NPs were characterized via UV–vis spectroscopy (peaks at 349 nm and 441 nm), FT-IR (identifying capping agents), and electron microscopy (spherical NPs, 8–56 nm). Antimicrobial assays revealed potent activity against Xoo, with Ag Nps exhibiting larger inhibition zones (31.32 mm) than ZnO NPs (19.31 mm). In vivo trials demonstrated infection reductions of 63.39% (Ag Nps) and 52.76% (Zn NPs), comparable to conventional pesticides. NPs enhanced superoxide dismutase (SOD) and peroxidase (POD) activities, thereby reducing ROS accumulation. Soil analysis indicated treatment-specific heavy metal dynamics: Zn NPs elevated Zn and Al levels. Microbial communities shifted under NP exposure; <i>Flavisolibacter, Sphingomonas,</i> and <i>Candidatus Koribacter</i> abundances varied significantly, distinguishing NP treatments from pesticides. Metabolomic profiling highlighted Ag Nps -induced upregulation of fatty acid and monoterpenoid biosynthesis pathways, suggesting targeted metabolic responses. While both NPs effectively suppressed BLB, Ag Nps showed superior antimicrobial performance, whereas Zn NPs influenced soil nutrient profiles. These findings underscore the potential of green-synthesized NPs as sustainable alternatives for BLB management, balancing disease control with minimal adverse effects on plant physiology and soil ecosystems.

Using LC–MS/MS-based targeted metabolomics with OPLS-DA and KEGG analysis, we identified 14 differentially expressed metabolites (8 up-/6 down-regulated) in Se-exposed plants. These metabolites mapped to glycolysis, TCA cycle, pentose phosphate pathway, electron transport chain, and amino acid/pyruvate metabolism. Activity assays of key enzymes, including PGI, SDH, G6PDH, 6PGDH, and CCO, revealed potential multi-pathway perturbations in energy metabolism under Se treatment.</p><h3>Conclusions</h3><p>Based on these results, it can be concluded that selenium addition significantly affected amaranth energy metabolism.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":512,"journal":{"name":"Chemical and Biological Technologies in Agriculture","volume":"12 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chembioagro.springeropen.com/counter/pdf/10.1186/s40538-025-00845-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
