title: Hyphal ingrowth core soil microbiome (16S rRNA gene profile)
design: DNA was extracted from hyphal ingrowth core soils with the Dneasy PowerSoil Pro kit. A subset of samples was fractionated in a cesium chloride density gradient. The V4 region of the 16S rRNA gene was amplified with the 515F/806R primer pair and processed and barcoded through the Illumina V2 PE150 sample preparation kit.
