） and 44you167 （Hunan44A/MR167） with MR167 as male parent. The results showed that the microbial community in rhizosphere of the hybrid rice comprised bacteria, fungi, actinomycetes, and protozoa, according to the 40 PLFA biomarkers detected. Bacteria were more abundant than fungi and actinomycetes in rhizosphere of the hybrid rice tested. Both sulfate-reducing and methane-oxidizing bacteria were found to exist in the hybrid rice rhizosphere. It was also found that the characteristics of PLFA biomarkers had correlation with the biological traits of rice. The cluster analysis suggested that microbial community structure and activity in rhizosphere were associated with genetic background of the rice cultivar. 展开更多

Biological control agents and soil amendments have been applied to control tobacco bacterial wilt, but the mechanism is not well-known. In the present study, a field experiment was performed to investigate the soil physicochemical properties, disease index (DI) and disease incidence of tobacco bacterial wilt, and rhizosphere microbial community. The results show that the control efficacy of single application of antagonistic bacteria and calcium cyanamide was 46.43% and 51.92%, respectively. While the combined control efficacy of antagonistic bacteria and calcium cyanamide was 65.79%. Besides, the combined application of antagonistic bacteria and calcium cyanamide could increase soil pH, total N alkaline N, and exchangeable Ca, which were negatively associated with the microbial diversity, soil-borne pathogenic microorganisms, and incidence of tobacco bacterial wilt. Additionally, the combination of antagonistic bacteria and calcium cyanamide can improve the proportion of some antagonistic microbial species, and these antagonistic microbial species were inversely associated with the DI of tobacco bacterial wilt. In conclusion: The integrated measure may influence soil microbial communities through enhancing soil physicochemical properties and rebuild healthy soil microbial community structure to mitigate tobacco bacterial wilt. The current study presented valuable insights into the mechanisms enhancing soil health in the integrated measure. 展开更多

To have a preliminary insight into biosafety of genetically transformed hybrid triploid poplars （Populus tomentosa × P bolleana）× P. tomentosa with the cowpea trypsin inhibitor （CpTD gene, two layers of rhizospheric soil （from 0 to 20cm deep and from 20 to 40cm deep, respectively） were collected for microorganism culture, counting assay and PCR analysis to assess the potential impact of transgenic poplars on non-target microorganism population and transgene dispersal. When the same soil layer of suspension stock solution was diluted at both 1：1000 and 1：10000 rates, there were no significant differences in bacterium colony numbers between the inoculation plates of both transgenic and non-transgenic poplars. The uniform results were revealed for both soil layer suspension solutions of identical poplars at both dilution rates except for non-transgenic poplars at 1：10000 dilution rates from the same type of soil. No significant variation in morphology of both Gram-positive and Gram-negative bacteria was observed under the microscope. The potential transgene dispersal from root exudates or fallen leaves to non-target microbes was repudiated by PCR analysis, in which no CpTI gene specific DNA band was amplified for 15 sites of transgenic rhizospheric soil samples. It can be concluded that transgenic poplar with the CpTI gene has no severe impact on rhizospheric microorganisms and is tentatively safe to surrounding soil micro-ecosystem. 展开更多

Soil microbes are of vital importance in crop function and nutrient utilization.However,the core mechanisms and contributions of rhizosphere microbiota for potassium-efficient wheat varieties remain ambiguous.This article examined 24 wheat varieties,by which significant differences in rhizosphere microbial diversity and structure between potassium-efficient and-inefficient groups have been observed.It is revealed that both bacterial and fungal communities have strong correlations with wheat potassium utilization efficiency(KUE).Furthermore,this correlation is more bound up with the abundant taxa than the rare taxa.Notably,bacterial communities are demonstrated to have more substantial associations with yield and KUE compared to its counterpart,i.e.,fungal and archaeal communities.The potassium-efficient group exhibited a more complex microbial network,where bacteria occupied a more prominent ecological niche than those of fungi and archaea.Core microorganisms,primarily Bacillus and Pseudobacillus,enhance wheat KUE directly or indirectly by shaping key microbial consortium and soil microbial communities.The experiment showed that soil microorganisms make a difference in the growth and nutrient accumulation of wheat.And core microorganisms significantly facilitate wheat growth and reinforce efficient potassium nutrient absorption and utilization.This study highlighted the rhizosphere microbiome differences among wheat varieties with different potassium utilization capacities,identified and characterized the core microorganisms in the rhizosphere of potassium-efficient wheat,and revealed their potential to improve wheat potassium nutrient uptake and utilization.These findings provide valuable insights for developing wheat breeding strategies aiming at enhancing potassium utilization. 展开更多

Medicinal plants have aroused considerable interest as an alternative to chemical drugs due to the beneficial effects of their active secondary metabolites.However,the extensive use of chemical fertilizers and pesticides in pursuit of yield has caused serious pollution to the environment,which is not conducive to sustainable devel-opment in thefield of medicinal plants.Microbial fertilizers are a type of“green fertilizer”containing specific microorganisms that can improve the soil microbial structure,enhance plant resistance to biological and abiotic stresses,and increase the yield of medicinal plants.The root exudates of medicinal plants attract different micro-organisms to the rhizosphere,which then migrate further to the plant tissues.These microbes can increase the levels of soil nutrients,and improve the physical and chemical properties of soil through nitrogenfixation,and phosphorus and potassium solubilization.In addition,soil microbes can promote the synthesis of hormones that increase plant growth and the accumulation of active compounds,eventually improving the quality of med-icinal plants.In 2022,the total value of the global microbial fertilizer market was$4.6 billion and is estimated to reach$10.36 billion by 2030.In this review,we have summarized the types of microbial fertilizers,the coloniza-tion and migration of microorganisms to plant tissues,and the beneficial effects of microbial fertilizers.In addi-tion,the prospects of developing microbial fertilizers and their application for medicinal plants have also been discussed.It aims to provide a reference for the rational application of microbial fertilizers in thefield of med-icinal plants and the green and sustainable development of medicinal plant resources. 展开更多

There is a Chinese idiom called“Deep roots grow lush leaves”,which means that root health is crucial to the above-ground growth of plants.However,root health does not exist in isolation,which is largely determined by the symbiotic relationship between the root system and the rhizosphere microorganisms.The bridge that maintains this symbiotic relationship is root exudates,which not only provide a nutrient source for the rhizosphere microorganisms but also act as signaling molecules,safeguarding the health of the root system(Fan et al.,2025). 展开更多

Biosurfactants are biomolecules produced by microorganisms, low in toxicity, biodegradable, and relatively easy to synthesize using renewable waste substrates. Biosurfactants are of great importance with a wide and versatile range of applications, including the bioremediation of contaminated sites. Plants may accumulate soil potentially toxic elements(PTEs), and the accumulation efficacy may be further enhanced by the biosurfactants produced by rhizospheric microorganisms. Occasionally, the growth of bacteria slows down in adverse conditions, such as highly contaminated soils with PTEs. In this context,the plant's phytoextraction capacity could be improved by the addition of metal-tolerant bacteria that produce biosurfactants. Several sources, categories,and bioavailability of PTEs in soil are reported in this article, with the focus on the cost-effective and sustainable soil remediation technologies, where biosurfactants are used as a remediation method. How rhizobacterial biosurfactants can improve PTE recovery capabilities of plants is discussed, and the molecular mechanisms in bacterial genomes that support the production of important biosurfactants are listed. The status and cost of commercial biosurfactant production in the international market are also presented. 展开更多

Rhizosphere microorganisms,as one of the most important components of the soil microbiota and plant holobiont,play a key role in the medicinal plant-soil ecosystem,which are closely related to the growth,adaptability,nutrient absorption,stress tolerance and pathogen resistance of host plants.In recent years,with the wide application of molecular biology and omics technologies,the outcomes of rhizosphere microorganisms on the health,biomass production and secondary metabolite biosynthesis of medicinal plants have received extensive attention.However,whether or to what extent rhizosphere microorganisms can contribute to the construction of the quality evaluation system of Chinese medicinal materials is still elusive.Based on the significant role of rhizosphere microbes in the survival and quality formation of medicinal plants,this paper proposed a new concept of rhizosphere microbial markers(micro-markers),expounded the relevant research methods and ideas of applying the new concept,highlighted the importance of micro-markers in the quality evaluation and control system of traditional Chinese medicines(TCMs),and introduced the potential value in soil environmental assessment,plant pest control and quality assessment of TCMs.It provides reference for developing ecological planting of TCMs and ensuring the production of high quality TCMs by regulating rhizosphere microbial communities. 展开更多

Continuous cropping obstacles in Panax notoginseng cultivation,marked by allelochemical accumulation and soil microecological dysbiosis,were investigated through dynamic changes in soil structure,physicochemical properties,rhizosphere metabolites,and microbial communities during fallow periods.Metabolomic and metagenomic analyses of continuously cropped versus fallow soils revealed degraded soil structure with finer particles and reduced aeration post-cultivation.Severe seed germination inhibition and complete seedling mortality within months occurred in continuous cropping soil,whereas fallow practices enhanced both germination rates and seedling survival.Metabolomic profiling identified key allelochemicals enriched in continuously cropped soils,primarily terpenoids,tannins,and specific phenolic acids.These compounds correlated with enrichment of adverse genera(Pseudomonas,Sphingomonas)and suppression of beneficial taxa(Bradyrhizobium).Fallow partially restored carbohydrate and nucleotide metabolism pathways and recruited growth-promoting metabolites.Correlation analyses revealed critical metabolite-microbe crosstalk:allelochemicals promoted pathogens while suppressing symbionts essential.This integrative multi-omics approach deciphered key rhizosphere ecological interactions,demonstrating that metabolite-driven microbial shifts constitute primary drivers of continuous cropping obstacles. 展开更多

Rhizosphere microbial network in crater had higher complexity than in volcanic cone.Bacteria were more prone to enrichment than fungi in volcanic soils.The bacteria exhibited greater resistance and resilience than fungi.Volcanic eruptions are significant natural disturbances that provide valuable opportunities to study their impacts on soil microorganisms.However,no previous studies have compared the rhizosphere microbial communities of Boehmeria nivea L.in volcanic craters and cones.To address this gap,we conducted a comprehensive investigation using Illumina MiSeq high-throughput sequencing to compare the rhizosphere microbial communities in volcanic craters and cones.Principal Coordinate Analysis revealed significant differences in the rhizosphere microbial communities between the crater and cone.The bacterial communities in the rhizosphere of the crater exhibited higher diversity and evenness compared to the cones.Moreover,the cones displayed more intricate bacterial networks than the crater(nodes 556 vs.440).Conversely,fungal networks were more complex in the crater than the cone(nodes 943 vs.967).Additionally,bacterial communities demonstrated greater stability than fungal ones within these volcanic soils(avgK 241.1 vs.499.7)and(avgCC 1.047 vs.1.092).Furthermore,the Structural Equation Model demonstrated a direct positive impact of alpha diversity on soil microbial community multifunctionality in the crater(λ=0.920,P<0.001).Our findings have presented the opportunity to investigate the characteristics of the rhizosphere microbial communities of Boehmeria nivea L.in the crater and cone. 展开更多

Background:Optimizing cultivation techniques for traditional Chinese medicine has become a crucial means to improve the quality of medicinal materials.Microbial agents,as environmentally friendly and efficient plant growth promoters and soil conditioners,have increasingly attracted attention in eco-agriculture research.Objective:Our understanding remains limited regarding how the application of microbial agents,alone or in combination,affects changes in the rhizosphere microbiome and its association with the bioactive components of medicinal materials.Methods:In this study,Epimedium pubescens Maxim.was employed as a model plant to examine the effects of 2 microbial agents(Paenibacillus mucilaginosus and Bacillus subtilis)applied individually and in combination on plant growth and the accumulation of bioactive components.Additionally,this study explored the relationship between the rhizosphere microbiome and plant development.Results:The application of microbial agents increased the yield of E.pubescens leaves by 20.30%to 33.66%and enhanced the total flavonol glycosides content by 11.40%to 29.94%.Meanwhile,microbial treatments reshaped the rhizosphere microbiome,promoted the enrichment of beneficial microorganisms(e.g.,Frankia and Paenibacillus),suppressed phytopathogenic fungi such as Didymella and Scytalidium,and enhanced the stability of the soil microbial co-occurrence network.The partial least squares path model suggested that microbial agents not only directly impact the quality of medicinal herbs but also indirectly alter the accumulation of bioactive components by modulating the soil microbiome.Conclusion:These findings deepen our understanding of the relationship between medicinal plant quality and rhizosphere microbiomes as mediated by microbial agents.They also provide a basis for designing and manipulating synthetic microbial communities to promote sustainable development in eco-agriculture. 展开更多

Objective: Biofertilizers are reliable alternatives to chemical fertilizers due to various advantages. However, the effect of biofertilizers on Salvia miltiorrhiza yield and quality and the possible mechanisms remain little known. Here, an experiment was conducted in S. miltiorrhiza field treated with two kinds of biofertilizers including Bacillus and microalgae.Methods: A field experiment was conducted on S. miltiorrhiza of one year old. The biofertilizers were applied at six treatments:(i) control check, CK;(ii) microalgae, VZ;(iii) Bacillus, TTB;(iv)microalgae + Bacillus(1:1), VTA;(v) microalgae + Bacillus(0.5:1), VTB;(vi) microalgae+Bacillus(1:0.5),VTC. Here, high-throughput sequencing, ICP-MS and UPLC were employed to systematically characterize changes of microbial diversity and structure composition, heavy metals content and bioactive compounds, respectively.Results: Compared to CK, root biomass increased by 29.31%-60.39%(P < 0.001). Meanwhile, bioactive compounds were higher than CK after the application of the biofertilizers, peculiarly in TTB and VTB.However, the content of Pb contents in roots significantly reduced by 46.03% and 37.58% respectively in VTC and TTB(P<0.05). VTA application notably increased the available nitrogen content by 53.03%(P<0.05), indicating the improvement of soil fertility. Significantly, bacterial and fungal Chao I diversity indices showed an increasing trend with biofertilizer application(P < 0.05), and biofertilizer amendment enriched the rhizosphere soil with beneficial microorganisms that have abilities on promoting plant growth(Achromobacter and Penicillium), adsorbing heavy metal(Achromobacter and Beauveria), controlling plant pathogen(Plectosphaerella, Lechevalieria, Sorangium, Phlebiopsis and Beauveria) and promoting the accumulation of metabolites(Beauveria and Phoma).Conclusion: Bacillus and microalgae biofertilizers improved the quality and biomass of S. miltiorrhiza by altering microbial communities in soil. 展开更多
