| 英文摘要 | While soil nutrient heterogeneity is known to influence plant fitness and ecosystem diversity, the ecological effects of heterogeneous arsenic (As) contamination on plant-microbe interactions remain unclear. Using multi-omics, we demonstrate that the As-hyperaccumulator Pteris vittata restores diminished microbial alpha diversity under As heterogeneity. The plant actively forages As by proliferating roots in As-rich patches and altering its root exudate profile. Key exudates, such as phosphocholine and N-acetyl histamine, recruit specific microbial taxa, such as class KD4-96, and order Vicinamibacteraceae, which upregulate As-transforming genes and enhance As mobilization. Rhizobacteria including Blastococcus and Streptomyces also produce auxin, stimulating root growth. Together, these responses form a self-reinforcing feedback loop-linking root foraging, microbial recruitment, As mobilization, and root elongation-that amplifies plant growth and arsenic uptake. Our work establishes a rhizosphere engineering strategy to leverage such plant-microbe feedbacks for improved phytoremediation. |
