a,b, 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 coloured based on their phylogenetic affiliation at the phylum level.
