| Title | A strategic framework for efficient arsenic phytoextraction by Pteris vittata: Integrating rhizosphere management with field-scale practices |
| Journal | Journal of Environmental Chemical Engineering |
| Abstract |
The pervasive threat of arsenic (As) contamination to global health and food security demands effective remediation solutions, yet the practical application of the pioneer As-hyperaccumulator Pteris vittata is often constrained by its field performance, which is governed by a complex interplay of overlooked environmental and biological factors. To address this gap, this review systematically synthesizes the fundamental mechanisms and enhancement strategies for Pteris vittata-based phytoremediation of As. Our analysis establishes that the plant’s efficiency for As removal is not a fixed trait but an emergent property of its holobiont system. Specifically, root uptake, translocation, and vacuolar sequestration of As in plants are profoundly influenced by soil properties (e.g., pH and Eh), nutrient dynamics (e.g., phosphorus and nitrogen), climate conditions (e.g., temperature and precipitation) and crucially, the rhizosphere microbiome. We further reveal a critical physiological trade-off: microbial processes such as arsenite oxidation can mitigate phytotoxicity and promote growth, while arsenate reduction often provides a more direct pathway to enhance As accumulation. The net remediation outcome depends on the functional synergy and competition within the microbial community. In light of these, we provide a comprehensive critical assessment of advanced mitigation strategies, from the precision engineering of synthetic microbial communities to the application of omics-guided tools and machine learning for predictive modeling and optimization. By integrating plant physiology with microbiome science and data-driven analytics, this review proposes a holistic framework to transition Pteris vittata from a proven concept into a predictable, efficient, and scalable phytotechnology. This work provides an indispensable knowledge base and a clear strategic roadmap for leveraging this unique plant-microbe-environment nexus to achieve sustainable environmental restoration of As-contaminated soils and waters worldwide. |
