The expression of marker genes for the main metabolic pathways of Sulfurimonas sp. from Gakkel Ridge plumes (Aurora and Polaris) and reference seawater. The gene expression is centred log-ratio transformed (clr). Differential expression of genes between the plumes of Aurora (n = 3) and Polaris (n = 6) is reported as log2-fold-change (log2FC). The pairwise statistical test is based on quantile-adjusted conditional maximum-likelihood (qCML) method and the likely value was adjusted by applying FDR. *Padjust < 0.05; **Padjust < 0.01; ***Padjust < 0.001. hydB: (NiFe)-hydrogenase Group 1b, large subunit; fccB: flavocytochrome c sulfide dehydrogenase; sqr: sulfide:quinone reductase; soxA, soxB, soxC: sulfur oxidation proteins; sorA: sulfite dehydrogenase; psrA: polysulfide reductase, subunit I; qoxB: cytochrome c oxidase, caa3-type, subunit I; ccoN: cytochrome c oxidase, cbb3-type, subunit I; hhe-1 and hhe-2: bacteriohemerythrins; porA: pyruvate:ferredoxin oxireductase, subunit I; oorA: oxoglutarate:ferredoxin oxireductase, subunit I; aclA: ATP-dependent citrate lyase, subunit I; fdrA: fumarate reductase, subunit I; fur: iron uptake regulation; feoA: Fe2+ uptake; znuA: Mn2+/Zn2+ uptake; tonB: siderophore transport; cft: ferritin; 1Fe-SOR and TAT-SOR: superoxide reductases; ccp: cytochrome c peroxidase; tpx, bcp and prxq: peroxiredoxins; cspG: cold shock-like protein; fliC: flagellin; rTCA: reductive tricarboxylic acid cycle.
