Summary: This study investigates the effect of CeO2 nanoparticles on plant growth and soil microbial communities. The research found that Ce accumulates in cucumber tissues after exposure to CeO2 nanoparticles, with a transformation of CeO2 nanoparticles occurring in the rhizosphere soil. CeO2 nanoparticles treatment induces oxidative stress in roots, but also increases root biomass. Soil enzymatic activity and microbial community were also altered, with more prominent changes observed in the rhizosphere soil. The study suggests that the release of Ce3+ from CeO2 nanoparticles contributes to their impacts on soil health and plant physiology.

Summary: Rhizosphere-enriched microbes induced by foliar phytopathogen infection can assemble into a functional community to enhance plant defense mechanisms. In this study, the changes in rhizosphere bacterial communities in tomato plants infected with Botrytis cinerea were investigated. Specific rhizosphere bacterial taxa were recruited by the phytopathogen-infected plants, while several bacterial taxa stably colonized the rhizosphere regardless of phytopathogen infection. A synthetic community consisting of 8 phytopathogen-inducible and 30 stably-colonizing bacteria species were established through the analysis of the rhizosphere bacterial community.

Summary: In a greenhouse study, the effects of Tuber indicum (Chinese black truffle) and T. lijiangense (Chinese white truffle) colonization on Castanopsis rockii host growth, physiological responses, and mycorrhizosphere bacterial communities were compared. Both truffle species increased leaf photosynthetic rate, leaf P concentration, acid phosphatase activity, and bacterial richness of the mycorrhizosphere. However, T. indicum colonization decreased tartrate content, bacterial acid phosphatase, phoC gene abundance, and peroxidase (POD) activity of ectomycorrhizal root tips, but increased mycorrhizosphere pH and superoxide dismutase (SOD) of ectomycorrhizal root tips compared to T. lijiangense colonization. Mycorrhizosphere bacterial community composition also differed significantly between the two truffle species. The bacterium Agromyces cerinus showed a significant correlation with acid phosphatase activity and leaf P concentration, indicating its potential role in phosphorus mobilization and acquisition.

Summary: Loss of crop yield to pathogen damage seriously threatens efforts to achieve global food security. In this study, La-based nanomaterials with different morphologies and compositions were investigated for their control of bacterial pathogen Ralstonia solanacearum on tomato. Foliar application of LaPO4 nanorods significantly suppressed pathogen infection, and the disease control efficacy of different La-based nanomaterials varied. Mechanistically, LaPO4 nanorods supplied low levels of La ions to activate calmodulin and enhance phenylalanine ammonia lyase activity and pathogenesis-related gene expression. Additionally, La-based nanomaterials increased flavonoid and polyphenol content and antioxidative enzyme activity, reducing oxidative stress in tomato shoots. The higher disease control ability of LaPO4 nanorods was attributed to its bioavailability, slow-release ability, and P nutrient supplement. These findings highlight the importance of tuning nanomaterial morphology and composition for optimal sustainability and efficacy.

Summary: In this study, the degradation behavior of glyphosate in Vulpia myuros cultivated in a hydroponic system was investigated. The results showed that V. myuros could absorb glyphosate, and the concentration of glyphosate in the plant decreased over time. The degradation dynamics of glyphosate fitted a first-order kinetic model, with a half-life of 5.08 days. The content of the glyphosate metabolite did not change significantly over time. These findings suggest that V. myuros has the potential to be used as a remediation plant for environmental restoration.

Summary: This study found that the heme homeostasis signal participates in inducing a protective response when controlling nanopolystyrene toxic effects in the parental generation. However, its role in the regulation of transgenerational toxicity of nanopolystyrene toxicity is unclear. Using Caenorhabditis elegans as a model organism, it was discovered that nanopolystyrene particles downregulated the glb-18 gene expression in both the parental generation and the offspring. Lower levels of GLB-18 led to increased susceptibility to transgenerational toxicity of nanopolystyrene. Importantly, germline GLB-18 activated the downstream intestinal HRG-4/HRG-1/ATFS-1/HSP-6 pathway to control the transgenerational toxicity of nanopolystyrene. These findings suggest a possible association between changes in heme homeostasis signal and transgenerational nanoplastic toxicity within organisms.

Summary: In this study, the role of nitrogen-doped carbon dots (N-CDs) in enhancing maize drought tolerance was investigated. Greenhouse experiments showed that foliar application of N-CDs significantly increased the net photosynthesis rate and the fresh and dry weights of roots and shoots under drought stress. N-CDs exhibited ROS-scavenging activity, upregulated psbA gene expression, and promoted fast synthesis of the D1 protein to repair photosystem II under drought stress. Furthermore, long-term experiments demonstrated that N-CD exposure reduced corn yield loss by nearly 30% compared to the control groups. This study revealed that N-CD-enabled nanoagriculture has the potential to ensure crop growth and yield under drought stress, providing a promising alternative to cope with global climate change.
