title: 16S rDNA-Seq: SY agricultural soil
design: The total community DNA was extracted from soils by use of a MoBio Power Soil DNA extraction kit. The V3V4 region of the 16S rRNA gene was amplified in triplicate using the barcoded 341F and 806R primer set. PCR products were quantified, purified and sequenced by Illumina Hiseq 2500 platform for assessment of bacterial diversity and community structure.
