文摘
- •
Studied arsenite oxidase (aroA-like) & arsenate reductase genes (arsC) in contaminated soils.
- •
aroA-like & arsC genes were amplified from As-hyperaccumulator Pteris vittata rhizosphere.
- •
aroA-like genes were more abundant and biodiversified than arsC genes.
- •
Most bacteria with aroA-like and arsC genes belonged to α-, β- and γ-Proteobacteria.
- •
Arsenate amendment elevated aroA-like gene diversity but reduced arsC gene diversity.
