Summary: The study found that bacterial inoculation stimulates the formation of iron plaque on the root surface of rice plants and has an impact on the elemental content of the plaque, plant growth, and cadmium content. In particular, inoculation with YGL bacteria can help reduce the cadmium content in rice grains.

Summary: The addition of Fe2+ (3 mM) was found to reduce the adsorption of CuO NPs (100 mg L-1) by rice plants, leading to a decrease in Cu uptake and accumulation in roots and shoots. Fe2+ induced the formation of iron plaque and altered metabolite levels, resulting in less Cu accumulation in rice plants exposed to NPs.

Summary: The addition of S fertilizer (S-0) increased rice plant biomass and iron plaque formation, reduced Cd concentration in rice grains, and affected the bacterial community in rice rhizosphere soil. This suggests that promoting specific bacterial groups in the soil through S-0 application may play a role in reducing Cd risk in the soil-rice system.

Summary: The use of rice straw and rape straw biochars can effectively reduce the concentration of cadmium in soil and decrease its uptake by rice plants. Rape straw biochar is more effective in reducing cadmium concentration in rice roots and improving soil properties. Biochar also prevents the transportation of cadmium from soil to rice roots by forming iron plaques.

Summary: In this study, the uptake, translocation and subcellular distribution of neonicotinoid insecticides, triazole fungicides, and sulfonylurea herbicides in rice plants were investigated. It was found that neonicotinoids were mainly concentrated in the leaves, triazoles were mainly concentrated in the roots, and sulfonylurea herbicides were first transported upward through the apoplastic pathway. The subcellular distribution of pesticides was influenced by their molecular structures.

Summary: Exposure to cadmium (Cd) leads to severe leaf chlorosis and reduced nutrient uptake. This study investigated how plants respond to Cd stress in the roots and its relationship to leaf chlorosis. The results showed that Cd disrupted the balance of multiple nutrient elements at different levels, particularly Mn and Fe which declined by 96% and 89% respectively, leading to leaf chlorosis. Plants actively downregulated the expression of metal transporters to reduce Cd uptake, but this also resulted in reduced uptake of Fe and Mn. Additionally, Cd stress promoted the formation of iron plaque, reducing exchangeable ions on the root surface. Importantly, ethylene played a crucial role in regulating iron plaque formation and the forms of Cd. Blocking ethylene biosynthesis increased exchangeable Cd on the root surface and decreased the percentage of iron oxides bound Cd, leading to increased Cd accumulation in the shoots. In summary, this study revealed that plants actively control the expression of metal transporters and ethylene-dependent iron plaque formation to reduce Cd uptake but sacrifice iron nutrition. The mechanism of ethylene-sequestered Cd in the rhizosphere in response to Cd stress may provide guidelines for mitigating Cd accumulation in rice.

Summary: This study investigates the effects and mechanisms of elevated CO2 concentration on cadmium (Cd) uptake by rice in a 3-year experiment. The results show that increased CO2 concentration leads to higher levels of dissolved Fe2+ in soil, resulting in more low-crystalline Fe oxides being deposited on the root surface. This inhibits the uptake of Cd by rice.

Summary: The synthesized alpha-MoO3 and MoS2 NPs had nanosheet and nanoflower-like structures with different crystallite sizes. The uptake and bioaccumulation of Mo-NPs in rice seedlings were tissue-specific, and the impact of the nanoparticles showed stimulation of repair mechanisms at low doses but oxidative imbalance at higher concentrations. MoS2 NPs were found to be more environmentally safe compared to alpha-MoO3 NPs, with low translocation and accumulation with no significant impact on rice growth at 100 ppm concentration.

Summary: Oxygen nanobubble-loaded biochars have been found effective in reducing copper toxicity in paddy soils and improving crop productivity. This amendment improves the redox potential and dissolved oxygen concentration in the rhizosphere, promotes root iron plaque formation, and inhibits copper influx. It also enhances soil microbial diversity and increases bacterial genes abundance involved in copper complexation and export. The sequestered copper in root iron plaque and soil bacteria prevents its accumulation in edible parts of the plants.

Summary: This study quantified the uptake and size distribution of CeO2, La2O3, Fe3O4, and MnFe2O4 nanoparticles (NPs) in five different plants. The results showed that all four types of NPs were taken up by the plants, and their size distribution varied in different plant parts. Amaranth had the highest particle concentration, while kidney beans had the highest concentration of Fe (MnFe2O4)-based NPs. In addition, in vitro digestion experiments revealed that these NPs may be accessible to the human system.

Summary: This study investigated the influence of phosphorus (P) on the formation of iron plaque on rice roots and its impact on cadmium (Cd) uptake. The results showed that while P supply enhanced the formation of iron plaque, it reduced the retention capability of Cd. Excessive P fertilizer application can lead to increased accumulation of Cd in rice plants.

Summary: The study found that nano hydroxyapatite, iron oxide nanoparticles, and nano zero valent iron can significantly reduce the accumulation of cadmium in rice and promote plant growth. These nanoparticles reduce cadmium content through adsorption and the formation of iron plaques, and alleviate oxidative damage by regulating hormones, metal ion balance, and gene expression. This study provides a theoretical basis for using nanoparticles to reduce cadmium accumulation in edible plants.

Summary: This study developed a synergistic system of P. oxalicum SL2-nZVI for Cr(VI) remediation, which effectively removed Cr(VI) mainly through extracellular nonenzymatic reduction. P. oxalicum SL2 exhibited iron precipitate solubilization and Fe(II) regeneration capabilities, and iron ions generated by nZVI also stimulated Cr(VI) reduction by organic acids secreted by P. oxalicum SL2. Overall, the P. oxalicum SL2-nZVI synergistic system shows promise for regenerating Fe(II) while reducing Cr(VI).

Summary: Cyanide tailings, a type of solid waste generated by gold mining, require decyanation treatment due to their highly toxic nature. The traditional decyanation methods have limitations in terms of treatment effects and costs. This study proposed enhancing the cyanide treatment effect through natural degradation methods such as raising the temperature, increasing UV irradiation, and turning the pile periodically. By applying these modifications, the cyanide tailings met the standards for discharge and use in building materials while reducing treatment costs by over 50%.

Summary: The increasing use of nanomaterials in agriculture poses environmental risks, but the impact of nanomaterials on plant proteins is still not well understood. This study investigated the effects of CuO nanoparticles (NPs), CuO bulk particles (BPs), and dissolved Cu ions on rice seedlings. The results showed that CuO NPs had greater Cu accumulation, higher ascorbate peroxidase activity, and altered protein expression compared to BPs and Cu ions. Specifically, proteins related to C2 domain, glutathione S-transferase, drug metabolism, ion transport, oxidative phosphorylation, and phagosome pathways were significantly affected by NPs. This proteomic analysis suggests that CuO NPs caused higher phytotoxicity and activated defense responses in rice seedlings.
