Summary: This study found that different forms of biochar have varying effects on plant growth, with biochar extract showing a positive promotion on seedling growth while bulk biochar had a negative impact on root growth. The response to biochar also differed between crop genotypes. The study suggests that the presence of low molecular weight organic acids and nanoparticles in biochar DOM may contribute to these effects.

Summary: Phytochelatins (PCs) are crucial in heavy metal detoxification in plants, and a PCS gene, BnPCS1, was identified in ramie. BnPCS1 is induced by cadmium and abscisic acid, and overexpressing it in plants showed improved growth, lower oxidative stress, and enhanced cadmium accumulation, suggesting its potential in phytoremediation of Cd-contaminated soils.

Summary: This study demonstrates that supplementation of sulfur can alleviate cadmium toxicity in alfalfa plants by restoring biomass, chlorophyll synthesis, and protein concentration, as well as enhancing photosynthetic kinetics and membrane stability. The mechanisms involve upregulation of sulfate transporters, glutathione and phytochelatin synthesis, and subcellular sequestration of excess cadmium in roots under sulfur surplus conditions. These findings provide valuable insights for developing cadmium-free forage crops through sulfur application and breeding/transgenic experiments.

Summary: The addition of biochar increases the colonization rate of arbuscular mycorrhizal fungi (AMF) and significantly improves maize growth and phosphorus uptake. Biochar mainly enhances phosphorus uptake by regulating root morphology and plant phosphorus content, whereas AMF enhances microbial activity and phosphatase activity, leading to more efficient phosphorus uptake by maize, especially under water stress conditions.

Summary: This study aimed to investigate the effects of different concentrations of growth regulators on cotton root morphological parameters and enzyme activities, and to find suitable plant growth regulators and their optimal concentrations to improve cotton seedling growth. The results showed that different concentrations of growth regulators had different effects on the root growth and enzyme activities of different cotton varieties. Principal component analysis revealed that 0.10 mmol/L SA was the optimal treatment for promoting the development of Z619 roots, while 0.050 mmol/L SA was the optimal treatment for promoting the development of Z27 and Z39 roots.

Summary: This study found that subsurface drip irrigation significantly reduced the cadmium content in roots, shoots, and fruits, increased yield, and improved root growth and activity in soil at a depth of 20-40 cm compared to other treatments, although the cadmium concentration in the rhizosphere was not significantly decreased. The microbial population and enzyme activities in the rhizosphere of subsurface drip irrigation and alternate-rows irrigation were basically higher than that of surface drip irrigation and conventional furrow irrigation.

Summary: In this study, black bone (BB), biochar (BC), silicon fertilizer (SI), and leaf fertilizer (LF) were evaluated for their effects on decreasing soil cadmium (Cd) availability and uptake in wheat plants grown in Cd-contaminated soils. Results showed that all amendments significantly reduced soil Cd bioavailability and plant Cd uptake, leading to improved wheat growth and yield. Significant effects were observed with SI showing the highest decrease in both soil Cd bioavailability and plant Cd uptake, likely due to alterations in soil microbial community and bioavailable silicon.

Summary: The impact of reclaimed wastewater irrigation on the spread of antibiotic resistance genes in soil is influenced by various biotic and abiotic factors, with cropping system having a greater effect on the profile of ISs and resistance genes than irrigation. Most ARGs co-occurred with metal and biocide resistance genes through efflux pumps, emphasizing the importance of understanding and enhancing crop management for mitigating ARG dissemination in RW-irrigated soils.

Summary: This study investigates the adsorption processes and mechanisms of antibiotics on roots in the plant-soil system under different environmental conditions. It finds that the electrochemical properties of roots play a significant role in antibiotic adsorption. Coexisting low-molecular weight organic acids and anions inhibit antibiotic adsorption on roots. Soybean roots show stronger adsorption ability compared to maize and wheat roots. This research highlights the importance of electrochemical interactions between antibiotics and roots, contributing to accurate risk assessment and effective pollution control of antibiotics.

Summary: Due to climate change, water shortages will affect 2/3 of the world's population by 2025, while a 50% increase in food production is needed by 2050 to feed nine billion people. Anthropogenic activities have also resulted in increased water pollution. Wastewater reuse for irrigation is a global solution, but it can lead to soil pollution and heavy metal accumulation. This study discusses the status of water availability, wastewater treatment and reuse, and potential health risks in China, emphasizing the need for proper treatment to mitigate adverse impacts on human health and the environment.

Summary: This study investigated the effects of different irrigation waters on the sorption and mobility of Cd in cropland soil. The results showed that irrigation with reclaimed water and livestock wastewater reduced the Cd adsorption capacity of soil, with livestock wastewater having a more significant impact. Although these results were obtained from a rhizobox experiment, they strongly suggest that the altered Cd adsorption and desorption behavior caused by reclaimed water and livestock wastewater irrigation may pose risks to farmland ecosystems and deserve more attention.

Summary: The effects of root exudates and irrigation with treated wastewater on heavy metal mobility and soil bacterial composition under intercropping were investigated in this study. The results showed that application of root exudates increased plant growth and soil nutrient content. Intercropping had a greater impact on reducing heavy metal migration in the soil-plant system compared to monocropping. Appropriate application of root exudates could potentially improve plant growth and soil health, and reduce toxic heavy metal concentrations in soils and plants irrigated with treated wastewater.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
