arrA gene amplicons during soil incubation
Effects of four treatments (control, rice straw addition, gypsum addition, and hematite addition) on the redox-controlled cadmium and arsenic mobility in a paddy soil were investigated via an incubation experiment. Soil were sampled at different time points. Soil chemical properties were determined and soil DNA extracted. Amplicons of the arrA gene, which is involved in dissimilatory arsenic reduction, were sequenced on a Illumina MiSeq platform. The arrA gene was amplified with the primer set arrA-CVF1/arrA-CVR1 (Mirza et al. 2017).
