Supplementary tables A–Q.

Table A in S2 Appendix. Genome features of SCM recovered from LSSM MMB as well as available reference genomes. Table B in S2 Appendix. List of accession numbers used for 16S rRNA phylogenetic analysis. Table C in S2 Appendix. Identification of common single copy genes across all SCMs and reference genomes used to make phylogenomic tree. Genes shown in green were used to construct the phylogenetic tree in Fig 2. Table D in S2 Appendix. List of researchers and location as well as etymologies for MMB species. Table E in S2 Appendix. Analysis of clonality within individual MMB. Table F in S2 Appendix. Analysis of synonymous verses non-synonymous mutations within SCMs. Table G in S2 Appendix. Metabolic pathway and functional annotations for SCMs from IMG annotations. Absence of gene in a specific SCM is denoted by a—symbol. Locus tag is listed for each gene present in SCM. Table H in S2 Appendix. Raman wavenumbers corresponding to biomolecules. Table I in S2 Appendix. List of FISH probes. All probes bind at positions 1032–1049 (using E. coli 16S rRNA as reference) and compete with each other for their binding site. See S9 Fig, S10 Fig, and S12 Fig for examples of FISH. Table J in S2 Appendix. NanoSIMS data for in situ experiments showing taxonomy via FISH as well as substrate amendments. Table K in S2 Appendix. NanoSIMS data for in vitro experiments comparing hotspots to whole consortium and controls. Table L in S2 Appendix. Relative radii and fluorescence intensity for BONCAT showing heterogeneity in anabolic activity within individual MMB consortia. Values determined using Eman2. Table M in S2 Appendix. Media recipe for cultivation of MMB. Table N in S2 Appendix. Water chemistry of LSSM sample site at 2 time points. Water collected above sediment during low tide. Table O in S2 Appendix. Comparative analysis of magnetosome genes using a BLAST of Candidatus Desulfamplus magnetomortis BW-1 magnetosome gene cluster genes against each SCM and the available reference genomes. Table P in S2 Appendix. Fractional abundance data for MMB groups analyzed by depth in LSSM for S9 Fig. Count adjusted (Corrected Count) for volume of original sample. Table Q in S2 Appendix. Relative fluorescence intensity calculations for BONCAT experiment shown in S10 Fig.
