Fig. 3: Relative abundance of mercury transforming genes in sediment metagenomes and metatranscriptomes.

a Mean relative abundance of mercury-transforming genes extracted from MAGs in the 142 marine sediment metagenomes. The CPM values of the genes (details of genes shown in Supplementary Data 7) were calculated for the metagenomes of two groups (marginal sea and open ocean) (Supplementary Data 1 and 2). Error bars represent the standard error of the mean. Statistical significance between the two groups was determined using the two-sided Wilcoxon test. b The transcripts per million (TPM) reads of metabolic genes extracted from MAGs in the three metatranscriptomes for three layers of CD-T3L11 core from Challenger Deep of the Mariana Trench.
