We explored the impact of simulated erosion on major microbial groups in a pot experiment with rapeseed (<em>Brassica napus</em> L.) grown on arable soil with the potential to capture SOC. An erosion gradient was simulated by admixture (0%, 12%, 24%) of subsoil horizon (Bt) to topsoil (Ap) material. Rapeseed plants were pulse-labeled with <sup>14</sup>CO<sub>2</sub> at three growth stages and two soil compartments (bulk and rhizosphere soil) were sampled. Fungal ITS copy numbers were consistently higher in the rhizosphere and decreased with progressing plant growth stages. A significant increase of bacterial 16S rRNA gene copies in the rhizosphere only occurred at flowering. A response of fungal abundance to subsoil admixture was found detectable based on fungi:Bacteria and fungi:Archaea ratio at flowering. Archaea were neither affected by soil compartment nor subsoil admixture. <sup>14</sup>C activity of microbial biomass, an indicator for relative input of freshly assimilated C into soil microbiome, was impacted by growth stage and compartment and decreased with ongoing growth stage. During the rosette growth stage, the <sup>14</sup>C activity of the microbial biomass was elevated in the rhizosphere of the eroded soil indicating a plant response to the erosion factor.

Nitric oxide (NO) has been shown to increase plant tolerance to environmental stresses and promote the plant-fungal symbiotic relationship. However, to date, no research has been conducted to investigate the impact of utilizing living organisms with specific molecules that are effective in promoting plant growth in conjunction with the chemical alterations of HM in the rhizosphere. Therefore, this study was conducted as a completely randomized factorial design using the rhizobox technique to investigate whether the use of <em>Funneliformis mosseae</em> fungi and sodium nitroprusside (SNP, 100 mM) as a donor of NO, alone or in combination, can improve corn plant growth and affect the Cd fractions in the rhizosphere of Cd-contaminated soil. The results show that the inoculation of AMF and the application of SNP, either alone or in combination, significantly increased plant growth. This was achieved by reducing the bioavailable form of Cd in the rhizosphere, which in turn led to a decrease in the concentration of Cd in corn plant tissues. The inoculation of AMF, either alone or in combination with SNP, resulted in a decrease in the concentration of Cd in its exchangeable (EXCH), carbonate-bound (CAR), and Fe–Mn oxides-bound (MnOX and FeOX) forms, and an increase in its organic matter-bound (ORG) and residual (RES) forms in the rhizosphere. The study found that the rhizosphere had lower concentration of bioavailable form of Cd (EXCH-Cd (43%), CAR-Cd (9%), MnOX-CD (18%), FeOX-Cd (33%) and ORG-Cd (30%)) and higher concentration of low-toxic form of Cd (RES-Cd (56%)). This indicates the role of root exudates in the redistribution of Cd fractions in soil. The study also revealed that AMF colonization, in combination with SNP, affected the biogeochemical fractions of Cd and reduced Cd mobility in the rhizosphere. This improvement in Cd mobility led to reduced Cd accumulation in the plant tissues, resulting in improved corn plant growth.</p></div>","PeriodicalId":48589,"journal":{"name":"Rhizosphere","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141136760","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}

Soil plays a crucial role as a medium for plants to obtain nutrients and to exchange substances with the environment. The presence of soil microorganisms is essential for plant survival and growth. Therefore, numerous studies have been carried out to investigate the changes in soil microbial structure and soil physical and chemical properties following <em>M. micrantha</em> invasion. Here, we reviewed recent research on soil microorganisms of <em>M. micrantha</em> from three perspectives: microbial diversity, abundance, and function. We summarized that the invasion of <em>M. micrantha</em> leads to an increase in microbial diversity, which ultimately benefits the plant growth. Furthermore, the changes in soil nutrients contribute to an increase in the density and abundance of the microbial population. This leads to an enrichment of biological control bacteria, which helps to suppress pathogenic bacteria in the rhizosphere of <em>M. micrantha</em>. Additionally, the soil associated with <em>M. micrantha</em> has a higher diversity and abundance of nitrogen-fixing bacteria, ammonifiers, phosphate-solubilizing bacteria, potassium-solubilizing bacteria, and other microorganisms.

Parallelly, low molecular weight (LMW) metabolic profile of fungal filtrates was evaluated with untargeted metabolomics approach using LC-MS/TOF. The fungal isolates from kiwifruit bearing soil were much richer in LMW metabolites than those from virgin soil. Non host specific mycotoxins such as Aflaxoxin B2, Alternariol and Alterlactone were found in these isolates along with a number of metabolites most of which were characterised by antimicrobial properties. <em>D. torresensis</em> isolates were clearly discriminated from the other three species based on metabolic profile. A negative Pearson correlation between the growth index of kiwifruit vitro-plants and LMW metabolite count per isolate (richness) showed that the latter were associated with phytotoxicity, but the degree of correlation (r = −0.639) indicated that they were not the only component responsible. The results suggest that kiwifruit vines may alter the composition of the <em>Dactylonectria</em> spp. community in the root zone, which in turn may directly or indirectly contribute to kiwifruit vine decline syndrome.</p></div>","PeriodicalId":48589,"journal":{"name":"Rhizosphere","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2452219824000612/pdfft?md5=2c8a808d13e4ce50d9e51f07007320aa&pid=1-s2.0-S2452219824000612-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141164292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
