Rhizosphere soil was collected from spinach (Spinacia oleracea L.) grown in untreated control soil. Total genomic DNA was extracted from 0.5 g of soil using the DNeasy PowerSoil Kit (Qiagen, USA). The fungal ITS region was amplified using ITS1F (CTTGGTCATTTAGAGGAAGTAA) and ITS-2043R (GCTGCGTTCTTCATCGATGC) primers and sequenced on the Illumina MiSeq platform at QBiogen Laboratory, Chennai, India.
