Uncultured Glomeromycotina partial 18S rRNA gene, isolate Gr_CON_R1_PR4
DNA was extracted from 5 g of dried soil using a PowerMax Soil DNA Isolation Kit following Gazol et al. (2016). AM fungal sequences were amplified from soil 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). Sequencing was done on the Illumina MiSeq platform, using a 2  300 bp pairedread sequencing approach, at Asper Biogene (Tartu, Estonia).
