The assembled sequences were binned using MetaBAT2 v2.12.1 (Kang et al., 2019) and CONCOCT v1.1.0 (Alneberg et al., 2014), applying a contig length cut-off of 1.5 kb. The resulting bin sets were refined with the metaWRAP Bin_refinement module (parameters: -c 50) (Uritskiy et al., 2018). All generated bins were combined and dereplicated to create a non-redundant set of MAGs using dRep v3.2.2 (parameters: -comp 50 -con 10 --P_ani 0.9 --S_ani 0.98) (Olm et al., 2017) at 98% average nucleotide identities.</p><p dir="ltr">The identification of diazotroph MAGs was conducted using the Diaiden pipeline (<a href="https://github.com/jchenek/Diaiden" target="_blank">https://github.com/jchenek/Diaiden</a>).</p>
