Germination rates and seedling growth parameters were evaluated under Sr²⁺ concentrations of 0, 10, 100, and 1000 mM. Results revealed a significant decline in germination rates as Sr²⁺ concentrations increased, with <em>T. aestivum</em> showing higher sensitivity compared to <em>T. durum</em>. Low Sr²⁺ concentrations (10 mM) initially promoted stem growth in <em>T. aestivum</em>, but growth declined sharply at higher concentrations. Both species sustained growth at moderate Sr²⁺ concentrations (100 mM), but experienced a substantial reduction at 1000 mM, with <em>T. durum</em> demonstrating slightly better tolerance. Elevated Sr²⁺ concentrations notably affected root length and stem branching, indicating severe phytotoxic effects. Enzyme activity assays showed that at low Sr²⁺ concentration (10 mM), GST, CAT, POD, and SOD activities were similar to the control. At moderate concentrations (100 mM), GST and POD activities increased, suggesting enhanced detoxification. At high concentrations (1000 mM), all enzyme activities were significantly elevated, reflecting a robust antioxidative defense mechanism. This study provides valuable insights into the toxicological impacts and physiological responses of these wheat species to Sr²⁺ stress.</div></div>","PeriodicalId":100027,"journal":{"name":"Advanced Agrochem","volume":"4 1","pages":"Pages 49-58"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This stimulation led to a significant reduction in the total concentration of NH₄⁺‒N by more than 86％, and effective recovery of PO₄^3-‒P within three days from concentrated wastewater (WW), although the secreted EPS inhibited the conversion of MgCO₃ to specific crystal forms (MgNH₄PO₄.6H₂O or MgHPO₄.7H₂O). Moreover, with an increase in PO₄³⁻ concentration in WW, these crystals appeared, thus the removal of NH₄⁺‒N and PO₄^3-‒P nutrients can be attributed to the combined effect of <em>M. Aeruginosa</em> and MgCO₃. We used Surface-Enhanced Raman Spectroscopy (SERS) combined with X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy with Energy-Dispersive X-ray Spectroscopy (FESEM-EDS), and X-ray Photoelectron Spectroscopy (XPS) to investigate the mechanism for competitive interactions between <em>M. Aeruginosa</em> and MgCO₃ in removing NH₄⁺‒N and PO₄^3-‒P. We identified that the bound EPS accumulated amorphous Mg–P–O dense particles on <em>M. Aeruginosa</em>, while soluble EPS, containing –COOH groups of humic-like substances decreased the pH of the solution and coordinated with Mg²⁺ ions. Therefore, both secreted bound and soluble EPS play a vital role in hindering the transformation of Mg²⁺ ions or MgCO₃ to MgNH₄PO₄.6H₂O or MgHPO₄.7H₂O crystals within WW, and they enhanced <em>M. Aeruginosa</em> 's ability in absorbing nutrients of NH₄⁺‒N and PO₄^3-‒P.

The distinctive function of transamination enables the incorporation of nitrogen atoms into the backbones of steroidal specialized metabolites during the later stages of SGA biosynthesis, resulting in the production of nitrogen-containing antinutrients.

Compared to the control, the two nanoparticle treatments increased rice resistance, with VMSNs exhibiting the highest efficacy in controlling these two diseases, causing a shorter lesion length than those plants treated by MSNs. Coincidentally, the foliar application of VMSNs activates a higher expression level of several pathogenesis-related (<em>PR</em>) genes compared to those of MSNs and SiO₂ treatment. By using fluorescein isothiocyanate (FITC)-labeled VMSNs (VMSNs-FITC) to soak the top expanded leaf tips or roots, we observed that the fluorescence of the nanoparticles firstly accumulated at the local site of the top leaves or roots, rapidly migrated to the hypocotyl of rice, and then redistributed sequentially from the bottom leaves to the upper leaves. Furthermore, the foliar or root application of VMSNs-FITC could trigger the local and systemic resistance to PXO99. Notably, no significant toxicity was observed on plants and mice after excessive foliar treatment or feeding tests, respectively.
