Phylogenetic placement of RuBisCO sequences from surface and SCM samples. RuBisCO large subunit (rbcL) maximum likelihood tree with phylogenetic placement of 2631 metatranscriptome-derived open reading frames. Bootstrap support values are shown when ⩾50%. Thick branches indicate bootstrap support ⩾90%. Bubble sizes are proportion to the average of the rarefied abundances of the surface and SCM samples.
