AM fungal DNA seq: BIGI_S_515
DNA was extracted from homogenized soil samples using the PowerSoil Pro DNA extraction kit. Samples were then processed with metabarcoding amplification and Illumina NovaSeq Sequencing through the University of Tennessee, Knoxville Sequencing Core facility. AM fungi were amplified from the 18S rDNA region using AM fungal-specific primers NS31-AML2 nested within general eukaryotic primers NS1- NS47
