Jia et al. 2022 — Pteris vittata rhizosphere microbiome and arsenic phytoremediation

This study profiled the rhizosphere microbial community of the arsenic hyperaccumulator Pteris vittata across a natural soil arsenic contamination gradient and examined its functional role in arsenic phytoremediation. It is upstream mechanism and microbiome evidence on the soil-to-plant transfer of arsenic; it reports no retail food occurrence and is context-only for Heavy Metal Index purposes.

Key numbers

• Arsenic pollution significantly reduced rhizosphere bacterial and fungal diversity (p < 0.05) and shaped community structure.
• With increasing soil arsenic, suitability of the soil microbiome for P. vittata growth declined: pathogenic fungi and parasitic bacteria increased while symbiotic fungi decreased.
• Arsenic-related functional gene abundance (assayed with AsChip) was progressively enriched along the contamination gradient.

Methods (brief)

Field survey of four P. vittata populations along an arsenic gradient plus a pot experiment; rhizosphere bacterial/fungal community composition by amplicon sequencing and arsenic-cycling functional genes by AsChip.

Implications

Certification: Contributes nothing to HMT&C threshold pools. Mechanism/microbiome context on arsenic mobility and microbial mediation; route as exposure/mechanism context to Soil-to-plant transfer of heavy metals, Arsenic, Total, and Agronomic mitigation.

Courses: Shows how soil arsenic load reshapes the rhizosphere microbiome that supports hyperaccumulator phytoremediation.

App: No contamination_profile blocks are touched.

Microbiome: Core WikiBiome federation signpost — rhizosphere community structure and arsenic-cycling genes under an arsenic gradient.

Verification notes

• Evidence tier B: primary field+pot study in a peer-reviewed journal (Frontiers in Microbiology, CC BY 4.0).
• Page grounded in the published abstract and bibliographic metadata; values preserved as printed. Full-text extraction can follow on synthesis.
• metals: [tAs] — soil/plant total arsenic, not speciated.
• ingredients: [] / products: [] correct: phytoremediation/microbiome context, not retail food occurrence.
• Part 2 direction-of-edit check: adds upstream mechanism/microbiome literature; neutral to HMT&C thresholds, moves toward the literature.
