Effects of sodium selenate on energy metabolism of amaranth inoculated with Glomus mosseae based on targeted metabolomics
Background
Selenium (Se) deficiency poses significant health risks to human populations globally, necessitating effective biofortification strategies. Amaranth (Amaranthus retroflexus), a nutrient-dense vegetable with demonstrated capacity for Se accumulation in seleniferous soils, represents a promising biofortification vehicle. Critically, arbuscular mycorrhizal fungi (AMF) enhance rhizospheric Se mobilization, yet their synergistic effects on plant energy metabolism remain unexplored.
Results
This pot study investigated the influence of exogenous selenium (Se) treatment on energy metabolism in amaranth colonized by the arbuscular mycorrhizal fungus Glomus mosseae. 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.
Conclusions
Based on these results, it can be concluded that selenium addition significantly affected amaranth energy metabolism.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
