Fig. 3: Distribution of sods amongst marine ecosystems.
a Whisker box plots showing gene abundance of different sod isoforms of cyanobacteria in metagenomes (orange, nmg = 139) and metatranscriptomes (dark cyan, nmt = 162) generated from TARA oceans global marine survey. Data are presented by Pi (<0.1 µM, nmg = 39, nmt = 40; 0.1 ~ 0.5 µM, nmg = 49, nmt = 60; 0.5 ~ 1.0 µM, nmg = 26, nmt = 34; >1.0 µM, nmg = 25, nmt = 28) concentrations. The abundance of each sod was calculated by dividing the sum of the abundances of their homologs by the sum of total gene abundance from all reads in the sample. The whiskers extend to 1.5 × the interquartile range beyond the first and third quartiles (boxes). Exclusive median (line), average (triangle), and atypical values (circles) are also indicated. Different letters above the bars represent statistical significance (P < 0.05) calculated by Kruskal-Wallis between treatments. b Plots of the relative sods abundance in metatranscriptomes vs. the relative level of pstS transcripts. The data were plotted on a logarithmic scale. The red lines indicate linear regressions of the data points, and the significance of each regression is shown in each panel. Source data are provided as a Source Data file.
