“…The rhizosphere soil, as the primary site for ryegrass-microbe coimmobilization of uranium, plays a crucial role in determining the form and structure of uranium as well as the effectiveness of uranium-contaminated soil remediation. 45 To reveal the changes in metabolic pathways induced by different biochar treatments in more detail, the differentially expressed metabolites were classified and counted. The results (Figure 6A−D) showed that the differentially expressed metabolites in uranium-contaminated soil were primarily concentrated in three categories: lipids and lipid-like molecules, organic acids and derivatives, and organic oxygen compounds.…”

The addition of soil amendments to facilitate plantbased remediation of soil contaminated with radioactive nuclides is considered a promising approach. Here, we tested different levels of biochar to help clean uranium-contaminated soil in the potted plants. Adding 1% biochar had the best results in deactivating uranium, increasing soil enzyme activity, and promoting ryegrass growth. Microbiological and metabolomic analysis further revealed that 1 wt % biochar significantly enhanced the abundance of microorganisms such as Actinobacteriota and Myxococcota and accelerated the production of differential metabolites such as lipids and lipid-like molecules, organic acids and derivatives, and organic oxygen compounds. The analysis of biological and nonbiological interaction networks indicates that the coordinated interaction between bacteria, enzymes, and metabolites significantly improves the expression level of the ABC transporter's metabolic pathway. This enhances the resistance of living cells to uranium and maintains system homeostasis under uranium stress. This study provides an example of the application of biochar-assisted phytoremediation and offers theoretical guidance for the remediation of soil contaminated with radioactive nuclides.

BackgroundReductive soil disinfestation (RSD), which involves creating anaerobic conditions and incorporating large amounts of organic materials into the soil, has been identified as a reliable strategy for reducing soilborne diseases in successive cropping systems. However, limited research exists on the connections between soil microorganism composition and plant diseases under various types of organic material applications. This study aimed to evaluate the effects of distinct RSD strategies (control without soil amendment; RSD with 1500 kg ha−1 molasses powder; RSD with 3000 kg ha−1 molasses powder; RSD with 3000 kg ha−1 molasses powder and 37.5–41.3 kg ha−1 microbial agent) on the plant disease index, bacterial community composition and network structure in rhizosphere soil.ResultsRSD treatments significantly reduced the occurrence of black shank disease in tobacco and increased soil bacterial diversity. High amounts of molasses powder in RSD treatments further enhanced disease inhibition and reduced fungal abundance and Shannon index. RSD also increased the relative abundance of bacterial phylum Firmicutes and fungal phylum Ascomycota, while decreasing the relative abundance of bacterial phyla Chloroflexi and Acidobacteriota and fungal phylum Basidiomycota in rhizosphere soil. A multiple regression model identified bacterial positive cohesion as the primary factor influencing the plant disease index, with a greater impact than bacterial negative cohesion and community stability. The competition among beneficial bacteria for creating a healthy rhizosphere environment is likely a key factor in the success of RSD in reducing plant disease risk.ConclusionRSD, especially with higher rates of molasses powder, is a viable strategy for controlling black shank disease in tobacco and promoting soil health by fostering beneficial microbial communities. This study provides guidelines for soil management and plant disease prevention. © 2024 Society of Chemical Industry.
