Fungal microbiota (ITS2 metabarcoding) of extraction control
DNA extraction was performed using the DNeasy PowerSoil Pro Kit (Qiagen, Germany) without a sample. Illumina NovaSeq 6000 sequencing with a paired-end approach (250 bp) was conducted targeting the fungal ITS2 region (primer pair ITS3-2024F/ITS4-2409R).
