“…Second, arsenic pollution may increase the amount of root exudates from P. vittata (Das et al, 2017), which may enhance the selective effect of plants on bacterial and fungal communities through the "rhizosphere effect," thereby reducing microbial diversity in the rhizosphere. Third, soil arsenic pollution significantly reduced plant P concentration (Supplementary Figure S3), possibly by competing with P for the phosphate transporter in P. vittata roots (Wang et al, 2002;Wu et al, 2022b), which is likely to further impact the microbial community in the rhizosphere of P. vittata.…”

“…There are several possible explanations for these results. First, soil arsenic pollution significantly hindered the absorption of P by P. vittata (Supplementary Figure S3), possibly due to competition between arsenic and P for the phosphate transporter in P. vittata roots (Wu et al, 2022b). Laliberté et al (2015) found a trade-off for plants in soil P acquisition and resistance to soil-borne pathogens.…”

Arsenic contamination causes numerous health problems for humans and wildlife via bioaccumulation in the food chain. Phytoremediation of arsenic-contaminated soils with the model arsenic hyperaccumulator Pteris vittata provides a promising way to reduce the risk, in which the growth and arsenic absorption ability of plants and the biotransformation of soil arsenic may be greatly affected by rhizosphere microorganisms. However, the microbial community composition in the rhizosphere of P. vittata and its functional role in arsenic phytoremediation are still poorly understood. To bridge this knowledge gap, we carried out a field investigation and pot experiment to explore the composition and functional implications of microbial communities in the rhizosphere of four P. vittata populations with a natural arsenic contamination gradient. Arsenic pollution significantly reduced bacterial and fungal diversity in the rhizosphere of P. vittata (p < 0.05) and played an important role in shaping the microbial community structure. The suitability of soil microbes for the growth of P. vittata gradually decreased following increased soil arsenic levels, as indicated by the increased abundance of pathogenic fungi and parasitic bacteria and the decrease in symbiotic fungi. The analysis of arsenic-related functional gene abundance with AsChip revealed the gradual enrichment of the microbial genes involved in As(III) oxidation, As(V) reduction, and arsenic methylation and demethylation in the rhizosphere of P. vittata following increased arsenic levels (p < 0.05). The regulation of indigenous soil microbes through the field application of fungicide, but not bactericide, significantly reduced the remediation efficiency of P. vittata grown under an arsenic contamination gradient, indicating the important role of indigenous fungal groups in the remediation of arsenic-contaminated soil. This study has important implications for the functional role and application prospects of soil microorganisms in the phytoremediation of arsenic-polluted soil.

In this study, we sought to identify a soil stabilizer that can be applied to paddy fields vulnerable to arsenic (As) pollution. To this end, we conducted a pot experiment in which we evaluated the effects of different stabilizers on the bioavailability of As in paddy soil. As candidate stabilizers, we assessed calcium superphosphate (CSP), sulfur, and steel slag, which were applied at the rates of 0.7 and 1.4, 0.1 and 0.2, and 7.0 and 14.0 Ma ha −1 , respectively. On day 67 after rice transplantation, we detected significantly lower concentrations of As in the solutions of paddy soil treated with 1.4 Ma ha −1 CSP (96.9 µg L −1 ) and 0.2 Ma ha −1 sulfur (207.2 µg L −1 ) compared with the As concentrations in control (314.5 µg L −1 ) and steel slag-treated (268.6-342.4 µg L −1 ) soil. Compared with the As concentrations in control brown rice (0.16 mg kg −1 ), concentrations in brown rice were lowest in the pots treated with 1.4 Ma ha −1 CSP (0.09 mg kg −1 ). Furthermore, in response to CSP treatments, we detected increases in the weight of rice grains (50.0-50.4 g/pot) compared with the control (40.4 g/ pot) and other treatments (26.9-48.1 g/pot), which we speculate could be attributed to the reduction in As toxicity to rice owing to a decline in soil solution As contents and the fertilization effect of the CSP treatment. Collectively, our findings indicate a high-level application of CSP (1.4 Ma ha −1 ) to paddy soil has a comparatively beneficial effect in mitigating the bioavailability of As.
