title: Uncultured Glomeromycotina partial 18S rRNA gene, isolate B
design: DNA was extracted from 5 g of inoculum using the PowerMax  Soil DNA Isolation Kit (Qiagen, The Netherlands) with minor modifications following Gazol et al. (2016). AM fungal sequences were amplified from DNA extracts using AM fungal specific primers for the smallsubunit (SSU) ribosomal RNA gene: WANDA (Dumbrell et al. 2011) and AML2 (Lee et al. 2008). The samples were sequenced on the Illumina MiSeq platform, using a 2 x 300 bp pairedread sequencing approach (see Vahter et al. (2022) for more details), at Asper Biogene (Tartu, Estonia).
