AM Fungal Sequencing Data from Grassland Extreme Drought Experiment

Arbuscular mycorrhizal (AM) fungal communities were characterized using a meta-barcoding approach. The small subunit ribosomal RNA (SSU rRNA) region was amplified with the barcoded primer pair WANDA/AML2. Amplicons were sequenced using paired-end sequencing (2 × 300 bp) on the Illumina MiSeq platform. Sequence data were processed with the DADA2 denoising algorithm to generate amplicon sequence variants (ASVs). Taxonomic assignment of AM fungal sequences was performed via BLAST searches against the MaarjAM database.
