dsr operons of MAGs with carbon fixation potential. (a) Phylogenetic analysis of the concatenated DsrAB proteins. The detailed tree is provided in Fig. S6. Bootstrap values were based on 100 replicates, and only bootstrap values higher than 50% are shown, with red (between 50% and 75%) and black (≥75%) circles. (b) The dsr operon structure in 48 putative autotrophic MAGs. The number of MAGs containing a specific dsr operon structure is shown within parentheses.
