MISeqv2 of Kit blank: DNeasy Plant
Kit blanks were loft open to capture lab microbes during extraction.  Material was extracted using Plant DNeasy kit with standard manufacture protocol and an extended lyses step. We amplified the ITS2 region using the fungal specific primers ITS9 (GAACGCAGCRAAIIGYGA; [41]) and ITS4 (TCCTCCGCTTATTGATATGC [42]).
