Fig. 1: Functional diversity of metagenome-assembled genomes based on 95% average nucleotide identity (MAGs95%ANI) associated with sponge tissue, macroalgae biofilms and seawater.

a Total number of MAGs95%ANI discovered within each bacterial and archaeal phylum (class for Proteobacteria). b Non-metric multidimensional scaling plot (NMDS) based on binary Bray Curtis similarity index displaying the functional variability between sponge, algae and seawater MAGs. c The average composition of KEGG Modules associated with MAGs for each habitat. The three most abundant categories are shown individually as well as the unique category “Biosynthesis of other secondary metabolites” associated with macroalgae MAGs. The other eight categories are summarised as “Others”. d The absolute number of unique and shared KEGG Modules between sponge, macroalgae and seawater MAGs95%ANI for carbohydrate metabolism, energy metabolism and environmental information processing (from left to right).
