This study examined anatomical and physiological aspects related to the effects of the cultivation environment of the stock plants and the timing of wounding at the base of cuttings on the success of propagation. Stock plants were cultivated under full sunlight, shade netting, and greenhouse conditions, while cuttings were wounded at their bases at 0, 7, and 14 days after cutting. Rooting, morphoanatomy, and physiology of both stock plants and cuttings were evaluated, together with the ontogeny of adventitious roots. Greenhouse cultivation promoted greater growth, higher photosynthetic efficiency, and increased carbohydrate concentrations, as well as reduced lignification and phenolic compound accumulation in the cortical region. The phytohormones indole-3-acetic acid and jasmonic acid, together with peroxidase enzyme activity and the ratios of indole-3-acetic acid to 1-aminocyclopropane-1-carboxylic acid, peroxidase, and abscisic acid, showed strong positive correlations with rooting, whereas abscisic acid and zeatin showed negative correlations. Cultivation under 70 % shading and wounding applied seven days after cutting favored adventitious root formation. Adventitious root ontogeny in <em>C. brasiliense</em> is multisite, originating from the vascular cambium, phloem, cortex, and callus, depending on the cutting's origin in relation to the stock plant's cultivation environment.

Industrial emissions, agrochemical misuse, and wastewater irrigation contribute to the accumulation of toxic metals such as cadmium, lead, arsenic, and mercury in soils, where they disrupt nutrient cycling and impair plant metabolism. Simultaneously, drought and salinity, exacerbated by climate change, alter soil moisture and ion balance, enhancing metal bioavailability and toxicity. The combined effects of these stresses intensify oxidative damage, inhibit photosynthesis, and reduce crop yield. Plants employ multifaceted defense mechanisms, including activation of antioxidant enzymes, osmolyte accumulation, and regulation of metal transporters, supported by hormonal and transcriptional networks.

In this study, the growth quality and rhizosphere microbial diversity of wild and cultivated <em>Paeonia lactiflora</em> Pall. collected from various producing areas in North China were analyzed in relation to soil chemical properties and climatic conditions. Methods such as high-performance liquid chromatography, Mantel tests, and microbial-quality correlation analysis were employed to investigate the effects of cultivation practices on medicinal quality and to identify key environmental factors driving rhizosphere microbial communities. The results demonstrated that growth parameters (e.g., root length and diameter) and bioactive compound contents (e.g., paeoniflorin, oxypaeoniflorin) were significantly higher in wild <em>Paeonia lactiflora</em> Pall. compared to cultivated plants. Production regions and cultivation practices significantly influenced rhizosphere microbial community structure. The microbial diversity in the rhizosphere of wild plants was higher, enriched with growth-promoting bacteria such as <em>Pseudomonas</em>, whereas cultivated plants favored potential pathogenic fungi like <em>Fusarium</em>. Soil chemical characteristics (pH, total nitrogen, available phosphorus), climatic variables (mean annual precipitation, sunshine duration), and producing areas were the primary environmental drivers shaping rhizosphere microbial communities. Bacterial diversity showed a significant positive correlation with root number and ash content of <em>Paeonia lactiflora</em> Pall., while fungal diversity was closely associated with the accumulation of paeoniflorin and total flavonoids. Beneficial microbes, including <em>Reyranella</em>, <em>Xanthobacteraceae</em>, and <em>Streptomyces</em>, exhibited significantly positive correlations with medicinal growth and secondary metabolite accumulation. In conclusion, this study elucidates the “microbe–environment–medicinal quality” interaction mechanism and highlights multi-factorial synergy in determining the medicinal quality of <em>Paeonia lactiflora</em> Pall. These findings provide theoretical support and novel perspectives for the establishment of genuine production areas, sustainable utilization of medicinal plant resources, and improved cultivation management.</div></div>","PeriodicalId":48589,"journal":{"name":"Rhizosphere","volume":"37 ","pages":"Article 101252"},"PeriodicalIF":3.5,"publicationDate":"2025-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145884727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we executed a two-year study to examine the effects of root colonization by two AMF species (<em>Diversispora epigaea</em> and <em>Diversispora versiformis</em>) under different drought stress conditions, assessing maize morpho-physiological and biochemical characteristics, nutrient absorption, yield components, oil percentage, and irrigation water efficiency. The research was conducted in a desolate region of Pakistan during the 2023 and 2024 growing seasons. Drought-induced stress was generated at two levels by irrigating after 80 % and 60 % water loss, categorized as severe and mild drought stress. Irrigation after a 40 % reduction in water was considered normal (without stress). The findings demonstrated that regardless of AMF species and level of drought stress, inoculated plants yielded heavier seeds, higher dry matter, chlorophyll (37 %) and carotenoids (41 %), phytohormone (27 %), enhanced oil yields (32 %) and seeds (24.2 %) compared to uninoculated plants. Notably, the maize seed yields of <em>Diversispora epigaea</em>-treated plants under every irrigation treatment surpassed those of <em>Diversispora versiformis</em> inoculated plants and uninoculated plants. Drought stress reduced nitrogen levels in seeds and leaves, whereas AMF enhanced nitrogen levels, particularly when crops were treated with <em>Diversispora epigaea</em>. Moreover, seed phosphorus percentages were not influenced by AMF in 2023. Conversely, the highest phosphorus percentages in seeds and leaves were recorded in crops inoculated with <em>Diversispora epigaea</em> in 2023. Our findings indicate that <em>Diversispora epigaea</em> exhibits greater efficiency under water stress and provides superior support to maize plants.</div></div>","PeriodicalId":48589,"journal":{"name":"Rhizosphere","volume":"37 ","pages":"Article 101250"},"PeriodicalIF":3.5,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of Cd-immobilizing bacteria combined with biochar on Cd speciation in wheat fields and subsequent Cd accumulation in wheat remain unclear. This study investigated the impacts and underlying soil mechanisms of applying the urease-producing bacterium <em>Enterobacter</em> sp. TJ6 and pig manure biochar (PMB) on wheat growth and Cd uptake using pot experiments. Results demonstrated that the combined application of TJ6 and PMB increased (10.8 %) wheat grain dry weight and reduced (72.1 %) grain Cd concentration compared to the control. This reduction was primarily attributed to the conversion of bioavailable Cd in the rhizosphere soil into organically-bound and residual Cd fractions. Increaseing soil pH, electrical conductivity, NH₄⁺ content, NH₄⁺/NO₃⁻ ratio, and urease activity promoted the immobilization of Cd onto soil particles, consequently decreasing the concentration of bioavailable Cd. Furthermore, the TJ6+PMB amendment facilitated the formation of insoluble Cd precipitates, such as Cd₃(PO₄)₂, CdCO₃, and (Cd,Ca)₅(PO₄)₃OH, within the rhizosphere soil. Compared to the fungal community, the bacterial community in the rhizosphere exhibited greater sensitivity to TJ6+PMB application. The relative abundances of key bacterial genera, including <em>Sphingomonas, Bacillus, Gemmatimonas,</em> and <em>Nocardioides,</em> were significantly enhanced. These genera play crucial roles in heavy metal immobilization, plant growth promotion, and nitrogen cycling. In conclusion, the application of strain TJ6 and PMB effectively reduced Cd bioavailability and uptake by wheat through the regulation of rhizosphere soil physicochemical properties and microbial community structure. These findings provide a practical approach for the remediation and safe production of wheat in Cd-contaminated fields.</div></div>","PeriodicalId":48589,"journal":{"name":"Rhizosphere","volume":"37 ","pages":"Article 101249"},"PeriodicalIF":3.5,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145939436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review synthesizes current advances in understanding the molecular and physiological factors governing AM symbiosis, with emphasis on transcriptional, hormonal, and nutrient-mediated regulation. From pre-symbiotic signaling to root colonization and arbuscule development, AM formation is orchestrated by a complex network of molecular interactions. Transcription factors, including those with GRAS domains (e.g., NSP1, NSP2, RAM1, and DELLA), and other regulators such as MYB, SPX, WRKY, and CYCLOPS/IPD3, serve as central modulators of symbiosis-related gene expression. Phytohormones, including strigolactones, salicylic acid, and abscisic acid, generally promote symbiosis, whereas gibberellins and ethylene act as inhibitors; cytokinin exerts context-dependent effects. Nutrient status also modulates AM formation—low phosphorus and nitrogen promote, while high nutrient availability suppresses colonization. Collectively, these insights reveal the integrative regulatory networks driving AM symbiosis and offer new avenues to optimize symbiotic efficiency for enhanced plant growth and agricultural sustainability.</div></div>","PeriodicalId":48589,"journal":{"name":"Rhizosphere","volume":"37 ","pages":"Article 101248"},"PeriodicalIF":3.5,"publicationDate":"2025-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145798607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electromagnetic induction and electrical resistivity tomography were used to map soil spatial heterogeneity, revealing distinct soil units (Yolo silt loam and Reiff very fine sandy loam) with varying physical and hydraulic properties. Electrical capacitance measurement successfully evaluated root system size as we found a positive correlation between root electrical capacitance and root dry mass in both rootstocks. Our results also show that root capacitance was consistently higher in the high vigor and drought resistant 110R than in the moderate vigor and drought sensitive 101-14, highlighting root system differences between the rootstocks. Furthermore, we found that vine water status, indicated by stem water potential and stomatal conductance, varied significantly between rootstocks and locations, and are driven by the underlying soil properties. This research demonstrates the utility of integrating geophysical and electrical methods for field-based phenotyping, providing novel insights into the soil-plant continuum.
