Rhizosphere reprogramming by phosphate slag enhances glutathione-centered redox regulation and root development in tobacco

Project description:Background and aims: Phosphate slag, a by-product of phosphorus and steel production, is a potential soil amendment that improves nutrient availability and redox stability. However, how it reshapes the rhizosphere microbiome and metabolism to promote tobacco (Nicotiana tabacum L.) root development remains unclear. This study aimed to elucidate the mechanisms by which phosphate slag reprograms rhizosphere microbial and metabolic networks, focusing on glutathione-centered redox regulation and carbon flux balance.Methods: Metagenomic sequencing and untargeted metabolomics were integrated with soil and plant trait analyses in two tobacco-growing regions of Yunnan, China-Jiuxiang and Gengjiaying. Three treatments were tested: control (C), phosphate slag (P), and phosphate slag plus microbial conditioner (PM).Results: Phosphate slag markedly reprogrammed the rhizosphere microbiome and metabolome, enriching taxa and pathways related to glutathione and ascorbate-aldarate metabolism, which enhanced antioxidant buffering and redox balance. Activation of the pentose phosphate pathway (PPP) supplied NADPH for glutathione recycling but reduced TCA flux and ATP synthesis, producing thicker but shorter roots. Increased siderophore and amino acid metabolism indicated improved nutrient mobilization. Multi-omics integration revealed coordinated microbe–metabolite interactions-microbes linked to potassium traits (TP, K₂O) and metabolites to sugar and alkaloid pools (TS, RS, TPA). Validation in Gengjiaying confirmed the reproducibility of these responses.Conclusion: Phosphate slag enhances tobacco root growth by strengthening glutathione-mediated redox regulation and nutrient cycling. Yet, excessive PPP activation or microbial competition may limit energy supply. Balancing carbon and nutrient fluxes could optimize slag’s agronomic benefits and promote sustainable soil management.

Rice plants treated with Spirulina-derived biochar optimize resource allocation towards seed production

Project description:The use of biofertilizers is becoming an economical and environmentally friendly alternative to promote sustainable agriculture. Biochar from microalgae can be applied to enhance the productivity of food crops through soil improvement, slow nutrient absorption and release, increased water uptake, and long-term mitigation of greenhouse gas sequestration. Therefore, the aim of this study was to evaluate the stimulatory effects of biochar produced from Spirulina platensis biomass on the development and seed production of rice plants. Biochar was produced by slow pyrolysis at 300°C, and characterization was performed through microscopy, chemical, and structural composition analyses. Molecular and physiological analyses were performed in rice plants submitted to different biochar concentrations (0.02, 0.1, and 0.5 mg mL-1) to assess growth and productivity parameters. Morphological and physicochemical characterization revealed a heterogeneous morphology and the presence of K and Mg minerals in the biochar composition. Chemical modification of compounds post-pyrolysis and a highly porous structure with micropores were observed. Rice plants submitted to 0.5 mg mL-1 of biochar presented a decrease in root length, followed by an increase in root dry weight. The same concentration influenced seed production, with an increase of 44% in the number of seeds per plant, 17% in the percentage of full seeds per plant, 12% in the weight of 1,000 full seeds, 53% in the seed weight per plant, and 12% in grain area. Differential proteomic analyses in shoots and roots of rice plants submitted to 0.5 mg mL-1 of biochar for 20 days revealed a fine-tuning of resource allocation towards seed production. These results suggest that biochar derived from Spirulina platensis biomass can stimulate rice seed production.

Fulvic acid exhibits antitumor effects in ovarian cancer cells by upregulating CYP1A1 expression

Project description:Humic substances are a mixture of natural organic macromolecular compounds, mainly fulvic acid (FA) (soluble in alkali, water, and acid) and humic acid (soluble in alkali but insoluble in water and acid). However, to the best of our knowledge, its antitumor effect remains indeterminate. Herein, we aimed to explore the effects and mechanisms of FA in ovarian cancer cells.

Transcriptional characterization of maize roots in response to nitrate (NO3-), Water-Extractable Humic Substances (WEHS) and NO3-+WEHS.

Project description:Soil humic substances are known to positively influence plant growth and nutrition. In particular, low-molecular fractions have been shown to increase NO3- uptake and PM H+-ATPase activity and alter expression of related genes. Changes in maize root transcriptome due to treatment with nitrate (NO3-), Water-Extractable Humic Substances (WEHS) and NO3-+WEHS were analyzed.

Changes in gene expression when the redox potential of steady state cultures of Staphylococcus aureus is lowered by addition of dithiothreitol

Project description:Staphylococcus aureus can survive in the low redox potential environment of the host cytosol. How low redox potential affects S. aureus USA300 Je2 was investigated by establishing aerobic steady state chemostat cultures and then perturbing the steady state by addition of the reducing agent dithiothreitol. These highly controlled steady state cultures allowed only one parameter (redox potential) changed. Dithiothreitol was used as a non-metabolizable reductant. Before and after perturbation samples were taken for gene expression profiling. Three independent biological replicates were analyzed.
