(a) Phylogenomic analysis of 432 Proteobacteria MAGs and 43 Planctomycetes MAGs in the non-redundant genomic database (including the nine HBDs) using a collection of 37 phylogenetic marker gene families. Layers surrounding the phylogenomic tree indicate genome size and taxonomy of each MAG at the phylum and class level. (b) Functional network of the nine HBDs based upon a total of 5,912 identified gene functions. Size and colour of genomic nodes represent the number of detected functions and MAG taxonomy, respectively. The colour of functional nodes indicates their occurrence in the different HBDs.</div><div><br></div><div>Figure 2: Phylogeny of nitrogen fixation genes. Phylogenetic analysis of NifD (a) and NifH (b) occurring in the 15 nitrogen fixing MAGs (including five redundant MAGs and Ca. A. talassum) we identified from TARA Oceans in relation to 252 and 316 reference proteins, respectively. MAGs are colored based on their phylogenetic affiliation at the phylum level. </div><div><br></div><div>Figure 3: Abundance of nitrogen-fixing populations of Planctomycetes and Proteobacteria in the surface ocean. Box-plots in the top panel display the square-root-normalized cumulative relative distribution of the Planctomycetes (n=2) and Proteobacteria (n=7) HBDs in 93 metagenomes corresponding to 12 marine geographic regions (*: assuming that each liter in the surface ocean contains 0.5 billion archaeal and bacterial cells). Boxplots correspond to the first quartile, median and third quartile of distribution values with whiskers of 1.5x interquartile range. The maps in the bottom panel show the niche partitioning of HBD-06, HBD-07, HBD-08 and HBD-09 at the surface of four oceans and two seas (61 metagenomes from surface samples).</div><div><br></div><div>Figure 4: Relative abundance of the TARA Oceans nifH genes in the context of reference collections and amplicons. Violin plots are summarizing the average mean coverage of nifH genes retrieved in this study, nifH reference databases and nifH amplicon sequences from a large-scale survey across 93 TARA Oceans metagenomes using a competitive read recruitment strategy. The 18 nifH genes retrieved in this study were separated into two groups (‘HBD genomes’ and ‘Orphan genes’ for which we only have a scaffold) and compared to a database of nifH gene sequences. For each gene sequence, the coverage values were corrected by excluding nucleotide positions with coverage in the 1st and 4th quartiles to minimize the effect of non-specific mapping. </div></div><div><br></div><div><div><br></div><div><div>Figure S1: Phylogenetic analysis of nifH genes.
