Summary: The ACR3 genes in arsenic hyperaccumulator Pteris vittata were studied in yeast and tobacco, showing their roles in regulating arsenic translocation and sequestration. PvACR3;2 facilitated AsIII translocation to the shoots and efflux from the roots in tobacco, while PvACR3;3 sequestered AsIII in tobacco root vacuoles.

Summary: In this study, magnesium oxide nanoparticles (MgO NPs) synthesized through a green route were evaluated for their efficacy in reducing arsenic (As) accumulation and phytotoxicity in rice plants. The results showed that the application of MgO NPs significantly reduced As accumulation in the roots and shoots of rice seedlings, and improved their growth and antioxidant defense system activity. These findings suggest the potential use of MgO NPs for mitigating As contamination and improving rice yield.

Summary: This study examined the accumulation of metal(loid)s in the halophyte Juncus acutus from anthropogenically impacted estuaries in NSW, Australia. The results showed that As and other metal(loid)s were primarily accumulated in the roots with limited translocation to the culms. This indicates that Juncus acutus is a useful phytostabiliser and a potential bioindicator for metal(loid) accumulation.

Summary: The study found that low-accumulating cabbage cultivars showed better root activity, cell integrity, root antioxidants, and shoot chlorophyll under arsenic stress. Arsenic was the main factor driving the structure of bacterial communities, and certain bacterial groups correlated positively with arsenic concentrations in high-accumulating cultivars. Low-accumulating cultivars had higher abundance of Patescibacteria in rhizosphere soils, which could immobilize toxic ions in the soil. The interactions between low-accumulating cabbage and bacterial communities under arsenic stress may play a role in plant arsenic uptake.

Summary: The study revealed that the low-Cd-accumulating wheat genotype, AK58, exhibited stronger Cd tolerance and higher antioxidant system capacity in roots compared to the high-Cd-accumulating genotype, ZM10. Additionally, AK58 had higher concentrations of Cd bound to root cell walls, with pectin and hemicellulose playing important roles in Cd binding. Moreover, Cd sequestration in vacuoles was identified as another tolerance mechanism in AK58.

Summary: The study found that higher concentrations of ascorbate were present in leaves, while crowns accumulated more nicotinamide adenine dinucleotide during cold acclimation, deacclimation, and reacclimation in winter wheat. Constant low temperature conditions during cold acclimation led to increased accumulation of ascorbate and glutathione in plant tissues, whereas prolonged higher low temperature conditions had a negative impact on freezing tolerance.

Summary: The occurrence of arsenic in groundwater and its accumulation in rice grains is a global health concern. This study found that utilizing alternate wetting and drying (AWD) irrigation with temporarily stored groundwater (TSG) can effectively reduce arsenic content in rice grains. The research also highlights the importance of irrigation management and rice variety selection in minimizing arsenic accumulation in rice grains.

Summary: Efflux is important for maintaining low intracellular accumulation only in actively growing cells, while envelope permeability is the predominant factor in stationary-phase cells. This study suggests that antibiotics with intracellular targets may be less effective in complex infections with nongrowing or slow-growing bacteria, and efflux inhibitors may potentiate the activity of existing antibiotics in actively growing bacterial infections. The remodeling of the cell envelope prior to stationary phase could provide novel drug targets.

Summary: Recent years have seen an increase in research utilizing nanoparticles to potentially reduce the toxicity of metals/metalloids in plants. In this study, the effects of different concentrations of zinc oxide nanoparticles (ZnO-NPs) on the toxicity of arsenic (As) and mercury (Hg) in Pleioblastus pygmaeus plants were investigated. The results showed that ZnO-NPs increased antioxidant activity, reduced accumulation of As and Hg, adjusted stomatal closure, and ultimately detoxified the plants. Further research is needed to understand the effects of different metals/metalloids.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
