Rhizosphere Microbiome-Root Exudate Synergy in Pteris vittata: Coordinated Arsenic Speciation and Multielement Metabolic Coupling Drive Hyperaccumulation Efficiency.

ABSTRACT: Rhizosphere microorganisms play a pivotal role in enhancing the arsenic (As) remediation efficiency of Pteris vittata. However, the interactions among rhizosphere microorganisms, root exudates, and As, as well as their influence on As uptake by Pteris vittata at different As concentrations, remain poorly understood. This study systematically elucidates the molecular-ecological mechanisms through which Pteris vittata facilitates arsenic (As) remediation within a multidimensional interaction network. It was found that the rhizosphere microbial community was dominated by Proteobacteria, Acidobacteriota, and Ascomycota, with 44 bacterial and 10 fungal genera identified as genetically conserved core microorganisms. Microbial-mediated arsenic (As) methylation and reduction processes, coupled wit
