Summary: The presence of Enterobacter sp. E1 significantly affects the accumulation of arsenic in Pteris vittata by promoting plant growth and dissolving soil arsenic. The strain E1 increases the water-soluble and exchangeable arsenic while reducing the Fe-bound arsenic in the soil. Additionally, the strain E1 has a positive effect on microbial diversity and soil enzymatic activities with low ecological risks.

Summary: The behaviors of antimony (Sb) and arsenic (As) in plants were examined in two As-hyperaccumulators P. vittata and P. cretica. Both plants showed improved growth under Sb exposure, with P. cretica performing better. Sb accumulation was mainly concentrated in the roots for both plants, with differences in Sb speciation between the two species.

Summary: Arsenic is a toxic heavy metal that is widely present in the environment and can severely harm water resources. Bioremediation is a sustainable and cost-effective technology for removing toxic compounds. The resistance of Deinococcus indicus, an arsenic resistant bacterium, to cellular insults was extensively characterized to explore its potential use in arsenic bioremediation.

Summary: Selenate treatment can enhance arsenic (As) accumulation in the hyperaccumulator plant Pteris vittata, mainly by promoting reduction of AsV to AsIII, translocation of AsIII from roots to fronds, and sequestration of AsIII into vacuoles in the fronds. This finding suggests that selenate may be used to enhance phytoremediation of As-contaminated soils using P. vittata.

Summary: This study isolated and identified six arsenic-resistant bacteria from the drying Urmia lake, which showed high tolerance to arsenate and arsenite. These strains harbored the arsenate reductase gene (arsC) but lacked the respiratory arsenate reductase gene (arrB) and arsenite oxidase gene (arxA). The study provides potential bacteria for bioremediation practices and reveals arsenic contamination in Urmia lake.

Summary: This study investigated the metabolomic correlation of P. vittata and associated rhizospheric microorganisms during As phytoextraction. The results demonstrate that the plant is the major driving force of rhizospheric microbiota generation, and both microbial community and metabolites in rhizosphere of P. vittata correlate to increased bioavailable As. Multi-omics analysis revealed that pterosins enrich microbes that potentially promote As phytoextraction.

Summary: Arsenic contamination affects the composition and function of rhizosphere microbial communities, which in turn influences the growth and arsenic absorption ability of P. vittata. As soil arsenic levels increase, the suitability of soil microbes for P. vittata growth decreases, resulting in increased abundance of pathogenic fungi and parasitic bacteria and decreased abundance of symbiotic fungi.

Summary: In this review, the beneficial effects of arsenic (As) in P. vittata, including growth promotion, elemental defense, and other potential benefits, are highlighted. The mechanisms of As coping in P. vittata, such as uptake, reduction, efflux, translocation, and sequestration/detoxification, are also discussed. It is hypothesized that P. vittata has evolved strong capacities for As uptake and translocation to obtain beneficial effects, leading to the accumulation of high As concentrations.

Summary: Recycling arsenic-rich biomass of Pteris vittata is a critical issue in phytoremediation, but extracts of P. vittata have valuable bio-activities and compositions, offering a new solution for recycling. A pilot-scale experiment successfully demonstrated the extraction of phenolic compounds from 1 ton of biomass, yielding a high-value extract with low production waste cost.

Summary: This study aims to characterize the root endophytic community composition and As-metabolizing potentials in P. vittata. Results showed that microbial As(III) oxidation was the dominant As-biotransformation process in P. vittata roots, and members of Rhizobiales were the core microbiome and the dominant As(III) oxidizers.

Summary: This study investigated the accumulation and distribution of arsenic (As) in young fronds of Pteris vittata using mu-XRF technique. It was found that the As content in young fronds increased linearly up to 60 days and gradually distributed from the apex to the base of the fronds. In whole plantlets, As was detectable in the apex of a few fronds and fiddleheads from 9 to 20 days, and later localized in all fronds, the rhizome, and the basal part of the roots. The study also revealed the correlation between As content and the expression of As-related genes.

Summary: The fern Pteris vittata has demonstrated effective phytoextraction of arsenic from a natural arsenic-rich soil, reaching a high concentration of arsenic in its fronds within 5.5 months. The bacterial consortium found in the rhizosphere of P. vittata is different from those typically found in arsenic-polluted soils, with strains exhibiting high arsenic resistance and the presence of arsenate reductase genes.

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: Intercropping hyperaccumulators with crops is a promising method for remediating arsenic-contaminated soil. The response of intercropping hyperaccumulators with legume plants to different gradients of As-contaminated soil was studied. Results showed that soil As concentration significantly influenced the As uptake by plants. Intercropping Pteris vittata with Sesbania cannabina increased As accumulation, while intercropping with Cassia tora decreased it. The As concentrations in the seeds of both legume plants met the national food standards.

Summary: This study found that long-term exposure to arsenic, lead, and cadmium in drinking water, at concentrations equivalent to the China provisional guideline values, can lead to a decrease in weight gain in male mice. Additionally, this exposure can cause a reduction in protective bacteria (Akkermansia) and an increase in chronic intestinal inflammation in male mice.
