Fig. 6: Metabolic preference and activity of H2-consuming and H2-producing genomes.

Predicted sugar-acid-preference values (a) and GC contents (b) of H2-cycling populations. Colored dots indicate genomes in two groups (n = 55 and n = 36). Box plots show lower and upper quartiles, and median values in each genome group. Whiskers indicate maximum and minimum values excluding outliers. Statistical differences were calculated using the Wilcoxon rank sum test. c Differential activities of genomes involved in H2 cycling. Differential activities were calculated by subtracting overall transcriptional activities in PSY1 rice genotypes from those in Kitaake. Colored dots indicate genomes in different rice growth stages. Box plots show the same information as in (a, b). Median differential activities were statistically compared to zero using a one-sample Wilcoxon Signed Rank Test.
