NovaSeq of soil metagenome
DNA extraction was performed with the FastDNA Spin kit for soil (MP Biomedicals) and were normalized to 0.3 ng.L-1 before PCR amplification.  Primers AMADf (5 GGGAGGTAGTGACAATAAATAAC 3) and AMADGr (5 CCCAACTATCCCTATTAATCAT 3) were used to amplify the 18S rRNA gene.  Libraries sequencing was performed on a 2x250 NovaSeq 6000 by Fasteris SA (Switzerland).
