title: Environmental sample from Sweden, Oland, isolate OM, soil
design: Soil DNA was extracted using the PowerMax Soil DNA Isolation Kit (MoBio Laboratories, Inc.) from a 5 g subsample of soil which was collected from each site and used for setting up the drought experiment. To characterise the soil fungal community composition, we amplified the target marker region of the ribosomal ITS2 using the degenerate primer pair fITS7:fiTS7o. The amplified ribosomal ITS2 regions were sequenced by Novogene Company (UK) using a 2  250 bp paired-read sequencing approach on an Illumina NovaSeq platform.
